Principles of Consolidation The consolidated financial statements include the accounts of the Company and its subsidiaries that are consolidated in conformity with U.S. GAAP. All intercompany amounts and transactions have been eliminated in consolidation. Cash and Cash Equivalents The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.Concentration of Credit Risk The Company maintains the majority of its domestic cash in one commercial bank in multiple operating and investment accounts. Balances on deposit are insured by the Federal Deposit Insurance Corporation (FDIC) up to specified limits. Balances in excess of FDIC limits are uninsured.One approximately 7% and 9% of accounts receivable at December 31, 2017 and 2016, respectively. No one customer accounted for greater than 6%, 7% and 7%, of net sales during the years ended December 31, 2017, 2016, or 2015, respectively.Accounts Receivable Receivables are recorded at their face value amount less an allowance for doubtful accounts. The Company estimates and records an allowance for doubtful accounts based on specific identification and historical experience. The Company writes off uncollectible accounts against the allowance for doubtful accounts after all collection efforts have been exhausted. Sales are generally made on an unsecured basis. Inventories Inventories are stated at the lower of cost or market, with cost determined generally using the first -in, first -out method.Property and Equipment Property and equipment are recorded at cost and are being depreciated using the straight-line method over the estimated useful lives of the assets, which are summarized below (in years). Costs of leasehold improvements are amortized over the lesser of the term of the lease (including renewal option periods) or the estimated useful lives of the improvements.
Total depreciation expense was $23,127, $21,465, and $16,742 for the years ended December 31, 2017, 2016, and 2015, respectively.Goodwill and Other Indefinite-Lived Intangible Assets Goodwill represents the excess of the purchase price over fair value of identifiable net assets acquired from business acquisitions. Goodwill is not amortized, but is reviewed for impairment on an annual basis and between annual tests if indicators of impairment are present. The Company evaluates goodwill for impairment annually as of October 31 or more frequently when an event occurs or circumstances change that indicates the carrying value may not be recoverable. The Company has the option to assess goodwill for impairment by performing either a qualitative assessment or quantitative test. The qualitative assessment determines whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then the quantitative test is not required to be performed. If the Company determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the Company is required to perform the quantitative test. In the quantitative test, the calculated fair value of the reporting unit is compared to its book value including goodwill. If the fair value of the reporting unit is in excess of its book value, the related goodwill is not impaired. If the fair value of the reporting unit is less than its book value, an impairment loss is recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. Other indefinite-lived intangible assets consist of certain tradenames. The Company tests the carrying value of these tradenames annually as of October 31 or more frequently when an event occurs or circumstances change that indicates the carrying value may not be recoverable by comparing the assets’ fair value to its carrying value. Fair value is measured using a relief-from-royalty approach, which assumes the fair value of the tradename is the discounted cash flows of the amount that would be paid had the Company not owned the tradename and instead licensed the tradename from another company.The Company performed the required annual impairment tests for goodwill and other indefinite-lived intangible assets for the fiscal years 201 7, 2016 and 2015, and found no 2017 and 2016 tests. There were no reporting units with a carrying value at-risk of exceeding fair value as of the October 31, 2017 impairment test date.After performing the impairment tests for fiscal year 2015, the Company determined that the fair value of the Ottomotores reporting unit was less than its carrying value, resulting in a non-cash goodwill impairment charge in the fourth quarter of 2015 of $4,611 to write-down the balance of the Ottomotores goodwill. The decrease in fair value of the Ottomotores reporting unit was due to several factors in the second half of 2015: the continued challenges of the Latin American economies, devaluation of the Peso against the U.S. Dollar, the slow development of Mexican energy reform as a result of decreasing oil prices; combining to cause 2015 results to fall short of prior expectations and future forecasts to decrease. The fair value was determined using a discounted cash flow analysis, which utilized key financial assumptions including the sales growth factors discussed above, a 3% terminal growth rate and a 15.7% discount rate.In the fourth quarter of 2015, the Company’s Board of Directors approved a plan to strategically transition and consolidate certain of the Company’s brands acquired in acquisitions to the Generac® tradename. This brand strategy change resulted in a reclassification to a two year remaining useful life for the impacted tradenames, causing the fair value to be less than the carrying value using the relief-from-royalty approach in a discounted cash flow analysis. As such, a $36,076 non-cash impairment charge was recorded to write-down the impacted tradenames to net realizable value. Other than the impairment charges discussed above, the Company found no other impairment when performing the required annual impairment tests for goodwill and other indefinite-lived intangible assets for fiscal year 2015. There can be no assurance that future impairment tests will not result in a charge to earnings.Impairment of Long-Lived Assets The Company periodically evaluates the carrying value of long-lived asset s (excluding goodwill and indefinite-lived tradenames). Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the sum of the expected future undiscounted cash flows is less than the carrying amount of an asset, a loss is recognized for the difference between the fair value and carrying value of the asset. Debt Issuance Costs Debt discounts and d irect costs incurred in connection with the issuance of long-term debt are deferred and recorded as a reduction of outstanding debt and amortized to interest expense using the effective interest method over the terms of the related credit agreements. $ 3,516, $3,939, and $5,429 of deferred financing costs and original issue discount were amortized to interest expense during fiscal years 2017, 2016 and 2015, respectively. Excluding the impact of any future long-term debt issuances or prepayments, estimated amortization to interest expense for the next five years is as follows: 2018 - $4,798; 2019 - $4,982; 2020 - $4,936; 2021 - $4,931; 2022 - $5,099. Income Taxes The Company is a C Corporation and therefore accounts for income taxes pursuant to the liability method. Accordingly, the current or deferred tax consequences of a transaction are measured by applying the provision of enacted tax laws to determine the amount of taxes payable currently or in future years. Deferred income taxes are provided for temporary differences between the income tax bases of assets and liabilities and their carrying amounts for financial reporting purposes. In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the years in which those temporary differences become deductible. The Company considers taxable income in prior carryback years, the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies, as appropriate, in making this assessment.Revenue Recognition Sales, net of estimated returns and allowances, are recognized upon shipment of product to the customer, which is generally when title passes, the Company has no further obligations, and the customer is required to pay subject to agreed upon payment terms. The Company, at the request of certain customers, will warehouse inventory billed to the customer but not delivered. Unless all revenue recognition criteria have been met, the Company does not recognize revenue on these transactions until the customers take possession of the product. In these cases, the funds collected on product warehoused for these customers are recorded as a customer advance until the customer takes possession of the product and the Company’s obligation to deliver the goods is completed. Customer advances are included in accrued liabilities in the consolidated balance sheets.The Company provides for certain estimated sales programs, discounts and incentive expenses which are recognized as a reduction of sales. Shipping and Handling Costs Shipping and handling costs billed to customers are included in net sales, and the related costs are included in cost of goods sold in the consolidated statements of comprehensive income. Advertising and Co-Op Advertising Expenditures for advertising, included in selling and service expenses in the consolidated statements of comprehensive income, are expensed as incurred. Total expenditures for advertising were $45,926, $45,488, and $39,258 for the years ended December 31, 2017, 2016, and 2015, respectively.Research and Development The Company expenses research and development costs as incurred. Total expenditures incurred for research and development were $42,925, $37,229, and $32,922 for the years ended December 31, 2017, 2016 and 2015, respectively.Foreign Currency Translation and Transactions Balance sheet amounts for non-U.S. Dollar functional currency businesses are translated into U.S. Dollars at the rates of exchange in effect at the end of the fiscal year. Income and expenses incurred in a foreign currency are translated at the average rates of exchange in effect during the year. The related translation adjustments are made directly to accumulated other comprehensive loss, a component of stockholders’ equity, in the consolidated balance sheets. Gains and losses from foreign currency transactions are recognized as incurred in the consolidated statements of comprehensive income. Fair Value of Financial Instruments ASC 820 -10 , Fair Value Measurement , defines fair value, establishes a consistent framework for measuring fair value, and expands disclosure for each major asset and liability category measured at fair value on either a recurring basis or nonrecurring basis. ASC 820 -10 clarifies that fair value is an exit price, representing the amount that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the pronouncement establishes a three -tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: (Level 1 ) observable inputs such as quoted prices in active markets; (Level 2 ) inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and (Level 3 ) unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.The Company believes the carrying amount of its financial instruments (cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities, short-term borrowings and ABL facility borrowings), excluding Term Loan borrowings, approximates the fair value of these instruments based upon their short-term nature. The fair value of Term Loan borrowings, which have an aggregate carrying value of $902,959, was approximately $903,500 (Level 2 ) at December 31, 2017, as calculated based on independent valuations whose inputs and significant value drivers are observable.For the fair value of the assets and liabilities measured on a recurring basis, refer to the fair value table in Note 4, “Derivative Instruments and Hedging Activities,” to the consolidated financial statements. The fair value of all derivative contracts is classified as Level 2. The valuation techniques used to measure the fair value of derivative contracts, all of which have counterparties with high credit ratings, were based on quoted market prices or model driven valuations using significant inputs derived from or corroborated by observable market data. The fair value of derivative contracts considers the Company’s credit risk in accordance with ASC 820 -10. Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Derivative Instruments and Hedging Activities The Company records all derivatives in accordance with ASC 815, Derivatives and Hedging , which requires derivative instruments be reported on the consolidated balance sheets at fair value and establishes criteria for designation and effectiveness of hedging relationships. The Company is exposed to market risk such as changes in commodity prices, foreign currencies and interest rates. The Company does not hold or issue derivative financial instruments for trading purposes.Share-Based Compensation Share-based compensation expense, including stock options and restricted stock awards, is generally recognized on a straight-line basis over the vesting period based on the fair value of awards which are expected to vest. The fair value of all share-based awards is estimated on the date of grant. New Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014 -09, Revenue from Contracts with Customers . This guidance is the culmination of the FASB’s joint project with the International Accounting Standards Board to clarify the principles for recognizing revenue. The core principal of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance provides a five -step process that entities should follow in order to achieve that core principal. ASU 2014 -09, as amended by ASU 2015 -14, Revenue from Contracts with Customers (Topic 606 ): Deferral of the Effective Date , ASU 2016 -08, Revenue from Contracts with Customers (Topic , ASU 606 ): Principal versus Agent Considerations2016 -10, Revenue from Contracts with Customers (Topic 606 ): Identifying Performance Obligations and Licensing, ASU 2016 -12, Revenue from Contracts with Customers (Topic 606 ): Narrow- Scope Improvements and Practical Expedients , and ASU 2016 -20, Technical Corrections and Improvements to Topic , becomes effective for the Company in 606, Revenue from Contracts with Customers2018. The guidance can be applied either on a full retrospective basis or on a modified retrospective basis in which the cumulative effect of initially applying the standard is recognized at the date of initial application. The Company has completed its assessment of the impacts the standard will have on its financial statements, and determined that the adoption does not have a material impact. In all material respects, the Company has identified a similar amount of performance obligations under the new guidance as compared with deliverables previously identified. As a result, the timing of revenue recognition will generally remain the same. The Company adopted the standard January 1, 2018 and will use the full retrospective method.In February 2016, the FASB issued ASU 2016 -02, Leases . This guidance is being issued to increase transparency and comparability among organizations by requiring the recognition of lease assets and lease liabilities on the balance sheet and by disclosing key information about leasing arrangements. The guidance should be applied using a modified retrospective approach and is effective for the Company in 2019, with early adoption permitted. The Company is currently assessing the impact the adoption of this guidance will have on the Company’s results of operations and financial position.In August 2016, the FASB issued ASU 2016 -15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments . This guidance is being issued to decrease diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This guidance should be applied on a retrospective basis and is effective for the Company in 2018, with early adoption permitted. The Company does not believe that the adoption of this guidance will have a significant impact on the presentation of the statement of cash flows. In January 2017, the FASB issued ASU 2017 -04, Intangibles – Goodwill and Other: Simplifying the Test for Goodwill Impairment . This guidance was issued to simplify the subsequent measurement of goodwill by eliminating Step 2 of the goodwill impairment test. Under the new guidance, the recognition of a goodwill impairment charge is calculated based on the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. This guidance should be applied on a prospective basis and is effective for the Company in 2020. The Company has early adopted this standard, which did not have a significant impact on its consolidated financial statements. In August 2017, the FASB issued ASU 2017 -12, Derivatives and Hedging – Targeted Improvements to Accounting for Hedging Activities . This guidance was issued to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements, and to make certain targeted improvements to simplify the application of the hedge accounting guidance. For existing hedges, this guidance should be applied using a cumulative effect adjustment, while the presentation and disclosure guidance should be adopted on a prospective basis. The standard is effective for the Company in 2019, with early adoption permitted. The Company is currently assessing the impact the adoption of this guidance will have on the Company’s results of operations and financial position.In the first quarter of 2017, the Company adopted ASU 2016 -09, Compensation – Stock Compensation: Improvements to Employee Share-Based Payment Accounting . The primary impact of adoption is the prospective recognition of excess tax benefits or deficiencies within the provision for income taxes on the consolidated statement of comprehensive income rather than within additional paid-in capital on the consolidated balance sheet. Further, the Company has elected to continue to estimate forfeitures expected to occur to determine the amount of stock compensation expense recognized each period. The Company also elected to apply the presentation requirements for cash flows related to excess tax benefits or deficiencies prospectively. The presentation requirements for cash flows related to employee taxes paid in exchange for withheld shares had no impact to any period presented on the consolidated statements of cash flows as such cash flows have historically been presented as a financing activity. There were no cumulative effect adjustments made to equity as of the beginning of the fiscal period, as those provisions of ASU 2016 -09 were not applicable or had no impact to the Company. There are several other new accounting pronouncements issued by the FASB. Each of these pronouncements, as applicable, has been or will be adopted by the Company. Management does not believe any of these accounting pronouncements has had or will have a material impact on the Company’s consolidated financial statements. |

Acquisition of Pramac On March 1, 2016, the Company acquired a 65% ownership interest in Pramac for a purchase price, net of cash acquired, of $60, 250. Headquartered in Siena, Italy, Pramac is a leading global manufacturer of stationary, mobile and portable generators primarily sold under the Pramac® brand. Pramac products are sold in over 150 countries through a broad distribution network. The acquisition purchase price was funded solely through cash on hand. The 35% noncontrolling interest in Pramac had an acquisition date fair value of $34,253, and was recorded as a redeemable noncontrolling interest in the consolidated balance sheet, as the noncontrolling interest holder has within its control the right to require the Company to redeem its interest in Pramac. The noncontrolling interest holder has a put option to sell their interests to the Company any time within five years from the date of acquisition. The put option price is either (i) a fixed amount if voluntarily exercised within the first two years after the acquisition, or (ii) based on a multiple of earnings, subject to the terms of the acquisition. Additionally, the Company holds a call option that it may redeem commencing five years from the date of acquisition, or earlier upon the occurrence of certain circumstances. The call option price is based on a multiple of earnings that is subject to the terms of the acquisition. Both the put and call option only provide for the complete transfer of the noncontrolling interest, with no partial transfers of interest permitted. The redeemable noncontrolling interest is recorded at the greater of the initial fair value, increased or decreased for the noncontrolling interests ’ share of comprehensive net income (loss), or the estimated redemption value, with any adjustment to the redemption value impacting retained earnings, but not net income. However, the redemption value adjustments are reflected in the earnings per share calculation, as detailed in Note 12, “Earnings Per Share,” to the consolidated financial statements. The following table presents the changes in the redeemable noncontrolling interest:
The Company finalized the Pramac purchase price allocation during the first quarter of 2017, based upon its estimates of the fair value of the acquired assets and assumed liabilities. The final purchase price allocation as of the balance sheet date was as follows:
The goodwill ascribed to this acquisition is not deductible for tax purposes. The accompanying consolidated financial statements include the results of Pramac from the date of acquisition through December 31, 2017. Acquisition of CHP On August 1, 2015, the Company acquired CHP for a purchase price, net of cash acquired, of $74,570. Headquartered in Vergennes, Vermont, CHP is a leading manufacturer of high-quality, innovative, professional-grade engine powered equipment used in a wide variety of property maintenance applications, with sales primarily in North America. The acquisition purchase price was funded solely through cash on hand. The Company finalized the CHP purchase price allocation during the fourth quarter of 2015 based upon its estimates of the fair value of the acquired assets and assumed liabilities. As a result, the Company recorded approximately $75,174 of intangible assets, including approximately $36,284 of goodwill, as of the acquisition date. The goodwill ascribed to this acquisition is not deductible for tax purposes. In addition, the Company assumed $12,000 of debt along with this acquisition. The accompanying consolidated financial statements include the results of CHP from the date of acquisition through December 31, 2017. Pro Forma Information The following unaudited pro forma information of the Company gives effect to these acquisitions as though the transactions had occurred on January 1, 2015. Consolidated net sales on a pro forma basis for the years ended December 31, 2016 and 2015 were $1,473,799 and $1,566,459, respectively. The pro forma impact of these acquisitions on net income and earnings per share for both the years ended December 31, 2016 and 2015 is not significant due to amortization related to acquired intangible assets and the fair value step-up of inventory in purchase accounting. This unaudited pro forma information is presented for informational purposes only and is not necessarily indicative of the results of operations that actually would have been achieved had the acquisitions been consummated on January 1, 2015. |

Commodities The Company is exposed to price fluctuations in commodities it uses as raw materials; primarily steel, copper and aluminum; and periodically utilizes commodity derivatives to mitigate the impact of these potential price fluctuations on its financial results and its economic well-being. These derivatives typically have maturities of less than eighteen months. At both December 31, 2017 and 2016, the Company had one Because these contracts do not qualify for hedge accounting, the related gains and losses are recorded in cost of goods sold in the Company’s consolidated statements of comprehensive income. Net pre-tax gains (losses) recognized were $377, $739 and $(1,909 ) for the years ended December 31, 2017, 2016, and 2015, respectively.Foreign Currencies The Company is exposed to foreign currency exchange risk as a result of transactions denominated in currencies other than the U.S. Dollar. The Company periodically utilizes foreign currency forward purchase and sales contracts to manage the volatility associated with certain foreign currency purchases and sales in the normal course of business. Contracts typically have maturities of twelve months or less. As of December 31, 2017 and 2016, the Company had twenty-eight and thirty-eight foreign currency contracts outstanding, respectively.Because these contracts do not qualify for hedge accounting, the related gains and losses are recorded in other, net in the Company’s consolidated statements of comprehensive income. Net pre-tax gains (losses) recognized for the years ended December 31, 2017, 2016 and 2015 were $697, $(385 ) and $(624 ), respectively. Interest Rate Swaps I n October 2013, the Company entered into two interest rate swap agreements; in May 2014, the Company entered into one interest rate swap agreement; and in 2017, the Company entered into twenty additional interest rate swap agreements. The Company formally documented all relationships between interest rate hedging instruments and the related hedged items, as well as its risk-management objectives and strategies for undertaking these hedge transactions. These interest rate swap agreements qualify as cash flow hedges, and accordingly, the effective portions of the gains or losses are reported as a component of accumulated other comprehensive loss (AOCL)in the consolidated balance sheets. The amount of gains (losses) recognized for the years ended December 31, 2017, 2016 and 2015 were $3,712, $535 and $(965 ), respectively. The cash flows of the swaps are recognized as adjustments to interest expense each period. The ineffective portions of the derivatives’ changes in fair value, if any, are immediately recognized in earnings.Fair Value The following table presents the fair value of the Company ’s derivatives:
The fair value of the co mmodity and foreign currency contracts are included in prepaid expenses and other assets, and the fair value of the interest rate swaps are included in other assets in the consolidated balance sheet as of December 31, 2017. The fair value of the commodity contract is included in other assets, the fair value of the foreign currency contracts are included in other accrued liabilities, and the fair value of the interest rate swaps are included in other long-term liabilities in the consolidated balance sheet as of December 31, 2016. Excluding the impact of credit risk, the fair value of the derivative contracts as of December 31, 2017 and 2016 is an asset of $4,703 and a liability of $1,295, respectively, which represents the amount the Company would receive or need to pay to exit the agreements on those dates. |

| Segment Reporting Disclosure [Text Block] |
The Company has two reportable segments for financial reporting purposes – Domestic and International. The Domestic segment includes the legacy Generac business and the impact of acquisitions that are based in the United States, all of which have revenues that are substantially derived from the U.S. and Canada. The International segment includes the Ottomotores, Tower Light, Pramac and Motortech acquisitions, all of which have revenues that are substantially derived from outside of the U.S and Canada. Both reportable segments design and manufacture a wide range of power generation equipment and other engine powered products. The Company has multiple operating segments, which it aggregates into the two reportable segments, based on materially similar economic characteristics, products, production processes, classes of customers and distribution methods. All segment information has been retrospectively applied to all periods presented to reflect the current reportable segment structure.
The Company's product offerings consist primarily of power generation equipment and other engine powered products geared for varying end customer uses. Residential products and commercial & industrial products are each a similar class of products based on similar power output and end customer. The breakout of net sales by product class between residential, commercial & industrial, and other products is as follows:
Management evaluates the performance of its segments based primarily on Adjusted EBITDA before noncontrolling interests, which is reconciled to Income before provision for income taxes below. The computation of Adjusted EBITDA is based on the definition that is contained in the Company’s credit agreements.
The following tables summarize additional financial information by reportable segment:
The Company ’s sales in the United States represent approximately 74%, 77%, and 85% of total sales for the years ended December 31, 2017, 2016 and 2015, respectively. Approximately 85% and 87% of the Company’s identifiable long-lived assets are located in the United States as of December 31, 2017 and 2016, respectively. |

Short-term borrowings are included in the consolidated balance sheets as follows:
Long-term borrowi ngs are included in the consolidated balance sheets as follows:
Maturities of long-term borrowings (before considering original issue discount and deferred financing costs) outstanding at December 31, 2017, are as follows:
The Company’s credit agreements originally provided for a $1,200,000 term loan B credit facility (Term Loan) and currently include a $300,000 uncommitted incremental term loan facility. In November 2016, the Company amended its Term Loan to extend the maturity date from May 31, 2020 to May 31, 2023. The Term Loan is guaranteed by all of the Company’s wholly-owned domestic restricted subsidiaries, and is secured by associated collateral agreements which pledge a first priority lien on virtually all of the Company’s assets, including fixed assets and intangibles, other than all cash, trade accounts receivable, inventory, and other current assets and proceeds thereof, which are secured by a second priority lien. The Term Loan initially bore interest at rates based upon either a base rate plus an applicable margin of 1.75% or adjusted LIBOR rate plus an applicable margin of 2.75%, subject to a LIBOR floor of 0.75%. Beginning in the second quarter of 2014, and measured each quarterly period thereafter, the applicable margin related to base rate loans was reduced to 1.50% and the applicable margin related to LIBOR rate loans is reduced to 2.50%, in each case, if the Company’s net debt leverage ratio, as defined in the Term Loan, falls below 3.00 to 1.00 for that measurement period.Because the Company ’s net debt leverage ratio was above 3.00 to 1.00 on July 1, 2015, it realized a 25 basis point increase in borrowing costs in the third quarter of 2015. As a result, the Company recorded a cumulative catch-up loss of $2,381 in the third quarter of 2015, which represented the additional cash interest expected to be paid while the net debt leverage ratio was expected to be above 3.00 to 1.00 using current forecasts at that time. The loss was recorded against original issue discount and deferred financing costs on long-term borrowings in the consolidated balance sheets and as a loss on change in contractual interest rate in the consolidated statement of comprehensive income. As the Company ’s net debt leverage ratio continued to be above 3.00 to 1.00 on July 1, 2016, the Company recorded a cumulative catch-up loss of $2,957 in the third quarter of 2016, which represented the additional cash interest expected to be paid while the net debt leverage ratio was expected to be above 3.00 to 1.00 using current forecasts at that time. The loss was recorded against original issue discount and deferred financing costs on long-term borrowings in the consolidated balance sheets and as a loss on change in contractual interest rate in the consolidated statement of comprehensive income.I n May 2015, the Company amended certain provisions and covenants of the Term Loan. In connection with this amendment and in accordance with ASC 470 -50, Debt Modifications and Extinguishments , the Company capitalized $1,528 of fees paid to creditors as deferred financing costs on long-term borrowings and expensed $49 of transaction fees in the second quarter of 2015. In November 2016, the Company amended its Term Loan to extend the maturity date from May 31, 2020 to May 31, 2023. In connection with this amendment and in accordance with ASC 470 -50, the Company capitalized $4,242 of fees paid to creditors as original issue discount and deferred financing costs on long-term borrowings and expensed $315 of transaction fees in the fourth quarter of 2016. In May 2017, the Company amended its Term Loan, modifying the pricing of the facility by reducing the applicable margin rates to base rate plus a fixed applicable margin of 1.25% or adjusted LIBOR rate plus a fixed applicable margin of 2.25%. Further, the amendment removed the pricing grid that would reduce the applicable margin if a net debt leverage ratio of 3.00 to 1.00 was achieved. As a result, the Company does not anticipate any future catch-up gains or losses resulting from changes in contractual interest rates to be recorded in the statements of comprehensive income. The amended Term Loan pricing is still subject to the 0.75% LIBOR floor. In connection with this amendment and in accordance with ASC 470 -50, the Company capitalized $1,432 of fees paid to creditors as deferred financing costs on long-term borrowings and expensed $85 of transaction fees in the second quarter of 2017. In December 2017, the Company amended its Term Loan, which further reduced the applicable margin rates to base rate plus a fixed applicable margin of 1.00% or adjusted LIBOR rate plus a fixed applicable margin of 2.00%. Additionally, the amendment eliminated the Excess Cash Flow payment requirement for 2017, and will eliminate future requirements if the Company’s secured leverage ratio is maintained below 3.75 to 1.00 times. In connection with this amendment and in accordance with ASC 470 -50, the Company capitalized $2,346 of fees paid to creditors as original issue discount and deferred financing costs on long-term borrowings and expensed $38 of transaction fees in the fourth quarter of 2017. As of December 31, 2017, the Company's secured leverage ratio was 2.50 to 1.00 times, and the Company was in compliance with all covenants of the Term Loan. There are no financial maintenance covenants on the Term Loan. T he Company’s credit agreements also originally provided for a $150,000 senior secured ABL revolving credit facility (ABL Facility). The maturity date of the ABL Facility originally was May 31, 2018. Borrowings under the ABL Facility are guaranteed by all of the Company’s wholly-owned domestic restricted subsidiaries, and are secured by associated collateral agreements which pledge a first priority lien on all cash, trade accounts receivable, inventory, and other current assets and proceeds thereof, and a second priority lien on all other assets, including fixed assets and intangibles of the Company and certain domestic subsidiaries. ABL Facility borrowings initially bore interest at rates based upon either a base rate plus an applicable margin of 1.00% or adjusted LIBOR rate plus an applicable margin of 2.00%, in each case, subject to adjustments based upon average availability under the ABL Facility. I n May 2015, the Company amended its ABL Facility (Amended ABL Facility). The amendment (i) increased the ABL Facility from $150,000 to $250,000 , (ii) extended the maturity date from May 31, 2018 to May 29, 2020, ( iii) increased the uncommitted incremental facility from $50,000 to $100,000, (iv) reduced the interest rate spread by 50 basis points and (v) reduced the unused line fee by 12.5 basis points across all tiers. Additionally, the amendment relaxes certain restrictions on the Company’s ability to, among other things, (i) make additional investments and acquisitions (including foreign acquisitions), (ii) make restricted payments and (iii) incur additional secured and unsecured debt (including foreign subsidiary debt). In connection with this amendment and in accordance with ASC 470 -50, the Company capitalized $540 of new debt issuance costs in 2015. I n May 2015, the Company borrowed $100,000 under the Amended ABL Facility, the proceeds of which were used as a voluntary prepayment towards the Term Loan. In the fourth quarter of 2017, the Company repaid the entire outstanding Amended ABL Facility balance. As of December 31, 2017, the Company had $249,650 of availability under the Amended ABL Facility, net of outstanding letters of credit.I n n March and May 2015, the Company made voluntary prepayments of the Term Loan of $50,000 and $100,000, respectively, which were applied to the Excess Cash Flow payment requirement in the Term Loan. As a result of the prepayments, the Company wrote off $4,795 of original issue discount and capitalized debt issuance costs during the year ended December 31, 2015 as a loss on extinguishment of debt in the consolidated statement of comprehensive income. Similarly, i November 2016, the Company made a voluntary prepayment of $25,000, which resulted in a $574 write-off of original issue discount and capitalized debt issuance costs during the year ended December 31, 2016 as a loss on extinguishment of debt. As of December 31, 201 7 and December 31, 2016, short-term borrowings consisted primarily of borrowings by our foreign subsidiaries on local lines of credit, which totaled $20,602 and $31,198, respectively. |

I n August 2015, the Company’s Board of Directors approved a $200,000 stock repurchase program, which the Company completed in the third quarter of 2016. In October 2016, the Company’s Board of Directors approved an additional $250,000 stock repurchase program. Under the second program, the Company may repurchase up to $250,000 of its common stock over the 24 months following the date of approval. The Company may repurchase its common stock from time to time, in amounts and at prices the Company deems appropriate, subject to market conditions and other considerations. The repurchase may be executed using open market purchases, privately negotiated agreements or other transactions. The actual timing, number and value of shares repurchased under the program will be determined by management at its discretion and will depend on a number of factors, including the market price of the Company’s common stock and general market and economic conditions, applicable legal requirements, and compliance with the terms of the Company’s outstanding indebtedness. The repurchases may be funded with cash on hand, available borrowings or proceeds from potential debt or other capital markets sources. The stock repurchase program may be suspended or discontinued at any time without prior notice. During the years ended December 31, 2017, 2016 and 2015, the Company repurchased 844,500, 3,968,706 and 3,303,500 shares of its common stock, respectively, for $30,012, $149,937 and $99,942, respectively, all funded with cash on hand. |

| Income Tax Disclosure [Text Block] |
The Company ’s provision for income taxes consists of the following:
The Company files U.S federal, U.S. state and foreign jurisdiction tax returns that are subject to examination up to the expiration of the statute of limitations. We believe the tax positions taken on our returns would be sustained upon an exam, or where a position is uncertain, adequate reserves have been recorded. As of December 31, 2017 the Company is no longer subject to income tax examinations for United States federal income taxes for the tax years prior to 2 014. Due to the carryforward of net operating losses, and research and development credits, the Company's Wisconsin state income tax returns for tax years 2007 through 2016 remain open. In addition, the Company is subject to audit by various foreign taxing jurisdictions for the tax years 2012 through 2016. The Company is currently under examination in multiple jurisdictions and is working to address all matters. While the Compa ny does not believe any material taxes or penalties are due, there is a possibility that the ultimate tax outcome of an examination may result in differences from what was recorded. Such differences may affect the provision for income taxes in the period in which the determination is made, and could impact the Company’s financial results.On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act makes broad and complex changes to the U.S. tax code, including, but not limited to, reducing the U.S. federal corporate tax rate from 35% to 21% , requiring companies to pay a one -time transition tax on certain unrepatriated earnings of foreign subsidiaries, eliminating certain deductions, introducing new tax regimes, changing how foreign earnings are subject to U.S. tax, and enhancing and extending through 2026 the option to claim accelerated depreciation deductions on qualified property.The SEC staff issued SAB 118, which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act.The Company's accounting for the following elements of the Tax Act is incomplete. However, reasonable estimates of certain effects were able to be made and, therefore, provisional adjustments were recorded as follows: Reduction of US federal corporate tax rate: The Tax Act reduces the federal corporate tax rate to 21% , effective January 1, 2018. For certain of the Company's deferred tax liabilities (DTLs), a provisional decrease of $28,434 was recorded to reflect our DTLs at thelower corporate tax rate, with a corresponding net adjustment to deferred income tax benefit of $28,434 for the year ended December 31, 2017. While a reasonable estimate of the impact of the reduction in the corporate tax rate was made, it may be affected by other analyses related to the Tax Act, including, but not limited to, the calculation of deemed repatriation of deferred foreign income and the state tax effect of adjustments made to federal temporary differences.Deemed Repatriation Transition Tax: ’s foreign subsidiaries. To determine the amount of the Transition Tax, the amount of post- 1986 E&P of relevant subsidiaries, as well as the amount of non-U.S. income taxes paid on such earnings must be determined, in addition to other factors. The Company made a reasonable estimate of the Transition Tax and has concluded the amount was not material.Cost recovery: While the Company has not yet completed all of the computations necessary or completed an inventory of our 2017 expenditures that qualify for immediate expensing, a provisional benefit of $700 was recorded based on our current intent to fully expense all qualifying expenditures. This resulted in a decrease of approximately $1,750 to current income tax payable and a corresponding increase in DTLs of approximately $1,050 (after considering the effects of the reduction in income tax rates).As the Company completes its analysis of the Tax Act; collects and prepares necessary data; and interprets any additional guidance issued by the U.S. Treasury Department, the IRS, and other standard-setting bodies; adjustments to the provisional amounts may be recorded.Global intangible low taxed income (GILTI): Because of the complexity of the new GILTI tax rules, the Company is continuing to evaluate this provision of the Tax Act and the application of ASC 740. Under U.S. GAAP, the Company is allowed to make an accounting policy choice of either (1 ) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred (the “period cost method”) or (2 ) factoring such amounts into a company’s measurement of its deferred taxes (the “deferred method”). The selection of an accounting policy with respect to the new GILTI tax rules will depend, in part, on analyzing the Company's global income to determine whether it is expected to have future U.S. inclusions in taxable income related to GILTI and, if so, what the impact is expected to be. Because whether the Company expects to have future U.S. inclusions in taxable income related to GILTI depends not only on the current structure and estimated future results of global operations but also on the intent and ability to modify the structure and/or the business; the Company is not yet able to reasonably estimate the effect of this provision of the Tax Act. Therefore, no adjustments related to potential GILTI tax have been made in the financial statements and no policy decision regarding whether to record deferred taxes on GILTI has been made.Significant components of deferred tax assets and liabilities are as follows:
As of December 31, 201 7 and 2016, deferred tax assets of $3,238 and $3,337, and deferred tax liabilities of $43,789 and $17,278, respectively, were reflected on the consolidated balance sheets. One of the Company's subsidiaries, Generac Brazil, has generated net operating losses for multiple years. The realizability of the deferred tax assets associated with these net operating losses is uncertain, therefore a valuation allowance has been recorded since Generac Brazil's acquisition on December 8, 2012 and continued through December 31, 2017. In addition, the Company recorded a valuation allowance in the opening balance sheet and as of December 31, 2017 and 2016 related to the Pramac acquisition. The valuation allowance represents a reserve for deferred tax assets, including loss carryforwards, of certain Pramac subsidiaries, for which utilization is uncertain.At December 31, 201 7, the Company had state research and development tax credit carryforwards, and state manufacturing tax credit carryforwards of approximately $13,089 and $4,618, respectively, which expire between 2018 and 2032. A valuation allowance of $1,171 has been established against deferred tax assets for these carryforwards. Changes in the Company ’s gross liability for unrecognized tax benefits, excluding interest and penalties, were as follows:
The unrecognized tax benefit as of December 31, 2017 and 2016, if recognized, would impact the effective tax rate.As of Interest and penalties are recorded as a component of income tax expense. December 31, 2017, 2016 and 2015, total accrued interest of approximately $131, $272 and $174, respectively, and accrued penalties of approximately $220, $425 and $363, respectively, associated with net unrecognized tax benefits are included in the Company’s consolidated balance sheets. T he Company does not expect a significant increase or decrease to the total amounts of unrecognized tax benefits related to continuing operations during the fiscal year ending December 31, 2018. The Tax Act includes a mandatory one -time tax on accumulated earnings of foreign subsidiaries, and as a result, all previously unremitted earnings for which no U.S. deferred tax liability had been accrued have now been subject to U.S. tax. Notwithstanding the U.S. taxation of these amounts, the Company intends to continue to invest these earnings, as well as the capital in these subsidiaries, indefinitely outside of the U.S. and do not expect to incur any significant, additional taxes related to such amounts.A reconciliation of the statutory tax rates and the effective tax rates for the years ended December 31, 2017 , 2016 and 2015 are as follows:

Medical and Dental Plan The Company maintains medical and dental benefit plans covering its full-time domestic employees and their dependents. Certain plans are partially or fully self-funded under which participant claims are obligations of the plan. These plans are funded through employer and employee contributions at a level sufficient to pay for the benefits provided by the plan. The Company’s contributions to the plans were $14,992, $15,019, and $14,352 for the years ended December 31, 2017, 2016, and 2015, respectively.The Company ’s foreign subsidiaries participate in government sponsored medical benefit plans. In certain cases, the Company purchases supplemental medical coverage for certain employees at these foreign locations . The expenses related to these plans are not material to the Company’s consolidated financial statements. S avings Plan The Company maintains a defined-contribution 401 (k) savings plan for eligible domestic employees. Under the plan, employees may defer receipt of a portion of their eligible compensation. The Company amended the 401 (k) savings plans effective January 1, 2009, to add Company matching and non-elective contributions. The Company may contribute a matching contribution of 50% of the first 6% of eligible compensation of employees. The Company may also contribute a non-elective contribution for eligible employees employed on December 31, 2008. Both Company matching contributions and non-elective contributions are subject to vesting. Forfeitures may be applied against plan expenses and company contributions. The Company recognized $3,600, $3,400 and $3,000 of expense related to these plans in 2017, 2016 and 2015, respectively. Pension Plans The Company has frozen noncontributory salaried and hourly pension plans (Pension Plans) covering certain domestic employees. The Pension Plans were frozen effective December 31, 2008. The benefits under the salaried plan are based upon years of service and the participants’ defined final average monthly compensation. The benefits under the hourly plan are based on a unit amount at the date of termination multiplied by the participant’s years of credited service. The Company’s funding policy for the Pension Plans is to contribute amounts at least equal to the minimum annual amount required by applicable regulations. The Company uses a December 31 measurement date for the Pension Plans. The accumulated benefit obligation, reconciliation of the changes in projected benefit obligation, changes in plan assets and the funded status of the Pension Plans are as follows:
The actuarial loss for the Pension Plans that was amortized from AOCL into net periodic (benefit) cost during 2017 is $883. The amount in AOCL as of December 31, 2017 that is expected to be recognized as a component of net periodic pension expense during the next fiscal year is $802. The components of net periodic pension cost are as follows:
Weighted-average assumptions used to determine the benefit obligations are as follows:
Weighted-average assumptions used to determine net periodic pension cost are as follows:
To determine the long-term rate of return assumption for the plans' assets, the Company studies historical markets and preserves the long-term historical relationships between equities and fixed-income securities consistent with the widely accepted capital market principle that assets with higher volatility generate a greater return over the long run. The Company evaluates current market factors such as inflation and interest rates before it determines long-term capital market assumptions and reviews peer data and historical returns to check for reasonableness and appropriateness. The Pension Plans ’ weighted-average asset allocation at December 31, 2017 and 2016, by asset category, is as follows:
The fair values of the Pension Plans ’ assets at December 31, 2017 are as follows:
The fair values of the Pension Pl ans' assets at December 31, 2016 are as follows:
A reconciliation of beg inning and ending balances for Level 3 assets for the years ended December 31, 2017 and 2016 is as follows:
Mutual Funds – This category includes investments in mutual funds that encompass both equity and fixed income securities that are designed to provide a diverse portfolio. The plans' mutual funds are designed to track exchange indices, and invest in diverse industries. Some mutual funds are classified as regulated investment companies. Investment managers have the ability to shift investments from value to growth strategies, from small to large capitalization funds, and from U.S. to international investments. These investments are valued at the closing price reported on the active market on which the individual securities are traded. These investments are classified within Level 1 of the fair value hierarchy.Other Investments – This category includes investments in limited partnerships and are valued at estimated fair value, as determined with the assistance of each respective limited partnership, based on the net asset value of the investment as of the balance sheet date, which is subject to judgment, and therefore is classified within Level 3 of the fair value hierarchy.The Company ’s target allocation for equity securities and real estate is generally between 65% - 85%, with the remainder allocated primarily to fixed income (bonds). The Company regularly reviews its actual asset allocation and periodically rebalances its investments to the targeted allocation when considered appropriate.At a minimum, the Company expects to make estimated contributions of $319 to the Pension Plans in 2018. The following benefit payments are expected to be paid from the Pension Plans:
Certain of the Company ’s foreign subsidiaries participate in local statutory defined benefit or other post-employment benefit plans. These plans provide benefits that are generally based on years of credited service and a percentage of the employee’s eligible compensation earned throughout the applicable service period. Liabilities recorded under these plans are included in accrued wages and employee benefits in the Company’s consolidated balance sheets and are not material. |

| Disclosure of Compensation Related Costs, Share-based Payments [Text Block] |
The Company adopted an equity incentive plan (Plan) on February 10, 2010 in connection with its initial public offering. The Plan, as amended, allows for granting of up to 9.1 million share-based awards to executives, directors and employees. Awards available for grant under the Plan include stock options, stock appreciation rights, restricted stock, other share-based awards and performance-based compensation awards. Total share-based compensation expense related to the Plan, net of estimated forfeitures, was $10,205, $9,493 and $8,241 for the years ended December 31, 2017, 2016 and 2015, respectively, which is recorded in operating expenses in the consolidated statements of comprehensive income.Stock Options - Stock options granted in 2017 have an exercise price between $40.12 per share and $48.98 per share; stock options granted in 2016 have an exercise price between $33.23 per share and $35.37 per share, and the stock options granted in 2015 have an exercise price between $28.36 per share and $49.70 per share. Stock options vest in equal installments over four years, subject to the grantee’s continued employment or service and expire ten years after the date of grant.S tock option exercises can be net-share settled such that the Company withholds shares with value equivalent to the exercise price of the stock option awards plus the employees’ minimum statutory obligation for the applicable income and other employment taxes. Total shares withheld were 9,033, 473,743 and 272,296 in 2017, 2016 and 2015, respectively, and were based on the value of the stock on the exercise dates. The net-share settlement has the effect of share repurchases by the Company as they reduce the number of shares that would have otherwise been issued.Employees can also utilize a cashless for cash exercise of stock options, such that all exercised shares will be sold in the market immediately. Cash equivalent to the exercise price of the awards plus the employees ’ minimum statutory tax obligations is remitted to the Company, with the remaining cash being transferred to the employee. Total proceeds from the cashless for cash exercise of stock options were $6,951 and $1,623 in 2017 and 2016, respectively, and are reflected as a financing activity in the consolidated statement of cash flows. Total payments made by the Company for the employees ’ tax obligations to the taxing authorities were $4,301, $13,056 and $9,768 in 2017, 2016 and 2015, respectively, and are reflected as a financing activity within the consolidated statements of cash flows.The grant-date fair value of each option grant is estimated using the Black-Scholes-Merton option pricing model. The fair value is then amortized on a straight-line basis over the requisite service period of the awards, which is generally the vesting period. Use of a valuation model requires management to make certain assumptions with respect to selected model inputs. Expected volatility is calculated based on an analysis of historic and implied volatility measures for a set of peer companies. The average expected life is based on the contractual term of the option using the simplified method. The risk-free interest rate is based on U.S. Treasury zero -coupon issues with a remaining term equal to the expected life assumed at the date of grant. The compensation expense recognized is net of estimated forfeitures. Forfeitures are estimated based on actual share option forfeiture history. The weighted-average assumptions used in the Black-Scholes-Merton option pricing model for 2017, 2016 and 2015 are as follows:
The Company periodically evaluates its forfeiture rates and updates the rates it uses in the determination of its share-based compensation expense. The impact of the change to the forfeiture rates on shares-based compensation expense was not material for the years ended December 31, 2017, 2016 and 2015. A summary of the Company ’s stock option activity and related information for the years ended December 31, 2017, 2016 and 2015 is as follows:
As of December 31, 201 7, there was $8,552 of total unrecognized compensation cost, net of expected forfeitures, related to unvested options. The cost is expected to be recognized over the remaining service period, having a weighted-average period of 2.5 years. Total share-based compensation cost related to the stock options for 2017, 2016 and 2015 was $4,503, $4,366 and $4,198, respectively, which is recorded in operating expenses in the consolidated statements of comprehensive income.Restricted Stock – Restricted stock awards vest in equal installments over three years, subject to the grantee’s continued employment or service. Certain restricted stock awards also include performance shares, which were awarded in the years 2014 through 2017. The number of performance shares that can be earned are contingent upon Company performance measures over a three -year period. Performance measures are based on a weighting of revenue growth and EBITDA margin, from which grantees may earn from 0% to 200% of their target performance share award. The performance period for the 2015 awards covers the years 2015 through 2017, the performance period for the 2016 awards covers the years 2016 through 2018, and the performance period for the 2017 awards covers the years 2017 through 2019. The Company estimates the number of performance shares that will vest based on projected financial performance. The fair market value of the restricted awards at the time of the grant is amortized to expense over the period of vesting. The fair value of restricted awards is determined based on the market value of the Company's shares on the grant date. The compensation expense recognized for restricted share awards is net of estimated forfeitures.Restricted stock vesting is net-share settled such that , upon vesting, the Company withholds shares with value equivalent to the employees’ minimum statutory obligation for the applicable income and other employment taxes, and then pays the cash to the taxing authorities on behalf of the employees. In effect, the Company repurchases these shares and classifies as treasury stock. Total shares withheld were 39,500, 28,593 and 65,763 in 2017, 2016 and 2015, respectively, and were based on the value of the stock on the vesting dates. Total payments made by the Company for the employees’ tax obligations to the taxing authorities were $1,591, $952 and $3,233 in 2017, 2016 and 2015, respectively, and are reflected as a financing activity within the consolidated statements of cash flows.A summary of the Company's restricted stock activity for the years ended December 31, 2017, 2016 and 2015 is as follows:
As of December 31, 2017, there was $7,702 of unrecognized compensation cost, net of expected forfeitures, related to non-vested restricted stock awards. That cost is expected to be recognized over the remaining service period, having a weighted-average period of 1.7 years. Total share-based compensation cost related to the restricted stock for 2017, 2016 and 2015 was $5,702, $5,127 and $4,043, respectively, which is recorded in operating expenses in the consolidated statements of comprehensive income.During 201 7, 2016 and 2015, 34,095, 19,326 and 16,260 shares, respectively, of stock were granted to certain members of the Company’s Board of Directors as a component of their compensation for their service on the Board, of which 22,762, 19,326 and 16,260 shares, respectively, were fully vested. Total share-based compensation cost for these share grants in 2017, 2016 and 2015 was $1,133, $670 and $615, respectively, which is recorded in operating expenses in the consolidated statements of comprehensive income. |

Total depreciation expense was $23,127, $21,465, and $16,742 for the years ended December 31, 2017, 2016, and 2015, respectively. |

| Goodwill and Intangible Assets, Policy [Policy Text Block] | Goodwill and Other Indefinite-Lived Intangible Assets Goodwill represents the excess of the purchase price over fair value of identifiable net assets acquired from business acquisitions. Goodwill is not amortized, but is reviewed for impairment on an annual basis and between annual tests if indicators of impairment are present. The Company evaluates goodwill for impairment annually as of October 31 or more frequently when an event occurs or circumstances change that indicates the carrying value may not be recoverable. The Company has the option to assess goodwill for impairment by performing either a qualitative assessment or quantitative test. The qualitative assessment determines whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then the quantitative test is not required to be performed. If the Company determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the Company is required to perform the quantitative test. In the quantitative test, the calculated fair value of the reporting unit is compared to its book value including goodwill. If the fair value of the reporting unit is in excess of its book value, the related goodwill is not impaired. If the fair value of the reporting unit is less than its book value, an impairment loss is recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. Other indefinite-lived intangible assets consist of certain tradenames. The Company tests the carrying value of these tradenames annually as of October 31 or more frequently when an event occurs or circumstances change that indicates the carrying value may not be recoverable by comparing the assets’ fair value to its carrying value. Fair value is measured using a relief-from-royalty approach, which assumes the fair value of the tradename is the discounted cash flows of the amount that would be paid had the Company not owned the tradename and instead licensed the tradename from another company.The Company performed the required annual impairment tests for goodwill and other indefinite-lived intangible assets for the fiscal years 201 7, 2016 and 2015, and found no 2017 and 2016 tests. There were no reporting units with a carrying value at-risk of exceeding fair value as of the October 31, 2017 impairment test date.After performing the impairment tests for fiscal year 2015, the Company determined that the fair value of the Ottomotores reporting unit was less than its carrying value, resulting in a non-cash goodwill impairment charge in the fourth quarter of 2015 of $4,611 to write-down the balance of the Ottomotores goodwill. The decrease in fair value of the Ottomotores reporting unit was due to several factors in the second half of 2015: the continued challenges of the Latin American economies, devaluation of the Peso against the U.S. Dollar, the slow development of Mexican energy reform as a result of decreasing oil prices; combining to cause 2015 results to fall short of prior expectations and future forecasts to decrease. The fair value was determined using a discounted cash flow analysis, which utilized key financial assumptions including the sales growth factors discussed above, a 3% terminal growth rate and a 15.7% discount rate.In the fourth quarter of 2015, the Company’s Board of Directors approved a plan to strategically transition and consolidate certain of the Company’s brands acquired in acquisitions to the Generac® tradename. This brand strategy change resulted in a reclassification to a two year remaining useful life for the impacted tradenames, causing the fair value to be less than the carrying value using the relief-from-royalty approach in a discounted cash flow analysis. As such, a $36,076 non-cash impairment charge was recorded to write-down the impacted tradenames to net realizable value. Other than the impairment charges discussed above, the Company found no other impairment when performing the required annual impairment tests for goodwill and other indefinite-lived intangible assets for fiscal year 2015. There can be no assurance that future impairment tests will not result in a charge to earnings. |
||||||||||||||||||||||||||||
| Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block] | Impairment of Long-Lived Assets The Company periodically evaluates the carrying value of long-lived asset s (excluding goodwill and indefinite-lived tradenames). Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the sum of the expected future undiscounted cash flows is less than the carrying amount of an asset, a loss is recognized for the difference between the fair value and carrying value of the asset. |

| Debt, Policy [Policy Text Block] | Debt Issuance Costs Debt discounts and d irect costs incurred in connection with the issuance of long-term debt are deferred and recorded as a reduction of outstanding debt and amortized to interest expense using the effective interest method over the terms of the related credit agreements. $ 3,516, $3,939, and $5,429 of deferred financing costs and original issue discount were amortized to interest expense during fiscal years 2017, 2016 and 2015, respectively. Excluding the impact of any future long-term debt issuances or prepayments, estimated amortization to interest expense for the next five years is as follows: 2018 - $4,798; 2019 - $4,982; 2020 - $4,936; 2021 - $4,931; 2022 - $5,099. |

| Income Tax, Policy [Policy Text Block] | Income Taxes The Company is a C Corporation and therefore accounts for income taxes pursuant to the liability method. Accordingly, the current or deferred tax consequences of a transaction are measured by applying the provision of enacted tax laws to determine the amount of taxes payable currently or in future years. Deferred income taxes are provided for temporary differences between the income tax bases of assets and liabilities and their carrying amounts for financial reporting purposes. In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the years in which those temporary differences become deductible. The Company considers taxable income in prior carryback years, the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies, as appropriate, in making this assessment. |

| Revenue Recognition, Policy [Policy Text Block] | Revenue Recognition Sales, net of estimated returns and allowances, are recognized upon shipment of product to the customer, which is generally when title passes, the Company has no further obligations, and the customer is required to pay subject to agreed upon payment terms. The Company, at the request of certain customers, will warehouse inventory billed to the customer but not delivered. Unless all revenue recognition criteria have been met, the Company does not recognize revenue on these transactions until the customers take possession of the product. In these cases, the funds collected on product warehoused for these customers are recorded as a customer advance until the customer takes possession of the product and the Company’s obligation to deliver the goods is completed. Customer advances are included in accrued liabilities in the consolidated balance sheets.The Company provides for certain estimated sales programs, discounts and incentive expenses which are recognized as a reduction of sales. |

| Foreign Currency Transactions and Translations Policy [Policy Text Block] | Foreign Currency Translation and Transactions Balance sheet amounts for non-U.S. Dollar functional currency businesses are translated into U.S. Dollars at the rates of exchange in effect at the end of the fiscal year. Income and expenses incurred in a foreign currency are translated at the average rates of exchange in effect during the year. The related translation adjustments are made directly to accumulated other comprehensive loss, a component of stockholders’ equity, in the consolidated balance sheets. Gains and losses from foreign currency transactions are recognized as incurred in the consolidated statements of comprehensive income. |

| Fair Value of Financial Instruments, Policy [Policy Text Block] | Fair Value of Financial Instruments ASC 820 -10 , Fair Value Measurement , defines fair value, establishes a consistent framework for measuring fair value, and expands disclosure for each major asset and liability category measured at fair value on either a recurring basis or nonrecurring basis. ASC 820 -10 clarifies that fair value is an exit price, representing the amount that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the pronouncement establishes a three -tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: (Level 1 ) observable inputs such as quoted prices in active markets; (Level 2 ) inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and (Level 3 ) unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.The Company believes the carrying amount of its financial instruments (cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities, short-term borrowings and ABL facility borrowings), excluding Term Loan borrowings, approximates the fair value of these instruments based upon their short-term nature. The fair value of Term Loan borrowings, which have an aggregate carrying value of $902,959, was approximately $903,500 (Level 2 ) at December 31, 2017, as calculated based on independent valuations whose inputs and significant value drivers are observable.For the fair value of the assets and liabilities measured on a recurring basis, refer to the fair value table in Note 4, “Derivative Instruments and Hedging Activities,” to the consolidated financial statements. The fair value of all derivative contracts is classified as Level 2. The valuation techniques used to measure the fair value of derivative contracts, all of which have counterparties with high credit ratings, were based on quoted market prices or model driven valuations using significant inputs derived from or corroborated by observable market data. The fair value of derivative contracts considers the Company’s credit risk in accordance with ASC 820 -10. |
||||||||||||||||||||||||||||
| Use of Estimates, Policy [Policy Text Block] | Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. |
||||||||||||||||||||||||||||
| Derivatives, Policy [Policy Text Block] | Derivative Instruments and Hedging Activities The Company records all derivatives in accordance with ASC 815, Derivatives and Hedging , which requires derivative instruments be reported on the consolidated balance sheets at fair value and establishes criteria for designation and effectiveness of hedging relationships. The Company is exposed to market risk such as changes in commodity prices, foreign currencies and interest rates. The Company does not hold or issue derivative financial instruments for trading purposes. |
||||||||||||||||||||||||||||
| Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block] | Share-Based Compensation Share-based compensation expense, including stock options and restricted stock awards, is generally recognized on a straight-line basis over the vesting period based on the fair value of awards which are expected to vest. The fair value of all share-based awards is estimated on the date of grant. |

| New Accounting Pronouncements, Policy [Policy Text Block] | New Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014 -09, Revenue from Contracts with Customers . This guidance is the culmination of the FASB’s joint project with the International Accounting Standards Board to clarify the principles for recognizing revenue. The core principal of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance provides a five -step process that entities should follow in order to achieve that core principal. ASU 2014 -09, as amended by ASU 2015 -14, Revenue from Contracts with Customers (Topic 606 ): Deferral of the Effective Date , ASU 2016 -08, Revenue from Contracts with Customers (Topic , ASU 606 ): Principal versus Agent Considerations2016 -10, Revenue from Contracts with Customers (Topic 606 ): Identifying Performance Obligations and Licensing, ASU 2016 -12, Revenue from Contracts with Customers (Topic 606 ): Narrow- Scope Improvements and Practical Expedients , and ASU 2016 -20, Technical Corrections and Improvements to Topic , becomes effective for the Company in 606, Revenue from Contracts with Customers2018. The guidance can be applied either on a full retrospective basis or on a modified retrospective basis in which the cumulative effect of initially applying the standard is recognized at the date of initial application. The Company has completed its assessment of the impacts the standard will have on its financial statements, and determined that the adoption does not have a material impact. In all material respects, the Company has identified a similar amount of performance obligations under the new guidance as compared with deliverables previously identified. As a result, the timing of revenue recognition will generally remain the same. The Company adopted the standard January 1, 2018 and will use the full retrospective method.In February 2016, the FASB issued ASU 2016 -02, Leases . This guidance is being issued to increase transparency and comparability among organizations by requiring the recognition of lease assets and lease liabilities on the balance sheet and by disclosing key information about leasing arrangements. The guidance should be applied using a modified retrospective approach and is effective for the Company in 2019, with early adoption permitted. The Company is currently assessing the impact the adoption of this guidance will have on the Company’s results of operations and financial position.In August 2016, the FASB issued ASU 2016 -15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments . This guidance is being issued to decrease diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This guidance should be applied on a retrospective basis and is effective for the Company in 2018, with early adoption permitted. The Company does not believe that the adoption of this guidance will have a significant impact on the presentation of the statement of cash flows. In January 2017, the FASB issued ASU 2017 -04, Intangibles – Goodwill and Other: Simplifying the Test for Goodwill Impairment . This guidance was issued to simplify the subsequent measurement of goodwill by eliminating Step 2 of the goodwill impairment test. Under the new guidance, the recognition of a goodwill impairment charge is calculated based on the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. This guidance should be applied on a prospective basis and is effective for the Company in 2020. The Company has early adopted this standard, which did not have a significant impact on its consolidated financial statements. In August 2017, the FASB issued ASU 2017 -12, Derivatives and Hedging – Targeted Improvements to Accounting for Hedging Activities . This guidance was issued to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements, and to make certain targeted improvements to simplify the application of the hedge accounting guidance. For existing hedges, this guidance should be applied using a cumulative effect adjustment, while the presentation and disclosure guidance should be adopted on a prospective basis. The standard is effective for the Company in 2019, with early adoption permitted. The Company is currently assessing the impact the adoption of this guidance will have on the Company’s results of operations and financial position.In the first quarter of 2017, the Company adopted ASU 2016 -09, Compensation – Stock Compensation: Improvements to Employee Share-Based Payment Accounting . The primary impact of adoption is the prospective recognition of excess tax benefits or deficiencies within the provision for income taxes on the consolidated statement of comprehensive income rather than within additional paid-in capital on the consolidated balance sheet. Further, the Company has elected to continue to estimate forfeitures expected to occur to determine the amount of stock compensation expense recognized each period. The Company also elected to apply the presentation requirements for cash flows related to excess tax benefits or deficiencies prospectively. The presentation requirements for cash flows related to employee taxes paid in exchange for withheld shares had no impact to any period presented on the consolidated statements of cash flows as such cash flows have historically been presented as a financing activity. There were no cumulative effect adjustments made to equity as of the beginning of the fiscal period, as those provisions of ASU 2016 -09 were not applicable or had no impact to the Company. There are several other new accounting pronouncements issued by the FASB. Each of these pronouncements, as applicable, has been or will be adopted by the Company. Management does not believe any of these accounting pronouncements has had or will have a material impact on the Company’s consolidated financial statements. |
