Basis of Presentation [Abstract]
Basis of Presentation	1. Basis of Presentation The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with the Securities and Exchange Commission (“SEC”) requirements for interim reporting, which allows certain footnotes and other financial information normally required by accounting principles generally accepted in the United States of America to be condensed or omitted. In our opinion, the Condensed Consolidated Financial Statements contain all adjustments (consisting of only normal recurring adjustments) necessary for the fair presentation of our financial position and results of operations. These statements should be read in conjunction with the Consolidated Financial Statements and Notes included in our annual report on Form 10-K for the year ended December 31, 2015 . The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year.

Restructuring and Related Activities [Abstract]
Management Actions	2. Management Actions During the third quarter of 2015, we implemented a restructuring action to reduce our infrastructure costs that we anticipated would improve Selling and Administrative Expense operating leverage in future quarters. The pre-tax charge of $1,779 recognized in the third quarter of 2015 consisted primarily of severance, the majority of which was in Europe, and was included within Selling and Administrative Expense in the Condensed Consolidated Statements of Earnings. We believe the anticipated savings will offset the pre-tax charge in approximately one year from the date of the action. The charge impacted our Americas, Europe, Middle East and Africa (EMEA) and Asia Pacific (APAC) operating segments. We do not expect additional costs will be incurred related to this restructuring action. During the fourth quarter of 2015, we implemented an additional restructuring action to reduce our infrastructure costs that we anticipated would improve Selling and Administrative Expense operating leverage in future quarters. The pre-tax charge of $1,965 , including other associated costs of $481 , consisted primarily of severance and was recorded in the fourth quarter of 2015. The pre-tax charge was included within Selling and Administrative Expense in the Condensed Consolidated Statements of Earnings. We believe the anticipated savings will offset the pre-tax charge in approximately 1.5 years from the date of the action. The charge impacted our Americas, EMEA and APAC operating segments. We do not expect additional costs will be incurred related to this restructuring action. A reconciliation of the beginning and ending liability balances is as follows: Severance and Related Costs 2015 restructuring actions $ 3,263 Cash payments (1,332 ) Foreign currency adjustments (19 ) December 31, 2015 balance $ 1,912 2016 utilization: Cash payments (468 ) Foreign currency adjustments 52 March 31, 2016 balance $ 1,496

Disposal Group, Not Discontinued Operation, Disposal Disclosures [Abstract]
Divestiture	Divestiture On August 19, 2015, we adopted a plan to sell assets and liabilities of the Green Machines TM outdoor city cleaning line as a result of determining that the product line, which constituted approximately two percent of our total sales, did not sufficiently complement our core business. Further details regarding the assets and liabilities held for sale as of December 31, 2015 are described in Note 6 of our annual report on Form 10-K for the year ended December 31, 2015 . On January 19, 2016 , we signed a Business Purchase Agreement (“BPA”) with Green Machines International GmbH and Green Machine Sweepers UK Limited, subsidiaries of M&F Management and Financing GmbH, which is also the parent company of the master distributor of our products in Central Eastern Europe, Middle East and Africa, TCS EMEA GmbH, for the sale of our Green Machines outdoor city cleaning line. Per the terms of the BPA, the sale closed on January 31, 2016 . Subject to working capital adjustments, the aggregate consideration for the Green Machines business is $5,700 . Under the BPA, the total aggregate consideration will be paid as follows: • Initial cash consideration of $285 , which was received during the first quarter of 2016. • An additional $1,015 to be paid within two weeks of finalization of the working capital adjustment. • The remaining purchase price of $4,400 , to be adjusted by the agreed upon closing working capital adjustment, will be financed and received in 13 equal installments on the last business day of each quarter, commencing with the quarter ending September 30, 2016 . As a result of this divestiture, we recorded a pre-tax loss of $62 in our Profit from Operations in the Condensed Consolidated Statements of Earnings. The impact of the recorded loss and the sale of Green Machines is not material to our earnings as Green Machines only accounted for approximately two percent of our total sales. Subsequent to the closing date, we will act as a distributor for Green Machine Sweepers UK Limited by continuing to sell Green Machines in certain regions, primarily the Americas and APAC, and will also serve as the exclusive service provider for Green Machines worldwide. Net of this estimated revenue, the divestiture is anticipated to reduce Tennant's annual revenue by approximately one percent, with an immaterial impact on earnings. We have identified Green Machines International GmbH as a variable interest entity (“VIE”) and have performed a qualitative assessment to determine if Tennant is the primary beneficiary of the VIE. We have determined that we are not the primary beneficiary of the VIE and consolidation of the VIE is not considered necessary.

Product Warranties Disclosures [Abstract]
Warranty	7. Warranty We record a liability for warranty claims at the time of sale. The amount of the liability is based on the trend in the historical ratio of claims to sales, the historical length of time between the sale and resulting warranty claim, new product introductions and other factors. Warranty terms on machines generally range from one to four years. However, the majority of our claims are paid out within the first six to nine months following a sale. The majority of the liability for estimated warranty claims represents amounts to be paid out in the near term for qualified warranty issues, with immaterial amounts reserved to be paid for older equipment warranty issues. The changes in warranty reserves for the three months ended March 31, 2016 and 2015 were as follows: Three Months Ended March 31 2016 2015 Beginning balance $ 10,093 $ 9,686 Additions charged to expense 2,488 2,413 Foreign currency fluctuations 60 (167 ) Claims paid (2,766 ) (2,498 ) Ending balance $ 9,875 $ 9,434

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	8. Derivatives Hedge Accounting and Hedging Programs We recognize all derivative instruments as either assets or liabilities in our Condensed Consolidated Balance Sheets and measure them at fair value. Gains and losses resulting from changes in fair value are accounted for depending on the use of the derivative and whether it is designated and qualifies for hedge accounting. We evaluate hedge effectiveness on our hedges that are designated and qualify for hedge accounting at the inception of the hedge prospectively, as well as retrospectively, and record any ineffective portion of the hedging instruments in Net Foreign Currency Transaction Losses in our Condensed Consolidated Statements of Earnings. The time value of purchased contracts is recorded in Net Foreign Currency Transaction Losses in our Condensed Consolidated Statements of Earnings. Balance Sheet Hedging – Hedges of Foreign Currency Assets and Liabilities We hedge our net recognized foreign currency denominated assets and liabilities with foreign exchange forward contracts to reduce the risk that the value of these assets and liabilities will be adversely affected by changes in exchange rates. These contracts hedge assets and liabilities that are denominated in foreign currencies and are carried at fair value as either assets or liabilities on the Condensed Consolidated Balance Sheets with changes in the fair value recorded to Net Foreign Currency Transaction Losses in our Condensed Consolidated Statements of Earnings. These contracts do not subject us to material balance sheet risk due to exchange rate movements because gains and losses on these derivatives are intended to offset gains and losses on the assets and liabilities being hedged. At March 31, 2016 and December 31, 2015 , the notional amounts of foreign currency forward exchange contracts outstanding not designated as hedging instruments were $46,515 and $45,851 , respectively. Cash Flow Hedging – Hedges of Forecasted Foreign Currency Transactions In countries outside the U.S., we transact business in U.S. dollars and in various other currencies. We may use foreign exchange option contracts or forward contracts to hedge certain cash flow exposures resulting from changes in these foreign currency exchange rates. These foreign exchange contracts, carried at fair value, have maturities of up to one year . We enter into these foreign exchange contracts to hedge a portion of our forecasted foreign currency denominated revenue in the normal course of business, and accordingly, they are not speculative in nature. The notional amounts of outstanding foreign currency forward contracts designated as cash flow hedges were $2,631 and $2,486 as of March 31, 2016 and December 31, 2015 , respectively. The notional amounts of outstanding foreign currency option contracts designated as cash flow hedges were $9,137 and $11,271 as of March 31, 2016 and December 31, 2015 , respectively. To receive hedge accounting treatment, all hedging relationships are formally documented at the inception of the hedge, and the hedges must be highly effective in offsetting changes to future cash flows on hedged transactions. We record changes in the fair value of these cash flow hedges in Accumulated Other Comprehensive Loss in our Condensed Consolidated Balance Sheets, until the forecasted transaction occurs. When the forecasted transaction occurs, we reclassify the related gain or loss on the cash flow hedge to Net Sales in our Condensed Consolidated Statements of Earnings. In the event the hedge becomes ineffective, the underlying forecasted transaction does not occur, or it becomes probable that it will not occur, we reclassify the gain or loss on the related cash flow hedge from Accumulated Other Comprehensive Loss to Net Foreign Currency Transaction Losses in our Condensed Consolidated Statements of Earnings at that time. If we do not elect hedge accounting, or the contract does not qualify for hedge accounting treatment, the changes in fair value from period to period are recorded in Net Foreign Currency Transaction Losses in our Condensed Consolidated Statements of Earnings. The fair value of derivative instruments on our Condensed Consolidated Balance Sheets as of March 31, 2016 and December 31, 2015 were as follows: March 31, 2016 December 31, 2015 Fair Value Asset Derivatives Fair Value Liability Derivatives Fair Value Asset Derivatives Fair Value Liability Derivatives Derivatives designated as hedging instruments: Foreign currency option contracts (1)(2) $ 109 $ — $ 387 $ — Foreign currency forward contracts (1) — 35 113 — Derivatives not designated as hedging instruments: Foreign currency forward contracts (1) $ 28 $ 1,354 $ 171 $ 7 (1) Contracts that mature within the next 12 months are included in Other Current Assets and Other Current Liabilities for asset derivatives and liabilities derivatives, respectively, on our Condensed Consolidated Balance Sheets. (2) Contracts with a maturity greater than 12 months are included in Other Assets and Other Liabilities for asset derivatives and liability derivatives, respectively, on our Condensed Consolidated Balance Sheets. As of March 31, 2016 , we anticipate reclassifying approximately $215 of losses from Accumulated Other Comprehensive Loss to net earnings during the next 12 months.

Fair Value Measurements Estimates of fair value for financial assets and financial liabilities are based on the framework established in the accounting guidance for fair value measurements. The framework defines fair value, provides guidance for measuring fair value and requires certain disclosures. The framework discusses valuation techniques, such as the market approach (comparable market prices), the income approach (present value of future income or cash flow) and the cost approach (cost to replace the service capacity of an asset or replacement cost). The framework utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels: • Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities. • Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. • Level 3: Unobservable inputs that reflect the reporting entity’s own assumptions. Our population of assets and liabilities subject to fair value measurements at March 31, 2016 is as follows: Fair Value Level 1 Level 2 Level 3 Assets: Foreign currency forward exchange contracts $ 28 $ — $ 28 $ — Foreign currency option contracts 109 — 109 — Total Assets $ 137 $ — $ 137 $ — Liabilities: Foreign currency forward exchange contracts $ 1,389 $ — $ 1,389 $ — Total Liabilities $ 1,389 $ — $ 1,389 $ — Our foreign currency forward and option exchange contracts are valued using observable Level 2 market expectations at the measurement date and standard valuation techniques to convert future amounts to a single present value amount. Further details regarding our foreign currency forward exchange and option contracts are discussed in Note 8. The carrying amounts reported in the Condensed Consolidated Balance Sheets for Cash and Cash Equivalents, Restricted Cash, Accounts Receivable, Other Current Assets, Accounts Payable and Other Current Liabilities approximate fair value due to their short-term nature. The fair value of our Long-Term Debt approximates cost based on the borrowing rates currently available to us for bank loans with similar terms and remaining maturities. From time to time, we measure certain assets at fair value on a non-recurring basis, including evaluation of long-lived assets, goodwill and other intangible assets for impairment using company-specific assumptions that would fall within Level 3 of the fair value hierarchy.

Commitments Contingencies and Guarantees [Text Block]	11. Commitments and Contingencies Certain operating leases for vehicles contain residual value guarantee provisions, which would become due at the expiration of the operating lease agreement if the fair value of the leased vehicles is less than the guaranteed residual value. As of March 31, 2016 , of those leases that contain residual value guarantees, the aggregate residual value at lease expiration was $11,986 , of which we have guaranteed $9,681 . As of March 31, 2016 , we have recorded a liability for the estimated end of term loss related to this residual value guarantee of $404 for certain vehicles within our fleet. Our fleet also contains vehicles we estimate will settle at a gain. Gains on these vehicles will be recognized at the end of the lease term. During the first quarter of 2016 , we entered into a distributor agreement with Green Machine Sweepers UK Limited, an affiliate of Green Machines International GmbH, for the exclusive right for Tennant to distribute, market, sell, rent and lease Green Machines products, aftermarket parts and consumables in the Americas and APAC. As part of this distributor agreement, we entered into a purchase commitment obligating us to purchase $12,000 of products and aftermarket parts and consumables annually for the next two years , for a total purchase commitment of $24,000 . On March 23, 2016, we entered into a four year Joint Development Agreement with a partner to develop software. As part of that agreement we have committed to spend $3,000 during the first year of the agreement and $8,000 over the life of the agreement, subject to regular time and materials billing and achievement of contract milestones.

Income Tax Disclosure [Abstract]
Income Taxes	13. Income Taxes We and our subsidiaries are subject to U.S. federal income tax as well as income tax of numerous state and foreign jurisdictions. We are generally no longer subject to U.S. federal tax examinations for taxable years before 2012 and, with limited exceptions, state and foreign income tax examinations for taxable years before 2007 . We recognize potential accrued interest and penalties related to unrecognized tax benefits in Income Tax Expense. In addition to the liability of $2,534 for unrecognized tax benefits as of March 31, 2016 , there was approximately $528 for accrued interest and penalties. The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate as of March 31, 2016 was $2,177 . To the extent interest and penalties are not assessed with respect to uncertain tax positions, amounts accrued will be revised and reflected as an adjustment of the Income Tax Expense. We are currently undergoing income tax examinations in various state and foreign jurisdictions covering 2007 to 2014 . Although the final outcome of these examinations cannot be currently determined, we believe that we have adequate reserves with respect to these examinations.
