New Accounting Standards [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Standards
	In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360), Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. This update revises the required criteria for reporting disposals as discontinued operations, whereby discontinued operations are limited to disposals that represent strategic shifts that had (or will have) a major effect on an entity's operations and financial results. The Company will be required to adopt ASU No. 2014-08 as of October 1, 2015. The Company does not expect the adoption of ASU 2014-08 to have a material impact on its financial statements.
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which clarifies the principles for recognizing revenue. This guidance requires an entity to 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 Company will be required to adopt ASU No. 2014-09 as of October 1, 2017. The Company is currently evaluating the impact of ASU No. 2014-09 on the Company’s financial condition, results of operations and cash flows.
	In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements (Topic 205) Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. The guidance requires management to perform an evaluation each annual and interim reporting period of whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within the one year period after the date that the financial statements are issued. If such conditions are identified, the guidance requires an entity to provide certain disclosures about the principal conditions or events that gave rise to the substantial doubt about the entity’s ability to continue as a going concern, management’s evaluation of the significance of those conditions or events in relation to the entity’s ability to meet its obligations and management’s plans to alleviate or mitigate substantial doubt about the entity’s ability to continue as a going concern. The Company will be required to adopt ASU No. 2014-15 as of October 1, 2016. The Company does not expect the adoption of ASU 2014-15 to have a material impact on its financial statements.
	In February 2015, the FASB issued ASU No. 2015-02, Consolidation (Topic 810), Amendments to the Consolidation Analysis, which amends the guidance that reporting entities apply when evaluating whether certain legal entities should be consolidated. The Company will be required to adopt ASU No. 2015-02 as of October 1, 2016. The Company does not expect the adoption of ASU 2015-02 to have a material impact on the Company's financial statements.
	In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Topic 835-30), Simplifying the Presentation of Debt Issuance Costs. ASU No. 2015-03 is part of the FASB’s initiative to reduce complexity in accounting standards. The guidance requires an entity to recognize debt issuance costs related to a debt liability as a direct deduction from the carrying amount of the debt liability in the balance sheet, thereby increasing the effective rate of interest, as opposed to a deferred cost. The Company will be required to adopt ASU No. 2015-03 as of October 1, 2016. The Company is currently evaluating the impact of ASU No. 2015-03 on the Company’s financial statements.

	Receivables consisted of the following (in millions):
		March 31,			September 30,
		2015			2014
	U.S. government:
	Amounts billed	$	28.6		$	80.4
	Costs and profits not billed	20.1			21.3

	Less allowance for doubtful accounts	(21.2		)	(21.8		)
		$	1,013.00		$	990.4
	Costs and profits not billed include undefinitized change orders on existing long-term contracts and “not-to-exceed” undefinitized contracts whereby the Company cannot invoice the customer the full price under the contract or contract change order until such contract or change order is definitized and agreed to with the customer following a review of costs under such contract or change order, even though the contract deliverables may have been met. Definitization of a change order on an existing long-term contract or a sole source contract begins when the U.S. government customer undertakes a detailed review of the Company’s submitted costs and proposed margin related to the contract and concludes with a final change order. The Company recognizes revenue on undefinitized contracts to the extent that it can reasonably and reliably estimate the expected final contract price and when collectability is reasonably assured. To the extent that contract definitization results in changes to previously estimated or incurred costs or revenues, the Company records those adjustments as a change in estimate. During the six months ended March 31, 2014, the Company recorded revenue of $7.5 million related to changes in estimates on undefinitized contracts. The change increased net income by $4.7 million, or $0.05 per share, for the six months ended March 31, 2014.

	Allowance for doubtful accounts	—			—			(12.1		)	(13.6		)
	Finance Receivables: Finance receivables represent sales-type leases resulting from the sale of the Company's products and the purchase of finance receivables from lenders pursuant to customer defaults under program agreements with finance companies. Finance receivables originated by the Company generally include a residual value component. Residual values are determined based on the expectation that the underlying equipment will have a minimum fair market value at the end of the lease term. This residual value accrues to the Company at the end of the lease. The Company uses its experience and knowledge as an original equipment manufacturer and participant in end markets for the related products along with third-party studies to estimate residual values. The Company monitors these values for impairment on a periodic basis and reflects any resulting reductions in value in current earnings. Finance receivables are written down if management determines that the specific borrower does not have the ability to repay the loan amounts due in full.
	Delinquency is the primary indicator of credit quality of finance receivables. The Company maintains a general allowance for finance receivables considered doubtful of future collection based upon historical experience. Additional allowances are established based upon the Company’s perception of the quality of the finance receivables, including the length of time the receivables are past due, past experience of collectability and underlying economic conditions. In circumstances where the Company believes collectability is no longer reasonably assured, a specific allowance is recorded to reduce the net recognized receivable to the amount reasonably expected to be collected. The terms of the finance agreements generally give the Company the ability to take possession of the underlying collateral. The Company may incur losses in excess of recorded allowances if the financial condition of its customers were to deteriorate or the full amount of any anticipated proceeds from the sale of the collateral supporting its customers’ financial obligations is not realized.
	Notes Receivable: Notes receivable include amounts related to refinancing of trade accounts and finance receivables. As of March 31, 2015, approximately 73% of the notes receivable balance outstanding was due from two parties. The Company routinely evaluates the creditworthiness of its customers and establishes reserves where the Company believes collectability is no longer reasonably assured. Notes receivable are written down if management determines that the specific borrower does not have the ability to repay the loan in full. Certain notes receivable are collateralized by a security interest in the underlying assets and/or other assets owned by the debtor. The Company may incur losses in excess of recorded allowances if the financial condition of its customers were to deteriorate or the full amount of any anticipated proceeds from the sale of the collateral supporting its customers' financial obligations is not realized.
	Quality of Finance and Notes Receivable: The Company does not accrue interest income on finance and notes receivable in circumstances where the Company believes collectability is no longer reasonably assured. Any cash payments received on nonaccrual finance and notes receivable are applied first to the principal balances. The Company does not resume accrual of interest income until the customer has shown that it is capable of meeting its financial obligations by making timely payments over a sustained period of time. The Company determines past due or delinquency status based upon the due date of the receivable.
	Receivables subject to specific reserves also include loans that the Company has modified in troubled debt restructurings as a concession to customers experiencing financial difficulty. To minimize the economic loss, the Company may modify certain finance and notes receivable. Modifications generally consist of restructured payment terms and time frames in which no payments are required. At March 31, 2015, restructured finance and notes receivables were $0.6 million and $15.5 million, respectively. Losses on troubled debt restructurings were not significant during the three and six months ended March 31, 2015 and 2014, respectively. The Company agreed to restructure a note receivable with a customer in December 2014. Under the terms of the restructured note, the maturity date was changed from June 30, 2017 to December 31, 2019. The restructured note requires the customer to make semi-annual payments of principal and interest with a balloon payment due at maturity, consistent with the previous note. At March 31, 2015, the outstanding balance of the restructured note, net of reserves, was $3.4 million.

The Company recognized sales to Mezcladoras of $6.3 million and $3.6 million during the six months ended March 31, 2015 and 2014, respectively. The Company recognizes income on sales to Mezcladoras at the time of shipment in proportion to the outside third-party interest in Mezcladoras and recognizes the remaining income upon the joint venture's sale of inventory to an unaffiliated customer. The Company earns a service fee for certain operational support services provided to Mezcladoras. For the six months ended March 31, 2015 and 2014, the Company recognized service fees of $0.6 million and $0.4 million, respectively.
	The Company and an unaffiliated third party are joint venture partners in RiRent Europe BV ("RiRent"). RiRent maintains a fleet of access equipment for short-term lease to rental companies throughout most of Europe. The re-rental fleet provides rental companies with equipment to support requirements on short notice. RiRent does not provide services directly to end users. The Company and its joint venture partner are in the process of winding down RiRent. The last sale of new equipment to RiRent by the Company was in October 2013. To the extent that RiRent has existing outstanding contracts, those contracts will continue to be maintained. The Company received a dividend of €2.25 million ($2.8 million)from RiRent in December 2014. Indebtedness of RiRent is secured by the underlying leases and assets of RiRent. All such RiRent indebtedness is non-recourse to the Company and its partner. Under RiRent’s €2.0 million bank credit facility, the partners of RiRent have committed that RiRent will maintain an overall equity to asset ratio of at least 30.0% (RiRent's equity to asset ratio was 98.7% as of March 31, 2015).

	On March 21, 2014, the Company entered into an Amended and Restated Credit Agreement with various lenders (the “Credit Agreement”). The Credit Agreement provides for (i) a revolving credit facility (“Revolving Credit Facility”) that matures in March 2019 with an initial maximum aggregate amount of availability of $600 million and (ii) a $400 million term loan (“Term Loan”) due in quarterly principal installments of $5.0 million with a balloon payment of $310.0 million due at maturity in March 2019. On January 22, 2015, the Company entered into an agreement with lenders under the Credit Agreement that increased the Revolving Credit Facility to an aggregate maximum amount of $850 million effective January 26, 2015. At March 31, 2015, borrowings under the Revolving Credit Facility of $13.7 million and outstanding letters of credit of $75.9 million reduced available capacity under the Revolving Credit Facility to $760.4 million.
	The Company’s obligations under the Credit Agreement are guaranteed by certain of its domestic subsidiaries, and the Company will guarantee the obligations of certain of its subsidiaries under the Credit Agreement. Subject to certain exceptions, the Credit Agreement is collateralized by (i) a first-priority perfected lien and security interests in substantially all of the personal property of the Company, each material subsidiary of the Company and each subsidiary guarantor, (ii) mortgages upon certain real property of the Company and certain of its domestic subsidiaries and (iii) a pledge of the equity of each material subsidiary of the Company.
	Under the Credit Agreement, the Company must pay (i) an unused commitment fee ranging from 0.225% to 0.35% per annum of the average daily unused portion of the aggregate revolving credit commitments under the Credit Agreement and (ii) a fee ranging from 0.625% to 2.00% per annum of the maximum amount available to be drawn for each letter of credit issued and outstanding under the Credit Agreement.
	Borrowings under the Credit Agreement bear interest at a variable rate equal to (i) LIBOR plus a specified margin, which may be adjusted upward or downward depending on whether certain criteria are satisfied, or (ii) for dollar-denominated loans only, the base rate (which is the highest of (a) the administrative agent’s prime rate, (b) the federal funds rate plus 0.50% or (c) the sum of 1% plus one-month LIBOR) plus a specified margin, which may be adjusted upward or downward depending on whether certain criteria are satisfied. At March 31, 2015, the interest spread on the Revolving Credit Facility and Term Loan was 150 basis points. The interest rate on the borrowings outstanding under the Revolving Credit Facility at March 31, 2015 was 1.68%. The weighted-average interest rate on borrowings outstanding under the Term Loan at March 31, 2015 was 1.67%.
	The Credit Agreement contains various restrictions and covenants, including requirements that the Company maintain certain financial ratios at prescribed levels and restrictions, subject to certain exceptions, on the ability of the Company and certain of its subsidiaries to consolidate or merge, create liens, incur additional indebtedness, dispose of assets, consummate acquisitions and make investments in joint ventures and foreign subsidiaries.
	The Credit Agreement contains the following financial covenants:
	•	Leverage Ratio: A maximum leverage ratio (defined as, with certain adjustments, the ratio of the Company’s consolidated indebtedness to consolidated net income before interest, taxes, depreciation, amortization, non-cash charges and certain other items (“EBITDA”)) as of the last day of any fiscal quarter of 4.50 to 1.00.
	•	Interest Coverage Ratio: A minimum interest coverage ratio (defined as, with certain adjustments, the ratio of the Company’s consolidated EBITDA to the Company’s consolidated cash interest expense) as of the last day of any fiscal quarter of 2.50 to 1.00.
	•	Senior Secured Leverage Ratio: A maximum senior secured leverage ratio (defined as, with certain adjustments, the ratio of the Company’s consolidated secured indebtedness to the Company’s consolidated EBITDA) of 3.00 to 1.00.
	With certain exceptions, the Company may elect to have the collateral pledged in connection with the Credit Agreement released during any period that the Company maintains an investment grade corporate family rating from either Standard & Poor’s Ratings Group or Moody’s Investor Service Inc. During any such period when the collateral has been released, the Company’s leverage ratio as of the last day of any fiscal quarter must not be greater than 3.75 to 1.00, and the Company would not be subject to any additional requirement to limit its senior secured leverage ratio.
	The Company was in compliance with the financial covenants contained in the Credit Agreement as of March 31, 2015.
	Additionally, with certain exceptions, the Credit Agreement limits the ability of the Company to pay dividends and other distributions, including repurchases of shares of its Common Stock. However, so long as no event of default exists under the Credit Agreement or would result from such payment, the Company may pay dividends and other distributions after March 3, 2010 in an aggregate amount not exceeding the sum of:
	i.	50% of the consolidated net income of the Company and its subsidiaries (or if such consolidated net income is a deficit, minus 100% of such deficit), accrued on a cumulative basis during the period beginning on January 1, 2010 and ending on the last day of the fiscal quarter immediately preceding the date of the applicable proposed dividend or distribution; and
	ii.	100% of the aggregate net proceeds received by the Company subsequent to March 3, 2010 either as a contribution to its common equity capital or from the issuance and sale of its Common Stock.
	In March 2010, the Company issued $250.0 million of 8¼% unsecured senior notes due March 1, 2017 (the “2017 Senior Notes”) and $250.0 million of 8½% unsecured senior notes due March 1, 2020 (the “2020 Senior Notes”). On February 21, 2014, the Company issued $250.0 million of 5.375% unsecured senior notes due March 1, 2022 (the “2022 Senior Notes”). The Company used the net proceeds from the sale of the 2022 Senior Notes, together with available cash, to redeem all of the outstanding 2017 Senior Notes at a price of 104.125%. On March 2, 2015, the Company issued $250.0 million of 5.375% unsecured senior notes due March 1, 2025 (the “2025 Senior Notes”). The Company used the net proceeds from the sale of the 2025 Senior Notes, together with available cash, to redeem all of the outstanding 2020 Senior Notes at a price of 104.250%. The Company recognized approximately $14.7 million of expense associated with the 2025 Senior Notes transaction, comprised of unamortized debt issuance costs, call premium and third-party costs. Expenses related to the transaction are included in interest expense. Additionally, approximately $3.5 million of debt issuance costs were capitalized to prepaid assets in connection with the transaction. The Company has the option to redeem the 2022 Senior Notes and the 2025 Senior Notes for a premium after March 1, 2017 and March 1, 2020, respectively.
	The 2022 Senior Notes and the 2025 Senior Notes were issued pursuant to separate indentures (the “Indentures”) among the Company, the subsidiary guarantors named therein and a trustee. The Indentures contain customary affirmative and negative covenants. Certain of the Company’s subsidiaries jointly, severally, fully and unconditionally guarantee the Company’s obligations under the 2022 Senior Notes and 2025 Senior Notes. See Note 21 of the Notes to Condensed Consolidated Financial Statements for separate financial information of the subsidiary guarantors.
	The fair value of the long-term debt is estimated based upon Level 2 inputs to reflect market rate of the Company’s debt. At March 31, 2015, the fair value of the 2022 Senior Notes and the 2025 Senior Notes was estimated to be $259 million and $258 million, respectively, and the fair value of the Term Loan approximated book value. See Note 13 of the Notes to Condensed Consolidated Financial Statements for the definition of a Level 2 input.

Warranties	Warranties
	The Company’s products generally carry explicit warranties that extend from six months to five years, based on terms that are generally accepted in the marketplace. Selected components (such as engines, transmissions, tires, etc.) included in the Company’s end products may include manufacturers’ warranties. These manufacturers’ warranties are generally passed on to the end customer of the Company’s products, and the customer would generally deal directly with the component manufacturer.
	Changes in the Company’s warranty liability were as follows (in millions):
		Six Months Ended

	Foreign currency translation	(1.6		)	0.2
	Balance at end of period	$	81.4		$	94.3
	Provisions for estimated warranty and other related costs are recorded at the time of sale and are periodically adjusted to reflect actual experience. Certain warranty and other related claims involve matters of dispute that ultimately are resolved by negotiation, arbitration or litigation. At times, warranty issues arise that are beyond the scope of the Company's historical experience. It is reasonably possible that additional warranty and other related claims could arise from disputes or other matters in excess of amounts accrued; however, the Company does not expect that any such amounts, while not determinable, would have a material adverse effect on the Company's consolidated financial condition, result of operations or cash flows. Accrued warranty expense as a percent of prior 12 months sales declined slightly from 1.32% at September 30, 2013 to 1.25% at March 31, 2015, generally due to favorable claims experience in the Company's non-defense segments.

Guarantees [Abstract]
Guarantee Arrangements	Guarantee Arrangements
	The Company is party to multiple agreements whereby at March 31, 2015 it guaranteed an aggregate of $469.6 million in indebtedness of customers. The Company estimated that its maximum loss exposure under these agreements at March 31, 2015 was $123.2 million. Under the terms of these and various related agreements and upon the occurrence of certain events, the Company generally has the ability to, among other things, take possession of the underlying collateral. If the financial condition of the customers were to deteriorate and result in their inability to make payments, then additional accruals may be required. While the Company does not expect to experience losses under these agreements that are materially in excess of the amounts reserved, it cannot provide any assurance that the financial condition of the customers will not deteriorate resulting in the customers' inability to meet their obligations. In the event that this occurs, the Company cannot guarantee that the collateral underlying the agreements will be sufficient to avoid losses materially in excess of the amounts reserved. Any losses under these guarantees would generally be mitigated by the value of any underlying collateral, including financed equipment, and are generally subject to the finance company's ability to provide the Company clear title to foreclosed equipment and other conditions. During periods of economic weakness, collateral values generally decline and can contribute to higher exposure to losses.

Derivative Financial Instruments and Hedging Activities

Derivative Financial Instruments and Hedging Activities

The Company has used forward foreign currency exchange contracts (“derivatives”) to reduce the exchange rate risk of specific foreign currency denominated transactions. These derivatives typically require the exchange of a foreign currency for U.S. dollars at a fixed rate at a future date. At times, the Company has designated these hedges as either cash flow hedges or fair value hedges under FASB Accounting Standards Codification ("ASC") Topic 815, Derivatives and Hedging. At March 31, 2015, the total notional U.S. dollar equivalent of outstanding forward foreign exchange contracts designated as hedges in accordance with ASC Topic 815 was $0.6 million. Net gains or losses related to hedge ineffectiveness were insignificant for the six month periods ended March 31, 2015 and 2014. Ineffectiveness is included in "Miscellaneous, net" in the Condensed Consolidated Statements of Income along with mark-to-market adjustments on outstanding non-designated derivatives.

The Company has entered into forward foreign currency exchange contracts to create an economic hedge to manage foreign exchange risk exposure associated with non-functional currency denominated payables resulting from global sourcing activities. The Company has not designated these derivative contracts as hedge transactions under FASB ASC Topic 815, and accordingly, the mark-to-market impact of these derivatives is recorded each period in current earnings. The fair value of foreign currency related derivatives is included in the Condensed Consolidated Balance Sheets in “Other current assets” and “Other current liabilities.” At March 31, 2015, the U.S. dollar equivalent of these outstanding forward foreign exchange contracts totaled $101.7 million in notional amounts, including $25.1 million in contracts to sell euro, $42.5 million in contracts to sell Australian dollars, $17.1 million in contracts to buy U.K. pound sterling, $8.1 million in contracts to buy Swedish krona and sell euro and $6.2 million in contracts to buy euro and sell Canadian dollars, with the remaining contracts covering a variety of foreign currencies.

Fair Value Disclosures [Abstract]
Fair Value Measurement	Fair Value Measurement
	FASB ASC Topic 820, Fair Value Measurements and Disclosures, defines fair value as the price that would be received to sell an asset or paid to transfer a liability (i.e., exit price) in an orderly transaction between market participants at the measurement date. FASB ASC Topic 820 requires disclosures that categorize assets and liabilities measured at fair value into one of three different levels depending on the assumptions (i.e., inputs) used in the valuation. Level 1 provides the most reliable measure of fair value, while Level 3 generally requires significant management judgment.
	The three levels are defined as follows:
	Level 1:	Unadjusted quoted prices in active markets for identical assets or liabilities.
	Level 2:	Observable inputs other than quoted prices in active markets for identical assets or liabilities, such as quoted prices for similar assets or liabilities in active markets or quoted prices for identical assets or liabilities in inactive markets.
	Level 3:	Unobservable inputs reflecting management's own assumptions about the inputs used in pricing the asset or liability.
	There were no transfers of assets between levels during the three and six months ended March 31, 2015.
	As of March 31, 2015, the fair values of the Company’s financial assets and liabilities were as follows (in millions):

	In February 2009, the Company’s shareholders approved the 2009 Incentive Stock and Awards Plan (as amended, the “2009 Stock Plan”). The 2009 Stock Plan replaced the 2004 Incentive Stock and Awards Plan (as amended, the “2004 Stock Plan”). While no new awards will be granted under the 2004 Stock Plan, awards previously made under the 2004 Stock Plan that were outstanding as of the initial approval date of the 2009 Stock Plan will remain outstanding and continue to be governed by the provisions of the 2004 Stock Plan. At March 31, 2015, the Company had reserved 6,947,590 shares of Common Stock available for issuance under the 2009 Stock Plan to provide for the exercise of outstanding stock options and the issuance of Common Stock under incentive compensation awards, including awards issued prior to the effective date of the 2009 Stock Plan.
	The Company recognizes stock-based compensation expense over the requisite service period for vesting of an award, or to an employee's eligible retirement date, if earlier and applicable. Total stock-based compensation expense, including cash-based liability awards, included in the Condensed Consolidated Statements of Income for the three and six months ended March 31, 2015 was $6.8 million ($4.3 million net of tax) and $13.3 million ($8.4 million net of tax), respectively. Total stock-based compensation expense, including cash-based liability awards, included in the Condensed Consolidated Statements of Income for the three and six months ended March 31, 2014 was $10.1 million ($6.4 million net of tax) and $16.0 million ($10.1 million net of tax), respectively.

	The Company's effective income tax rate was 35.7% and 24.6% of pre-tax income for the three months ended March 31, 2015 and 2014, respectively. Tax expense included net discrete tax benefits of 50 basis points and 1,120 basis points for the three months ended March 31, 2015 and 2014, respectively. Discrete tax benefits recorded in the three months ended March 31, 2014 included a reduction of a valuation allowance on net operating loss and deferred interest carryforwards following receipt of a favorable tax ruling from tax authorities in March 2014 totaling 1,300 basis points, partially offset by a provision for a state tax audit settlement totaling 180 basis points.
	The Company's effective income tax rate was 34.2% and 27.6% of pre-tax income for the six months ended March 31, 2015 and 2014, respectively. Tax expense included net discrete tax benefits of 80 basis points and 710 basis points for the six months ended March 31, 2015 and 2014, respectively. Discrete tax benefits recorded in the six months ended March 31, 2015 included a 160 basis point benefit resulting from the December 2014 reinstatement of the U.S. research and development tax credit and net other discrete charges aggregating 80 basis points. Discrete tax benefits recorded in the six months ended March 31, 2014 included the benefit of a reduction of a valuation allowance on net operating loss and deferred interest carryforwards noted above totaling 700 basis points. Discrete tax charges related to a provision for a state tax audit settlement totaling 100 basis points were offset by net other discrete tax benefits aggregating 100 basis points.
	The Company’s liability for gross unrecognized tax benefits, excluding related interest and penalties, was $41.4 million and $32.8 million as of March 31, 2015 and September 30, 2014, respectively. As of March 31, 2015, net unrecognized tax benefits, excluding interest and penalties, of $23.7 million would affect the Company’s net income if recognized.
	The Company recognizes accrued interest and penalties, if any, related to unrecognized tax benefits in the “Provision for income taxes” in the Condensed Consolidated Statements of Income. During the six months ended March 31, 2015 and 2014, the Company recognized charges of $1.5 million and $1.7 million, respectively, related to interest and penalties. At March 31, 2015, the Company had accruals for the payment of interest and penalties of $19.0 million. During the next twelve months, it is reasonably possible that federal, state and foreign tax audit resolutions could reduce net unrecognized tax benefits by approximately $15.5 million because the Company’s tax positions are sustained on audit, the Company agrees to their disallowance or the applicable statutes of limitations expire.
	The Company files federal income tax returns as well as multiple state, local and non-U.S. jurisdiction tax returns. The Company is regularly audited by federal, state and foreign tax authorities.

Earnings Per Share [Abstract]
Earnings Per Share [Text Block]	Earnings Per Share
	Prior to September 1, 2013, the Company granted awards of nonvested stock that contained a nonforfeitable right to dividends, if declared. In accordance with FASB ASC Topic 260, Earnings Per Share, these awards are considered to be participating securities, and as a result, earnings per share is calculated using the two-class method. The two-class method is an earnings allocation method that determines earnings per share for common shares and participating securities. The undistributed earnings are allocated between common shares and participating securities as if all earnings had been distributed during the period. Participating securities and common shares have equal rights to undistributed earnings.
	Effective September 1, 2013, new grants of awards of nonvested stock do not contain a nonforfeitable right to dividends during the vesting period. As a result, an employee will forfeit the right to dividends accrued on unvested awards if such awards do not ultimately vest. As such, these awards are not treated as participating securities in the earnings per share calculation as the employees do not have equivalent dividend rights as common shareholders.
	The calculation of basic and diluted earnings per common share was as follows (in millions, except number of share amounts):

	Personal Injury Actions and Other - Product and general liability claims are made against the Company from time to time in the ordinary course of business. The Company is generally self-insured for future claims up to $5.0 million per claim. Accordingly, a reserve is maintained for the estimated costs of such claims. At March 31, 2015 and September 30, 2014, the estimated net liabilities for product and general liability claims totaled $39.9 million and $39.4 million, respectively. There is inherent uncertainty as to the eventual resolution of unsettled claims. Management, however, believes that any losses in excess of established reserves will not have a material adverse effect on the Company’s financial condition, results of operations or cash flows.
	Market Risks - The Company was contingently liable under bid, performance and specialty bonds totaling $375.5 million and open standby letters of credit issued by the Company’s banks in favor of third parties totaling $75.9 million at March 31, 2015.
	Other Matters - The Company is subject to environmental matters and legal proceedings and claims, including patent, antitrust, product liability, warranty and state dealership regulation compliance proceedings, that arise in the ordinary course of business. Although the final results of all such matters and claims cannot be predicted with certainty, management believes that the ultimate resolution of all such matters and claims will not have a material adverse effect on the Company’s financial condition, results of operations or cash flows. Actual results could vary due to, among other things, the uncertainties involved in litigation.
	Major contracts for military systems are performed over extended periods of time and are subject to changes in scope of work and delivery schedules. Pricing negotiations on changes and settlement of claims often extend over prolonged periods of time. The Company’s ultimate profitability on such contracts may depend on the eventual outcome of an equitable settlement of contractual issues with the Company’s customers.

Segment Reporting [Abstract]
Business Segment Information	Business Segment Information
	The Company is organized into four reportable segments based on the internal organization used by management for making operating decisions and measuring performance and based on the similarity of customers served, common management, common use of facilities and economic results attained.
	In accordance with FASB ASC Topic 280, Segment Reporting, for purposes of business segment performance measurement, the Company does not allocate to individual business segments costs or items that are of a non-operating nature or organizational or functional expenses of a corporate nature. The caption “Corporate” includes corporate office expenses, share-based compensation, costs of certain business initiatives and shared services benefiting multiple segments, and results of insignificant operations. Identifiable assets of the business segments exclude general corporate assets, which principally consist of cash and cash equivalents, certain property, plant and equipment, and certain other assets pertaining to corporate activities. Intersegment sales generally include amounts invoiced by a segment for work performed for another segment. Amounts are based on actual work performed and agreed-upon pricing, which is intended to be reflective of the contribution made by the supplying business segment.

	The 2022 Senior Notes and the 2025 Senior Notes are jointly, severally, fully and unconditionally guaranteed on a senior unsecured basis by all of the Company’s 100% owned existing and future subsidiaries that from time to time guarantee obligations under the Credit Agreement, with certain exceptions (the “Guarantors”).
	On June 30, 2014, the Company completed a holding company reorganization pursuant to which Oshkosh became the parent holding company for the Company's entire group of businesses, including the Company's defense business, which prior to the reorganization, Oshkosh operated directly. As part of the reorganization, Oshkosh formed a new, wholly-owned subsidiary, Oshkosh Defense, LLC ("Oshkosh Defense"), and Oshkosh Defense succeeded to the Company's defense business. As a result, Oshkosh Defense became a Guarantor of Oshkosh's obligations under the Credit Agreement, as well as the 2022 Senior Notes and 2025 Senior Notes. Historical information has been retroactively reclassified to reflect Oshkosh Defense as a Guarantor for all periods impacted.
	Under the Indentures governing the 2022 Senior Notes and 2025 Senior Notes, a Guarantor’s guarantee of such Senior Notes will be automatically and unconditionally released and will terminate upon the following customary circumstances: (i) the sale of such Guarantor or substantially all of the assets of such Guarantor if such sale complies with the Indentures; (ii) if such Guarantor no longer guarantees certain other indebtedness of the Company; or (iii) the defeasance or satisfaction and discharge of the Indentures. The following condensed supplemental consolidating financial information reflects the summarized financial information of Oshkosh Corporation, the Guarantors on a combined basis and Oshkosh Corporation’s non-guarantor subsidiaries on a combined basis (in millions):
