Summary of Significant Accounting Polocies [Abstract]

Consolidation, Policy [Policy Text Block]

Basis of Presentation and Principles of Consolidation —

The consolidated financial statements of Sauer-Danfoss Inc. and subsidiaries (the Company) included herein have been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission, and represent the consolidation of all companies in which the Company has a controlling financial ownership interest or a majority of the interest in earnings or losses. Certain information and disclosures normally included in comprehensive financial statements, prepared in accordance with U.S. generally accepted accounting principles (GAAP), have been condensed or omitted pursuant to such rules and regulations, although the Company believes that the disclosures are adequate to make the information presented not misleading. In the opinion of management, the financial statements reflect all adjustments necessary to present fairly the Company's consolidated financial position, results of operations and cash flows for the periods presented. It is suggested that these interim financial statements be read in conjunction with the consolidated financial statements and notes thereto included in the Company's latest annual report on Form 10-K as filed with the Securities and Exchange Commission on March 1, 2012.

Use of Estimates, Policy [Policy Text Block]

Use of Estimates —

In preparing the consolidated financial statements in conformity with U.S. GAAP, management must make decisions that impact the reported amounts of assets, liabilities, revenues, expenses, and the related disclosures, including disclosures of contingent assets and liabilities. Such decisions include the selection of the appropriate accounting principles to be applied and the assumptions on which to base accounting estimates. Estimates are used in determining, among other items, inventory valuation, warranty reserves, allowance for doubtful accounts, valuation allowances on deferred tax assets, pension and postretirement accruals, employee incentive accruals, useful lives for intangible assets, and future cash flows associated with impairment testing for goodwill and other long-lived assets. These estimates and assumptions are based on management's best estimates and judgments. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors that management believes to be reasonable under the circumstances, including the current economic environment, adjusting such estimates and assumptions when facts and circumstances dictate. A number of these factors include, among others, the economic conditions, restricted credit markets, foreign currency, and higher commodity costs, all of which impact such estimates and assumptions. As future events and their effects cannot be determined with precision, actual amounts could differ significantly from those estimated at the time the consolidated financial statements are prepared. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.
