Item 3.  Source and Amount of Funds or Other Consideration

         Pursuant to an agreement, dated January 22, 2000, among Murmann GmbH,
Danfoss and the Holding Company, as amended by an amendment thereto, dated
February 22, 2000 (the "Holding Company Agreement"), prior to consummation of
the Transaction (as defined below), Danfoss is expected to contribute to the
Holding Company, in exchange for shares of the Holding Company's common stock,
all of the outstanding shares of common stock of Danfoss Fluid Power A/S, a
corporation organized under the laws of Denmark, and Danfoss Fluid Power Inc.,
an Illinois corporation (together, the "Danfoss Fluid Power Companies"), and
Murmann GmbH is expected to cause to be contributed to the Holding Company, in
exchange for shares of the Holding Company's common stock, 1,000 shares of Sauer
Common Stock. Additionally, pursuant to the Holding Company Agreement, Murmann
GmbH has granted the Holding Company an irrevocable proxy to vote 10,361,500
shares of Sauer Common Stock (the "Voting Proxy"). The Holding Company's voting
rights will be shared equally by Murmann GmbH and Danfoss.

         The Voting Proxy will terminate upon the earlier of (a) the
contribution by Murmann GmbH of 10,361,500 shares of Sauer Common Stock to the
Holding Company, in exchange for shares of the Holding Company's common stock,
and (b) the dissolution of the Holding Company. Pursuant to the Holding Company
Agreement, Murmann GmbH will not be obligated make such contribution of shares
of Sauer Common Stock to the Holding Company unless the Holding Company receives
a ruling from the United States Internal Revenue Service confirming that the
Holding Company qualifies to receive certain benefits under the proposed
Convention Between the Government of the United States of America and the
Government of the Kingdom of Denmark for the Avoidance of Double Taxation and
the Prevention of Fiscal Evasion with Respect to Taxes on Income (the
"Confirmation"). If the Holding Company does not qualify for such benefits, the
Holding Company may be dissolved.

         In addition, pursuant to the Holding Company Agreement, Murmann GmbH is
obligated (a) in connection with any vote of the holders of Sauer Common Stock,
to vote 6,812,500 shares of Sauer Common Stock, which includes 1,912,500 shares
of Sauer Common Stock expected to be issued to Murmann GmbH in connection with
the termination of the Limited Partnership Agreement (as defined below),
consistent with the Holding Company and (b) not to transfer any of 6,812,500
shares of Sauer Common Stock, which includes 1,912,500 shares of Sauer Common
Stock expected to be issued to Murmann GmbH in connection with the termination
of the Limited Partnership Agreement, outside of the entities and persons under
the control of Klaus H. Murmann (the "Murmann Family") without the prior written
consent of Danfoss.

         Pursuant to a Stock Exchange Agreement, dated as of January 22, 2000,
among the Issuer, Murmann GmbH, Danfoss and the Holding Company (the "Stock
Exchange Agreement"), among other things, the Issuer is expected to acquire all
of the outstanding common stock of Danfoss Fluid Power Companies from the
Holding Company in exchange for 16,149,812 shares of Sauer Common Stock (the
"Transaction"). In addition, on or before December 31, 2000, the Issuer is
expected to acquire from the Holding Company, for additional shares of Sauer
Common Stock, all of the assets of Danfoss related to the mobile hydraulics
operations of Danfoss in Australia, Belgium, Brazil, Holland, Hong Kong, Japan,
Mexico, New Zealand, Portugal, Spain and Switzerland (the "Secondary
Acquisition"). The number of shares of Sauer Common Stock to be issued to the
Holding Company in connection with the Secondary Acquisition will be based upon
the same financial parameters used to calculate the number of shares of Sauer
Common Stock issued by the Issuer in connection with the Transaction, including
the closing stock price of Sauer Common Stock as of the date of consummation of
the Transaction and, therefore, cannot be specifically calculated at this time.
However, the Issuer expects that the number of additional shares of Sauer Common
Stock to be issued in connection with the Secondary Acquisition will be between
approximately 2,000,000 shares and 3,000,000 shares of Sauer Common Stock.

         The Stock Exchange Agreement was previously filed by the Issuer with
the Securities and Exchange Commission on February 10, 2000 as Annex A to the
Preliminary Proxy Statement on Schedule 14A and is hereby incorporated into this
Schedule 13D by reference.

         In connection with the Transaction, the Issuer is expected to terminate
an amended and restated limited partnership agreement, dated April 14, 1998,
among the Issuer, Sauer-Sundstrand GmbH, Sauer GmbH, EMF and Sauer GmbH & Co.
Hydraulik KG (the "Limited Partnership Agreement"). Pursuant to the terms of the
Limited Partnership Agreement, upon termination thereof, among other things,
Sauer is required to issue 1,912,500, 225,000 and 112,500 shares of Sauer Common
Stock to Murmann GmbH (as the general partner of Sauer GmbH & Co.

Hydraulik KG), EMF and Sauer GmbH, respectively.

         Jorgen Clausen, President, Chief Executive Officer and a director of
Danfoss, beneficially owns 58,000 shares of Sauer Common Stock. Such ownership
represents 0.2% of the outstanding shares of the Issuer. Jorgen Clausen has
acquired all such shares of Sauer Common Stock with personal funds.

Item 4.  Purpose of Transaction

         The Holding Company acquired the Voting Proxy in connection with the
Transaction and, upon consummation of the Transaction, will receive 16,149,812
shares of Sauer Common Stock. Jorgen Clausen acquired Sauer Common Stock for
investment purposes. Jorgen Clausen has not formulated any plans or proposals
that would result in any of the actions enumerated in Items 4(a)-(j) of Schedule
13D.

         (a) As described more fully in Item 3 above, upon consummation
of the Transaction, the Holding Company will receive 16,149,812 shares of Sauer
Common Stock. Additionally, as described more fully in Item 3 above, immediately
upon receipt of the Confirmation, Murmann GmbH is obligated to cause to be
contributed to the Holding Company 10,361,500 shares of Sauer Common Stock.
Also, as described more fully in Item 3 above, upon termination of the Limited
Partnership Agreement, Murmann GmbH, EMF and Sauer GmbH will receive 1,912,500,
225,000 and 112,500 shares of Sauer Common Stock, respectively. Further, as



                                  Page 20 of 38
<PAGE>



described more fully in Item 3 above, as a result of the Secondary Acquisition,
it is expected that the Holding Company will receive between approximately
2,000,000 shares and 3,000,000 shares of Sauer Common Stock.

         (b)  As described more fully in Item 3 above, this statement
relates to certain transactions related to the acquisition by the Issuer of all
of the outstanding shares of the Danfoss Fluid Power Companies pursuant to the
Stock Exchange Agreement.

         (c)  Not applicable.

         (d)  Pursuant to the Holding Company Agreement, upon consummation
of the Transaction, the Certificate of Incorporation and Bylaws of the Issuer
will be amended to provide that the number of directors comprising the fully
constituted board of directors of the Issuer will be increased to ten. Director
candidates will be identified by a two member nominating committee comprised of
a representative of the Murmann Family and a representative of Danfoss. The
representative of each of the Murmann Family and Danfoss will be entitled to
identify for recommendation to the Issuer's board of directors three candidates
for director who may be associated or affiliated with the Murmann Family or
Danfoss. The representative of each of the Murmann Family and Danfoss will each
identify two additional candidates for director. One of the additional director
candidates recommended by the representative of the Murmann Family will be the
Chief Executive Officer and President of the Issuer and the remaining three
director candidates must be independent from and not associated or affiliated
with the Murmann Family or Danfoss. After the person serving as Chief Executive
Officer and President ceases to serve in such capacity, the representative of
the Murmann Family will be entitled to identify for recommendation to the
Issuer's board of directors a second independent director candidate to replace
the Chief Executive Officer and President.

         Additionally, pursuant to the Holding Company Agreement, upon
consummation of the Transaction, Jorgen Clausen will become the Vice Chairman of
the Issuer's board of directors. At the time that Klaus H. Murmann ceases to act
as Chairman of the Issuer's board of directors and, in any event, no later than
the fourth anniversary of the consummation of the Transaction, Jorgen Clausen
will become the Chairman of the Issuer's board of directors, holding such office
until, at the latest, March 31, 2008.

         Further, pursuant to the Holding Company Agreement and subject to the
approval of 80% of the outstanding shares of Sauer Common Stock, the Certificate
of Incorporation of the Issuer will be amended to remove the classifications of
the Issuer's board of directors and allow for removal of directors without cause
by the holders of a majority of the outstanding shares of Sauer Common Stock.
Accordingly, each director would serve a one-year term. Also, pursuant to the
Holding Company Agreement, upon consummation of the Transaction, the Bylaws of
the Issuer will be amended to provide that certain material actions of the
Issuer's board of directors will require the approval of at least 80% of the
fully constituted board of directors.

         (e)  As described more fully in Item 3 and Item 4(a) above, upon
consummation of the Transaction and the Secondary Acquisition and in connection
with the termination of the Silent Partnership Agreement, the Issuer is expected
to issue shares of Sauer Common Stock. Additionally, because the number of
shares of Sauer Common Stock to be issued to the Holding Company in connection
with the Transaction, when added to the number of shares of Sauer Common Stock
currently outstanding, would exceed the 45,000,000 shares of Sauer Common



                                  Page 21 of 38


<PAGE>



Stock currently authorized, concurrent with the consummation of the Transaction,
the Issuer is expected to amend its Certificate of Incorporation to increase the
number of authorized shares of Sauer Common Stock by 30,000,000 from 45,000,000
to 75,000,000.

         (f)     Not applicable.

         (g)     Except as set forth in Item 4(d) above, not
applicable.

         (h)-(i) Not applicable.

         (j)     Except as set forth above, neither the Reporting Persons nor
the Danfoss Control Persons currently have any plans or proposals which relate
to or would result in any of the actions described in, or similar to, the
actions enumerated in Items 4(a) - (j) of Schedule 13D (although the Reporting
Persons and the Danfoss Control Persons reserve the right to develop such
plans).

                             JOINT VENTURE AGREEMENT

between

K. MURMANN Verwaltungsgesellschaft mbH, Kiel, Germany,
represented by Klaus H. Murmann,

                                      - hereinafter referred to as "MURMANN" --

and

DANFOSS A/S, Nordborg, Denmark, represented by Jorgen Mads Clausen,

                                      - hereinafter referred to as "DANFOSS" --

MURMANN and DANFOSS hereinafter each called "the Party" or also collectively
referred to as "the Parties" --

and

DANFOSS MURMANN Holding A/S, Nordborg, Denmark,

                                      - hereinafter referred to as "Holding" --

Preamble

(a)      MURMANN and related entities/persons control (directly or indirectly)
         by majority stockholdership SAUER Inc., a Delaware corporation having
         its headquarters in Ames, Iowa, USA (hereinafter referred to as "SAUER
         Inc." or "the Company").

         SAUER Inc. is active in the design, manufacture and sale of highly
         engineered hydraulic systems and components for use primarily in
         demanding applications of off-highway mobile equipment (hereinafter
         referred to as "Mobile Hydraulics").

         DANFOSS has -- inter alia -- also substantial activities in special
         fields of the design, manufacture and sale of Mobile Hydraulics mainly
         concentrated in the DANFOSS Fluid Power A/S, Nordborg, Denmark and the
         DANFOSS Fluid Power Inc., Racine, Wisconsin, USA as further described
         in the Stock Exchange Agreement (Appendix 1).

(b)      Both, MURMANN and DANFOSS, have become convinced that a close
         cooperation in the field of Mobile Hydraulics by way of combining the
         respective activities of SAUER Inc. and DANFOSS will strongly improve
         the competitive strength and would therefore be in the mutual interest
         of SAUER Inc. and DANFOSS. The overall objective of such


                                        1

<PAGE>



         combination is to favour a growth and rationalisation strategy that
         will position the combined business as an important player on the
         markets with low costs, high quality and innovation will be a
         substantial value driver compared with other solutions available.

(c)      For this purpose, MURMANN and DANFOSS will concentrate the Mobile
         Hydraulics Business of SAUER Inc. and DANFOSS by involving a new
         corporation to be owned by the Parties, the Holding. The Holding will
         hold the majority of SAUER Inc. ordinary common stock in direct
         successorship of MURMANN's present majority position. To reach this
         target MURMANN will contribute to Holding shares of SAUER Inc. ordinary
         common stock and DANFOSS will contribute to Holding the DANFOSS Mobile
         Hydraulics Business. The contribution from DANFOSS will be transferred
         from Holding to SAUER Inc. against shares of SAUER Inc. ordinary common
         stock newly to be issued to Holding according to the Stock Exchange
         Agreement.

After the Closing Date as defined in the Stock Exchange Agreement, but before 31
December 2000, DANFOSS will further contribute its mobile hydraulics business
against shares in Holding in Holland, Belgium, Spain, Portugal, Switzerland,
Japan, Singapore (which also covers sales in ASEAN countries), Hong Kong, New
Zealand, Australia, Brazil (which also covers sales in South America) and Mexico
through Holding to SAUER Inc. The provisions of this Agreement, in particular
Articles 2 and 4, shall apply correspondingly. Furthermore, DANFOSS will after
the Closing Date on conditions described in the Stock Exchange Agreement
continue to act as a distributor for SAUER Inc. in Iceland, Russia, India and
South Africa.

SAUER Inc. will further on operate under the name "SAUER-DANFOSS Inc."

Now, therefore, in consideration of the premises and covenants set forth herein,
MURMANN and DANFOSS enter into this Joint Venture Agreement (hereinafter
referred to as "the Agreement") and hereby agree as follows:

                                       A.

                         Formation of the Joint Venture

         - MURMANN:

           10.362.500 shares of SAUER Inc. ordinary common stock,

         - DANFOSS:

           the DANFOSS Mobile Hydraulics Business.

(b)      By way of capital increase of the Holding, the Parties shall receive
         Shares of the Holding in proportion to 10.362.500 (MURMANN) to the
         number of SAUER Inc. ordinary common stock Holding has received as
         compensation for the DANFOSS Mobile Hydraulics Business amounting to
         16.149.812 (DANFOSS).

         In the result, the parties receive for 1 (one) SAUER Inc. share (with a
         nominal value of US-$ 0,01 each) 1 (one) Holding Share (with a nominal
         value of DKK 1 each). The details of the contributions in kind are set
         forth in the shareholders' resolution concerning the capital increase
         based on MURMANN's contribution attached as draft hereto as Appendix 2
         and in the shareholders' resolution based on the contribution of
         DANFOSS attached as draft hereto as Appendix 3.

(c)      DANFOSS will acquire 50% of the Class A shares amounting to DKK
         500.000, which MURMANN has acquired according to Article 1 above, the
         compensation being half of MURMANN's expenditures on acquiring the
         Holding.

(d)      The Parties agree to contribute additional shares of SAUER Inc.
         ordinary common stock to Holding at an equal amount in case of capital
         increase of SAUER Inc. by issuance of new shares of ordinary common
         stock in order always to keep the majority position of the Holding
         (more than 50%). As long as MURMANN has not contributed the number of
         shares Holding has received as compensation for the DANFOSS Mobile
         Hydraulics Business, first, before the equal commitment of both Parties
         mentioned above, MURMANN shall contribute the missing shares to
         maintain Holding's majority position with SAUER Inc.

(e)      MURMANN is entitled to contribute at any time additional shares of
         SAUER Inc. ordinary common stock against new Shares of Holding at a
         corresponding amount according to the provision of (b) above limited to
         a 50% shareholdership in the Holding, however MURMANN is obligated on
         or before December 31, 2003 to contribute and maintain ownership
         thereafter of additional SAUER Inc. shares to Holding so his total
         contribution to Holding of SAUER Inc. shares is minimum 25.1% of the
         total issued SAUER Inc. shares calculated on a diluted basis.

(f)      Each Party is entitled to withdraw at any time after December 31, 2003
         shares of SAUER Inc. ordinary common stock against the return of Shares
         of Holding, however each Party is obligated to keep at all times a
         total contribution of minimum 25.1% of the total issued SAUER Inc.
         shares calculated on a fully diluted basis. The Parties are further in
         agreement to reduce the share capital of Holding, if it is necessary,
         to provide for such withdrawal by one Party.

(g)      One Holding Share shall always equal one SAUER Inc. share common stock.
         This principle contains generally the formula for determining the
         number of Shares of Holding which either Party shall receive or
         contribute to Holding if such Party either contributes or withdraws
         SAUER Inc. shares from Holding.

(h)      MURMANN guarantees that the 6.812.500 shares owned by K. Murmann & Co.
         KG and by MURMANN (conversion of silent partnership shares) will vote
         together with Holding in any Shareholder/Board vote of SAUER Inc. The
         above mentioned 6.812.500 shares shall not be transferred to a third
         Party (outside the MURMANN group consisting of the K. Murmann & Co. KG
         and its partners and MURMANN and its subsidiaries) without the prior
         written consent of DANFOSS, such consent not to be unreasonably
         withheld.

         Hydraulics Business to SAUER Inc. against 16,149.812 newly issued

(b)      The contribution and assignment mentioned under subsection a) above is
         set forth in detail in the Stock Exchange Agreement between SAUER Inc.
         and the Holding.

                                    Article 4

        Warranties of the Parties in connection with their contributions

(a)      DANFOSS shall grant in favour of MURMANN and the Holding the identical
         representations, warranties, covenants and indemnities regarding its
         contribution as the Holding has to grant in favour of SAUER Inc.
         according to the Stock Exchange Agreement, but shall only indemnify and
         hold harmless SAUER Inc. from any such claims pursuant of the Stock
         Exchange Agreement.

         If a claim will be raised against Holding under the Stock Exchange
         Agreement, DANFOSS shall hold harmless Holding from any such claims.
         DANFOSS shall at its own expense choose and instruct counsel to defend
         Holding in connection with such claims and shall decide the existence,
         timing and details of any settlement by Holding of such claims as set
         forth in the Stock Exchange Agreement.

(b)      MURMANN and Holding shall grant in favour of DANFOSS with regard to the
         compensation for the contribution of the DANFOSS Mobile Hydraulics
         Business the representations, warranties, covenants and indemnities as
         Sauer Inc. has to grant in favour of Holding according to the Stock
         Exchange Agreement, except for claims under Section 9.04 and 905, which
         Sauer Inc will pay to DANFOSS in full. As regards claims of DANFOSS the
         Parties agree as follows:

         Any claim of DANFOSS based on the representations, warranties,
         covenants and indemnities described in (b) above is limited to the
         amount equal to the percentage of shares of SAUER Inc. Holding has
         received as compensation for the DANFOSS Mobile Hydraulics Business
         contributed to SAUER Inc. at Closing.

         In case of such claims of DANFOSS in accordance with the Stock Exchange
         Agreement MURMANN agrees -- for the benefit of SAUER Inc. and its
         minority shareholders -- to hold SAUER Inc. harmless from such claims
         of Holding, and DANFOSS agrees that MURMANN can compensate DANFOSS by
         paying DANFOSS 80% of the amount to be paid by MURMANN as described
         above. SAUER Inc. has agreed that MURMANN is entitled at its own
         expense to choose and instruct counsel to defend SAUER Inc. in
         connection with such claims and shall decide the existence, timing and
         the details of any settlement by SAUER Inc. of such claims.

         MURMANN shall pay the amount to be paid by MURMANN as described above
         by transferring shares of SAUER Inc. ordinary common stock to DANFOSS,
         the valuation of the shares shall be the average price at which such
         shares have been traded on the New York Stock Exchange during the last
         two weeks before MURMANN'S indemnification is


                                        5

<PAGE>



         payable, or by transferring an equal number or Shares in Holding.
         Instead of payment by shares, payment can also take place by cash.

         The Parties agree that with the aforementioned 80% payment made by
         MURMANN to DANFOSS, Holding is fully compensated for such claims
         against SAUER Inc. and against MURMANN, and that DANFOSS is fully
         compensated for such claims with respect to MURMANN's contribution to
         the Holding and on payment to DANFOSS, Holding and DANFOSS shall give
         full release regarding such claims.

         The following example may clarify the agreement set forth above under
         this subsection:

         Damage with SAUER Inc.:                                   US$ 8 million
         Minus basket                                              US$ 5 million
         Relevant damage for indemnification:                      US$ 3 million
         Participation of Holding on total SAUER Inc. outstanding stock received
         as compensation for the contribution of the DANFOSS Mobile Hydraulics
         Business:

                  1/3 (one third) of 3 million = US$ 1 million

         MURMANN'S liability to pay to DANFOSS: 80% of US$ 1 million = US$
         800.000

         (In the above example Holding has received as compensation 1/3 of the
         shares)

(c)      Should a claim arise under a) or b) above, both Parties shall cause on
         one hand SAUER Inc. and its subsidiaries and on the other hand DANFOSS
         Fluid Power A/S and its subsidiaries and DANFOSS Fluid Power Inc. to
         make full disclosure to the other Party in connection with such claims
         consistent with litigation discovery procedure in the USA.

(d)      MURMANN or DANFOSS shall in no event be obligated to indemnify twice
         the same damage under the Stock Exchange Agreement and this Agreement.

         This Agreement shall not expand the Parties' liability under the Stock
         Exchange Agreement.

(e)      Both Parties have been taken external tax advise on the tax conditions
         of the Holding and neither Party has been granting the other Party any
         warranty for present or future tax conditions of the Holding. This
         shall, however, not affect the Parties' rights and obligations
         regarding tax matters under the Stock Exchange Agreement.

         3, 2004 (respectively on the date of the then following Board meeting).
         If he decides so, J.M. Clausen continues as Vice Chairman. If Klaus H.
         Murmann ceases to be a member of the Board of Directors or refuses to
         be the Chairman of the Board of Directors prior to or on April 3, 2002
         (respectively on the date of the then following Board meeting), J.M.

         of the Board or refuses to be Vice Chairman of the Board during the
         time period Klaus H. Murmann is still Chairman, DANFOSS may appoint any
         other Director as Vice Chairman of the Board.

(b)      In the event that J.M. Clausen does not, for any reason whatever,
         become or continue as Chairman, MURMANN agrees to use its best efforts
         to either cause the Vice Chairman to resign or cause the Board to
         remove the Vice Chairman. The Board shall thereafter, in its sole
         discretion, fill the vacancies in both offices. The same applies after

         only serve until they reach the age of 70. After having reached this
         age level they cannot be re-elected and -- in case their term does

         Amendment to the Joint Venture Agreement ("Agreement") between

                  K. Murmann Verwaltungsgesellschaft mbH,
                  Danfoss A/S,
                  Danfoss Murmann Holding A/S

                  dated 22nd January 2000.

Due to still outstanding decisions of certain tax authorities, the Parties agree
to the following amendment to the Joint Venture Agreement:

1.       Murmann shall contribute to Holding in a first step only 1000 Sauer
         Inc. Shares.

         The remaining contribution of 10,361,500 shares shall be made
         immediately after existence of a discretionary ruling of the US Inland
         Revenue Services confirming that Holding is qualified for the benefits
         of the US-Denmark Double Tax Treaty (5% US withholding tax). The same
         shall apply to all further commitments of Murmann to contribute Sauer
         Shares to Holding as provided for under Art. 2(d) and (e).

2.       For the period until the dissolution of Holding, described under
         subsection 5, Murmann hereby grants to Holding the irrevocable voting
         proxy - and Holding hereby accepts such proxy - with respect to all
         Voting Rights out of or in connection with the 10,361,500 shares to be
         contributed to Holding at a later date.

3.       Art. 2(h) shall apply accordingly to Murmann's 10,361,500 shares.

4.       For the purpose of securement of the regulations above, Danfoss is
         entitled to request an adequate escrow concerning the 10,361,500 Sauer
         shares of Murmann.

5.       In case the discretionary ruling has not been obtained, Danfoss may
         decide the dissolution of Holding with effect of the distribution of
         the Sauer Shares to the Shareholders: In such case, the Parties will
         negotiate in good faith to find a solution which meets the intentions
         of the Parties, especially, with regard to the joint ownership of the
         majority in Sauer Inc., as close as possible.
