                         ----------------------------

Benefits Committee
Twin Disc, Incorporated - 
  Accelerator 401(k) Savings Plan
Racine, Wisconsin


     We have audited the accompanying statements of net assets available for
benefits of the Twin Disc Accelerator-401(k) Savings Plan as of December 31, 
2004 and 2003, and the related statements of changes in net assets available 
for benefits for the years then ended.  These financial statements are the
responsibility of the Plan's management.  Our responsibility is to express an
opinion on these financial statements based on our audits.  
     
     We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States).  Those standards require
that we plan and perform the audit to obtain reasonable assurance about whether
the financial statements are free of material misstatement.  An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements.  An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation.  We believe that our
audits provide a reasonable basis for our opinion.
     
     In our opinion, the financial statements, referred to above, present 
fairly, in all material respects, the net assets available for benefits of the
Plan as of December 31, 2004 and 2003 and the changes in its net assets 
available for benefits for the years then ended in conformity with accounting
principles generally accepted in the United States of America.

     Our audit was conducted for the purpose of forming an opinion on the 
basic financial statements taken as a whole.  The supplemental Schedule of 
Assets Held for Investment Purposes-December 31, 2004, is presented for the
purpose of additional analysis and is not a required part of the basic 
financial statements but is supplementary information required by the 
Department of Labor's rules and Regulations for Reporting and Disclosure under
the Employee Retirement Income Security Act of 1974.  This supplemental 
schedule is the responsibility of the Plan's manangement.  The supplemental
schedule has been subjected to the auditing procedures applied in the audits of
the basic financial statements and, in opinion, is fairly stated in all material
respects in relation to the basic financial statements taken as a whole.

                                Notes to Financial Statements

1.  Basis of Presentation and Significant Accounting Policies
-------------------------------------------------------------

     General
     -------

     The following brief description of the Twin Disc, Incorporated - 
Accelerator 401(k) Savings Plan (the "Plan") is provided for general 
information purposes only.  Participants should refer to the plan agreement
for a more complete description of the Plan's provisions.  The Plan, 
established April 1, 1986, is a defined contribution plan covering 
substantially all Twin Disc, Incorporated (the "Company") domestic employees
and is subject to the provisions of the Employee Retirement Income Security 
Act of 1974 ("ERISA").
         
     Eligibility
     -----------

     An employee of the Company is eligible for plan participation after 
completing two months of employment.
         
     Contributions
     -------------

     Participants may elect to contribute on a pre-tax basis up to 100% of
annual gross income with contributions limited under provisions of the Internal
Revenue Code.
         
     For participants who are employed by Twin Disc, Inc., the Company 
contributes an amount equal to a percentage of each participant's 401(k) 
contributions, up to 6% of compensation.  The contribution percentage for the
years ended December 31, 2004 and 2003 was 50%.  For participants who are 
employed by the Twin Disc South East subsidiary, the Company contributes a
matching contribution equal to 25% of each participant's 401(k) contributions,
up to 6% of compensation, and a profit sharing contribution equal to 2.5% of
each participant's compensation.  The Internal Revenue Code has set a maximum
of $13,000 and $12,000 for tax-deferred contributions that may be excluded for
any individual participant in 2004 and 2003, respectively.  The Internal 
Revenue Code also allows additional catch-up contributions for participants age
fifty and over.  The maximum additional contribution allowed was $3,000 and 
$2,000 in 2004 and 2003, respectively.  No federal income tax is paid on the 
tax-deferred contributions and growth thereon until the participant withdraws
them from the Plan.
         
     The Plan enables participants to allocate their contributions and account
balances among various investment options offered by the Plan.  Assets of the 
Plan are segregated and invested based upon the total allocation of the 
participants' accounts.  Participants may direct such allocations in any whole
percentage increment and allocations can be changed at any time.
         
     Vesting 
     -------
    
     Participants are immediately 100% vested in their individual account 
balances.
         
     Withdrawals
     -----------
    
     After-tax contributions may be withdrawn at any time upon receipt of 
written notice by the Trustee.  Pre-tax contributions may only be withdrawn,
prior to employment termination, in the event of severe financial hardship or
once annually upon attainment of age 59 1/2.  A final distribution is paid to
the participant upon termination of employment with the Company. Final
distributions in excess of $5,000 may be deferred as elected by the participant
until age 70 1/2.

-------------------------------------------------------------------------

     Investment Valuation
     --------------------
    
     Investments of the Plan are stated at fair value. The values of 
investments in mutual funds and common stocks are determined by the last 
reported market price on the last business day of the year. Investments in
collective trust funds, other than the T. Rowe Price Stable Value Common Trust
Fund (see below), are valued at redemption prices established by the trustee of
the funds based on the quoted market prices of the underlying investments.
Participant loans are valued at cost which approximates fair value.  The Plan
presents in the statement of changes in net assets, the net appreciation 
(depreciation) in the fair value of its investments, which consists of the 
realized gains or losses and the unrealized appreciation (depreciation) on 
those investments. Purchases and sales of investments are recorded on a 
trade-date basis. Dividends are recorded on the ex-dividend date. Interest is
recognized when earned.

     The fair value of the T. Rowe Price Stable Value Common Trust Fund is 
determined by T. Rowe Price Retirement Plan Services, Inc.  The fair value of
the Strong Stable Value Fund was determined by Strong Investments, Inc.  The
collective trust fund invests in short-term and long-term conventional and 
synthetic investment contracts issued by insurance companies and other 
institutions that meet the high credit quality standards established by Strong
and T. Rowe Price.  The investment contracts are recorded at contract value 
(which represents contributions received, plus interest, less plan 
withdrawals), which approximates fair value at December 31, 2004.

3.  Income Tax Status
---------------------

     The Plan obtained its latest determination letter on March 19, 2002, in
which the Internal Revenue Service stated the Plan as then designed, was in 
compliance with the applicable requirements of the Internal Revenue Code.  The
Plan administrator and the Plan's tax counsel believe that the Plan is 
currently designed and being operated in compliance with the applicable 
requirements of the Internal Revenue Code.  Therefore, no provision for income
taxes has been included in the Plan's financial statements.
         
         
4.  Termination of Plan
-----------------------

     Although the Company has not expressed any intent to terminate the Plan, 
it may do so at any time.


5.  Party-in-Interest Transactions
----------------------------------

     Transactions involving employer securities, funds administered by T. Rowe
Price Trust Company, the current trustee of the Plan, funds administered by T.
Rowe Price Retirement Plan Services, Inc., the recordkeeper of the Plan, and 
participant loans are considered party-in-interest transactions.  These 
transactions are not, however, considered prohibited transactions under 
29 CFR 408(b) of the ERISA regulations.


6.  Amounts Allocated to Withdrawn Participants
-----------------------------------------------

     Plan assets of $9,086,930 and $8,608,508 have been allocated to the
accounts of persons who are no longer active participants of the Plan as of 
December 31, 2004 and 2003, respectively, but who have not yet received 
distributions as of that date.
         
         
7.  Use of Estimates 
--------------------

     The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires 
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the dates of the financial statements and the 
reported amounts of additions and deductions during the reporting periods.  
Actual amounts could differ from those estimates.

8.  Risks and Uncertainties 
---------------------------

     The Plan's investments are exposed to various risks, such as interest 
rate, market and credit risks. Due to the level of risk associated with certain
investments and the level of uncertainty related to changes in the values of 
investments, it is at least reasonably possible that changes in risks in the 
near term would materially affect participants' account balances and the 
amounts reported in the Statements of Net Assets Available for Benefits and the
Statements of Changes in Net Assets Available for Benefits.
