                     Report of Independent Accountants


To the Participants and Administrator
of the Twin Disc, Incorporated - The
Accelerator 401(k) Savings Plan

In our opinion, the accompanying statements of net assets available for
benefits and the related statement of changes in net assets available for
benefits present fairly, in all material respects, the net assets available
for benefits of the Twin Disc, Incorporated - The Accelerator 401(k) Savings
Plan (the "Plan") at December 31, 2001 and 2000, and the changes in net assets
available for benefits for the year ended December 31, 2001 in conformity with
accounting principles generally accepted in the United States of America.
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 of these statements in
accordance with auditing standards generally accepted in the United States of
America, which 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, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation.  We believe that
our audits provide a reasonable basis for our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole.  The supplemental schedules as listed
in the accompanying index are presented for the purpose of additional analysis
and are not a required part of the basic financial statements but are
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.  These supplemental schedules are the responsibility of
the Plan's management.  The supplemental schedules have been subjected to the
auditing procedures applied in the audits of the basic financial statements
and, in our opinion, are fairly stated in all material respects in relation to
the basic financial statements taken as a whole.

     information purposes only.  Participants should refer to the plan

     General

     The Plan, established April 1, 1986, is a defined contribution plan

2.   Summary of Accounting Policies
     - - - - - - - - - - - - - - - -

     Basis of Accounting
     - - - - - - - - - -
     The financial statements of the Plan are prepared under the accrual
     method of accounting.

     Investments
     - - - - - -
     Investment 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 common trust funds are valued at redemption prices established by the
     Trustee. 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.

 8

     Administrative Expenses
     - - - - - - - - - - - -
     Certain administrative expenses of the Plan are paid by the Company at
     its discretion.  The remaining administrative expenses are paid by the
     Plan.

     Benefit Payments
     - - - - - - - - -
     Benefits are recorded when paid.

     Use of Estimates
     - - - - - - - -
     The preparation of financial statements in conformity with generally
     accepted accounting principles 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.

     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 Statement of Changes in Net Assets
     Available for Benefits.

4.   Tax Status
     - - - - - -
     The Internal Revenue Service has determined and informed the Company by a
     letter dated March 19, 2002, that the Plan is designed in accordance with
     applicable sections of the Internal Revenue Code ("IRC").  The Plan
     administrator believes that the Plan is currently being operated in
     compliance with the appropriate requirements of the IRC.

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

6.   Party-in-Interest Transactions
     - - - - - - - - - - - - - - - -
     Transactions involving employer securities, funds administered by
     Firstar, the trustee of the Plan, and participant loans are considered
