                    NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)

A.     Basis of Presentation

The unaudited financial statements have been prepared by the Company pursuant
to the rules and regulations of the Securities and Exchange Commission (SEC)
and, in the opinion of the Company, include all adjustments, consisting only
of normal recurring items, necessary for a fair statement of results for each
period.  Certain information and footnote disclosures normally included in
financial statements prepared in accordance with generally accepted accounting
principles have been condensed or omitted pursuant to such SEC rules and
regulations.  The Company believes that the disclosures made are adequate to
make the information presented not misleading.  It is suggested that these
financial statements be read in conjunction with financial statements and the
notes thereto included in the Company's latest Annual Report.  The year end
condensed balance sheet data was derived from audited financial statements but
does not include all disclosures required by generally accepted accounting
principles.

C.     Contingencies

The Company is involved in various stages of investigation relative to
hazardous waste sites, two of which are on the United States EPA National
Priorities List (Superfund sites).  The Company's assigned responsibility at
each of the Superfund sites is less than 2%.  The Company has also been
requested to provide administrative information related to two other potential
Superfund sites but has not yet been identified as a potentially responsible
party.  Additionally, the Company is subject to certain product liability
matters in the normal course of business.

At December 31, 1999 the Company has accrued approximately $1,050,000, which
represents management's best estimate available for possible losses related to
these contingencies.  This amount has been provided over the past several
years.  Based on the information available, the Company does not expect that
any unrecorded liability related to these matters would materially affect the
consolidated financial position, results of operations or cash flows.

                  MANAGEMENT DISCUSSION AND ANALYSIS

Net sales for the second quarter were 11 percent greater than the same period
a year ago primarily due to acquisitions made during the last half of fiscal
year 1999.  Net earnings of $693,000 represented a welcome turnaround from the
$291,000 loss reported in last year's second quarter.  Generally, market
conditions were stable with evidence of improving trends in specific market
segments.

The increase in shipments from our domestic manufacturing facilities consisted
mainly of industrial products.  Most of the increase was attributable to the
power take-off product line purchased a year ago.  There also was some
improvement in sales of Arneson marine surface drives and power-shift
transmissions for construction equipment.  Renewal part sales to the
aftermarket were comparable to a year ago and have begun to recover somewhat
from the low-point at the end of last fiscal year.  Shipments of marine
transmissions were down slightly from last year, but demand has been
relatively stable in both pleasure craft and commercial markets.  Higher sales
volume in Europe was attributable to our Italian manufacturing subsidiary
acquired last February with shipments from our Belgium operation about even
with last year's second quarter.  Most of our distribution subsidiaries
reported higher sales compared with a year ago, including a significant
increase in Singapore reflecting the beginning of economic recovery in Asia.
During the past year, the dollar has appreciated by approximately 10 percent
versus the currencies in which we operate mitigating the dollar impact of the
increased shipping levels overseas.

The consolidated gross margin was higher than in the previous three quarters
but was down modestly from the same period last year.  As a result of higher
volume and better productivity, domestic manufacturing margins were up from a
year ago.  At our Belgian subsidiary, the gross margin was down about four
percentage points due to less favorable product mix and to the lower
production levels associated with inventory reduction activity.

Marketing, engineering and administrative expenses were below the second
quarter last year as a result of personnel and other cost reductions
implemented in fiscal 1999.  Offsetting some of those savings were the
additional expenses incurred at the newly acquired Italian subsidiary.
Statutory income tax rates are comparable with a year ago; but domestic
losses, which were taxed at a relatively low rate, resulted in a higher than
normal effective tax rate.

Working capital, at $59 million, was comparable to the previous quarter but
much greater than at the prior fiscal year-end.  The increase was caused by
restructuring much of the current borrowings at year-end to long-term debt in
the first fiscal quarter.  Accounts receivable was up from the previous
quarter as a result of increased sales, and inventory declined slightly as
turnover improved.  Both receivables and inventory were comparable to balances
at the prior fiscal year-end.  While debt levels are high by our historical
standards, our balance sheet is strong and we continue to have sufficient
liquidity for near-term needs.

As a final report on Year 2000 Readiness, we have started the new millennium
with all systems operational and business being conducted without
interruption.

Report of Independent Accountants


To the Board of Directors
Twin Disc, Incorporated
Racine, Wisconsin

We have reviewed the accompanying condensed consolidated balance sheet of Twin
Disc, Incorporated and subsidiaries as of December 31, 1999, and the related
condensed consolidated statements of operations for the three and six-month
periods ended December 31, 1999 and 1998 and the related condensed
consolidated statements of cash flows for the six-month periods ended December
31, 1999 and 1998.  These financial statements are the responsibility of the
Company's management.

We conducted our review in accordance with standards established by the
American Institute of Certified Public Accountants.  A review of interim
financial information consists principally of applying analytical review
procedures to financial data, and making inquiries of persons
responsible for financial accounting matters.  It is substantially less
in scope than an audit in accordance with generally accepted auditing
standards, the objective of which is the expression of an opinion
regarding the financial statements taken as a whole.  Accordingly, we do
not express such an opinion.

Based on our review, we are not aware of any material modifications that
should be made to the accompanying condensed consolidated financial statements
referred to above for them to be in conformity with generally accepted
accounting principles.

We have previously audited, in accordance with generally accepted
auditing standards, the consolidated balance sheet as of June 30, 1999,
and the related consolidated statements of operations, changes in
shareholders' equity and comprehensive income, and cash flows for the year
then ended (not presented herein); and in our report dated July 23, 1999, we
expressed an unqualified opinion on those consolidated financial statements.
In our opinion, the information set forth in the accompanying condensed
consolidated balance sheet as of June 30, 1999, is fairly stated, in all
material respects, in relation to the consolidated balance sheet from
which it has been derived.
