Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of Prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a twenty percent (20%) change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective Registration Statement.

(3) To remove from registration by means of a post- effective amendment any of the securities being registered which remain unsold at the termination of the offering. (b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

The Board of Directors
Twin Disc, Incorporated
1328 Racine Street
Racine, WI  53403

Gentlemen:

This firm is counsel for Twin Disc, Incorporated ("Company"), which is the
registrant in a Registration Statement under the Securities Act of 1933 on
Form S-8, dated December 11, 1998, relating to the registration of 35,000
shares of the Company's common stock, no par value per share ("Shares"), to be
offered and sold pursuant to the Twin Disc, Incorporated 1998 Stock Option
Plan for Non-Employee Directors.

As counsel, we are familiar with the action taken by the Company in connection
with the authorization of the Shares.  We have examined such records and other
documents as we have deemed necessary for the opinion hereinafter expressed.

Based upon the foregoing, and having regard to legal considerations which we
deem relevant, we are of the opinion that the Shares described in the
Registration Statement will be, when sold, legally issued by the Company,
fully paid and non-assessable, except to the extent provided in Section
180.0622(2)(b), of the Wisconsin Statutes which provides, in part, that
shareholders of a Wisconsin corporation are personally liable to an amount
equal to the consideration for which their shares without par value were
issued for all debts owing to employees of the corporation for services
performed for such corporation, but not exceeding six months' service in any
one case.

We hereby consent to the inclusion of this opinion as an exhibit to the
Registration Statement.

Very truly yours,

von BRIESEN, PURTELL & ROPER, s.c.
