EXHIBIT 31b
Certifications

I, Christopher J. Eperjesy, certify that:

1.  I have reviewed this annual report on Form 10-K of Twin Disc, Incorporated;

2.  Based on my knowledge, this annual report does not contain any untrue
    statement of a material fact or omit to state a material fact necessary to
    make the statements made, in light of the circumstances under which such
    statements were made, not misleading with respect to the period covered by
    this annual report;

3.  Based on my knowledge, the financial statements, and other financial
    information included in this annual report, fairly present in all material
    respects the financial condition, results of operations and cash flows of
    the registrant as of, and for, the periods presented in this annual report;

4.  The registrant's other certifying officers and I are responsible for
    establishing and maintaining disclosure controls and procedures (as defined
    in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the registrant and have:
     a)  designed such disclosure controls and procedures, or caused such
     disclosure controls and procedures to be designed under our supervision, to
     ensure that material information relating to the registrant, including its
     consolidated subsidiaries, is made known to us by others within those
     entities, particularly during the period in which this annual report is
     being prepared;
     b)  evaluated the effectiveness of the registrant's disclosure controls and
     procedures and presented in this annual report our conclusions about the
     effectiveness of the disclosure controls and procedures, as of the end of
     the period covered by this annual report based on such evaluation; and
     c)  disclosed in this annual report any change in the registrant's internal
     control over financial reporting that occurred during the registrant's most
     recent fiscal quarter (the registrant's fourth fiscal quarter in the case
     of this annual report) that has materially affected, or is reasonably
     likely to materially affect, the registrant's internal control over
     financial reporting; and

5.  The registrant's other certifying officers and I have disclosed, based on
    our most recent evaluation of internal control over financial reporting, to
    the registrant's auditors and the audit committee of registrant's board of
    directors (or persons performing the equivalent functions):
     a)  all significant deficiencies in the design or operation of internal
     control over financial reporting which are reasonably likely to adversely
     affect the registrant's ability to record, process, summarize and report
     financial information; and
      b)  any fraud, whether or not material, that involves management or other
     employees who have a significant role in the registrant's internal control
     over financial reporting.
