MTS SELLS AUTOMATION DIVISION

Eden Prairie, Minn., April 11, 2003 - MTS Systems Corporation (NASDAQ: MTSC)
today announced that it has completed agreements for the sale of its Automation
Division based in New Ulm, Minnesota, to Parker Hannifin Corporation (NYSE: PH).
Details of the transaction were not disclosed. Simultaneously, the Company
reconfirmed its previous full year fiscal 2003 earnings per share guidance in
the middle $0.80 range.

"While our resizing efforts for the division were on track, we determined that
the motor and amplifier business was no longer strategic to the overall
direction of the Company," said Sidney W. Emery, Jr., Chairman and CEO of MTS
Systems Corporation. "Thus, divesting the division to a major market player
results in a win/win situation; for our customers, the Automation Division's
employees, Parker Hannifin and MTS. We will continue to focus on our core force
and motion control products and markets where we have solid market positions and
a breadth of opportunities for profitable growth."

"The custom motor business is one that we have admired for some time, so we're
very pleased to add this high-value technology to our portfolio," said Parker
Automation Group President Bob Bond. "The MTS product line complements our
ability to be a leading automation- solution provider for a broad range of
global machine builders. It expands our breadth of our product and channels to
market, and enhances our ability to offer highly customized and innovative
motion systems for premier customer service."

The Automation Division was reported as part of the MTS Factory Automation
Segment. Its fiscal year 2002 revenue was $23.0 million and it had a loss in
2002 as a result of significant restructuring and inventory write-off costs.

The Company expects to have more information regarding the transaction at its
upcoming conference call.
