POWER OF ATTORNEY

Know all by these present that the undersigned hereby constitutes and
appoints each of Steven G. Mahon, Catherine Powell, W. Morgan Burns,
Alyn Bedford, Julie Regnier and Lauren Graff, signing singly,
the undersigned's true and lawful attorney-in-fact to:
(1)	execute for and on behalf of the undersigned, in the
undersigned's capacity as an officer and/or director of MTS
Systems Corporation (the "Company"), Forms ID, 3, 4 and 5
(including amendments thereto) in accordance with Section 16(a)
of the Securities Exchange Act of 1934 and the rules and
regulations thereunder;
(2) 	do and perform any and all acts for and on behalf of the
undersigned which may be necessary or desirable to complete and
execute any such Forms ID, 3, 4 or 5 and timely file such forms
(including amendments thereto) and application with the United
States Securities and Exchange Commission and any stock exchange
or similar authority; and
(3) 	take any other action of any type whatsoever in connection with
the foregoing which, in the opinion of such attorney-in-fact, may
be of benefit to, in the best interest of, or legally required
by, the undersigned, it being understood that the documents
executed by such attorney-in-fact on behalf of the undersigned
pursuant to this Power of Attorney shall be in such form and
shall contain such terms and conditions as such attorney-in-fact
may approve in such attorney-in-fact's discretion.
The undersigned hereby grants to each such attorney-in-fact full power and
authority to do and perform any and every act and thing whatsoever requisite,
necessary or proper to be done in the exercise of any of the rights and
powers herein granted, as fully to all intents and purposes as the
undersigned might or could do if personally present, with full power of
substitution or revocation, hereby ratifying and confirming all that such
attorney-in-fact, or such attorney-in fact's substitute or substitutes, shall
lawfully do or cause to be done by virtue of this power of attorney and the
rights and powers herein granted. The undersigned acknowledges that the
foregoing attorneys-in-fact, in serving in such capacity at the request of
the undersigned, are not assuming, nor is the Company or any such attorney-
in-fact's substitute or substitutes assuming, any of the undersigned's
responsibilities to comply with Section 16 of the Securities Exchange Act of
1934.
The undersigned agrees that each such attorney-in-fact herein may rely
entirely on information furnished orally or in writing by the undersigned and
his agents to such attorney-in-fact. The undersigned also agrees to indemnify
and hold harmless the Company and each such attorney-in-fact against any
losses, claims, damages or liabilities (or actions in these respects) that
arise out of or are based upon any untrue statements or omission of necessary
facts in the information provided by the undersigned and his agents to such
attorney-in fact for purposes of executing, acknowledging, delivering or
filing Forms ID, 3, 4 or 5 (including amendments thereto) and agrees to
reimburse such attorney-in-fact for any legal or other expenses reasonably
incurred in connection with investigating or defending against any such loss,
claim, damage, liability or action.
This Power of Attorney supersedes any power of attorney previously executed
by the undersigned regarding the purposes outlined in the first paragraph
hereof ("Prior Powers of Attorney"), and the authority of the attorneys-in-
fact named in any Prior Powers of Attorney is hereby revoked.
This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Forms ID, 3, 4 or 5 with respect to
the undersigned's holdings of and transactions in securities issued by the
Company, unless earlier (a) revoked by the undersigned in a signed writing
delivered to the foregoing attorneys-in-fact or (b) superseded by a new power
of attorney regarding the purposes outlined in the first paragraph hereof
dated as of a later date.
Notwithstanding the foregoing, if any such attorney-in-fact hereafter ceases
to be an employee of the Company, this Power of Attorney shall be
automatically revoked solely as to such individual, immediately upon such
cessation, without any further action on my part.
IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
executed as of the 17th day of June, 2013.
