POWER OF ATTORNEY

	I, Mark J. Fleigle, hereby authorize and
designate each of Eric A. Blanchard, Heidi M. Hoard,
John S. Livingston, Amy C. Seidel and Sharon A. Stuckmayer,
signing singly, as my true and lawful attorney-in-fact to:

(1)	execute for and on my behalf, in my capacity as an
officer and/or director of Tennant Company (the "Company"),
Forms 3, 4 and 5 in accordance with Section 16(a) of the
Securities Exchange Act of 1934 (the "Exchange Act") and the
rules and regulations promulgated thereunder;

(2)	do and perform any and all acts for and on my
behalf which may be necessary or desirable to complete and
execute any such Form 3, 4 or 5 and timely file such form
with the Securities and Exchange Commission, any stock
exchange or similar authority, and the National Association
of Securities Dealers; 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 to my benefit, in my best interest,
or legally required of me, it being understood that the
statements executed by such attorney-in-fact on my behalf
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.

	I hereby further grant 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 I might or could do if personally present, with full power
of substitutes 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

foregoing attorneys-in-fact, in serving in such capacity at
my request, are not assuming, nor is the Company assuming,
any of my responsibilities to comply with Section 16 of the

	This Power of Attorney shall remain in full force
and effect until I am no longer required to file Forms 3, 4
and 5 with respect to my holdings of and transactions in
securities issued by the Company, unless earlier revoked by
me in a signed writing delivered to the foregoing

	IN WITNESS WHEREOF, I have caused this Power of
