POWER OF ATTORNEY
EX-24

I, Thomas Paulson, hereby authorize and designate each of,
Sheila B. Goulding, Kristin A. Stokes and Amy Seidel,
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 powers herein granted. I hereby acknowledge that the 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 Exchange Act.

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 attorneys-in-fact.

IN WITNESS WHEREOF, I have caused this Power of Attorney to be
duly executed as of this 11th day of January, 2021.
