                      NORWEST BANKS STATIONERY



February 28, 1995



Steve Lind, President
Top Air Manufacturing, Inc.
Highway 20
Parkersburg, IA 50665

Dear Steve:

Per our discussions, our bank is happy to provide you with the
following commitment which includes financing for your existing
term loan, the acquisition of the Clay Equipment assets, and a
revolving line of credit.  Two copies of this commitment letter are
included allowing you to accept the terms by signing where
indicated.

Terms for the proposed loans to Top Air Manufacturing, Inc. would
be as follows:

A1.    $1,500,000 term loan due 5 years from closing date, amortized
       over 10 years with monthly principal and interest payments.
       Priced at 1/2% over Norwest Bank's base rate, floating.  This
       would equate to a current rate of 9.5%.

       Collateral would be a blanket security agreement on all assets
       of Top Air Manufacturing to include assets purchased from Clay
       Equipment.  In addition, the loan would be secured by a first
       mortgage on the two parcels of real estate in Parkersburg
       currently used by Top Air for manufacturing and warehousing.

       The purpose of this loan is the refinancing of existing
       equipment debt owed to Norwest by Top Air Manufacturing, and
       refinancing of liabilities of Clay Equipment as part of the
       acquisition.

A2.    $500,000 term loan due 5/31/97.  A principal payment of
       $250,000 will be due on 5/31/96 with the balance due at
       maturity.  Interest collected monthly, priced at 1/2% over
       Norwest Bank's base rate, floating.  This equates to a current
       rate of 9.5%.

       The purpose of this loan is also to finance the Clay Equipment
       acquisition, specifically to cover the amount of the
       acquisition that will be repaid by condemnation proceeds Clay
       is to receive from the City of Cedar Falls.

A3.    $3,000,000 revolving line of credit due 10/1/95.  Interest
       payable monthly, priced at Norwest Bank Iowa's base rate,
       floating.  This equates to a current rate of 9.0%.

       Collateral will be a blanket security agreement on all assets
       of Top Air Manufacturing including assets purchased from Clay
       Equipment.

       Purpose is to fund inventory and accounts receivable.  A
       borrowing base would be utilized allowing borrowings no
       greater than the total of 50% of inventory and 75% of eligible
       accounts receivable.  Eligible accounts receivable are defined
       as those accounts with an aging of 90 days or less from due
       date.

       The three notes outlined above will be governed by a loan
       agreement which will include the following terms:

       A.   Minimum Working Capital.  The Borrower will maintain at
            all times an excess of current assets over current
            liabilities of not less than $1,750,000.

       B.   Minimum Tangible Net Worth.  The Borrower will maintain
            a tangible net worth of not less than $2,500,000 at
            fiscal year end.

       C.   Capital Expenditures.  The borrower will not make any
            expenditures for fixed or capital assets which would
            cause the aggregate of all such expenditures made by the
            Borrower to exceed $250,000 during any fiscal year of the
            borrower without written consent of Norwest Bank.
            Approval of the expenditures for the Clay acquisition is
            hereby given.

       D.   Current Ratio.  For fiscal year end May 31, 1995,
            Borrower will have a ratio of current assets to current
            liabilities not less than 1.9-1.  The Borrower will
            maintain after that date, a ratio of current assets to
            current liabilities not less than 2.0 to 1.0 at each FYE.

       E.   Leverage Ratio.  For fiscal year end May 31, 1995,
            Borrower will have a ratio of total liabilities to
            Tangible Net Worth of not greater than 1.3 to 1.0.  The
            Borrower will maintain after that date at all times a
            ratio of total liabilities to Tangible Net Worth of not
            greater than 1.25 to 1.0 at each FYE.

       F.   Cleanup Requirement.  For a period of 30 consecutive days
            each year, the Company will have no outstandings on the
            line of credit.

       G.   Financial Statements.  Monthly internally prepared
            balance sheet and income statement within 30 days of
            month end.  Annual audited statements prepared by a
            certified public accountant within 120 days of FYE.

       H.   All condemnation proceeds received by Clay/Top Air will
            be applied 100% to principal on first note A2 then note
            A1.  100% of the proceeds received from the sale of
            Parkersburg real estate will be applied in the same
            fashion.

       I.   Beginning May 31, 1997 and each year thereafter, the
            Company will be required to apply up to 50% of "free
            operating cash flow" to note A2 and then to note A1.  The
            annual maximum requirement for pay down will be the
            amount needed to bring the term debt to the equivalent of
            a seven year amortization assuming an original balance of
            $1,500,000.

            Free operating cash flow is defined as follows: Net cash
            from operating activities minus capital expenditures, per
            GAAP standards.

       J.   Borrower is to maintain all deposit accounts at Norwest
            Bank, Cedar Valley as part of this loan agreement.

Steve, I believe this commitment meets the financing needs of Top
Air Manufacturing and I hope you find it acceptable.  On behalf of
Norwest, thank you for your existing business and the opportunity
to provide additional financing to you.  I enjoy working with you
and look forward to your response.  Please call me with any
questions.

Sincerely,


/s/Cathy A. Rottinghaus
