Ladies and Gentlemen:

          We have acted as special  Federal tax counsel for CNH Equipment  Trust

and sale of Class A-1 Asset  Backed  Notes (the  "CLASS A-1  NOTES"),  Class A-2
Asset Backed  Notes (the "CLASS A-2  NOTES"),  Class A-3 Asset Backed Notes (the
"CLASS A-3  NOTES"),  Class A-4 Asset  Backed  Notes (the "CLASS A-4 NOTES") and
Class B Asset  Backed  Notes (the "CLASS B NOTES";  together  with the Class A-1
Notes,  the Class A-2 Notes,  the Class A-3 Notes and the Class A-4  Notes,  the
"NOTES"), to be issued pursuant to the Indenture, dated as of March 1, 2000 (the
"INDENTURE"),  between the Trust and Harris Trust and Savings Bank, as Indenture
Trustee.  Capitalized  terms not otherwise defined herein are used as defined in
the Sale and  Servicing  Agreement,  dated as of March 1,  2000  (the  "SALE AND
SERVICING  AGREEMENT"),  among  the  Trust,  as  Issuer,  CNH  Receivables  Inc.
("CNHR"),  as  Seller,  and Case  Credit  Corporation  ("CASE  CREDIT"),  as the
Servicer.

          In that connection, we have examined originals or copies, certified or
otherwise identified to our satisfaction,  of such documents,  corporate records
and  other  instruments  as we have  deemed  necessary  or  appropriate  for the
purposes of this opinion,  including:  (a) the  Prospectus,  dated March 6, 2000
(the  "PROSPECTUS"),  and the Prospectus  Supplement (to the Prospectus),  dated

          The opinion set forth in this letter is based on reasoning  from legal
principles  based on the relevant  provisions  of the  Internal  Revenue Code of
1986, as amended, the legislative history thereof, currently applicable Treasury
regulations,   judicial  decisions,   administrative   rulings  and  such  other
authorities as we have considered  relevant.  There can be no assurance that the
opinions  expressed below could not be  successfully  challenged by the Internal
Revenue Service,  or significantly  altered by legislative  changes,  changes in
administrative  positions  or  judicial  decisions,  any of which may be applied
retroactively with respect to the completed transactions.  Any such change could
render the affected provisions of this opinion inoperative.  No tax rulings will
be sought from the IRS with respect to any of the matters discussed herein.

          Based upon the  foregoing,  we hereby confirm that: (i) the statements
set  forth  in the  Prospectus  under  the  heading  "U.S.  Federal  Income  Tax
Consequences"  and in the Prospectus  Supplement  under the heading  "Summary of
Terms--Tax  Status" (to the extent relating to Federal income tax  consequences)
accurately reflect our opinion;  (ii) the statements set forth in the Prospectus
under the  heading  "Illinois  State  Tax  Consequences"  and in the  Prospectus
Supplement  under the  heading  "Summary  of  Terms--Tax  Status" (to the extent
relating to  Illinois  state  income tax  consequences)  accurately  reflect our
opinion;  and (iii) the statements set forth in the Prospectus under the heading
"ERISA  Considerations"  and in the  Prospectus  Supplement  under the  headings
"ERISA Considerations" and "Summary of Terms--ERISA  Considerations"  accurately
reflect our opinion.

                                             Very truly yours,


                                             /s/ MAYER, BROWN & PLATT
