Forgot to add:I really recommend buying a Case belt for the PTO driven attachments. They are not standard 1/2 or 5/8 belts, they are 9/16" and wear much better than 'will fits' from local sources.
The site I provided has some dealers that contribute often and will ship the correct parts.
I don't profit from them, just a satisfied customer.

Online catalog and ordering.
