I bought a used B21 that didnt come with the three point linkage. I would like to attach a post hole digger. Any idea where to find a set that would fit without spending $500 or more ? Does a another tractor model fit?
You should find out, through another owner or possibly a dealer, what the lengths are for the original equipment. There have been posts on here where the owner bought an aftermarket set, and things weren't proportional.
Here is a link to an aftermarket set on Ebay- http://www.ebay.com/itm/3-POINT-HIT...081?pt=LH_DefaultDomain_0&hash=item4d0546c601
