I have a Massey Ferguson 1260 with a 3 cyl Iseki turbo deisel engine. The engine has a cracked block from a hard impact with the bucket. I guess these tractors weren't made for many years and I'm having trouble finding a block or engine. I understand the MF 1260 is very similar to the Iseki TK538. Does anybody know if these engine blocks would swap out or where a person might find a block, blown engine or parts tractor?
