I have acquired an older Kawasaki Mule 2010 with KAF 540C engine. The engine is shot so I have the option to either rebuild or replace. I am thinking a swap to a three cyl diesel out of a Toro mower. Anyone tried this? The only reason I am considering this is because I have the mower which is inoperable. The engine runs great so just wondering if this swap would be feasible?????
