It has always been my understanding that the M20 had a 1 1/4" PTO shaft size, which was an odd ball and took a special (much more expensive) PTO clutch. I've discovered the one I have that came out of a Cub Cadet 2082 originally has a 1 1/8" PTO shaft just like my M18 does. Are there some out there that were 1 1/8", or is mine an odd ball somehow with a non Cub Cadet engine/crankshaft in it? Or do I have an M18 masquerading with an M20 ID tag, and M20 decals on the engine tins?
