I know a guy that put a small block V8 in a Craftsman yard tractor. As far as I can tell, the biggest difference is the exhaust note and the silly grin on his face. :D

I will say that more HP=less strain on the engine for the same amount of work. but there's no way the blades can spin fast enough to cut grass at 60MPH.. and bumps can be deadly at that speed, (no suspension)..

Sidetracking, re post #32, what is the speed rating on the R1 tyres on the tractor, and is the sped within the rating? They will fail at excessive speed.

They should be good up to 25 or 30 MPH intermittently.

I would think you'd have to beef up the front suspension and tires to handle the added weight of the engine. What about the frame for vibration or torque?

You’d probably have to completely scrap the the entire mower and start from scratch fabricating a frame and drive train. Maybe an old tough wheelhorse or something would take it. And after all that trouble what was the gain. If you really wanted the best mower engine but something with a Kubota diesel in it.

the one I linked to is a Massey Ferguson MF-350 which had a 50 HP engine originally, a regular lawn tractor just won't cut it without breaking something..
