Need the Model number of the engine but yes Briggs has a 21 hp that will go on it but you will need a rewire kit to do it

My Father and I both bought these Cub Cadets from tractor supply 8 years ago. I bought the one with the 15 hp and his is the 17hp . Both the Kohler Command engines. Both around 350 hours on them and with the oil changed according to the manual both engines are shot. Now I cant seem to find the kohler replacement engine for these mowers. I would prefer Briggs and Stratton. Is there a Briggs engine that would work on the Cub Cadet 1515 mower?

You have two options for Briggs the 31C707 engine which is rated at 17.5 hp or the 331877 engine rated at 21hp.

I pulled the head off and was able to move the piston back and forth on the cylinder walls a strong 1/16" of an inch. Took the engine to a mechanic and he said it wasn't worth fixing. I just us the term shot as it is in not worth fixing. Or at least that's what the professionals are saying.

I was trying to find shaft length and diameter on the kohler online, but apparently I will have to drop the PTO to find that out. Does the shaft on the Briggs 31C707 engine have the same shaft size as the Kohler?
