Engine swap?

[broken sockets]

I have an old MTD tractor with the B&S opposed twin 17.5. Motor runs well, but the rest of the mower is falling apart.

Just had given to me a newer MTD (White branded) with a blown Intek 15.5 HP

What are the odds I can swap the twin from my MTD to the White without too much difficulty?

I am having trouble finding the specs and dimension on the Twin-II and I don't yet have the two machines in one place.

Any suggestions?

Mounting pattern will be then same. the main things will be the crankshaft diameter, and length. Will need to deal with the different exhaust. the wiring can be modified to work. If you mower has an electric clutch, Make sure the replacement engine has a large enough charging system.
