John Deere F935 Mower, Front Mount Deck Category

Original Model: Yanmar (John Deere) 3TNE72

This engine was made to John Deere specs, and not all Yanmar engines will match up to this one. I believe our Yanmar that we have listed here will fit this machine as long as you change the flywheel, bell housing, and starter from your original engine. Some parts will need to be swapped from the old engine to new including the front drive pulley, cooling fan, fuel pump, thermostat housing, Exhaust manifold, and throttle bracket. You will need to add a 12" wire extension and use your old starter bracket. Notch the starter bracket to fit at bearing bolts. Cut the cooling fan shield at the bottom( fan sits a little lower with the new water pump).

Additional Info
The frames between the newer and older models are slightly different. The newer model has a stub shaft on the flywheel side to drive the mower deck. The older model drives off of the opposite end.
