Rispondi a "only one drive wheel is spinning"You may have roasted the hydrostatic drive belt on that wheel
Rispondi a "mower deck will not engage when the PTO switch is turned on?"I had the same problem... I found one of the wires had rubbed of the plastic coating near the clutch and was grounding out. I put a shrink wrap tube on it and rerouted the wire from where it was rubbing. Haven't had a problem since.
