How do I tell when the mower will not go in gear if it's the Transmission or another problem, when it quit working I found the belt was off, I put the belt back on it still doesn't work. Murray 10.5hp 30in cut model # 309008x92A.

Hi,
Attached is the parts picture of the belt and drive system. You did not happen to take on or both rear wheels while working on the belt. They are anchored ot the axles by keys. No key and the axle spins inside the wheel.
Peace,
Clarke

No Clark I did not take off either back wheel nor did I have them off the ground Thanks for diagram.
