My DYS 4500 will not start. I was plowing the driveway with the 42" blower attachment when it hit a large tree branch that was hidden in the snow. It jammed it solid, which caused it to start making a large noise with the effort of trying to break through the branch. I immediately stood up which caused the tractor to shut off. Problem being, once I cleared the jam and went to start it it will not even turn over.
I did Try to boost it just in case but that didn't work, belts are all fine. Not sure what else to try anyone have any ideas?

1st make sure the electric PTO button switch or PTO lever is in the OFF position. Next check the wiring harness under the seat & ensure it didn't come loose. The safety interlock system is not allowing it to crank. There is a clutch pedal switch, the seat switch and the PTO switch.
