Craftsman DYS 4500 with snowblower attachment will not start?

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?
