started mower and ran about 1/2 hour, turned off PTO deck while mower running and it would not turn back on. I drove it back to the garage, tried it again and it started. I continued to mow, and when I reversed the mower, deck stopped (normal) and when I went forward, it did not start back up. I tried the switch several time not luck. I put it in the garage looked to see if anything was caught in the blades. When I went to start it back up, it would not turn over and I am not getting the display screen to turn on when I insert the key.
