I thought I would share an interesting occurrence. I was mowing when suddenly the tractor engine died and would not restart, not even a peep. A search of the electrical system revealed a blown fuse. I replaced it, and the tractor started, but it made a screeching noise and the fuse blew again. I went through the mower deck to make sure there was not a binding pulley, I replaced the belt to the deck (and it was in need of replacement), but I had not solved the problem. I removed the mower deck, and then I discovered the problem. I had driven one front wheel into a hole in my yard (two dogs who thought they heard someone in China and were going to dig their way to him), and the tie rod was badly bent. It was making contact with the drive pulley on the crankshaft. This was the cause of the screech and the blown fuses. If you encounter an "electrical" problem, add this item to your checklist.
