Tractors are a great way to keep the yard clean. It can be trying at times replacing the belts. I did some research on www.managemylife.com. On page 25 of the owners manual there is information on replacing the belt. I am adding a link below for the manual to assist you. I hope this helps you out until your expert can answer your question.
The part number for the belt does not come up as a good number. Is this the long transmission belt, the short transmission belt, or the mower deck belt? You can reply back to me on this thread and I'll see if I can find directions to assist you with this procedure.
