Today I was mowing the lawn, when the drive belt came off My Sears lt 4000 model # 917252600 lawn tractor. I removed the mower deck, what a pain that was. Well anyway the belt looks like its going to be even more of a pain to put back on. By the way this is the drive belt not the deck belt. New belts will be purchased before anything is done. Can you please help me with information or what is available on how to replace the belt? Thank you.
