I have a craftsman lawn tractor model 91727641 and the blade won't turn. I can see the pully turning but the belt isn't. I assumed the belt was loose but I can't figure out how to tighten it. Can it be tightened or does it have to be replaced?

The idler pulley is the only tightening that a craftsman has.If the idler spring is still strong and the belt is behind this pulley and all all the blade quell pulley's,your belt is just strached and needs replacing.

Check the pulleys (all of them) to make sure they turn free & easy. If a bearing is siezed, the belt will slip on the pulleys. Pay close attention to the quill assy at the rear center of the deck. Make sure everything is smooth & free before putting a new belt on. Also check the blade brake system to be sure it's releasing. Good luck, Roger
