I am looking for an operator's manual for a Craftsman LT 1000 Model Number 917275401.

Blades are not turning on my tractor. The front pully is turning but the belt is loose. Am looking for the Operator's Manual so I can troubleshoot.

You can go to sears .com and order one.
Probably the pto cable is not engaging the front pully on you deck,common problem on this model.
Luck

PS Craftsman riders have a bushing at the pivot of the engagement arm/idler that seizes and requires periodic cleaning.
