I've also taken photos while the belt is still intact. Once the thing breaks it will be harder to follow the diagram in the manual and also on the tractor underside. That is literally the only thing I have not had to replace with my 8 year old Craftsman. Youtube and repairclinic.com videos have shown me how to fix things nearly every time. Thanks Sid. I'm going to copy/paste your answer for future reference. With my luck, it is bound to happen sometime soon.
