917.28934 I have a Craftsman YT3000. Used it the other day with no problem. Now, I have no forward or reverse. Looked underneath and the belt is not tight enough. It's super loose. I can pull it away from the pulley almost 2 inches. It's routed through the idlers correctly. The only movable idler I see, has a very short throw. Can't see how it puts any noticeable tension on the belt. Puzzling that I was driving it around all morning the other day and now this. Anyone come across this before? Should that idler with the big spring move more than a 1/4"? Maybe I can simply put a shorter belt on?
