Replacing drive belt

Craftsman YS4500 model 917.28734 Lawn tractor runs great, no sputters, but when i go up even the slightest incline in my yard, the mower loses power. Thought it was a fuel problem despite the engine never missing a beat. Cleaned to carb, replace fuel filter, still doing it. I found that if i disengage the gas pedal and reengage then it will go. Could this be the drive belt slipping? If so, is there a manual explaining the procedure for doing so?

There can be many possibilities as to why you may be loosing power on your lawn tractor. I researched your question and found someone had the same question about their lawn tractor. On the expert answer it does say the drive belt could be a possible issue so I have also provided you with the instructions like you requested. I hope this helps!
