Was you ever able to fix this? Mine never threw the belt, but if my wife or kids get into thick grass it stops the blades and smokes the belt. Once it smokes one time, the $90 belt is shot. I tried a $20 Gates belt, but it wouldn't even keep it on, but worked great for the first 2 hrs of mowing and wouldn't slip at all, then started throwing it off. I adjusted my tensioner by adding shims and tilting the pulley so the belt isn't at such an angle going onto the tensioner. This seemed to help, but didn't fix it completely. Right now I am back to a smoked original which stays on, but shakes like crazy. 1. is there a cheaper belt that actually works, and 2. has anyone adjusted the tensioner so it doesn't throw the belt or to stop a factory belt from slipping?
