My 1538 Hydro (model lt150h38lbv) keeps breaking deck belts after about 1 hours running. My last snapper belt lasted 45 minutes! Last use belt started to smoke at the front and then jumped engine pulley. I routed it over the belt guards instead of between them and engine pulley and this seemed to help. In deck position 1 thru 4 blades turn but in position 5 and 6 blades are getting no power. I replaced the engine 2 years ago with a "drop in" 17hp Briggs and I hate to not keep it just because it loves belts for lunch!! Any ideas greatly appreciated.......Greg
Belts smoke because they are running on something that does not move, like a frozen pulley or because something is rubbing on it ( engine pulley )
Once you get burning on the belt that section is thin & will jump off the pulleys the first chance.
If the blades do not spin at a particular deck height then either the tensioner is not working properly or the belt is too long or it is routed wrong.
