Hello. I am having a problem with my Husky GT going through Drive Belts. I can only get 8-10 acres worth of mowing and the belts are ruined. The mower is a 24 HP, 54" deck. The mechanics I have talked to gave me some things to check and I have done so. I have made sure there is no rubbing on the guides but the pulleys don't look so good. the idler pulleys are wider than the belt and don't spin freely. The motor pulley is a little warped. I can change the idler pulleys easily. How should I go about getting the motor pulley off? anyone out there have experience? Thanks for any help.
