I get about 5-10 min of good snow and they are junk. I inspected the belt when I engaged the auger and I noticed the small pulley attached to the main shaft that goes into the motor, is moving in and out slightly. Once the load is applied, it moves, I'd say an 1/8" ish. But Im not sure what else could be blowing the belts. I inspected the pulleys and they seem in good condition. Thoughts ?
