Correspondingly, how long do snowblower belts last?

about five to seven years

Subsequently, question is, why does my snowblower belt keep breaking? Check the pulleys for wear or bent places on a pulley. Check the bearings in the pulleys, if a bearing is seizing, it will throw the belt off or break it. An impact, bounce, or shifts to the pulleys, caused by uneven distribution of loads will hyperextend the belts maximum strength design.

Beside this, why does my snowblower not throw snow far?

A clogged chute won’t throw snow very far. If the chute isn’t clogged, check the augers and auger drive system. A damaged auger blade can‘t push snow through the shoot, and broken shear pins keep sections of the auger from spinning.

Why does my snowblower dies when Auger engaged?

I suspect there is something jamming the auger or the impeller. If you cannot turn the impeller check for ice built up around the impeller. If you find it is frozen up, you can free it with warm water. As soon as the impeller is free, start the engine and run the auger to clear it out.
