Watch our video on how to replace the drive belt on a Husqvarna ST121E single stage snow blower. The drive belt engages the auger paddles, allowing them to rapidly spin and throw snow out of the discharge chute. If the belt begins to show signs of cracking, or it breaks while operating, replace it immediately. You don't wont to get stuck in the next snow storm with a snowblower that won't clear snow.
