This is not a difficult fix. Stand the machine up on it's snout so the handles are facing straight up in the air. Remove the belt cover and the belly pan. Now you can install the belt. Slide the belt through the belly up to the engine. Route the belt around the auger pulley first, and then around the engine pulley. There are time when it is easier if you remove the idler pulley so you have a little more room to work. That is really all there is to replacing this belt. Just check the tension on it before you button everything back up.
