Cotter pin on auger broke. There are 3 augers on each side of gear box. The auger closest to gear box doesn't have a pin. How is this held in place since both the auger next to the gear box that doesn't take a pin and the next auger over that does take a pin are moving. Since the auger next to gear box is not attached to the next auger over and is moving freely does this mean that something else is wrong with the snowblower?
