How does the auger work on a snowblower? The impeller is attached to the driveshaft with a shear pin. The end of the impeller shaft connects to the gearbox. The gearbox makes a 90 degree change in shaft direction so that the auger shaft can run across the width of the snowblower. Each auger is attached to the auger driveshaft with a shear pin.
