Cogged Belt

If the snowblower auger won't turn the cogged belt might be broken or worn out. The cogged belt makes the connection between the engine and the auger, sometimes directly driving the auger and sometimes powering the auger through a gearbox. If the belt is worn out, misadjusted, or broken the auger won't turn. Cogged belts normally have to be replaced once every year or two depending on how much use the snowblower gets.

Shear Bolt and Nut

If the snowblower auger won't turn the shear bolt and nut may have failed. The shear bolt is a metal bolt that slides through the auger axle sleeve to lock it in place with the auger drive axle. If the auger hits a rock or other object, the shear bolt is designed to cut in half and fall out in order to protect the auger, gearbox and other components. If the auger won't turn, check to see if the shear bolt is in place and intact. If not, replace it.

Bearing

If the auger won't turn one or more of the bearings might have seized. Most bearings are permanently lubricated and don't require maintenance. If yours has a grease fitting, fresh grease should be added according to the manufacturers instructions. Once the bearing seizes it will have to be replaced. Sometimes the bearing can be freed up to work temporarily, but that fix is usually temporary.

Gearbox

If the snowblower auger won't turn the gearbox might have failed. The gearbox is located between the two halves of the auger. It has three shafts, one leading back to the drive system, and the other two at 90 degree angles to power the two halves of the auger. If the drive system is powering the main shaft and the sheer pins are good but the two auger shafts aren't rotating, the gearbox will need to be replaced.
