Snowblower: Auger not turning

A broken shear pin is the most common reason the auger won't turn properly. Other causes include a worn auger drive belt or a gearcase failure. Inspect the auger drive components and replace any worn or damaged parts.

These repairs may help solve your Snowblower problem:

Replace the snowblower shear pin

Shear pin

Shear pins fasten the augers to their drive shaft. They're designed to break if the auger hits a large foreign object or hard-packed snow, to protect the motor and transmission from damage.The auger won't turn if the shear pin isn't intact, so replace it if it breaks.

Adjust or replace the snowblower belts

Auger belt

A worn or loose belt can slip or squeal when the snowblower is in use. Physically examine the belt and pulleys. If the belt is worn, replace it. If the belt is sound, adjust the pulleys to tighten the belt.

Replace the snowblower auger drive cable

Auger drive cable

The auger drive cable is a control cable that connects the auger control lever on the control panel to the engagement lever in the auger drive system. When the auger won’t engage, the cause is often a damaged, worn, or broken auger drive cable. Inspect the cable and replace it if it's worn or damaged.

Adjust the snowblower auger drive cable

Auger drive cable

If the auger doesn't stop when you release the control lever, the auger drive cable is too tight. If the auger doesn't rotate when you engage the control lever, there's too much slack in the auger drive cable. In both cases, adjust the auger drive cable so it starts and stop the auger correctly.

Replace the snowblower auger

Auger

Hitting rocks or other foreign objects hidden beneath the snow damages the auger. Broken or bent auger blades won't move snow into the impeller and out through the discharge chute. Replace the auger blades if damaged after hitting a large object that breaks the shear pins. Inspect the auger blades regularly and replace the auger if you find bent or damaged auger blades.

Replace the snowblower gearcase assembly

Gearbox assembly

The auger drive system uses a gearcase to rotate the auger shaft so that the augers can move snow. Replace the gearcase if the auger won't spin properly or at all.
