Gas Snowblower: Auger not turning
A broken shear pin is the most common reason the auger won't turn properly so replace any broken shear pins. Worn or loose belts also prevent the auger from spinning. Check and adjust the belts and replace any broken or worn belts. Check the auger drive cable and adjust it if loose or replace the cable if it's broken. Examine and replace the auger if it's damaged and won't spin. Replace the gear case if it won't spin the auger.
Our video on how to troubleshoot problems with the auger also can help you determine why your snowblower auger isn't turning.
Replace the snowblower 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
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
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
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
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
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.
You need a spark to fire up the engine of your snowblower, and that spark comes from a spark plug. You can replace one in minutes.
Replace the fuel line on your snowblower if it's cracked or damaged.
The shear pin breaks if you hit hard-packed snow, to protect the engine from damage. Your snowblower auger won't rotate until you fix it. You can replace it in about 10 minutes.
