How to fix a snow blower auger that is not turning
Steven E / Tuesday March 18, 2025
When snow starts stacking up, your snow blower is a real game-changer. But what do you do when you pull the handle and the auger just sits there? Don’t let a stubborn auger throw a wrench in your plans. We’re here to help you figure out what’s going on so you can get back to clearing that snow in no time.
The info we’re sharing might not match your specific appliance. While we aim to provide helpful tips for all sorts of DIY repairs, different models can have variations in steps, error codes, parts, and so on. For the best guidance, it’s a good idea to check your manufacturer’s manual or give us a shout if you’ve got questions.
1. Worn or broken drive belt
The drive belt transfers power to the auger. Over time, it can wear out, stretch, or break, stopping the auger from turning.
How to fix it:
- Turn off the snow blower: Disconnect the spark plug and let the engine cool.
- Access the belt: Remove the belt cover near the engine.
- Inspect and replace: If the belt is worn or broken, slide it off the pulleys and install a new one, ensuring it’s seated correctly.
- Reassemble and test: Replace the cover, reconnect the spark plug, and start the snow blower to test the auger.

2. Damaged or missing shear pins
Shear pins are safety parts designed to break if the auger hits a hard object. If they’re broken or missing, the auger won’t turn.
How to fix it:
- Turn off the snow blower: Disconnect the spark plug and let the engine cool.
- Locate the pins: Inspect the auger shaft for broken or missing pins.
- Remove broken pieces: Use pliers to clear out any broken pin remnants.
- Install new pins: Align the holes, insert the new shear pin, and secure it with the provided fastener.
- Test the auger: Reconnect the spark plug, start the engine, and check if the auger rotates properly.
Pro Tip: Keep spare shear pins on hand to avoid delays during heavy snowfalls.
3. Clogged auger housing
Packed snow, ice, or debris in the auger housing can block the auger’s movement, preventing it from turning.
How to fix it:
- Turn off the snow blower: Disconnect the spark plug to ensure safety.
- Inspect the auger housing: Look for compacted snow or debris obstructing the auger.
- Clear the blockage: Use a clearing tool or a sturdy stick to remove packed snow and debris. Avoid using your hands to prevent injury.
- Test the auger: Reconnect the spark plug, start the engine, and ensure the auger rotates freely.
Pro Tip: Clear the auger housing regularly during heavy use to prevent clogs.
4. Faulty auger cable or lever
The auger cable connects the control lever to the auger system. If the cable is stretched, broken, or disconnected, the auger won’t engage when the lever is pressed.
How to fix it:
- Turn off the snow blower: Disconnect the spark plug and allow the machine to cool.
- Inspect the cable: Check for visible wear, breaks, or if the cable has come loose from its connections. Ensure the control lever is moving properly.
- Adjust or replace the cable: Tighten the cable adjustment screws if it’s loose. If damaged, disconnect the old cable, attach the new one, and secure it with the appropriate fasteners.
- Test the system: Reconnect the spark plug, start the engine, and operate the lever to ensure the auger engages smoothly.

5. Gearbox or transmission issues
The gearbox or transmission transfers power from the engine to the auger. If the gears are damaged, worn out, or improperly lubricated, the auger won’t turn even if other parts are functioning.
How to fix it:
- Turn off the snow blower: Disconnect the spark plug to prevent accidental starts.
- Inspect the gearbox: Check for visible damage, leaks, or unusual noises when attempting to engage the auger. Ensure the gearbox housing is intact and properly sealed.
- Check lubrication: Open the gearbox and inspect the gears. Add gear oil or grease as specified in your snow blower’s manual. If the gearbox is dry or leaking, replace the seals or damaged parts.
- Replace damaged parts: If gears are stripped or broken, replace them with compatible parts for your model. Reassemble the gearbox carefully, ensuring all parts are aligned.
- Test the auger: Reconnect the spark plug, start the engine, and engage the auger to confirm the gearbox is functioning properly.
