Snowblower Common Questions

These common questions about snowblowers are the ones our experts hear the most often from our customers. You might also find the help you need by checking the common symptoms and solutions for snowblowers. When you’re ready to make a repair, has the part you need, no matter where you bought your snowblower.


Why won't my auger turn?

A broken shear pin is the most common reason the auger won't turn. If the shear pin is broken, replace the shear pin. The shear pins are designed to break when a hard object becomes jammed in the auger to protect damaging the gear case or belt.

Other causes include a worn auger drive belt. Replace the auger belt if worn. A gear case failure or too much slack in the auger control cable could also be cause. Inspect the auger drive components and replace any worn or damaged parts.

Why won't my snowblower propel itself?

A worn or loose drive belt, friction disc or slack in the drive engagement cable can prevent the snowblower from moving. Inspect the drive belt and the friction wheel for wear. If the drive belt and friction wheel is not damaged or worn, adjust the drive control cable. If the friction disc is worn, replace the friction disc.

Can I use E85 (ethanol) fuel in my snowblower?

E85 is a fuel combination of ethyl alcohol (ethanol) and gasoline. It contains 85% ethanol. Many snowblowers are not designed or certified to use E85 fuel or any alcohol blended fuel.  Check your  your owner's manual your specific model.

Why is my snowblower difficult to start?

Water or dirt in the fuel system could cause the engine to be difficult to start. Stale fuel is also another cause. Remove the fuel from the fuel tank and add fresh gas. If the snowblower has fresh gas and it is still hard start, a fouled or burnt spark plug could be the reason. Remove and replace the spark plug.  If the snowblower has fresh gas and the spark plug is getting spark and won't start, it may need to have the carburetor cleaned and rebuilt.

What steps do I take to store my snowblower?

Never store your snow thrower with gasoline in the fuel tank indoors or in an enclosed, poorly ventilated area. If gasoline remains in the tank, fumes may reach an open flame, spark or pilot light from a furnace, water heater, clothes dryer, cigarette, etc. Gasoline must be removed or treated to prevent gum deposits from forming in the fuel tank, filter, hose, and carburetor during storage. It is best to run the engine until the fuel tank is empty and the engine stops before storing the snowblower.

If you do not remove the gasoline, use fuel stabilizer supplied with unit or purchase Craftsman Fuel Stabilizer. Add fuel stabilizer to any gasoline left in the tank to minimize gum deposits and acids. If the fuel tank is almost empty, mix stabilizer with fresh gasoline in a separate container and add some to the fuel tank.

Why won't my snowblower discharge snow?

A broken shear bolt connecting the auger to the shaft will prevent the auger from turning and pushing snow up into the impeller and discharge chute. If the auger drive belt is loose or worn, the belt will slip and prevent the auger from turning.  Replace the auger drive belt. Check the auger drive belt and adjust if needed. Follow the procedure in your owner's manual.

The auger control cable being out of adjustment could also prevent the auger from turning and discharging snow. This video shows how to adjust the auger control cable on a snowblower. A two-stage snowblower has an impeller to discharge snow as the auger pushes snow into impeller housing. If the impeller is not spinning, it could have a broken gear in the gear case. If the auger and impeller are spinning, check for a blockage in the discharge chute.

A broken shear pin connecting the auger to the shaft will prevent the auger from turning and pushing snow up into the impeller and discharge chute. Replace the shear pin if broken.
