Snowblower: Won't throw snow far enough

If your snowblower isn't clearing pavement well, first turn off the snowblower and clear any snow that’s built up in the chute. A clogged chute can’t blow snow far.

If the chute isn't clogged, check the augers and auger drive system. A damaged auger blade can’t push snow through the shoot, and broken shear pins keep sections of the auger from spinning. A worn, stretched auger belt won't spin the auger fast enough to throw snow off the pavement, so replace the auger belt if it’s worn. If the belt is okay but the cable isn't keeping the belt snug on the pulleys, adjust the auger drive cable. A defective gearcase can also prevent the augers from spinning at the right speed, so replace the gearcase if it's defective.

If you didn't tune up the snowblower at the start of the season, the engine might be running rough and lack the power to throw snow. And if the chute doesn't pivot, you could end up blowing snow into the wind—and right back onto the driveway. If needed, replace control system components.

These repairs may help solve your Snowblower problem:

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.

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.

Do a snowblower tune-up

Spark plug

A tune-up restores the snowblower to its peak operating condition. A tune-up includes changing the oil, cleaning the engine, replacing the air filter, checking the ignition system, inspecting the carburetor, testing the battery, adjusting the throttle and choke controls, and adjusting and lubricating all moving parts.

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 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.

Clear the snowblower chute and housing

Chute

Snow and ice can build up inside the chute and housing, restricting the exit path of the snow being cleared. Shut off the snowblower and clear built-up ice and snow.

Replace the snowblower 4-way chute control assembly

Chute control

When you move the snowblower joystick on the snowblower 4-way chute control assembly, the joystick turns the snowblower chute rod, which then rotates the snowblower chute control gearbox. Replace the snowblower 4-way chute control assembly if it won't rotate the snowblower chute rod.

For manuals, repair guides, and specific part recommendations, enter your model number.

Replace the snowblower chute control gearbox

Chute control gearbox

The snowblower chute gearbox moves the discharge chute left or right as the joystick rotates the chute rod. If the chute control gearbox is damaged or stripped and the discharge chute won’t move, replace the snowblower chute gearbox.

Adjust or replace the snowblower chute deflector cable

Chute deflector cable

Examine the chute deflector cable if the chute defector isn't moving properly. Sometimes the cable just needs to be adjusted. But if the chute deflector cable is damaged or broken, replace it.

Repair the snowblower chute control assembly

Chute worm gear

Examine the chute control assembly for the cause of a problem with this component. The owner's manual usually shows how to properly assemble and adjust the chute control assembly. Replace the chute control assembly if it's damaged or defective.
