Why Won't My Snow Blower Blow Snow?

Why Won't My Snow Blower Blow Snow? Posted in Snowblowers by Todd Myer

There are several things to consider when troubleshooting a snow blower that won't blow snow. Most manufacturers will tell you that if you are using your snow blower properly, the auger and chute shouldn't clog with snow. But if it does, follow these steps:

Lightly Clogged Auger or Chute

1) Stop the auger by releasing the auger control lever.

2) Push down on the operator handles to raise the auger housing slightly off the ground.

3) Gently tap the auger housing onto the ground in an attempt to dislodge the clogged snow.

4) Repeat this process until the clog has cleared.

Stubborn Clogs in the Auger or Chute

Release the auger control lever, turn off the engine, and wait for all moving parts to stop moving.

1) Disconnect Spark Plug Wire

Remove the spark plug wire to prevent an accidental startup.

2) Use Cleanout Tool

Use the cleanout tool to break up and remove the blockage. Never use your hands.

3) Reconnect the Spark Plug

Once you've cleared the clog, reconnect the spark plug.

Be sure the discharge chute is pointed in a safe direction before you restart the engine. When you engage the auger control lever again, this will clear the rest of the dislodged snow from the auger housing.

If you notice that the auger isn't engaging, there are a few things to check to identify this problem.

Auger isn't Engaging

If the auger is not turning, snow cannot be fed to the impeller to blow snow out the chute.

1) Check the Belt

Is the auger drive belt loose or slipping? If so, it may need to be replaced. Here is an article on how to replace snow blower belts.

2) Adjust Auger Control Linkage

If the belts look to be in working order, you may need to adjust the auger control linkage. The procedure for this differs from manufacturer to manufacturer, but there should be a way to change the tension on the spring that engages the auger switch.

3) Check Shear Pins

Take a look at the shear pins. Are they intact? Broken shear pins will prevent your auger from turning. Learn how to replace a shear pin.
