Why are the blades not spinning on my snowblower?

When it’s safe, visually inspect the augers. If you don’t see the shear pin head or nut and you can manually spin the auger along the auger shaft, you broke a shear pin.
Why does my snowblower keep dying?
A clogged carburetor is most commonly caused by leaving fuel in the snowblower for a long period of time. If the fuel cap vent is clogged, air won’t be able to enter the tank and a vacuum or “vapor lock” will occur. This stops the flow of fuel to the carburetor causing the engine to stall.
Should my snowblower auger spin freely?
You may have broken a sheer pin. Most two stage snowblowers have two auger blades, each pushes snow into the middle. If your auger is spinning freely, the shear pins have sheared or they have fallen out.
How tight should a shear bolt be?
It should be a locking type nut and all you need to do is snug it down to where it contacts the auger sleeve and stop there. Don’t snug it down to where the spindle turns with the shaft. If you do you’ll defeat the purpose of the shear pin.
How tight should snowblower shear pins be?

Why are the blades on my snow blower not turning?
One of the augers (snow chewing blades) on my snow thrower was not moving. So it was pushing more snow than it was throwing. After stopping it, I found a bolt that locks the auger to the rotating axle was missing. It is a shear bolt, so likely the bolt sheared off at some point. I show how to replace the shear bolt.
What causes a snowblower auger to not turn?
In both cases, adjust the auger drive cable so it starts and stop the auger correctly. 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.
