ne 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. This snowblower is made by MTD Yard Machines
