How to Replace a Shear Pin on a Two-Stage Snowblower

This article outlines the simple steps required to replace a shear pin on your two-stage snowblower. 
Shear pins are specifically designed to break before a more important part of your snowblower does. If you run over a chunk of ice, a rock, or some other debris, such as a newspaper, a shear pin will snap and prevent the auger and gear box from failing in the process. When this happens, you will need to replace the shear pin. 

Remember to always use shear pins designed for your snowblower to prevent an expensive auger or gear box failure. You can use's lawn equipment part finder to make sure you get the right part for your machine.
