Huthbrother Shear Pin and Cotter Pin

These pins are designed to fit most two-stage and three-stage snow blowers from major brands including MTD, Craftsman, Cub Cadet, and Troy-Bilt. However, because fitment varies by specific model year, we recommend verifying that your machine requires a 0.25-inch diameter pin with a 1.5-inch length before purchasing.

Shear pins are engineered to be the 'weak link' in your snow blower's drivetrain. If your auger hits a rock or ice chunk, the pin is designed to snap, protecting your expensive gearbox from catastrophic damage; a standard bolt is too strong and will transfer that impact force directly into the gearbox.

This kit contains a total of 20 pieces, which includes both the shear pins and the matching cotter pins needed for installation. It is a smart idea to keep the entire pack in your garage, as you will inevitably lose or break a few during a heavy winter season.

Yes, these pins are constructed from steel with a rust-resistant finish. This coating is essential for snow removal equipment, as it prevents the pins from seizing inside the auger shaft due to corrosion, which makes them much easier to remove when they eventually need to be replaced.

You generally do not need specialized tools, but a pair of needle-nose pliers is highly recommended for bending the cotter pins into place. Having a small hammer or a punch tool on hand can also be helpful if you need to tap out a broken pin fragment from the shaft.
