Shear Pin, .25 738-04124A

This individually sold shear pin is an OEM replacement that is most typically used in snowblowers but can also be used within snowblower attachments for lawn tractors. Its main uses are connecting the auger and auger shaft, which are the rotating blades, and to protect more valuable components such as the transmission.If the snow is causing excessive force or there is a jam within the auger and connected housing,it will cause the shear pin to snap, effectively stopping the rotation of the auger, while the auger shaft and gears will continue turning. If the shear pin snaps, snow will simply build up on the outside of the auger housing, since the auger will no longer spin. This shear pin has a .25-inch diameter, and 1.5-inch length and is sold individually. Most augers have a pin on each side, so you may need to purchase more than one, and it is also recommended that you carry spare pins in case of a future breakage.
