If the auger hits a hard object, the shear pin breaks to prevent the transmission and engine from being damaged. The auger will not turn if the shear pin is broken.

After searching for he pins, Jack's had them and the price was great ! They arrived quickly and I am very pleased.

Thought this was what I needed but have to do more work to verify that it fits as needed. The original Sheer Pins were rusted in the shaft and have to be tapped out before I can use them. Otherwise, the service was great and I plan to use Jack's again in the future for stuff like this. Thank you!
