Rotary Shear Pin for Ariens

This shear pin acts as a safety mechanism for your snow blower. If your auger hits a solid object like a rock or ice chunk, the pin is designed to snap, which disconnects the auger from the gearbox to prevent expensive internal damage.

No, this specific pin is engineered for the Ariens 510015 model. Always verify your specific snow blower model number before purchasing to ensure the pin fits correctly and provides the intended safety protection.

This item is sold as a single pin. Because shear pins are designed to break under stress, it is highly recommended to keep a few spares on hand so you aren't stuck in the middle of a storm if one fails.

Never replace a shear pin with a standard bolt or hardware store fastener. Standard bolts are often too strong and will not break when they should, which can lead to catastrophic damage to your snow blower's gearbox or auger assembly.

If your snow blower engine is running but the auger blades stop spinning or seem to have lost power, your shear pin has likely snapped. You should immediately shut down the machine and inspect the auger shaft to confirm.
