Laser Shear Pins are designed to break in half if your snow blower strikes a hard object. If the shear pin is broken your snow blower won't turn which prevents damage to the transmission and engine. For peace of mind, stock up for the season. Laser shear pins come in packages of 4 and includes all hardware.
