Ariens Path-Pro 208 208cc 28 in 2-Stage Gas Snow Blower with Electric Start MECH-SHEAR-PIN Error Fix: Broken Shear Pins

Error code MECH-SHEAR-PIN on the Ariens Path-Pro 208 208cc 28 in 2-Stage Gas Snow Blower with Electric Start means: Broken Shear Pins. Shear pins (or shear bolts) connect the auger blades to the auger shaft. They are designed to break (shear) when the auger hits a hard object like a rock, ice chunk, or newspaper, protecting the more expensive gearbox from damage. If the auger won't turn, shut off the engine and visually inspect both shear pins on the auger shaft. Replace broken shear pins with the correct Ariens replacement parts — never use regular bolts as substitutes, as they will not break when needed and can damage the gearbox.
