Cub Cadet Cub Cadet 3X 26 TRAC IntelliPOWER 357cc Three-Stage Snow Blower MECH-AUGER-STOPPED Error Fix: Auger Does Not Rotate When Engaged — Shear Pin or Belt

Error code MECH-AUGER-STOPPED on the Cub Cadet Cub Cadet 3X 26 TRAC IntelliPOWER 357cc Three-Stage Snow Blower means: Auger Does Not Rotate When Engaged — Shear Pin or Belt. The auger control lever is squeezed but the auger does not rotate. This is extremely common and is usually caused by broken shear pins. The shear pins are INTENTIONAL weak points designed to break and protect the gearbox if the auger hits a rock, ice chunk, or frozen newspaper. Two-stage (2X) models have auger shear pins on each side of the auger shaft. Three-stage (3X) models also have an accelerator shear bolt. Diagnosis: (1) SHEAR PINS — the most common cause by far. Look at the auger shaft ends where they connect to the driven housing. If the pin is broken, the auger shaft spins freely inside the auger. Replace with the correct Cub Cadet shear pin (NEVER use a standard bolt — a hardened bolt will transmit shock to the gearbox, causing expensive damage). Always carry spare shear pins. (2) AUGER BELT — the belt from the engine to the auger/impeller gearbox may be broken, worn, or thrown off the pulleys. Inspect the belt. Replace if damaged. (3) GEARBOX FAILURE — if shear pins are intact and the belt is good, the internal gears in the auger gearbox may have stripped. The gearbox must be replaced as a unit ($100-$200). (4) On 3X models: the accelerator (high-speed impeller) has its own shear bolt. If only the accelerator has stopped but the auger still turns, check the accelerator shear bolt.
