Cub Cadet Cub Cadet 3X 26 TRAC IntelliPOWER 357cc Three-Stage Snow Blower MECH-VIBRATION Error Fix: Excessive Vibration During Operation

Error code MECH-VIBRATION on the Cub Cadet Cub Cadet 3X 26 TRAC IntelliPOWER 357cc Three-Stage Snow Blower means: Excessive Vibration During Operation. The snow blower vibrates abnormally during operation. Some vibration is inherent in snow blower design, but excessive vibration indicates a problem. Causes: (1) DAMAGED AUGER — a bent or cracked auger creates imbalance. If the machine hit a hard object (rock, frozen pipe, ice block), the auger may be bent. Inspect visually and replace if bent. (2) LOOSE HARDWARE — the auger housing, handlebars, and engine mounting bolts loosen from vibration over time. Check and tighten all fasteners at the beginning of each season. (3) WORN AUGER BEARINGS — the bearings supporting the auger shaft wear over time. Worn bearings create play that causes vibration and noise. Replace the bearings. (4) IMPELLER DAMAGE — a damaged or unbalanced impeller vibrates at high speed. (5) ENGINE MOUNT BOLTS — loose engine mounting allows the engine to shift, creating vibration. (6) Check that no foreign objects (ice, gravel, debris) are lodged between the auger and housing.
