Cub Cadet Cub Cadet XT1 LT42 IntelliPOWER 547cc 42" Riding Lawn Tractor MECH-VIBRATION Error Fix: Excessive Vibration During Operation

Error code MECH-VIBRATION on the Cub Cadet Cub Cadet XT1 LT42 IntelliPOWER 547cc 42" Riding Lawn Tractor means: Excessive Vibration During Operation. The riding mower vibrates abnormally, especially when blades are engaged. Causes: (1) BENT BLADE — the most common cause. Hit a rock or root? Remove and check on a flat surface. Replace if bent. (2) UNBALANCED BLADE — after sharpening, balance the blade. (3) LOOSE BLADE BOLT — check torque (35-50 ft-lbs). (4) WORN SPINDLE BEARING — grab each blade tip (engine OFF, gloves) and try to rock up and down. Movement means the bearing is worn. (5) ENGINE MOUNT BOLTS — check for looseness. (6) DAMAGED FLYWHEEL KEY — a partially sheared key causes engine vibration.
