Cub Cadet Cub Cadet XT1 LT42 IntelliPOWER 547cc 42" Riding Lawn Tractor MECH-BELT-WEAR Error Fix: Deck or Drive Belt Premature Wear or Breakage

Error code MECH-BELT-WEAR on the Cub Cadet Cub Cadet XT1 LT42 IntelliPOWER 547cc 42" Riding Lawn Tractor means: Deck or Drive Belt Premature Wear or Breakage. The mower deck belt or drive belt wears out frequently, breaks during operation, or comes off the pulleys. Causes: (1) MISALIGNED PULLEYS or belt guides — if pulleys are not in the same plane, the belt wears on one edge. Check alignment and adjust belt guides. (2) DEBRIS — grass, string, or wire wrapped around blade spindles creates drag and accelerates belt wear. (3) WRONG BELT SIZE — use the exact OEM belt specified for the model. (4) SEIZED IDLER or SPINDLE BEARING — a locked bearing causes the belt to slide and burn. Check all pulleys for free rotation. (5) BELT GUIDES BENT — the metal guides near each pulley keep the belt on track. Bent guides allow the belt to walk off. (6) NORMAL WEAR — deck belts typically last 100-200 hours. Replace at first sign of cracking, glazing, or fraying.
