Installation Tips

  • Ensure the engine is off and the spark plug wire is disconnected before servicing.
  • Lower the mower deck to its lowest position to provide clearance.
  • Loosen or remove the belt guards as necessary to route the new belt through the pulleys.
  • Verify the belt is properly seated in all pulley grooves before tensioning.
  • Run the mower at low throttle for several minutes after installation to properly seat the belt.

FAQ

This belt is designed for 42-inch cutting decks on Cub Cadet ZT1-42, ZT1-42 Fab, and ZTS1-42 Fab models, as well as the Craftsman Z510 and Troy-Bilt Mustang Z42.
This belt replaces OEM numbers 754-06134, 954-06134, 754P06134, 490-501-C081, 490-501-M081, and CMXGZAM501081.
This is a 1/2-inch wide belt with an effective length of 117 inches.
You should inspect your belt if you notice uneven cutting, excessive vibration, the deck failing to engage, or if the belt shows visible signs of fraying, cracking, or glazing on the underside. If the mower loses blade speed under load or you hear a squealing noise when engaging the PTO, the belt has likely stretched or lost its tension.
Before installing the new belt, inspect your deck pulleys and idler arms. Ensure the pulleys spin freely without grinding or side-to-side play. If the idler pulley is seized or the spring has lost its tension, the new belt will wear out prematurely. It is also a good time to clean out any grass clippings or debris trapped around the spindle covers.
