FAQs

This belt is designed for 54-inch decks on various Cub Cadet, Troy-Bilt, and Craftsman lawn tractors. It is specifically compatible with Cub Cadet Enduro Series models, including the XT1 and XT2 lines (LT54, GT54, LX54, GX54, ST54, and SLX54), as well as Craftsman models such as the T310, T8400, T3200, G8400, and G8600.
This belt replaces and cross-references with several part numbers, including 754-05025, 754-05025A, 954-05025, CMXGZAM501064, and 490-501-C064.
This is a B-section V-belt with an effective length of 139 inches and a top width of approximately 0.656 inches.
You should inspect your belt if you notice uneven cutting, excessive vibration, or a burning rubber smell while the mower is running. Visually, look for signs of dry rot, cracking, fraying along the edges, or 'glazing' on the underside, which indicates the belt has been slipping and overheating.
Before installing the new belt, inspect all deck pulleys and the spindle bearings. Ensure the pulleys spin freely without grinding or wobbling. If a pulley is seized or damaged, it will cause your new belt to fail prematurely. It is also a good time to clean out any packed grass or debris from the deck housing to ensure proper airflow and belt seating.
Replacing the belt is a standard maintenance task that can typically be completed in 30 to 60 minutes. While the process varies slightly by model, you will generally need to lower the deck to its lowest position, remove the belt covers, and release the tension from the idler pulley to slide the old belt off. Having a socket set and a sturdy pry bar or a belt tension tool on hand will make the process significantly easier.
