FAQ

This belt is used as a lower transmission / lower drive belt on select riding mowers from MTD-family brands, including MTD, Troy-Bilt, Craftsman, Cub Cadet, Huskee, Yard-Man, Yard Machines, Snapper, and Bolens. Commonly listed applications include Troy-Bilt Pony, Pony 42T, Pony 36T, Pony 42X, Tuffy, TB42 7-Speed, Craftsman T110, T85, T100, T105, T1000, T2700, and Huskee LT4200. Fitment can vary by exact model number and build code, even within the same mower name, so match your model number and original belt part number before ordering.
Known replacement and cross-reference numbers for this belt include 954-04249A, 754-04249, 954-04249, 754-04249A, CMXGZAM501006, 490-501-M006, and 490-501-Y006.
This lower drive belt is commonly listed at about 70.9 inches long, with many sources rounding it to 70.75 or 71 inches. The top width is typically listed around 5/8 inch to 0.656 inch. Small rounding differences in listings are common, but the critical check is the mower's original part number and model compatibility.
Typical signs include the mower not moving or barely moving in forward or reverse, slipping under load, jerky engagement, loss of ground speed on hills, or a belt that squeals, looks glazed, cracked, frayed, or stretched. If the engine runs and the blades may still work but the tractor drive is weak or gone, the lower transmission belt is a common item to inspect.
On most 42-inch riding mowers in this family, installation is a moderate repair. Plan on roughly 45 to 90 minutes depending on model and rust level. Typical tools include socket wrenches, a ratchet with extensions, pliers, and possibly a breaker bar for idler spring tension. Many models require lowering or removing the deck for access, and some may require removing belt guards or access panels near the transmission pulley.
Inspect the idler pulleys, tension spring, belt keepers, transmission pulley, engine pulley, and belt routing. A new belt can fail early if a pulley bearing is seized, a keeper is bent, or the tensioner is weak. Also clean packed grass and debris from the belt path, since buildup can cause heat and premature wear.
The most common causes are normal wear, heat glazing, slipping from weak tension, pulley misalignment, seized idlers, and debris packed around the belt path. On riding mowers, drive belts also wear faster when the tractor is used on hills, for towing, or with frequent stop-and-go direction changes. If the old belt came off shredded or heavily glazed, it's smart to look for an underlying pulley or tension problem before fitting the replacement.
