FAQ

This belt fits select lawn tractors, riding mowers, and garden tractors that use the upper transmission/upper drive belt in this size and part-number family. Brands mentioned for this belt include MTD, Troy-Bilt, Craftsman, Cub Cadet, Yard Machines, Huskee, Bolens, Yard Man, MTD Gold, and White Outdoor. Compatibility is model-specific, so the safest match is to confirm your mower's original belt number or model lookup before ordering.
This belt is associated with these replacement and cross-reference numbers: 954-05040, 754-05040, 954-0241, 954-0241A, 754-0241, 754-0241A, 954-04057, CMXGZAM501087, OEM-754-0241, and OEM-754-0241A.
The listed size for this upper drive belt is 5/8 inch x 35-1/4 inch. Additional references describe it as approximately 35.25 inches long with a top width around 0.656 inch. It is used as an upper transmission/upper drive belt rather than a mower deck blade belt.
Typical symptoms include weak or no tractor movement, slipping during acceleration or on hills, inconsistent ground speed, burning rubber smell, belt squeal, or visible cracking, glazing, fraying, or stretching. If the engine runs normally but the tractor does not drive correctly, the upper transmission belt is one of the first parts to inspect.
Replacement is usually a moderate repair because the belt is part of the drive system, not the cutting deck. On many MTD-family riders, access may require lowering or removing the mower deck and working around belt keepers, idlers, and transmission pulleys. Common tools are socket wrenches, pliers, and possibly a breaker bar for tension relief. A typical DIY repair can take about 45 to 90 minutes depending on the model and how much disassembly is required.
Inspect the idler pulleys, pulley grooves, belt guides, clutch/brake linkage, and tension spring before installation. A new belt can fail early if an idler bearing is seized, a pulley is bent, or a keeper is out of position. It also helps to clean debris from the drive area and compare the old belt routing to the factory routing diagram for your exact tractor model.
The most common causes are normal wear, heat buildup from slipping, weak belt tension, misaligned pulleys, seized idlers, and debris packed into the drive system. Oil contamination can also shorten belt life. If a replacement belt wears out quickly, the root cause is often elsewhere in the drive system rather than the belt alone.
