FAQ

This belt fits many 50-inch deck riding mowers from Cub Cadet, MTD, Troy-Bilt, Craftsman, and various Toro applications. Compatible models include Cub Cadet LT1050, XT1-LT50, XT1-GT50, XT2-LX50, XT2-SLX50, XT2-GX50, SLT1550, SLTX1050, LTX1050KH, LTX1050KW, LGT1050, LGTX1050, and i1050. To ensure a correct fit, verify your mower has a 50-inch deck and confirm the part number matches your original belt.
This belt replaces OEM part numbers 954-04077A, 954-04077, 754-04077, and 754-04077A. It also serves as a direct replacement for Toro part 112-0332, as well as CMXGZAM501021 and OCC-754-04077. We recommend matching this number against your old belt or your mower's official parts list.
Typical symptoms include blades failing to engage properly, weak or uneven cutting, squealing noises when the PTO is engaged, a burning rubber smell, visible cracking or frayed edges, belt glazing, or the belt repeatedly slipping off the pulleys. On 50-inch decks, a stretched belt often results in poor blade speed even when the engine is running at full power.
For most riding mowers, this is a moderate repair that typically takes 30 to 90 minutes, depending on your ability to access the deck. You may find it easier to remove the deck from the tractor entirely. Essential tools include work gloves, a socket or wrench set, pliers for deck pins or retainers, and potentially a breaker bar to manage spring tension. We recommend taking a photo of the belt routing before removal to ensure correct installation.
Before fitting the new belt, inspect the idler pulleys, spindle pulleys, belt keepers, tension spring, and deck bearings. A worn idler pulley, bent belt guide, seized spindle, or weak spring can cause premature belt failure. Additionally, clear any packed grass from the deck and verify the belt is routed according to your mower's specific 50-inch deck diagram.
Common causes include normal wear, overheating due to slippage, incorrect installation, insufficient tension, rough or frozen pulleys, and debris buildup under the deck. Impact with branches or heavy, wet grass can also twist or burn the belt. If your previous belt failed suddenly, inspect the pulley alignment and spindle condition to ensure the new belt does not wear out prematurely.
