FAQ

This belt is used on certain 50-inch deck lawn tractors from Cub Cadet, MTD, and Craftsman. Confirmed Cub Cadet applications include LTX1050, LTX1050VT, SLTX1050, LTX1050KW, and LTX1050KH. The safest way to confirm fit is to match your mower's model number and deck size, then verify that it uses belt part number 754-04240, 954-04240, or OCC-754-04240.
Known cross-reference numbers for this deck belt include 754-04240, 954-04240, 75404240, 95404240, OCC-754-04240, and Toro 86-1960. Always match both the part number and your mower's 50-inch deck application before ordering.
Common symptoms include the blades not engaging properly, weak or uneven cutting, belt squealing, a burning rubber smell, visible cracking or fraying, or the belt jumping off the pulleys. On a 50-inch deck, a stretched belt can also cause poor blade speed even if the PTO still engages.
This belt is listed at approximately 162.9 inches long and 0.5 inch wide. Some listings round the length to 162 inches, but the common application reference for this part family is about 162.9 inches.
For most Cub Cadet, MTD, and Craftsman 50-inch deck tractors using this belt, installation is a moderate repair. Typical tools are a socket set or wrench set, work gloves, and possibly pliers for deck pins or guards. Expect about 30 to 90 minutes depending on whether you remove the deck fully for access. Take a photo of the old belt routing before removal, since incorrect routing is a common cause of immediate belt failure or poor blade operation.
The most common causes are normal wear, pulley misalignment, seized or rough spindle bearings, weak idler pulleys, debris buildup under the deck, and hitting heavy grass repeatedly with the blades engaged. If a new belt burns, twists, or comes off quickly, inspect the idler pulleys, spindle bearings, belt keepers, and deck routing before assuming the belt itself is the problem.
Inspect all deck pulleys for wobble, make sure the idler arm moves freely, check the tension spring, and spin each blade spindle by hand to feel for rough bearings. Also clean packed grass from the deck and confirm the belt guards are not bent into the belt path. Installing a new belt on worn pulleys or a dragging spindle can shorten belt life significantly.
