FAQs

This belt is designed for 42-inch deck riding lawn tractors manufactured by MTD, including Cub Cadet, Troy-Bilt, MTD, and Craftsman. It is compatible with Cub Cadet XT1 and XT2 Enduro Series 42-inch deck models, such as the LT42, LT42 EFI, LT42 KH, LX42, LX42 EFI, LX42 KH, and LX42 KW. It also fits specific Craftsman models including the T8000, T7800, and T210. Because fitment can vary by model year and deck configuration, please verify your tractor's model number and original belt number before ordering.
This belt replaces OEM part numbers 754-05021, 954-05021, 490-501-C062, and 490-501-M062. It also cross-references with 754-05021A and 954-05021A. While the 754- and 954- prefixes often refer to the same application, you should always confirm the part number against your specific mower model and deck size.
This part functions as the 42-inch mower deck belt and serves as the deck/PTO belt for specific 42-inch riding mower configurations. It is the primary belt used to drive the mower deck blades on compatible 42-inch tractors. To ensure you receive the correct part, compare your original belt number to the 954-05021 specification or its listed replacements.
Typical symptoms include the blades failing to engage properly, weak or uneven cutting performance, squealing noises when the deck is engaged, a burning rubber smell, visible cracking or fraying, glazing on the belt surface, or the belt repeatedly slipping off the pulleys. If the mower stops cutting while the engine continues to run normally, a stretched or broken deck belt is a frequent cause.
Replacing this belt on most 42-inch riding mowers is a moderate DIY task that typically takes between 30 and 90 minutes, depending on your access to the deck and experience level. Essential tools include a socket or wrench set, pliers, work gloves, and occasionally a deck removal tool or a breaker bar for managing spring-loaded idlers. We recommend taking a photo of the existing belt routing before removal to ensure correct installation.
Before installation, inspect the spindle pulleys, idler pulleys, belt keepers, tension spring, and the deck engagement system. Ensure that no pulleys are seized, wobbling, or damaging the belt. Clean any packed grass from the deck and verify that the belt guides are properly positioned. If a new belt fails prematurely, it is often due to a frozen pulley bearing, incorrect routing, a weak tensioner, or a damaged belt keeper.
Premature failure is most commonly caused by worn idler or spindle bearings, improper belt routing, operating the deck with debris packed around the pulleys, or impacts with stumps and roots. Normal stretching from heavy use is also a factor. Engaging the deck at high engine speeds repeatedly increases shock loads on the belt. If the old belt shows uneven wear on one edge, this often indicates pulley misalignment or a bent belt keeper.
