What It Is

This 954-05040 upper drive belt transfers power from the engine pulley to the mower deck or transmission on select MTD-built lawn tractors. It’s a 5/8-inch wide by 35-1/4-inch long belt, designed for models from Craftsman, Troy-Bilt, Cub Cadet, Yard Machines, and Huskee with 42-inch or 46-inch decks.

Fitment & Compatibility

Before buying, verify three things: (1) your original belt part number matches one of the replacements listed (754-05040, 954-0241, 954-0241A, 754-0241, or 754-0241A). (2) Measure your old belt’s length and width—this belt is 35-1/4 inches long and 5/8 inches wide. (3) Confirm your mower model uses a single-belt upper drive system; dual-belt setups or zero-turn mowers require a different belt. This belt fits most MTD Gold, Silver, and Select Series tractors from the late 1990s through 2010s, but double-check your owner’s manual or deck diagram.

Key Things to Know

• OEM vs aftermarket: This is a Cub Cadet OEM replacement, not a generic. It’s built to the same specs as the original—expect consistent fit and durability.
• Installation difficulty: Moderate. You’ll need to remove the belt guard, release tension from the idler pulley, and route the belt around the engine pulley and deck pulley. A belt installation tool or a long screwdriver helps.
• Common gotcha: If your mower is vibrating or the belt slips under load, the idler pulley or tension spring may be worn—replace those at the same time. Also, check that the belt isn’t twisted during installation.
• Quality: Users report 3-5 seasons of normal use before needing replacement, assuming proper tension and no debris damage.

Should You Buy It

If your MTD-built tractor needs a direct-fit upper drive belt and you want OEM reliability without hunting for the exact model in a parts store, this is a solid choice. It’s priced competitively against generics but comes with the fit guarantee of an original part. Best for DIY homeowners with a Craftsman, Cub Cadet, or Troy-Bilt lawn tractor from the 2000s.
