754-04208 954-04208A 954-04208 Upper Drive Belt Craftsman Riding Lawn Mower Troy Bilt LTX1040 Cub Cadet MTD Deck Belt 5/8 x 41inch Kevlar Cord

What It Is

This is a replacement upper drive belt for select Craftsman, Troy-Bilt, Cub Cadet, and MTD riding mowers, specifically designed to transfer power from the engine pulley to the mower deck spindles. It fits models like the LTX1040 and similar lawn tractors with a 42-inch or 46-inch cutting deck.

Fitment & Compatibility

Before buying, verify your mower’s model number (not just the brand) and deck size. This belt measures 5/8 inch wide by 41 inches long with a Kevlar cord construction. It replaces OEM part numbers 754-04208, 954-04208A, and 954-04208. Common compatible models include Craftsman LT1000, LT2000, and GT5000 series; Troy-Bilt Super Bronco and Pony; Cub Cadet LTX1040, LTX1042, and XT1; and MTD Yard Machines/Yard Man tractors with 42-inch or 46-inch decks. Cross-reference your old belt’s part number and measure the length (center-to-center pulley distance) to confirm fit—aftermarket belts may vary slightly. Avoid using on zero-turn mowers or decks larger than 46 inches.

Key Things to Know

• Quality: Kevlar cord construction offers better durability and less stretch than standard rubber belts, reducing slip under load.
• Installation difficulty: Moderate—requires removing the mower deck or accessing the belt routing diagram under the seat or deck. Expect 20–40 minutes.
• Common gotchas: Check belt routing carefully; incorrect path causes premature wear or deck vibration. Also inspect the idler pulley and tensioner for wear before installing.
• Aftermarket note: This is an aftermarket belt, not OEM Cub Cadet, but reviews indicate it matches OEM specs closely for most users.

Should You Buy It

If you need a reliable, cost-effective replacement for a worn or broken upper drive belt on a compatible 42- or 46-inch deck riding mower, this Kevlar cord belt is a solid choice. It’s especially suitable for DIYers who want better durability than standard belts without paying OEM prices. Avoid it if you prefer factory parts for warranty or exact fit on less common models.
