954-05022A Mower Deck Belt for Cub Cadet XT1 LT46 XT2 LX46 954-05022 Craftsman T240 MTD Troy Bilt Super Bronco XP 46 490-501-C063 490-501-M063 / Aramid Cord / 108.3 inches

What It Is

This is a replacement mower deck belt, 108.3 inches long with aramid cord reinforcement, designed to drive the blades on 46-inch cutting decks for Cub Cadet XT1 LT46, XT2 LX46, Craftsman T240, MTD, and Troy-Bilt Super Bronco XP models.

Fitment & Compatibility

Before buying, verify three things: deck size must be exactly 46 inches (not 42 or 50), belt length must be 108.3 inches (measure your old belt if possible), and OEM part numbers – this replaces Cub Cadet 954-05022A, 954-05022, 490-501-C063, and 490-501-M063. It also fits some Craftsman T240 and Troy-Bilt Super Bronco XP 46-inch decks. Check your mower’s model number (stamped under seat or on frame) against the seller’s compatibility list. Aftermarket belts can vary slightly; if your deck uses a spring-tension idler, the aramid cord construction should handle it fine.

Key Things to Buy

• Quality: Aramid cord is stronger than standard rubber/fiber belts, resists stretching, and lasts longer under heavy use or hot conditions.
• Installation: Moderate difficulty. You’ll need to remove the deck (or access pulleys from underneath) and release the idler spring to loop the belt. A diagram helps – take a photo before removing the old belt.
• Common gotchas: Don’t overtighten the idler; aramid belts don’t need as much tension as rubber ones. If blades don’t engage or the belt squeals, double-check the belt path (easy to route wrong). Also, verify your deck has a single-belt system (most 46-inch Cub decks do).
• Measurement double-check: Measure your old belt end-to-end while flat – if it’s more than 1/4 inch off from 108.3 inches, this belt won’t fit.

Should You Buy It

If you own a Cub Cadet XT1/XT2, Craftsman T240, or similar MTD/Troy-Bilt 46-inch deck and need a durable, long-lasting replacement that’s stronger than a standard cheap belt, yes – this is a solid choice. It’s not for decks smaller than 46 inches or for zero-turn mowers. For the price, it’s a reliable upgrade over basic rubber belts.
