UDC Parts 954-05022A Deck Belt Replacement for Cub Cadet XT1 LT46 XT2 LX46 XT2-LX46 KW 954-05022 754-05022A Craftsman T240 T2400 MTD Troy Bilt CMXGZAM501063 490-501-C063 / Aramid Cord / 108 inch

What It Is

This is an aftermarket replacement deck belt (108 inches, aramid cord construction) designed to transfer power from the engine pulley to the mower deck blades on select Cub Cadet, Craftsman, MTD, and Troy-Bilt lawn tractors with 46-inch cutting decks.

Fitment & Compatibility

Before buying, confirm your mower has a 46-inch deck (LT46, LX46, etc.). This belt replaces OEM part numbers 954-05022, 754-05022A, CMXGZAM501063, and 490-501-C063. It fits Cub Cadet XT1 LT46, XT2 LX46, XT2-LX46, Craftsman T240/T2400, and Troy-Bilt models using those OEM belts. Measure your existing belt length (should be 108 inches) and check the deck belt routing diagram for your specific model—routing varies between decks. This belt is not for 42-inch or 50-inch decks.

Key Things to Know

• Aramid cord vs. standard: Aramid (Kevlar-type) is stronger and resists stretching better than standard rubber belts, but it can be stiffer during installation.
• Installation difficulty: Moderate. You’ll need to remove the deck or at least the belt covers, and may need to loosen the tensioner pulley. Watch a model-specific routing video to avoid misrouting.
• Common gotcha: The belt may feel tight at first—rotate the pulleys by hand while seating it to ensure it’s fully in the grooves before engaging the tensioner.
• Lubrication: Do not use belt dressing or lubricant; it can cause slipping and premature wear.

Should You Buy It

If you own a Cub Cadet XT1/XT2 or compatible Craftsman/MTD with a 46-inch deck and need a durable, cost-effective replacement that outperforms standard rubber belts, this is a solid choice. Avoid it if you’re not comfortable with basic deck removal and belt routing—consider a pre-routed OEM belt for simpler swap.
