What It Is

This is a 108-inch by 1/2-inch aramid cord replacement deck belt, designed to drive the mower blades on select Cub Cadet XT1, XT2, Craftsman T240, MTD, and Troy-Bilt lawn tractors with 46-inch cutting decks. It’s a direct replacement for OEM part numbers 954-05022A, 954-05022, 754-05022, and 954-05087.

Fitment & Compatibility

Before buying, confirm three things: your deck size must be 46 inches (not 42 or 50), your belt length must be exactly 108 inches (measure your old belt end-to-end), and your belt width must be 1/2 inch. This belt fits Cub Cadet XT1 LT46, XT2 LX46, and Craftsman T240 with 46-inch decks, plus MTD and Troy-Bilt models using the same OEM numbers (CMXGZAM501063, 490-501-C063, 490-501-M063). It is an aftermarket replacement—not OEM—so check that your original belt part number matches one of the listed OEM numbers. If your deck uses a different belt length or width (e.g., 105-inch or 5/8-inch), this will not work.

Key Things to Know

• Aramid cord construction is stronger than standard rubber belts, offering better heat and wear resistance, which means longer life under heavy use.
• Installation is moderate difficulty—you’ll need to remove the deck or at least the pulley covers, and route the belt around all three spindle pulleys and the tensioner. A diagram is recommended.
• Common gotcha: the belt may feel tight initially. It will stretch slightly after a few hours of use, so don’t force it—use the tensioner to relieve slack.
• Price vs. OEM: at ~$20, this is about half the cost of a genuine Cub Cadet belt, but some users report slightly shorter lifespan (1–2 seasons vs. 2–3 for OEM). For occasional mowing, it’s a solid value.

Should You Buy It

If you need a reliable, budget-friendly replacement for a 46-inch deck on a Cub Cadet XT1, XT2, Craftsman T240, or compatible MTD/Troy-Bilt, this belt works well. It’s best for homeowners who mow weekly and want to save money without sacrificing basic durability. If you mow commercially or want maximum longevity, consider the OEM belt instead.
