What It Is

This is a 1/2-inch wide by 108-inch long deck drive belt for 42- to 46-inch cutting decks on select Troy-Bilt, Cub Cadet, MTD, and Craftsman lawn tractors. It transfers power from the engine pulley to the spindle blades, and is a direct replacement for OEM part numbers 490-501-C063, 954-05022, and 754-05022A.

Fitment & Compatibility

Before buying, verify your machine’s deck size (46-inch decks are most common for this belt) and check your current belt’s length and width. This belt is specifically designed for Cub Cadet XT1 and XT2 Enduro Series models: LT46, LT46 KH, LX46, LX46 KW, T2800, T3100, T8200, T225, and T240. It also fits many Troy-Bilt, MTD, and Craftsman tractors with 46-inch fabricated or stamped decks using the same OEM numbers. Do not assume fitment based on brand alone—measure your old belt or cross-reference your model’s parts diagram. This is an aftermarket replacement, not OEM Cub Cadet, but matches the original specs.

Key Things to Know

• Quality: Made from EPDM rubber with polyester cord; generally durable for residential use but may wear faster than OEM under heavy, frequent mowing.
• Installation: Moderate difficulty—requires removing the deck or working under it, routing around idler pulleys, and tensioning correctly. A belt routing diagram is essential; take a photo before removing the old belt.
• Common gotchas: The belt can be tight to install; use a wrench to relieve tension on the idler pulley. Incorrect routing causes slipping or premature wear. Verify the belt is not twisted before running the mower.
• Lifespan: Expect 1-3 seasons depending on mowing conditions, deck cleanliness, and pulley alignment. Replace if you see fraying, cracking, or glazing.

Should You Buy It

If you own a compatible Cub Cadet XT1/XT2 or similar MTD-built tractor and need a budget-friendly replacement for a worn deck belt, this is a solid choice. It works well for typical residential mowing but may not last as long as a premium OEM belt under commercial or heavy use. Measure your old belt and confirm your model number before ordering.
