What It Is

This is a replacement deck belt for 46-inch cutting decks on select Cub Cadet, Craftsman, MTD, and Troy-Bilt lawn tractors. It drives the blades from the engine pulley and is specifically designed for models like the XT1 LT46, XT2 LX46, LX46 KW, Craftsman T240/T2400, and MTD/Troy-Bilt equivalents.

Fitment & Compatibility

Before buying, confirm two things:

• Deck size: Must be a 46-inch deck (not 42 or 50 inch).
• Belt dimensions: This belt is 1/2 inch wide x 108.3 inches long. Measure your old belt’s length and width if possible—slight variations can cause slipping or poor blade engagement.
• Cross-reference OEM numbers: 954-05022A, 490-501-C063, 490-501-M063, CMXGZAM501063. If your tractor’s manual lists any of these, it’s a direct fit.
• Not universal: Will not work on 42-inch or 54-inch decks, or on zero-turn mowers. Check your model number on the tractor’s frame tag.

Key Things to Know

• Quality: Aftermarket belt—generally reliable for residential use, but may wear faster than OEM under heavy commercial use.
• Installation: Moderate difficulty. You’ll need to remove the deck, route the belt around all pulleys (including tensioner), and reinstall. A diagram helps—take a photo before removing the old belt.
• Common gotcha: The tensioner pulley must be fully released to slip the belt on. If the belt feels too tight, you likely missed a pulley or the tensioner isn’t fully relaxed.
• No instructions included: Check your tractor’s manual or YouTube for routing specifics.

Should You Buy It

If you have a 46-inch Cub Cadet, Craftsman, MTD, or Troy-Bilt tractor listed in the compatibility and need a budget-friendly replacement for residential mowing, this belt is a solid choice. It’s not for commercial use or non-standard decks, but for routine replacement it offers good value.
