490-501-C062 Lawn Mower Drive Belt Fits for MTD Cub Cadet Craftsman 42" Deck XT1 XT2 LX42 LT42 LT42EFI LT42KH LX42KH 490-501-M062 (1/2" x 99-3/4")

What It Is

This is a replacement drive belt (1/2" wide x 99-3/4" long) for select MTD, Cub Cadet, and Craftsman lawn tractors with a 42-inch cutting deck. It transfers power from the engine pulley to the deck spindles, enabling blade rotation.

Fitment & Compatibility

Before buying, verify three things: deck size must be exactly 42 inches (measure blade tip to tip), belt length must be 99-3/4 inches, and belt width must be 1/2 inch. This belt fits MTD/Cub Cadet models including XT1, XT2, LX42, LT42, LT42EFI, LT42KH, LX42KH, and Craftsman equivalents (e.g., T110, T120, T130 with 42" decks). It replaces OEM part numbers 490-501-C062 and 490-501-M062. Not compatible with 46" or 50" decks, or zero-turn mowers. Check your owner’s manual or existing belt number before ordering.

Key Things to Know

• Quality: Aftermarket belt, not OEM Cub Cadet. Some users report shorter lifespan than OEM, but adequate for moderate use.
• Installation: Moderate difficulty—requires removing the deck or belt guard, routing around pulleys, and using a tensioner tool. A diagram or video helps.
• Gotcha: The belt may be slightly stiff out of the box; flex it a few times before installing to avoid binding.
• Gotcha: If your mower has a spring-loaded idler pulley, release tension slowly to avoid pinching fingers.

Should You Buy It

This is a solid budget-friendly option if you need a quick replacement for a 42" deck MTD/Cub Cadet/Craftsman tractor and don’t mind a slightly shorter lifespan than OEM. Best for light-to-moderate residential use; skip it for heavy commercial cutting or if you want maximum durability.
