CUB CADET 490-501-C062 Drive Belt 42" Deck XT1 XT2 LX42 LT42 FAB C 954-05021

What It Is

The Cub Cadet 490-501-C062 is a factory-spec drive belt designed for 42-inch deck mowers in Cub Cadet’s XT1, XT2, LX42, and LT42 Enduro Series. It connects the engine pulley to the mower deck spindle pulleys, enabling blade rotation.

Fitment & Compatibility

Check your model number – This belt fits Cub Cadet XT1 (LT42, LE42), XT2 (LX42), and LT42 FAB C models with a 42-inch fabricated or stamped deck. It replaces OEM part 954-05021.
Measure before buying – The belt is 1/2 inch wide and 96.5 inches long. If your original belt is a different length or width, it won’t fit.
Deck type matters – Works with both stamped and fabricated 42-inch decks, but not with 46-inch or 54-inch decks.
Cross-compatibility – Also fits some John Deere D100/D110 series with 42-inch decks (verify belt length), but Cub Cadet recommends using only their OEM belt for warranty coverage.

Key Things to Buy

• Quality – OEM Cub Cadet belt with Kevlar cord construction. Holds up better than generic aftermarket belts under heavy grass or wet conditions.
• Installation – Moderate difficulty. You’ll need a socket wrench to release the deck tension pulley. No special tools required, but leaving the deck on the mower is easier than removing it.
• Common gotcha – The belt routing diagram on the deck sticker is sometimes faded. Snap a photo before removing the old belt. If missing, the belt goes around the engine pulley, then the two outer spindle pulleys, then the tensioner pulley on the left side.
• Wear indicators – Replace if you see cracking, fraying, or glazing. Also check the tensioner spring – a weak spring can cause premature belt wear even with a new belt.

Should You Buy It

If you own a Cub Cadet XT1, XT2, or LT42 with a 42-inch deck, this is the correct OEM replacement. It’s priced higher than generic belts but delivers longer life and exact fit. Avoid it if your deck is 46 inches or larger, or if you want a cheaper aftermarket option – but expect shorter lifespan.
