What It Is

This is a 5/8-inch wide, 35.25-inch long aramid-reinforced V-belt that drives the mower deck blades on select MTD, Cub Cadet, Craftsman, Troy-Bilt, and Huskee lawn tractors. It replaces OEM part numbers 954-05040, 954-0241A, 754-0241A, and 754-05040.

Fitment & Compatibility

Before buying, verify your mower’s deck size and model number. This belt fits 42-inch and 46-inch decks on models like the Craftsman T110, Troy-Bilt Pony, Cub Cadet LT1050, and Huskee LT4200. Cross-check your OEM number—common matches include 954-0241, 754-0241, and CMXGZAM501087. Measure your old belt’s length and width: it must be exactly 5/8" wide and 35.25" long (outside circumference). Aftermarket belts may vary slightly in length, so stick with aramid or OEM for consistent tension. Check your deck’s spindle and pulley condition—worn pulleys will shorten belt life.

Key Things to Know

• Material: Aramid cord resists stretching and heat better than standard rubber, but it’s stiffer—expect a tight initial fit.
• Installation: Moderate difficulty. You’ll need to remove the deck, release the tensioner, and route the belt around three spindles and an idler pulley. Use a diagram or take a photo before removal.
• Common Gotchas: The belt may appear too short if the tensioner isn’t fully released. Also, verify your deck has a single-belt (not dual-belt) drive system—some models use separate belts for each spindle.
• Lifespan: With proper tension and clean pulleys, expect 2–3 seasons of regular mowing. Replace if you see cracking, glazing, or fraying.

Should You Buy It

If you need a direct, drop-in replacement for a 35.25-inch deck drive belt on a compatible MTD/Cub Cadet/Craftsman tractor and want aramid’s durability without paying OEM prices, this is a solid choice. Avoid it if you have a different belt length or a dual-belt deck system.
