954-05040 Upper Drive Belt for Troy-Bilt Pony Riding Mowers, Kevlar Cord Reinforced, Replaces 954-0241A, 754-0241A, 954-04057, for MTD Craftsman, 5/8"x35.25"

What It Is

The 954-05040 is a Kevlar-reinforced upper drive belt that transfers power from the engine to the mower deck on Troy-Bilt Pony riding mowers and select MTD/Craftsman tractors. It’s the belt that engages the blades, not the drive belt for the wheels.

Fitment & Compatibility

• Measure first: Belt is 5/8" wide x 35.25" long (outside circumference). If your old belt is different, it won’t fit.
• Direct OEM replacements: 954-0241A, 754-0241A, 954-04057. If your mower uses any of these part numbers, this belt matches.
• Brands/models: Fits most Troy-Bilt Pony models (42" and 46" decks typically), plus many MTD, Craftsman, Cub Cadet, and Yard Machines tractors with similar belt routing. Check your owner’s manual or deck diagram for belt length confirmation.
• Deck size not a guarantee: Same deck size can use different belts. Always verify by part number or belt length, not just deck cut width.

Key Things to Know

• Kevlar cord construction improves durability over standard rubber belts—less stretch and longer life, especially under heavy grass or frequent use.
• Installation is moderate: You’ll need to remove the deck or at least release tension via the idler pulley. Expect 30–60 minutes if you’ve done it before; longer if it’s your first time.
• Common gotcha: Routing matters. Take a photo or draw the belt path before removing the old belt. One wrong wrap around a pulley and blades won’t engage.
• No pulleys included: This is just the belt. Check idler pulleys and spindles for wear while you’re in there—bad pulleys kill belts fast.

Should You Buy It

If you have a Troy-Bilt Pony or compatible MTD/Craftsman tractor needing an upper deck belt, this is a solid, cost-effective choice. The Kevlar reinforcement adds real longevity over basic belts, and the price is fair. Skip it if you need a drive belt (for wheel movement) or if your belt measures differently than 5/8"x35.25".
