UDC Parts 954-05040 Upper Drive Belt Replacement - 35.25 Inches Length - for Craftsman T110 954-0241A Upper Drive Belt 754-0241A 9540241A 95405040 Troy Bilt Pony MTD/Aramid Cord

What It Is

This is a 35.25-inch upper drive belt for lawn tractors, connecting the engine pulley to the transmission. It’s specifically designed for Craftsman T110 and similar MTD-built models (like Troy-Bilt Pony) that use this belt to engage forward/reverse motion.

Fitment & Compatibility

Before buying, verify:

• Exact length: 35.25 inches (measure your old belt or consult your manual; even 0.5” off can cause slipping or damage).
• Model numbers: Replaces OEM 954-0241A, 754-0241A, 9540241A, and 95405040. Fits Craftsman T110, Troy-Bilt Pony, and other MTD-chassis tractors with 42-inch decks (check your deck size—larger decks often use a different belt).
• Upper vs. lower: This is the upper drive belt (transmission). The lower belt is for the mower deck—don’t mix them up.
• Aftermarket note: UDC is a reputable aftermarket brand. It’s not OEM, but it matches OEM specs and has strong reviews.

Key Things to Know

• Aramid cord construction – More durable than standard rubber belts; resists stretching and heat better.
• Installation difficulty: Easy to moderate. You’ll need a wrench to release the idler pulley tension. No special tools required.
• Common gotcha: If your tractor won’t move or moves sluggishly, check that the belt is routed correctly around the idler and not twisted. A misrouted belt will slip immediately.
• Check pulley condition: Worn or rusty pulleys can shred this belt quickly. Inspect and clean before installing.

Should You Buy It

Yes, if you need a reliable, budget-friendly replacement for a Craftsman T110 or similar MTD tractor’s upper drive belt. It’s a direct fit, well-reviewed, and cheaper than OEM. Skip it only if you need a deck belt (lower belt) or have a different brand/model with a different belt length.
