954-05040 Upper Drive Belt 5/8" x 35-1/4" - Replacement for MTD Craftsman Troy-Bilt Cub Cadet Yard Machines Huskee Lawn Tractor/Riding Mower, Replaces 754-05040 954-0241 954-0241A 754-0241 754-0241A

What It Is

This is the upper drive belt for MTD-manufactured lawn tractors and riding mowers, connecting the engine pulley to the transmission or deck drive system. It’s designed for 5/8-inch wide pulleys and measures 35-1/4 inches in outer circumference, making it a common replacement for older Craftsman, Troy-Bilt, Cub Cadet, and Yard Machines models.

Fitment & Compatibility

Before buying, confirm three things:

• Measure your old belt – It must be exactly 5/8” wide and 35-1/4” long (outer circumference). Slight variations (e.g., 35” or 35.5”) may not fit or tension correctly.
• Check your model number – This belt replaces OEM numbers 754-05040, 954-0241, 954-0241A, 754-0241, and 754-0241A. It fits many MTD/Cub Cadet tractors with 42-inch or 46-inch decks, but not all. Look up your machine’s model number on the frame or under the seat.
• Deck size matters – This is the upper drive belt, not the deck belt. Verify you’re replacing the belt that runs from the engine to the transmission or pulley system, not the blade belt.

Key Things to Know

• Quality – This is an aftermarket belt (not OEM Cub Cadet), but at $6.99 it’s a budget-friendly option. Expect standard rubber construction; it may not last as long as a genuine OEM belt under heavy use.
• Installation difficulty – Moderate. You’ll need to relieve tension by loosening the idler pulley or removing a belt guard. A belt tool or wrench helps. Plan for 20–40 minutes.
• Common gotcha – The belt can slip if the idler pulley is worn or misaligned. Inspect pulleys for grooves, rust, or wobble before installing. Also check that your deck is disengaged and the engine is off.
• Double-check length – If your old belt measures 35” or 35.5”, this 35.25” belt may still work, but it could be tight or loose. Measure twice.

Should You Buy It

If you need a quick, cheap replacement for an MTD/Craftsman/Troy-Bilt riding mower upper drive belt and you’re comfortable with a basic DIY install, this belt is a solid value. It’s not ideal for heavy commercial use or if you prefer OEM longevity, but for occasional home mowing, it’ll get the job done without breaking the bank.
