Lawn Mower Upper Drive Belt Replace 954-05040 954-0241 for Craftsman Troy Bilt Cub Cadet Yard Machines Replacement Part Accessories, 5/8 Inch x 35.25 Inch

What It Is

This is a replacement upper drive belt for riding lawn mowers, specifically designed for select Craftsman, Troy-Bilt, Cub Cadet, and Yard Machines models. It transfers power from the engine pulley to the transmission, controlling forward/reverse movement.

Fitment & Compatibility

• Measurements: 5/8 inch width x 35.25 inch length (outer circumference). Confirm your old belt matches these exact dimensions.
• OEM Cross-References: Replaces OEM part numbers 954-05040 and 954-0241. Check your mower’s manual or current belt for these numbers.
• Brand Fit: Works on many Craftsman (LT1000/1500/2000 series), Troy-Bilt, Cub Cadet (LT1040/1042/1050), and Yard Machines models with 42-inch or 46-inch decks. Not universal—verify your model number online.
• Deck Size: Belt is for the drive system, not the deck. Deck size is irrelevant for this belt; focus on transmission type (hydrostatic or manual).

Key Things to Know

• Quality: Aftermarket belt, not OEM. Expect decent performance for the price, but may wear slightly faster than a genuine Cub Cadet belt.
• Installation Difficulty: Moderate. You’ll need to remove the mower deck and possibly a belt guard. A belt routing diagram is helpful—take a photo before removal.
• Common Gotcha: If your mower has a 42-inch deck and a hydrostatic transmission, this belt often fits. For manual transmissions, double-check the length; some require a 37-inch belt.
• Tension Check: After installation, ensure the belt is taut but not overly tight. Loose belts cause slipping; overtightening can damage pulleys.

Should You Buy It

Yes, if you need a budget-friendly replacement for a worn upper drive belt on a compatible Craftsman, Troy-Bilt, or Cub Cadet riding mower. It’s a solid value for the price, but verify your model and belt dimensions first. Avoid if you want OEM durability or have a non-standard transmission.
