What It Is

This is a 42-inch deck drive belt (1/2" x 67") for MTD-branded lawn tractors and zero-turn mowers, including Troy-Bilt, Cub Cadet, and Bronco models. It transfers power from the engine pulley to the mower deck blades.

Fitment & Compatibility

• Deck size: 42-inch cutting decks only (not 46", 50", etc.).
• Brands: MTD, Troy-Bilt (Bronco, Super Bronco), Cub Cadet (LT1018, RZT-L42, RZT-S54), and other MTD-built machines.
• OEM cross-references: 954-0498, 754-04317, 954-04317A. Aftermarket replacements may use different part numbers—always confirm your mower’s OEM part number.
• Measurements: 1/2" wide, 67" effective length. Measure your old belt’s width and length (outer circumference) to verify. A 1/2" width is standard for many residential decks.
• Check: Your mower’s model number (on a sticker under the seat or on the frame) and the old belt’s part number. This belt will not fit 38" or 54" decks, nor non-MTD brands like John Deere or Husqvarna.

Key Things to Know

• Aramid cord construction: Stronger than standard rubber belts, resists stretching and heat better. Good for heavy grass or frequent use.
• Installation difficulty: Moderate—requires removing the deck or accessing the belt routing under the mower. Refer to your manual for the correct belt path. A diagram is often printed on the deck itself.
• Common gotchas: (1) Deck pulley alignment—worn pulleys can cause premature belt wear. (2) Belt tension—too loose causes slipping, too tight strains bearings. (3) Not all 42" decks use the same belt—some require a shorter 66" or longer 68" belt, so measure before buying.
• Customer feedback: Mixed reviews (3.9 stars)—some report good fit and durability, others note early fraying or slight length variation. For a perfect OEM fit, consider the genuine Cub Cadet part.

Should You Buy It

Buy this belt if you need a replacement for a 42-inch MTD/Cub Cadet deck and want an aramid-cord option at a lower price than OEM. It’s a solid choice for moderate use, but if you demand exact fitment or have a high-hour mower, stick with the genuine Cub Cadet belt to avoid routing or tension issues.
