What It Is

This is an aftermarket drive belt designed to transfer power from the engine to the transmission on specific MTD, Troy-Bilt, and White Outdoor lawn tractors. It’s intended for use on walk-behind tractors and garden tractors with 38-inch to 42-inch decks.

Fitment & Compatibility

Before buying, confirm your machine’s model number and deck size. This belt replaces OEM part numbers 754-04249 and 954-04249A. It fits MTD, Troy-Bilt, and White Outdoor tractors including the LT542H, LF058, M115, M135, M155, M175, CLT38G, CLT42G, T110, T105, LT3812, and LT538G. Always measure your old belt’s length and width (typically 1/2-inch wide, 92-96 inches long) to verify. Aftermarket belts may vary slightly in material or tension; check your owner’s manual for exact specs.

Key Things to Know

• Quality: At $13.29, this is a budget-friendly replacement. It may not last as long as an OEM belt, especially under heavy use or in wet conditions. Expect 1-2 seasons of regular mowing.
• Installation: Moderate difficulty. You’ll need to remove the deck, route the belt around pulleys and tensioner, and reinstall. A belt diagram is essential—check your manual or online guides.
• Common gotchas: Belt may be slightly tighter or looser than OEM. If it slips or squeals, recheck routing and tensioner adjustment. Do not overtighten; it can damage pulleys or bearings.
• Compatibility warning: Not all “compatible” listings are accurate. Double-check your deck size (38" or 42") and model number against the list above. Some tractors with identical model numbers may use different belt lengths.

Should You Buy It

This belt is a solid, low-cost option for light-to-moderate mowing on older or secondary tractors where OEM price isn’t justified. If you mow commercially, on steep terrain, or want maximum durability, spend more on an OEM belt. For weekend homeowners with a compatible MTD/Troy-Bilt, it’s a practical buy.
