What It Is

This is a Kevlar-reinforced upper drive belt for riding lawn mowers and zero-turn mowers, designed to transfer power from the engine pulley to the mower deck or transmission drive system. It replaces multiple OEM Troy-Bilt and MTD part numbers and is commonly used on Troy-Bilt models with a 42-inch or 46-inch cutting deck.

Fitment & Compatibility

Before buying, verify your mower’s model number and deck size (typically stamped on the frame or under the seat). This belt crosses to OEM numbers 754-0241, 754-05040, 954-04057, 954-05040, and 954-0241A. It fits many Troy-Bilt, MTD, and Craftsman riding mowers, including those using OEM part 1108544 or 1712912. Measure your old belt’s length (should be about 94.5 inches) and width (roughly 1/2 inch) to confirm. This is an aftermarket replacement, not OEM—check that your mower uses a single upper drive belt (not a dual-belt system).

Key Things to Know

• Kevlar construction offers better heat and wear resistance than standard rubber belts, but it can be stiffer and may require a short break-in period.
• Installation difficulty is moderate—you’ll need to loosen the deck, route the belt around pulleys and idlers, and re-tension. A diagram is helpful.
• Common gotcha: This belt is for the upper drive (engine to deck), not the deck spindle belt. Double-check you’re replacing the correct belt.
• Price vs. OEM: At $9.99, it’s significantly cheaper than OEM belts, but some users report slightly shorter lifespan. Good for budget replacements.

Should You Buy It

If you need a reliable, low-cost replacement for a Troy-Bilt or compatible riding mower’s upper drive belt and are comfortable with a DIY install, this belt is a solid value. It’s not ideal for heavy commercial use, but for residential mowing it offers good performance at a fraction of the OEM price.
