954-04249A Lawn Mower Drive Belt 5/8"x71" Fits for 754-04249 954-04249, for Craftsman LT1500 LT2000 T110 Huskee LT4200 Troy Bilt Pony 42" Decks

What It Is

This is a 5/8-inch wide, 71-inch long drive belt that transfers power from the engine pulley to the mower deck spindles on select 42-inch cutting deck lawn tractors. It’s a direct replacement for OEM part numbers 754-04249 and 954-04249, commonly used on Craftsman, Huskee, and Troy-Bilt models with 42-inch fabricated or stamped decks.

Fitment & Compatibility

Before buying, confirm three things:

1. Deck size – This belt only fits 42-inch decks. Measure your deck cutting width or check the model tag under the seat or on the frame.
2. Model list – Fits Craftsman LT1500, LT2000, T110, Huskee LT4200, and Troy-Bilt Pony with 42-inch decks. Not all variants of these models use the same belt—verify your OEM part number matches 754-04249 or 954-04249.
3. Belt dimensions – Measure your old belt’s width (5/8”) and length (71”). If your old belt is longer or shorter, this won’t work. Also check pulley groove width—some older decks use a 1/2” belt.

Pro tip: Check your owner’s manual or the existing belt’s part number stamped on the side. Cross-reference on the manufacturer’s site if unsure.

Key Things to Know

• Quality – This is an aftermarket belt, not OEM. Users report it’s slightly thinner rubber than the original, but it holds up well for typical residential mowing. Expect 1-2 seasons of normal use.
• Installation difficulty – Moderate. You’ll need to remove the deck, release the belt tensioner, and route the belt around all pulleys per your deck diagram. A belt tool or long screwdriver helps.
• Common gotcha – The belt may feel tight on first install. Run the deck at full throttle for 5 minutes to break it in and seat it properly. Check tension after the first hour.
• Deck alignment – If your old belt wore unevenly or slipped, check for bent spindles or a worn tensioner pulley before installing the new belt. Replacing the belt alone won’t fix alignment issues.

Should You Buy It

If you need a reliable, affordable replacement for a 42-inch deck on a Craftsman, Huskee, or Troy-Bilt tractor and your old belt is worn or broken, this is a solid choice. It’s not built for commercial-grade abuse, but for weekly residential mowing, it delivers good value. Skip it if you need an exact OEM match or have a different deck size.
