954-04249A Lower Drive Belt Kevlar for Troy Bilt Pony Drive Belt, Huskee LT4200, Craftsman T100, T110, T1000, LT1500, LT2000, MTD Riding Mower, Replace 954-04249 - Aramid Cord, 5/8'' x 71''

What It Is

This is a Kevlar-reinforced lower drive belt (5/8’’ x 71’') that transfers power from the engine pulley to the transmission on select Troy-Bilt Pony, Huskee, Craftsman, and MTD riding mowers. It’s designed for machines with a hydrostatic or manual transmission where the belt drives the wheels, not the blades.

Fitment & Compatibility

Before buying, confirm three things:

• Belt dimensions: Must be exactly 5/8’’ wide and 71’’ long (outside circumference). Measure your old belt or check your mower’s manual.
• Machine models: Directly replaces OEM part 954-04249. Fits Troy-Bilt Pony (2000s–2010s), Huskee LT4200, Craftsman T100/T110/T1000/LT1500/LT2000, and many MTD-built riders with a 42’’ deck (but deck size doesn’t always guarantee fit—check the transmission type).
• Cross-check: If your mower uses a different belt length (e.g., 72’’ or 5/8’’ x 70.5’'), this won’t work. Also verify your model number on the manufacturer’s site—aftermarket belts can vary slightly in tension.

Key Things to Know

• Material: Aramid cord (Kevlar-like) offers better durability and less stretch than standard rubber belts, especially under heavy load or in hot conditions.
• Installation: Moderate difficulty. You’ll likely need to remove the deck or belt guard, release tension from the idler pulley, and route the belt around the engine and transmission pulleys. A belt tool or long screwdriver helps.
• Common gotcha: If your mower has a separate blade drive belt (not this one), don’t confuse them—the lower drive belt is thinner and longer. Also, check pulley condition (worn or bent pulleys can cause premature belt failure).
• Noise/break-in: Some users report a slight squeak during the first few minutes of use; this usually subsides as the belt seats.

Should You Buy It

If you own one of the listed models and need a reliable, long-lasting replacement for the OEM 954-04249 belt, this is a solid value at $18. It’s a step up from basic rubber belts and should handle typical residential mowing without issue. Avoid it if your mower requires a different belt length or if you’re looking for a heavy-duty commercial-grade option—this is best for light-to-moderate homeowner use.
