954-05040 954-0241A Upper Drive Belt Kevlar for Troy Bilt Pony Drive Belt, Craftsman, MTD, Murray, Huskee Riding Mower, Replace 754-05040, 754-0241A, 954-0421 - Aramid Cord, 5/8'' x 35-1/4''

What It Is

This is an aftermarket upper drive belt (5/8" wide x 35-1/4" long) made with aramid cord (Kevlar-like material) for select Troy-Bilt Pony, Craftsman, MTD, Murray, and Huskee riding mowers. It transfers power from the engine pulley to the transmission or transaxle, enabling forward/reverse drive.

Fitment & Compatibility

Check these before buying:

• Measure your old belt: This belt is 5/8" wide and 35-1/4" long. If your existing belt is a different length or width, it won’t fit.
• Verify OEM part numbers: Directly replaces 954-05040, 954-0241A, 754-05040, 754-0241A, and 954-0421. Cross-reference with your mower’s manual.
• Common compatible models: Troy-Bilt Pony (various years, typically 42" deck), Craftsman LT1000/LT2000 series, MTD Yard Machines, Murray WideBody, and Huskee 42" riding mowers. Not for zero-turn or garden tractors.
• Deck size: Often used on 42" and 46" deck models, but always confirm via your model number (tag under seat or frame).

Key Things to Know

• Aramid cord vs. standard: Aramid is stronger and more heat-resistant than standard rubber belts, but it can be stiffer and may require a short break-in period (expect minor squeaking initially).
• Installation difficulty: Moderate. You’ll need to remove the mower deck or access the belt path under the engine. A belt routing diagram (often on the mower deck or in the manual) is essential.
• Common gotcha: This is the upper drive belt, not the deck belt. Do not confuse it with the belt that spins the blades. Also, check that the belt tensioner pulley and idler pulleys spin freely before installing.
• No OEM fit guarantee: While it matches OEM specs, aftermarket belts can vary slightly in thickness or stiffness. If your mower has a tight belt path, it may feel snug.

Should You Buy It

Buy this if you need an affordable, durable replacement for a worn upper drive belt on a compatible Troy-Bilt, Craftsman, or MTD riding mower and you’re comfortable with a moderate DIY install. Skip it if you want a factory OEM belt or if your mower requires a different length/width—measure first to avoid returns.
