954-04249A Lower Drive Belt 5/8" x 71" for Huskee LT4200, Craftsman T100, T110, T1000, LT1500, LT2000, Troy Bilt Pony, MTD Lawn Mower Tractor, Replaces 954-04249A Drive Belt 954-04249

What It Is

This is a lower drive belt (5/8" wide, 71" long) that transfers power from the engine pulley to the transmission on specific lawn tractor models, enabling forward/reverse movement. It’s designed for mid-size residential mowers like the Huskee LT4200, Craftsman T100/T110/T1000, Troy-Bilt Pony, and select MTD-built tractors.

Fitment & Compatibility

Before buying, confirm these three things:

• Measured length: The belt must be exactly 71" (outer circumference) and 5/8" wide. Measure your old belt or the pulley distance if possible—slight variations can cause slipping or binding.
• Deck size: Works with 42" and 46" decks on compatible models, but deck size alone doesn’t guarantee fit. Match to your specific model number (e.g., Craftsman 917.xxxxx).
• OEM vs. aftermarket: This is an aftermarket replacement for OEM part 954-04249A. It should fit any tractor originally using that OEM number, but aftermarket belts can vary slightly in material stiffness or edge finish. Check that your tractor uses a single lower drive belt (not a separate deck belt).

Common compatible models: Huskee LT4200, Craftsman T100 (917.270720), T110 (917.273640), T1000, LT1500, LT2000, Troy-Bilt Pony (13AN77BS099). Not for zero-turn or riding mowers with hydrostatic transmissions requiring different belt specs.

Key Things to Know

• Installation difficulty: Moderate. You’ll need to remove the mower deck, release belt tension from the idler pulley, and route around several pulleys. Plan 30–60 minutes if you’re handy; consider a diagram if you’re new.
• Quality: 3.9/5 rating suggests decent durability for residential use, but some users report shorter lifespan (1–2 seasons) vs. OEM belts if used on rough terrain or with heavy loads.
• Common gotchas: The belt must be routed correctly—wrong path causes slipping or premature wear. Check for worn pulleys or a stretched idler spring before installing; bad bearings can shred a new belt quickly.
• Size verification: A 71" belt is tight on some models. If your old belt measured closer to 70.5", this may be slightly loose. Measure twice.

Should You Buy It

This is a solid budget choice if you own a compatible Craftsman, Huskee, or Troy-Bilt tractor and need a quick replacement for basic mowing. It’s not for heavy commercial use or if you want OEM-level durability—consider spending more for a Kevlar-reinforced belt if you mow more than 1–2 acres weekly. For the price, it’s a fine stopgap or occasional-use part.
