5/8" x 71" Lower Drive Belt 954-04249A,for754-04249, 754-04249A, 954-04249, 954-04249A Drive Belt, Fits MTD, Troy-Bilt Pony Tuffy, Craftsman T100 T110 T1000 LT1500 LT2000 Lawn Mowers

What It Is

This is a 5/8" wide, 71" long lower drive belt (OEM cross 954-04249A) that transfers power from the engine pulley to the mower deck spindle and transmission drive. It’s designed for residential riding mowers from MTD, Troy-Bilt (Pony/Tuffy), and Craftsman (T100/T110/T1000/LT1500/LT2000 series) with 42" to 46" decks.

Fitment & Compatibility

• Confirm deck size: Works with 42", 46", and some 50" decks—check your mower’s manual or deck stamp for exact size.
• Model series: Fits MTD, Troy-Bilt Pony/Tuffy, Craftsman T100/T110/T1000/LT1500/LT2000. Not universal for all Craftsman or Troy-Bilt models (e.g., LT1000 uses a different belt).
• OEM vs aftermarket: This is an aftermarket replacement for OEM part numbers 754-04249, 754-04249A, 954-04249, 954-04249A. Verify your old belt’s part number or measure length (71") and width (5/8") before buying.
• Belt routing: Some decks require a specific routing path—take a photo of the old belt before removal, or consult the mower’s belt diagram (often under the seat or deck).

Key Things to Do

• Check for wear on pulleys: Worn or rough pulleys will shred a new belt fast. Inspect and replace if needed.
• Installation difficulty: Moderate. You’ll need to remove the deck or use a spring puller to release tension. Expect 30–60 minutes.
• Common gotchas: The belt may be tight on first install—use a socket wrench on the tensioner pulley to relieve tension. Don’t oil or lubricate the belt.
• Quality: This is a budget-friendly aftermarket belt. It works, but may have slightly shorter lifespan than OEM (1–2 seasons vs 2–3). Fine for light residential use.

Should You Buy It

If you have a Troy-Bilt Pony/Tuffy or Craftsman T100/T110/T1000/LT1500/LT2000 with a 42–46" deck and need a quick, affordable belt for regular mowing, this fits the bill. It’s not a heavy-duty belt for commercial use or rough terrain, but for weekend lawn care at $12.99, it’s a solid value.
