Transmission (Lower) Belt 754-04249/ Kevlar Cord / 5/8" x 71" - Compatible with MTD 754-04249A 954-04249, 954-04249A Pony 42T, Pony 36T, Pony 42X, TB42 7-Speed

What It Is

This is a Kevlar-cord reinforced lower transmission drive belt (5/8" wide x 71" long) for MTD-branded lawn tractors—specifically Pony 42T, Pony 36T, Pony 42X, and TB42 7-speed models. It transfers power from the engine to the transmission, enabling forward/reverse movement.

Fitment & Compatibility

Before buying, confirm three things:

1. Deck size & model: Fits 36" and 42" decks on MTD Pony and TB42 series. Not for zero-turn or riding mowers with hydrostatic transmissions.
2. OEM cross-reference: Replaces MTD 754-04249, 754-04249A, 954-04249, and 954-04249A. If your original part number matches any of these, it’s compatible.
3. Measure your old belt: Must be exactly 5/8" wide and 71" outside circumference. A half-inch off in length will cause slipping or binding.

Tip: Check your mower’s model number (under seat or on frame) against MTD’s compatibility list. This belt will not fit Cub Cadet, Troy-Bilt, or Yard Machines unless they share the same MTD platform.

Key Things to Know

• Kevlar cord vs. standard: Kevlar handles higher torque and resists stretching better than rubber-only belts. Good for heavy grass or uneven terrain.
• Installation difficulty: Moderate. You’ll need to remove the mower deck and possibly the belt guard. Expect 30–60 minutes if you’re handy with a wrench.
• Common gotcha: The belt routing diagram is often printed on the mower deck or in the manual—snap a photo before removing the old belt. Wrong routing = no drive.
• Price vs. OEM: At $21.99, it’s roughly half the cost of an MTD-branded belt. Reviews indicate it lasts 1–2 seasons under normal residential use.

Should You Buy It

If you own an MTD Pony or TB42 with a 36" or 42" deck and need a reliable, budget-friendly replacement for the OEM belt, this Kevlar option is a solid choice. It’s not for commercial use or odd-size decks, but for standard residential mowing, it delivers good value and durability at half the OEM price.
