Drive Belt 3/8 Inch X31 Inch for Troy-Bilt/MTD/Cub Cadet 754-04282, 954-04282, SC500 Walk Behinds

What It Is

This is a replacement drive belt (3/8" wide x 31" long) for select Troy-Bilt, MTD, and Cub Cadet walk-behind mowers. It transfers power from the engine pulley to the wheels, enabling self-propelled movement.

Fitment & Compatibility

Before buying, confirm your mower model uses a 3/8" x 31" belt (OEM numbers 754-04282 or 954-04282). This fits most Troy-Bilt, MTD, and Cub Cadet walk-behinds with 21" or 22" decks, including the SC500 series. Check your old belt’s length (measure end-to-end, not around pulleys) and width. If your mower has a different OEM belt number (e.g., 754-04283 or 954-04283), this won’t fit. Also verify your mower’s model number from the underside of the seat or frame—this belt is not for zero-turn or riding mowers.

Key Things to Know

• Quality: OEM-spec but aftermarket price—durable enough for residential use, but may wear faster under heavy commercial duty.
• Installation: Moderate difficulty. You’ll need to remove the blade, deck pulley, or belt cover. Watch for belt routing diagrams under the deck or in the manual.
• Common gotcha: The 31" length is critical—a 30" or 32" belt will slip or be too tight. Use a tape measure on the old belt, not a ruler.
• Signs of wear: Cracking, fraying, or glazing on the belt edges. Replace if the mower hesitates or jerks in motion.

Should You Buy It

Yes, if you need an affordable, direct replacement for a Troy-Bilt, MTD, or Cub Cadet walk-behind mower using a 3/8" x 31" drive belt. It’s a solid value for residential lawn care, but skip it for heavy commercial use or if your mower requires a different belt length or width.
