What It Is

This is a 118 1/4-inch long, 1/2-inch wide deck drive belt that transfers power from the engine pulley to the mower deck blades. It’s designed for riding lawn mowers and zero-turn mowers from Cub Cadet, MTD, Husqvarna, AYP, Simplicity, and Snapper—typically for 42-inch to 54-inch decks.

Fitment & Compatibility

Before buying, confirm your mower’s model number and deck size. This belt replaces OEM part numbers: Cub Cadet/MTD 754-04033, 754-04033A, 954-04033, 954-04033A; Husqvarna/AYP 574173003; Simplicity/Snapper 1732956, 1732956SM, GX25628. Measure your old belt’s length (118.25 inches) and width (0.5 inches) to verify. It fits most MTD-built decks with a single belt drive system—check your deck’s belt routing diagram (usually on the deck or in the manual). Avoid using on decks requiring a different length or width (e.g., 1/2-inch vs 5/8-inch belts are not interchangeable).

Key Things to Know

• Aramid cord construction: Stronger than standard rubber belts, resists stretching and heat better—good for heavy use or rough terrain.
• Install difficulty: Moderate. You’ll need to remove the deck or access the belt path under the mower. Release tension by disconnecting the deck engagement cable or spring.
• Common gotcha: This belt is not for the blade drive (spindle) belt—it’s the main deck drive belt. Check your routing diagram; some models require looping around a tensioner pulley.
• Wear check: If your old belt is glazed, cracked, or frayed, replace it immediately to avoid slipping or snapping during use.

Should You Buy It

Buy this if you need a direct replacement for the listed OEM part numbers on a Cub Cadet, MTD, Husqvarna, or Simplicity mower with a 118.25-inch deck drive belt. It’s a solid upgrade from a standard rubber belt thanks to the aramid cord, and the price is competitive for the durability. Avoid if your belt measures differently or you need a spindle belt.
