46-inch Deck Belt 754-05087 / Kevlar Cord / 1/2" x 108" - Compatible with 954-05087 754-05087A 954-05087A CMXGZAM501083 Cub Ct MTD Troy-Bilt Craftsman

What It Is

This 46-inch deck belt (part 754-05087) drives the mower blades on select Cub Cadet, MTD, Troy-Bilt, and Craftsman lawn tractors with a 46-inch cutting deck. It’s a Kevlar-cord reinforced belt designed for higher durability and reduced stretching under load.

Fitment & Compatibility

Before buying, confirm your mower’s deck size is exactly 46 inches and that your current belt measures 1/2 inch wide by 108 inches long. This belt replaces OEM numbers 754-05087, 954-05087, 754-05087A, 954-05087A, and CMXGZAM501083. It fits many Cub Cadet, MTD, Troy-Bilt, and Craftsman models from the early 2000s onward—check your owner’s manual or look up your model number on the manufacturer’s site. It’s an aftermarket replacement, not OEM, so verify the routing diagram matches your deck (some decks have different idler pulley positions).

Key Things to Buy

• Quality: Kevlar cord resists stretching and heat better than standard rubber belts, but some users report shorter lifespan than OEM on heavy-duty use.
• Installation: Moderate difficulty—requires removing the deck or accessing belt routing under the mower. A belt routing diagram is helpful; take a photo before removing the old belt.
• Common gotchas: The belt may be slightly tighter than OEM, so ensure your idler pulley spring is in good condition. If your deck uses a different belt length (e.g., 105 inches), this won’t fit. Double-check the 108-inch length.

Should You Buy It

If you need a budget-friendly replacement for a standard 46-inch deck belt and don’t mind slightly tighter installation, this Kevlar option offers decent durability for occasional mowing. For commercial or heavy-use mowers, consider OEM for guaranteed fit and longer life.
