954-05025 754-05025 54in Deck Drive Belt for Cub Cadet Craftsman Troy-Bilt 954-05025A, 754-05025A, CMXGZAM501064, 490-501-C064 Lawn Mower(5/8" x 139")

What It Is

This is a 54-inch deck drive belt (5/8" x 139") for select Cub Cadet, Craftsman, and Troy-Bilt zero-turn mowers. It transfers power from the engine pulley to the deck spindles, driving the blades on mowers with a 54-inch cutting deck.

Fitment & Compatibility

Before buying, verify the following:

• Deck size: Must be a 54-inch deck. This belt does not fit 42", 46", or 50" decks.
• Belt dimensions: Exactly 5/8" wide x 139" long. Measure your old belt or check your deck manual to confirm.
• OEM part numbers: Replaces OEM numbers 954-05025, 754-05025, 954-05025A, 754-05025A, CMXGZAM501064, and 490-501-C064.
• Brand/model fit: Fits many Cub Cadet ZT1 54, Craftsman ZT 7000 54, and Troy-Bilt Mustang 54 models. Check your mower’s model number against a compatibility list.
• Aftermarket note: This is an aftermarket belt—not genuine Cub Cadet—but matches OEM specs. It may have a slightly different feel or stiffness than the original.

Key Things to Know

• Quality: Made from standard rubber/cord construction. Good for occasional use, but may wear faster than OEM on heavy-duty or commercial mowing.
• Installation difficulty: Moderate. You’ll need to remove the deck, release the belt tension (usually a spring-loaded idler pulley), and route the belt around all pulleys. A belt diagram is helpful.
• Common gotcha: The belt must be routed exactly as the original. A wrong path causes slipping, poor blade engagement, or belt damage. Take a photo before removing the old belt.
• No installation hardware included: You may need to reuse your original pulleys and tensioner. Check for worn bearings or seized idlers before installing.

Should You Buy It

This belt is a solid budget option for homeowners with a 54-inch zero-turn mower who need a quick replacement. It’s not for heavy commercial use or if you want OEM longevity. If you mow frequently or have a high-horsepower machine, consider the genuine Cub Cadet belt instead.
