What It Is

This is a 5/8-inch wide by 139-inch long V-belt designed for 54-inch cutting decks on select MTD, Cub Cadet, and Troy-Bilt lawn tractors. It drives the deck blades from the engine pulley and is a direct replacement for OEM part numbers 754-05025, 954-05025, 954-05025A, CMXGZAM501064, 490-501-C064, and 490-501-M064.

Fitment & Compatibility

Before buying, verify your deck size is exactly 54 inches (measured blade tip to blade tip). This belt fits many Cub Cadet LTX, XT1, XT2, and GT series; Troy-Bilt Mustang, Pony, and Bronco; as well as MTD Yard Machines and Huskee models with a 54-inch fabricated or stamped deck. Check your owner’s manual for the specific OEM part number—this belt matches the list above. Physically measure your old belt’s length (end to end, not around pulleys) if possible; a 139-inch belt is standard for these decks. This is an aftermarket belt, not genuine OEM, but uses the same dimensions and material grade.

Key Things to Know

• Quality: Aftermarket belt is typically made from rubber or Kevlar-reinforced material; OEM belts may last slightly longer but cost 2-3x more. This one has a 4.8-star rating from 27 reviews, indicating good durability for residential use.
• Installation: Moderately easy—requires removing the deck or using a tensioner release. Follow your mower’s belt routing diagram (usually under the deck or in the manual) to avoid misrouting. A belt tool or pry bar helps with tensioner.
• Common gotchas: Double-check your deck’s belt length—some 54-inch decks use 140-inch or 141-inch belts. Also ensure your pulley sizes match (stock pulleys are typically 5/8-inch width). This belt will not fit zero-turn mowers or decks smaller than 54 inches.
• Warranty: Aftermarket belts usually carry a 90-day to 1-year warranty; check the seller’s policy before buying.

Should You Buy It

If you own a 54-inch deck MTD/Cub Cadet/Troy-Bilt lawn tractor and need a reliable, budget-friendly replacement for residential mowing, this belt is a solid choice. It’s well-reviewed, fits the listed OEM numbers, and saves you money over genuine parts—just confirm your deck length and model compatibility first.
