What It Is

This is a 48-inch lawn mower deck belt (5/8" wide x 111.25" long) designed for John Deere and Cub Cadet garden tractors. It transfers power from the engine pulley to the mower blades, and the aramid cord construction offers higher strength and heat resistance than standard rubber belts.

Fitment & Compatibility

Before buying, verify three things: deck size (must be 48-inch), belt length (111.25 inches), and belt width (5/8 inch). This belt fits John Deere models GT235, X300, X320, X500, 320, 345, 325, 335, 180, 245, 265, LX280, GX345, and GT275. It also replaces Cub Cadet OEM numbers 954-04055, 754-04055, and 754-04041. Check your mower’s deck part number – some 48-inch decks use a different belt length (e.g., 110.5 inches). Measure your old belt end-to-end (not stretched) to confirm. This is an aftermarket belt, not OEM John Deere or Cub Cadet.

Key Things to Know

• Quality vs OEM: Aramid cord is stronger than standard rubber, but some users report slightly shorter lifespan than OEM belts under heavy use.
• Installation difficulty: Moderate – requires removing the mower deck and routing the belt around pulleys. A deck lift or jack helps.
• Common gotcha: The belt may appear tight initially but will stretch slightly after first use. Re-check tension after 2–3 hours.
• Deck pulley condition: Worn or sticky pulleys can cause premature belt wear. Inspect and clean pulleys before installing.

Should You Buy It

If you need a reliable, budget-friendly replacement for a 48-inch deck belt on a compatible John Deere or Cub Cadet tractor, this is a solid choice. It’s not the longest-lasting option for commercial use, but for home lawn care and occasional mowing, the aramid cord provides good value at this price point.
