What It Is

This is a 1/2" x 108" aramid cord deck belt that drives the mower blades on select Cub Cadet, MTD, Troy-Bilt, and Craftsman lawn tractors (typically 42–50-inch decks). It replaces OEM part numbers 754-05087, 954-05087, 754-05087A, 954-05087A, and CMXGZAM501083.

Fitment & Compatibility

Check these before buying:

• Original part numbers: Confirm your old belt ends in 05087 or CMXGZAM501083.
• Length: It must be exactly 108 inches (measured flat, not stretched). Measure your old belt if possible—many 42–50-inch decks use this length.
• Width: 1/2 inch. Do not use a 5/8-inch belt on a 1/2-inch pulley.
• Brand/model: Fits many Cub Cadet LT/LTX, Troy-Bilt Super Bronco/Pony, MTD Yard Machines, and Craftsman LT1000/LT2000 series. Always cross-reference your mower’s model number (e.g., 13A-xxx) on the OEM parts list.
• Aftermarket vs OEM: Aramid cord is stronger than standard rubber, but it is not an OEM belt. It works fine for replacement if dimensions match.

Key Things to Know

• Quality: Aramid cord resists heat and stretching better than standard Kevlar belts. Expect longer life on rough terrain or heavy grass.
• Installation: Moderate difficulty—you’ll need to release the deck tensioner pulley to slide the belt on. A serpentine belt tool helps. Allow 20–40 minutes.
• Common gotcha: If your belt is 108.5 inches or longer, this will be too tight. Always measure the old belt flat (not looped) before ordering.
• Break-in: New belts may squeak for the first 1–2 hours. If squeaking persists, check pulley alignment.

Should You Buy It

Buy this if you need a direct replacement for a 754-05087 or CMXGZAM501083 belt on a 42–50-inch deck and want better durability than standard rubber. It’s a solid value at $19.99, but confirm your belt length exactly—any mismatch will cause poor cutting or belt damage.
