1/2" X 108" Mower Deck Belt for Cub Cadet/MTD/Troy-Bilt/Craftsman 754-05087, 954-05087, XT1-LT46 XT2-LX46 46 Inch Deck

What It Is

This is a 1/2-inch wide, 108-inch long V-belt that drives the mower blades on select 46-inch deck lawn tractors from Cub Cadet, MTD, Troy-Bilt, and Craftsman. It’s a direct replacement for OEM part numbers 754-05087 and 954-05087, used on models like the XT1-LT46 and XT2-LX46.

Fitment & Compatibility

Before buying, confirm these three things:

• Deck size: Only for 46-inch decks. Measure your deck if unsure—this belt is 108 inches in circumference.
• Model number: Check your mower’s model tag (under seat or on frame). It must list one of these: Cub Cadet XT1-LT46, XT2-LX46, or any MTD/Troy-Bilt/Craftsman 46-inch deck using OEM 754-05087 or 954-05087.
• Belt dimensions: Measure your old belt’s width (1/2 inch) and length (108 inches end-to-end). This belt is aftermarket, not OEM, but matches these specs. Avoid if your original belt is 5/8-inch wide or longer/shorter than 108 inches.

Key Things to Know

• Quality: At $15, it’s a budget aftermarket belt. Expect decent performance for residential use, but it may wear faster than OEM belts under heavy or commercial mowing.
• Installation difficulty: Moderate. You’ll need to release deck tension (usually a spring-loaded idler pulley) and route the belt around the spindles and pulleys. Watch a video for your specific model—routing errors cause poor blade engagement.
• Common gotcha: This belt fits many MTD-built 46-inch decks, but not all. Double-check your deck’s part number (e.g., 46A or 46C) against the OEM 754-05087 list. Some newer Cub Cadet models (like XT3) use a different belt length.
• No warranty: Aftermarket belts rarely carry a warranty. Verify fitment before cutting tags.

Should You Buy It

Buy this if you have a 46-inch Cub Cadet, MTD, Troy-Bilt, or Craftsman lawn tractor that uses OEM 754-05087 or 954-05087, and you want an affordable replacement for light residential mowing. Skip it if you need an OEM belt for commercial use or if your deck is not exactly 46 inches—measure twice to avoid returns.
