What It Is

This is a 42-inch deck drive belt (1/2" wide, 96.5" effective length) designed to transfer power from the engine pulley to the mower deck blades on select Craftsman, MTD, and Cub Cadet lawn tractors. Commonly used for mid-size residential mowers with a 42-inch cutting deck.

Fitment & Compatibility

Before buying, measure your old belt’s length (end-to-end, not loop) and width—this belt is 96.5" long and 1/2" wide. It replaces OEM part numbers 954-04060, 954-04060A, 954-04060B, 954-04060C, 754-04060, 754-04060A, 754-04060B, 754-05056, and 954-05056. Fits Craftsman, MTD, Cub Cadet, and Troy-Bilt tractors with a 42-inch stamped steel deck (model numbers typically start with 917 or 13A). Verify your deck model and pulley configuration—some 42" decks use a 95" or 98" belt. Not compatible with zero-turn mowers or older 38" decks.

Key Things to Buy

• Quality: This is an aftermarket belt—comparable to OEM but may be slightly stiffer. Check for reinforced Kevlar or cogged construction if you mow heavy grass.
• Installation: Moderate difficulty (30-45 minutes). You’ll need a socket set and possibly a belt tensioner tool. Route the belt exactly as the old one—take a photo before removal.
• Common gotchas: The 96.5" length is critical; 1/2" too short or long will cause slipping or deck damage. Also check that your deck spindles spin freely—sticky spindles can snap a new belt quickly.
• Warranty: Most aftermarket belts carry a 90-day warranty—test fit before final tensioning.

Should You Buy It

If you need a budget-friendly replacement for a worn or snapped 42-inch deck belt on a standard Craftsman, MTD, or Cub Cadet tractor, this is a solid pick. It’s not premium, but at $15.59 with solid reviews, it’s reliable for typical residential mowing. Avoid if you require a heavy-duty or OEM-specific belt for commercial use.
