954-04060C Lawn Mower Deck Belt 1/2" x 96-1/2" - Replacement for Troy-Bilt 954-04060B 754-04060B 754-04060C - Fits 42" Troy-Bilt LT1040 LT1042 Craftsman Cub Cadet John Deere Riding Mowers

What It Is

This is a 1/2-inch wide by 96-1/2-inch long V-belt that drives the mower deck blades on select 42-inch riding mowers. It’s a direct replacement for worn or broken OEM belts on Troy-Bilt, Craftsman, Cub Cadet, and John Deere models.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch cutting deck. The belt measures exactly 1/2” wide and 96-1/2” long (outside circumference). It replaces OEM part numbers 954-04060C, 954-04060B, 754-04060B, and 754-04060C. Fits common models including Troy-Bilt LT1040, LT1042, Craftsman 917 series, Cub Cadet LT1042, and John Deere 100-series with 42” decks. Double-check your owner’s manual or existing belt part number—this belt will NOT fit 46” or 54” decks or zero-turn mowers.

Key Things to Know

• Quality: Aftermarket belt, but reviews indicate it matches OEM specs. Check for fraying or cracking before installation—some users report slight variance in rubber hardness.
• Installation: Moderate difficulty. You’ll need to remove the deck or release belt tension via the idler pulley. A belt routing diagram is helpful—take a photo of the old belt before removal.
• Common gotcha: Measure the old belt length (end-to-end, flat) to verify 96.5”. Some aftermarket belts are slightly shorter or longer and may cause slipping or poor blade engagement.
• Lifespan: Expect 1-2 seasons of normal residential use. Debris buildup on pulleys accelerates wear.

Should You Buy It

If your mower is a 42-inch Troy-Bilt, Craftsman, Cub Cadet, or John Deere riding mower and you need a budget-friendly replacement that matches OEM specs, this belt is a solid pick. It’s not for commercial use or odd-sized decks, but for standard residential mowing, it’s a reliable, affordable fix.
