What It Is

This is a 134-inch aramid cord deck belt designed to drive the mower blades on select Cub Cadet, MTD, Troy-Bilt, Craftsman, and Toro lawn tractors. It replaces OEM part numbers 954-04077, 754-04077, 754-04077A, and 112-0332. It’s for machines with 50-inch or 54-inch cutting decks, typically used on residential zero-turn and lawn tractors.

Fitment & Compatibility

Before buying, confirm your mower’s model and deck size. This belt fits:

• Cub Cadet: LT1050, XT1 LT50, LT50, LT1050, SLT1550 (all with 50-inch deck)
• MTD: Super Bronco XP50 (50-inch deck)
• Troy-Bilt: Super Bronco XP50
• Craftsman: models with 50-inch deck (check your specific model)
• Toro: GT2100, GT2200 (50-inch deck)

Critical checks:

1. Deck size: Must be 50 inches (some 54-inch decks use a different belt length).
2. OEM vs aftermarket: This is a Cub Cadet-branded part, not a generic aftermarket belt. It should match OEM specs exactly.
3. Measurement: Belt length is 134 inches (134.0” outside circumference). Measure your old belt or compare to the part number on your current belt.
4. Deck configuration: Some models use a separate drive belt for the deck engagement (this is the blade drive belt, not the drive belt).

Don’t assume fit—check your mower’s model number and deck size on the manufacturer’s site or your owner’s manual.

Key Things to Know

• Aramid cord construction: Stronger and more heat-resistant than standard rubber belts—good for high-torque mowing in thick grass.
• Installation difficulty: Moderate. You’ll need to remove the deck, route the belt around pulleys, and re-tension. A diagram from your manual helps. No special tools required beyond a socket set.
• Common gotcha: Verify belt routing before reassembly. Incorrect routing causes slipping, poor cutting, or belt damage. Take a photo before removing the old belt.
• Durability: Aramid cord resists stretching and fraying longer than standard belts, but deck debris (sticks, stones) can still cause premature wear. Inspect pulleys for damage before installing.

Should You Buy It

If you need a direct OEM replacement for a 50-inch deck on a Cub Cadet, MTD, Troy-Bilt, Craftsman, or Toro tractor listed above, this belt is a solid choice. It’s priced competitively with aftermarket options but offers verified fitment and aramid cord durability. Skip it if your deck is 54 inches or if you want a cheaper generic belt—stick with OEM for reliability.
