5/8" X134" Deck Belt Made with Aramid for 50 Inch Deck Cub-Cadet/MTD/Troy-Bilt 954-04077 754-04077 954-04077A I1050 LGTX1050 SLT1550, Toro 112-0332 GT2100 GT2200 LX500

What It Is

This is a 5/8-inch wide, 134-inch long deck belt made with aramid (Kevlar-like) fiber reinforcement. It drives the blades on 50-inch cutting decks for select Cub Cadet, MTD, Troy-Bilt, and Toro lawn tractors, including models like the I1050, LGTX1050, SLT1550, GT2100, GT2200, and LX500.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size: Must be exactly 50 inches (measured blade tip to tip). This belt will not fit 46-inch or 54-inch decks.
• OEM part numbers: Cross-reference with 954-04077, 754-04077, 954-04077A (Cub Cadet/MTD/Troy-Bilt) or 112-0332 (Toro). This belt is an aftermarket replacement, not OEM, but matches those specs.
• Physical dimensions: Measure your old belt length (should be 134 inches) and width (5/8 inch). If your deck uses a 1/2-inch wide belt, this won’t work.

Also verify your tractor’s model number—many Cub Cadet XT and LTX series, and Toro TimeCutter or Titan commercial decks use different belts.

Key Things to Know

• Aramid construction: Stronger and more heat-resistant than standard rubber belts, reducing stretch and breakage under heavy grass or wet conditions. Expect longer life than a cheap rubber belt.
• Installation difficulty: Moderate. You’ll need to remove the deck (or at least the belt guard and mule drive), route the belt around spindles and tensioner pulleys, and re-tension. A belt routing diagram (often on the deck or in your manual) is essential.
• Common gotchas: Double-check belt routing before tightening—wrong routing causes rapid wear or blade disengagement. Also, the tensioner spring can be stiff; use a wrench to relieve tension. If your old belt was frayed, inspect pulleys for rust or debris.
• Brand note: Troy-Bilt sells this as a compatible replacement; it’s not OEM but meets the same specs. Reviews (4.4/5 from 4,500+ buyers) indicate it fits most listed models without modification.

Should You Buy It

Buy this if you need a reliable, durable replacement for a 50-inch deck on a Cub Cadet, MTD, Troy-Bilt, or Toro tractor listed above, and you want aramid strength without paying OEM prices. It’s ideal for regular mowing and tough conditions. Skip it if you need an OEM belt for warranty compliance or if your deck is smaller or larger than 50 inches.
