Deck Belt Compatible with MTD Cub Cadet Troy Bilt Toro XT1- GT50 LT50 XT2-LX50 LX500 SL500 CYT5023SE G8300 T260 50 Inch Deck 754-04077 954-04077 112-0332

What It Is

This is a 50-inch deck drive belt for select MTD-built lawn tractors and zero-turn mowers. It transfers power from the engine pulley to the blade spindles, enabling the cutting deck to operate.

Fitment & Compatibility

Before buying, confirm your mower has a 50-inch deck (measure blade tip to blade tip). This belt fits models like the Cub Cadet XT1 GT50, LT50, XT2 LX50; Troy-Bilt TB30B, TB42; and Toro T260. It replaces OEM part numbers 754-04077, 954-04077, and 112-0332. Measure your old belt’s length (approx. 136.5 inches) and width (1/2 inch) to verify. Check your deck’s belt routing diagram—this belt uses a serpentine path around three spindles and two idler pulleys. Not for 46-inch or 54-inch decks.

Key Things to Buy

• Quality: Aftermarket belts (like this one) are often reinforced with Kevlar or polyester for longer life than OEM. Look for aramid cord construction.
• Installation: Moderate difficulty. You’ll need to remove the deck (2 pins or bolts) and release the idler pulley tension. A belt routing diagram is essential—take a photo before removing the old belt.
• Common Gotchas: A loose or misrouted belt causes blade slippage or uneven cut. If your deck has a spring tensioner, ensure it’s not worn. Check pulleys for debris or damage first.
• Durability: Expect 1–3 seasons under normal residential use. Frequent engagement/disengagement or wet grass will shorten life.

Should You Buy It

Yes, if you need a reliable, cost-effective replacement for a 50-inch deck on an MTD-style tractor and you’re comfortable with a basic belt swap. It’s a solid alternative to pricier OEM belts, with good ratings for fit and durability. Skip it if you have a different deck size or want a premium OEM part.
