What It Is

This is a 50-inch deck drive belt (5/8" x 134") for select Cub Cadet, MTD, and Toro lawn tractors. It powers the blades on mid-size residential mowers with fabricated or stamped 50" decks—commonly found on the Cub Cadet XT1 LT50, LT1050, and similar models, as well as Toro GT2100/GT2200 series.

Fitment & Compatibility

Check these three things before buying:

1. Deck size & belt length – This belt is 5/8" wide and 134" long. Measure your old belt or confirm your deck is exactly 50". A 48" or 54" deck will not work.
2. Model number cross-reference – It replaces OEM parts: Cub Cadet/MTD 954-04077, 754-04077, 754-04077A, and Toro 112-0332. Verify your machine’s model number from the list (XT1 LT50, LT1050, SLT1550, LTX1050, LGTX1050, Toro GT2100, GT2200) or check your owner’s manual.
3. Aftermarket vs OEM – This is an aftermarket aramid belt, not a genuine Cub Cadet part. It’s dimensionally identical but may differ slightly in material feel. If you have a tight belt path or pulleys with wear, OEM belts sometimes last longer.

Key Things to Know

• Aramid construction – Stronger than standard rubber belts, resists stretching and heat better. Good for heavy grass or frequent use.
• Installation difficulty – Moderate. You’ll need to remove the deck, release tension from the idler pulley, and route around three spindles. A diagram helps—snap a photo before removing the old belt.
• Common gotcha – If your old belt was frayed or smoking, check all pulleys for debris or seized bearings. A new belt on a bad pulley will fail quickly.
• Warranty note – Aftermarket belts usually carry a 1-year limited warranty. Genuine Cub Cadet belts may have longer coverage.

Should You Buy It

Buy this if you need a direct replacement for a worn 134" deck belt on a compatible 50" Cub Cadet or Toro mower and want aramid strength at a lower price than OEM. Avoid it if you have a different deck size, need a genuine OEM part for warranty reasons, or if your pulleys show signs of damage—fix those first.
