954-05027A Drive Belt for Cub Cadt MTD Troy Bilt Craftsman XT1-GT50 XT1-GT54 XT2-GX54 T8400 Replaces 954-05027B 754-05027A 754-05027B (1/2" x 91")

What It Is

This is a replacement drive belt (1/2" x 91") for select Cub Cadet, MTD, Troy-Bilt, and Craftsman lawn tractors. It transfers power from the engine pulley to the transmission, enabling forward/reverse movement. Designed for specific XT and T series models with 50" or 54" decks.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: Fits 50" and 54" decks only (models XT1-GT50, XT1-GT54, XT2-GX54, T8400).
• OEM part numbers: Replaces 954-05027A, 954-05027B, 754-05027A, 754-05027B. If your original belt ends in a different number, measure yours.
• Physical dimensions: Must be exactly 1/2" wide and 91" long. Measure your old belt (lay flat, measure outer circumference) to confirm. Aftermarket belts may vary slightly in length—check reviews for fitment reports on your specific model.

Key Things to Know

• Quality vs. OEM: This $8.71 aftermarket belt is cheaper than OEM (typically $20+). Expect similar lifespan for residential use, but may wear faster on heavy-duty or frequent mowing.
• Installation difficulty: Moderate. You’ll need to remove the deck or at least the belt cover, release tension from the spring-loaded idler pulley, and route the belt per your mower’s diagram. No special tools required.
• Common gotcha: If your mower has a separate deck belt and drive belt, confirm this is the drive belt (not the deck belt). Deck belt length will be different.
• Check pulley condition: Worn or damaged pulleys will shred a new belt quickly. Inspect all pulleys for cracks, rust, or wobble before installing.

Should You Buy It

Buy this if you have a compatible Cub Cadet, MTD, Troy-Bilt, or Craftsman XT/T-series tractor with a 50" or 54" deck and need a budget-friendly replacement for residential use. Skip it if you need OEM-level durability for commercial mowing, or if your belt measures anything other than 1/2" x 91".
