954-04044A Riding Mower Lawn Tractor Deck Belt with Kevlar Cord Replaces MTD 954-04044A 754-04044A Fits for Cub Cadet RZT-22 RTZ-50 Troy-Bilt Mustang XP 50 Craftsman ZTL7000 Zero-Turn Mowers

What It Is

This is a replacement deck belt for zero-turn and riding mowers, specifically designed to drive the mower deck blades. It uses Kevlar cord reinforcement for extra durability and is a direct aftermarket replacement for MTD OEM part 954-04044A and 754-04044A.

Fitment & Compatibility

• Deck size: Fits 50-inch cutting decks (verify your deck measures 50 inches from blade tip to blade tip).
• OEM numbers: Replaces MTD 954-04044A and 754-04044A. Cross-check your current belt’s part number.
• Brand/models: Cub Cadet RZT-22, RTZ-50; Troy-Bilt Mustang XP 50; Craftsman ZTL7000; and other zero-turns using a 50-inch MTD-style deck.
• Measure before buying: Lay your old belt flat and measure the outside length. This belt is approximately 92.5 inches long (common for 50-inch decks). If your belt is longer or shorter, this won’t fit.
• Aftermarket note: Not an OEM Cub Cadet belt, but matches OEM specs. Check belt width (typically 1/2 inch) and that your deck uses a single belt for all blades.

Key Things to Know

• Installation difficulty: Moderate. You’ll need to remove the deck or at least the belt shield and mule drive pulleys. A belt routing diagram is helpful—snap a photo before removing the old belt.
• Kevlar cord: Adds resistance to stretching and snapping compared to standard rubber belts. Good for heavy grass or frequent mowing.
• Common gotcha: The belt may feel tight on new pulleys. If it won’t seat, check that you’re routing it correctly around all idlers and spindles. Forcing it can damage the belt.
• Noise: Some users report slight squeaking during first use—this usually stops after a few minutes of running.

Should You Buy It

If you own a 50-inch zero-turn with an MTD-style deck and need a reliable, budget-friendly replacement for a worn or broken belt, this is a solid choice. The Kevlar cord adds real longevity, and the price is fair for the build quality. Skip it if you prefer OEM parts for warranty reasons or if your deck uses a different belt length or width.
