954-04083 754-04083 Mower 5/8 x 136 Inch Deck Belt for Cub Cadet/MTD/Troy-Bilt GT1054 GTX1054, Grasshopper 382084, Husqvarna 539109243 Razor Z248F RZ4824F Z4824 EZ4824 48" Zero Turn Mower (Aramid)

What It Is

This is a 5/8-inch wide by 136-inch long deck belt designed for 48-inch zero-turn mowers. It transfers power from the engine pulley to the mower deck spindles, driving the blades. It’s a direct replacement for OEM part numbers 954-04083, 754-04083, and several cross-referenced models.

Fitment & Compatibility

Before buying, verify two things: deck size (must be 48 inches) and belt length (must be 136 inches, not 135 or 137). This belt fits specific Cub Cadet, MTD, Troy-Bilt, Grasshopper, and Husqvarna zero-turn mowers including:

• Cub Cadet GT1054, GTX1054
• Husqvarna Razor Z248F, RZ4824F, Z4824, EZ4824
• Grasshopper 382084

It is an aftermarket belt made with aramid fiber, not OEM. If your mower uses a different OEM number (e.g., 954-04082 or 754-04084), this belt will not fit. Always measure your old belt’s length and width before ordering.

Key Things to Know

• Aramid construction is stronger than standard rubber but can be slightly stiffer initially—expect a short break-in period.
• Installation difficulty is moderate—you’ll need to release deck tension by removing a spring or loosening a pulley, but no special tools are required.
• Common gotcha: Some users report belt squeal for the first few hours if tension is not set correctly. Check belt routing diagram for your model before installing.
• Price vs OEM: At $24.99, it’s typically 30-50% cheaper than a genuine Cub Cadet or Husqvarna belt, but may not last as long in heavy commercial use.

Should You Buy It

Buy this belt if you need a cost-effective replacement for a 48-inch zero-turn mower and you’re comfortable with aftermarket parts. It’s a solid choice for homeowners or light commercial users. Skip it if you require OEM guaranteed fit or if your mower has a different deck size or belt length.
