Description

When your alternator starts squealing or your temperature gauge starts climbing during a long day in the field, chances are your fan and alternator belt has stretched, cracked, or glazed over. This belt keeps two critical systems running—your cooling fan to prevent overheating and your alternator to keep the battery charged and electrical systems working properly. Without a good belt, you’re looking at an expensive breakdown right when you need your tractor most.

What You’re Getting

  • Proper 55.33-inch effective length designed specifically for these John Deere models
  • 11/16-inch (0.6875″) width provides the right grip and power transfer
  • Durable construction that handles the constant flexing and heat cycles of engine bay operation
  • Direct replacement that fits your existing pulleys without modifications

Built for Real Farm Work

This belt fits a wide range of John Deere tractors from the mid-size 2000 series utility models through the larger 5000 series machines, plus the 3830 windrower. Whether you’re running a 2355N with fixed fan setup, working hay with a 2755, or cutting with a 3830 windrower, this belt handles the demands of daily farm operation where reliability isn’t optional.

Made to Last

Farm belts face temperature extremes, from cold winter startups to hot summer days under load. This belt uses quality materials that resist cracking from heat cycles and maintain flexibility in cold weather. The construction is designed to handle the side loads and vibration that come with tractor operation.

Good to Know

Replacing this belt is straightforward on most models—just release tension, slip off the old belt, and route the new one properly. While you’ve got the belt off, check your pulleys for wear or rough spots that could damage the new belt. A quick tip: mark or take a photo of the belt routing before removal to make installation easier.
