Description

When the corn head’s chain drive starts acting up, the idler sprocket is often the culprit. This 8-tooth sealed idler keeps your chain running smooth and properly tensioned, so your header can move corn stalks into the gathering chains without a hitch. If you’re hearing chain noise or noticing uneven feeding, this little sprocket might be just what you need to get back to steady harvesting.

What You’re Getting

  • 8-tooth design that fits #60 chain systems in your corn head drive
  • 5/8″ bore size for standard mounting shaft compatibility
  • Sealed construction keeps dirt and debris out of the bearing surfaces
  • Direct replacement part—no modifications or adapters needed

Built for Real Farm Work

This sprocket fits John Deere 40 and 90 series corn heads up to serial number 466450. Whether you’re running a 6-row or 8-row setup, these heads see plenty of action during harvest season. From early morning dew to dusty afternoon runs, this idler keeps things moving smoothly when you’re pushing through acres of corn.

Made to Last

Corn harvest is tough on equipment, and chain drive components take a real beating. This sealed idler sprocket is built to handle the constant motion and debris that comes with cutting corn. The sealed design keeps the bearing surfaces protected, which means longer life and fewer breakdowns when you need your equipment most.

Good to Know

Installation is straightforward—just remove the old sprocket and slide on the new one. Check your chain tension while you’ve got things apart, and take a look at the other idlers and drive sprockets. If one’s worn, others are probably getting close. Keep a spare on the shelf—there’s never a good time for a chain drive failure in the middle of harvest.
