Description
When you’re watching corn stalks march through your header at harvest, the last thing you want is a worn drive sprocket causing chain skip or jamming up the works. This 8-tooth upper drive sprocket keeps your corn head’s drive system running smooth and steady, transferring power right where you need it to keep those row units feeding evenly.
What You’re Getting
- Cast iron construction that handles the constant loading and vibration of harvest season
- 1-inch hex bore for secure mounting and positive drive engagement
- Heat-treated finish adds durability and wear resistance for long service life
- Direct replacement design—no modifications or adapters needed
Built for Real Farm Work
This sprocket fits right into the drive systems you’ll find on John Deere corn heads, where it transfers power from the main drive to operate gathering chains, snapping rolls, or other row unit components. Whether you’re running through 200-bushel corn or dealing with tough, dry stalks late in the season, this sprocket maintains consistent power delivery to keep your header working efficiently.
Made to Last
Corn harvest puts drive components through their paces with constant starts, stops, and varying loads as you encounter different field conditions. The cast iron construction handles these stresses better than lighter materials, while the heat treatment process adds surface hardness that resists wear from chain contact and debris.
Installation Notes
This is a direct replacement that mounts on the existing 1-inch hex shaft. Check your chain alignment and tension while you’ve got things apart—proper chain setup prevents premature sprocket wear and keeps everything running quietly.
