Calmer Corn Heads, Inc., is ready for harvest this year with a 6-tooth gathering chain drive sprocket retrofit for John Deere 40 and 90 Series corn heads.

The replacement for the stock 8-tooth sprocket reduces chain speed and wear by 25%, and allows a similar percentage increase in stalk ejection – meaning less trash intake.
Company officials say improving chain lug synchronization to ground speed will also boost harvest efficiency and the ability to harvest downed corn.
