Copperhead Concave System


  • Compatible with John Deere & Case IH Combines
  • Notched Bar Design
  • Universal Crop Design
  • 135% more threshing surface area (compared to OEM model)
  • Includes disrupter lugs


The Copperhead Concave System utilizes notched bars for restricted flow. This allows more material in the concave area, increasing grain on grain threshing.  As grain moves along the system, the concaves are progressively open, leading to increased unloading of grain as it’s threshed.
With the Copperhead Concave System, you can thrash in any crop in any condition, have cleaner samples, decrease field time (resulting in less fuel cost), and stop rotor loss.


  • Eliminates Rotor Loss
  • Increase Capacity in ALL CROPS
  • Decrease Grain Damage (less cracks, splits, and broken cobs)
  • Decrease Fuel Consumption
  • Cleaner Grain Sample
  • Eliminate changing concaves for different crops
  • Increase harvested bushels/acre
  • Run combine on slower rotor speed
  • Unloads the concave quicker
  • 10% threshing improvement (compared to round bar design)

Benefit Details

Rotor loss is caused by a congested separation section. OEM concaves lack the ability to unload enough grain, causing an overloaded separator. Therefore, thousands of bushels are spit out the back. Combine manufacturers recommend speeding up the rotor and slowing down in the field. However, this does not solve the rotor loss issue and causes more damage to the crop.
