  • Description

    The Copperhead Concave Systems 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.
