How often have you looked at your combine's concaves after (or mid) harvesting and saw that they were plugged - much like the top view of the image? This plugging predicament is causing frustration for many farmers, as it prevents the threshed grain from falling through the concaves. This means that more grain is carried rearward along the rotor, often overloading the separating capacity and creating rotor loss. Moreover, grain that falls farther back along the rotor puts extra stress on the combine’s cleaning system to further reduce capacity. Plugging can be more common when harvesting high moisture crops, but doesn’t need to be tolerated any longer. KX7 concaves (pictured in image) are here to help!
The design and angle of our MaxRoundTM KX7 concaves promotes efficient crop flow and minimizes the opportunity for hairpinning through the concave bars. This means you can continue harvesting without stopping to unplug your machine. You can continue capturing high yields and clean samples. And, you can continue taking control of your harvest!
The below pictures were taken in a side-by-side field test with two John Deere S680 combines harvesting 28% moisture corn in the same field. One was running KX7 concaves with one MaxThreshTM assembly in front, followed by MaxRound assemblies. The second combine used traditional style aftermarket concaves. While the manufacturer of these competing concaves claims to reduce plugging, the photo clearly reveals a significant problem.
