Concaves from Cooperhead Ag Products - a way to harvest ALL crops with one set of concaves!
Available for both John Deere and Case IH combines. This is the John Deere-compatible version. For the Case-compatible version, click here.Fits:
This is the original Concave System that was designed by Donnie Estes from Frankfurt Indiana. The OEM John Deere and Case round bar concave is made with 5/8″ bars and 5/8″ spacing. The Copperhead Concave System is designed with a 68% larger opening. The extra space between the bars allows you to unload threshed grain in the Concave section of the combine, rather than carrying it all the way through to the separating section, which overloads the separator. The main reason for rotor loss is overloading the separating system.
The machined, 90-degree, hard-surfaced, notch on the face of the bars, restricts the flow. Restricted flow forces the grain to thresh quickly, keeping the machine from overloading the separating section. This system does not require the concave to be full to get the grain to thresh properly, the restricted flow is what gets the crop to thresh properly.
The third concave in this system is a separating concave. No threshing happens in this section, due to increased threshing in the first two sections with the notched round bar. Having a separating concave is, again, critical to unloading threshed gain from the system to decrease the overload of the separating section.
The Copperhead Concave System uses three cover plates. Two in the first concave and one in the second concave section. The cover plates are completely adjustable and/or removable, which is what allows you to harvest any crop with the same set of concaves! With the ability to easily adjust the system, you will be able to dial in close to ZERO rotor loss.

Evan (with Precision Agri Services, Inc.) has been great to work with. Everything he told me he followed through on in a very timely response. Their product knowledge and support have been great.
Slight hills were drawing it down at C3 at around 10.0 mph going down to as low as 9.0. After the tune with AgroEcoPower we were in D1 at 12.2 mph and no draw down whatsoever.
Within thirty seconds I knew you knew what you were doing. I have no patience and I know if I call, I will get an answer. Product knowledge and service is everything.
Evan (with Precision Agri Services, Inc.) did a great job presenting me with options on a steering system I was not satisfied with. He helped me use Ag Leader technology I Already had to Convert it to steer my 8520 John Deere. Tech support is top-notch with him.
We had our 8320 ECU rewritten and are so happy we did! Tanner took the tractor from 260hp up to 305hp and it is a world of difference. We are pulling our digger faster at less rpm and can't wait to see what it will do on our vertical till!
Just put it (Ag Leader InCommand 1200 with ISO serial bridge) to the test. Everything works really well. Each boom sections on and off, in and out of multiple different paint zones. Pretty sweet deal!

This little workhorse just gained a few more horses [with AgroEcoPower]. I use this utility tractor for just about everything now the tractor has some more added power to complete my tasks. Stock HP: 36hpTuned 48hp with AgroEcoPower.
