THE PROBLEM:

VOLUNTEER YIELD, CRACKED GRAIN, DIRTY SAMPLE, CHANGING CONCAVES

One big reason for aftermarket combine concaves, rotor loss. This loss results from incomplete threshing, lack of capacity, and an overloaded separation section from stock concaves and grate assemblies. The problem happens because stock concaves are not open sufficiently to get enough threshed grain down and onto the augers and thus, overloading the separation grates from the volume of grain coming in. The overloaded separation section is then unable to capture all the threshed grain so it ends up being “thrown over the rotor” and spit out the back. This results in volunteer yield you see to the right. The higher the yield, the more chaff there is or the harder the crop is to thresh the WORSE the grain loss is, also known as “volunteer yield” as you can see.

THE SOLUTION:

XPR 3 CONCAVES

Over 3 years, that’s $118,440 lost on 1000 acres of soybeans. Our XPR aftermarket concave system is engineered from years of knowledge and experience. The research and design that went into our concave system is nothing short of impressive. Every single element of the concaves and separation grate was engineered to maximize threshing effectiveness and separating and capture threshed grain without any rotor loss. The XPR concave system’s bar helps keep the rotor full for maximum material-on-material threshing. The bars also boast 135% more threshing surface area than stock round bar concaves. Altogether, this enables our system to thresh more effectively and to get crop threshed sooner. By threshing more completely and sooner, we have more threshed grain sooner and get significantly more grain out in the first and second concave. Furthermore, our system is more open so we get more grain out in the concave section apart from separating it sooner. This prevents overloading the separation section and by getting more grain down onto the augers sooner we stop the rotor loss. Lastly, besides putting more in your tank there are countless other benefits to the system like no changing concaves or having to purchase two sets or having excess dockage or piles of dust in your bin from cracked and split grain. The return on this system is phenomenal and there is no better investment for your combine.
