Farm-tested. Farmer-trusted.
Razors Edge® Conaves

Change Crops. Not Concaves.
Harvest is busy enough. Razors Edge gives you one concave system for multiple crops, helping eliminate unnecessary changeovers and keeping your combine where it belongs—in the field.
BUILT DIFFERENT. HARVEST BETTER.
Razors Edge uses a unique variable spacing design that's tighter where the crop first hits and progressively opens as material moves through the rotor. That means strong threshing up front with plenty of room for material to flow and grain to separate—helping reduce overload, plugging and grain loss.
VARIABLE SPACING
Threshes where you need it and opens up where you need flow.
GRAIN-ON-GRAIN THRESHING
Notched bars promote grain-on-grain action for effective threshing with less crop damage.
NO COVER PLATES
Designed to give you the threshing of a small wire with the flow of a round bar—without the hassle of cover plates.
ONE MULTI-CROP SYSTEM
Go from corn to soybeans, wheat, barley, canola and more without changing concaves.
