Running a 2366 with large wire concaves have slotted and keystock grates. Going to combine some rye grass and some wheat. Have large wire concaves in. I only have a couple of custom jobs to do so i don't want to put a set of small ones in. I put slotted grates in for oats wondering if they would work for the grass and wheat. Don't have cover plates and don't know any thing about them. Do mostly corn and beans. I have harvested grass and wheat with the large wires and no cover plate but the sample isn't real pertty. Any help would be great thanks!
