We run three cover plates on the first two concaves in wheat with the rotor as far up as possible. Also It seems to help with cardboard running the length of each cover plate. Great smaple in 115 bpa wheat
When you talk about using cover plates in wheat, are you leaving large wire concaves in and using cover plates, or are you putting cover plates on small wire? Last year i ran one small wire in front and then two large wire, and i thought it did pretty well.
