Do you use large or small wire concavesIJ Do you have all the wires installed or not. The thing that bugs me is for us to get a good sample we have to install all of the concave wires for soybeans other wise I get to many pods in the tank. But I have to have everyother one removed for corn other wise rotor loss goes way out of site. (I only remove the wires from the first two concaves) So would I be able to use the cover plates in soybeans instead of installing every wire in the concave, and in turn maintain a good sampleIJ If so how many cover plates does a person installIJ Forgot to add this is a short shoe 1680, large wire concave, keystock grates, standard rotor. thanx for any help Brad NC.
