I would have to disagree, theshing wheat with filler plates in is very slow, poor feeding, and takes alot more HP. 1_2 the farmer do not even put them in for corn around here (but it is all n2 corn and most goes to gas plants). It also seems that the round up beans with green stems go through better without the filler plates in. Now this is in eastern ND, and the conditions in your area could be completely diferent.
