No, in my opinion in the closed grate F's all one has to do is add more concave bars if more threshing is required. We had excellent results in lespedesia and clovers with the bars over the std. Maybe Durham wheat or some other crops might be a question. I feel the most important thing is when the bars are welded up the FRONT EDGE must be hard surfaced. A standard hard surfaced bar will have the softer leading edge erode and leave a sharp tit leading edge and this can spear grain and cause some damage.
