How tight did you bring up front of concave to solve flax and wheat thresh with three filler bars and wide rasp barsIJ I would prefer all forward wide rasp as long as you can make it work up to your standards. You may want to consider seperator grate covers or building up approx every other wire in seperator grate for barley loss and grinding canola straw ect. You didn't say what year you got so just be sure it is new enough to have extended cylinder bars to discharge and feeder shocks. If not get them installed and also get third helical from gearbox extended over top left corner of feeder opening. Be sure if you run discharge beater to have good knotched blades outward. Congradulations, Merry Christmas, and good luck.
