In response to the suggestions for my 9600. the inserts are removed, have tried concave close 1-2 or 8-12 on the digital concave display and have varied the cyl. speed from 330 to 420. helps some, but combine surges @ lower cyl. speeds . closing concave helps that problem, but straw breaks up and still traps beans (problem varies much by bean variety). flexhead feeds fairly well except sometimes on lefthand side,then lose is worse. I have had this problem in drilled beans also W_ even feeding, very puzzling for me . note. if I increase speed then lose goes high and my grain lose monitor pegs to the right even at amoderate setting. Thanks...
