Hello IAFarmer, I was cutting seed beans today for Garst. They are mid group 4 and was at 14.5% about 35bpa, I had my TR-98 set as follows, concave at 4-5, rotor rpm at 750-800, fan at 840. I have round bar concave also. Beans look good. I would not cut them to green as a New Holland will do a very good job on dry beans anyway. Did you get your chopper to work betterIJ Wish you a good harverst.
