west central ohio | I always tried exactly what all the posters on here said by tightening up the concaves, and speeding up the rotor. But I had my uncle run circles around us every year with a 1660. So I started paying attention to how he set his combine up in green stem tough beans. He would open the concaves wider than most would be comfortable with (like for corn), speed the rotor until you start cracking things, then back it down a fuzz, then drive fast enough to load the rotor heavy. Its not for the faint of heart, but that little combine would just eat with a 22 ft head. Obviously you always check to make sure you are getting everything out, but generally even with green stems, the beans and pods open easy. It has a AFX rotor, with std bars in the front, and spiked bars in the bk. The highest capacity of the axial flow is found with even feeding, and the 1020 feeds best when its stuffed full continuously, plugging always happened to me when things start to hang. I also found extra capacity this year in my 1680 by adjusting the rock trap beater blades to the smallest setting, or completely recessed. The concave setting is a balance of giving the crop room in the rotor, and also keeping things full enough to thrash out tougher pods. You might try to narrow up your cut, if you feel your working things too hard, by hanging some of the header out of the crop, and increasing ground speed. It may get your feeding to improve by stuffing the part of the header that is still doing the cutting. Hope this helps.
