Ran the combine today for about 10 acres. Kept counting around 20 kernels per foot on the ground behind the sieves. nothing to speak of outside the the sieve area. Great yield around 80 bushel. Heavy straw is good thrashing wheat. Around 17% moisture. The srtaw is ripe though. Pretty sure it is rotor loss because I open the sieves all the way up and the kernel count didn't change. Rotor around 1050 to 1100. concaves are tight. I have it on 3 with the new 21version numbers. I tried speeding the rotor up to 1150. Tried the clearance at 2 then I started to smush kernels. How do I get rid of rotor loss?
