The best corn we harvested last year in Western Kansas did 240 bushel per acre. Our 9610 Deere went about 4.5 mph with an 8 row head at probably 18% moisture. I was in a lexion 480 once an it ran 6 mph with a 12 row head. The monitor showed about 2700 bushel per hour at 21% moisture and a yield of 200 bushel per acre. Sebas, if you are so curious about all those things here, why don't you go on a harvest crew here for a seasonIJ
