In good corn, 180-200 bu., You will be pushing the capacity of that JD 6620. Really pushing if you have any slopes and or high moisture. The JD 6620 was a perfect 4 x 38 machine but 6 x 30 will make you run out of chaffer capacity on slopes and straw walker area in heavy fodder corn. In really good corn 2-2.5 mph may be all you will get out of this machine but that is still going to give you good bushels per hour.
The JD 216 bean head will be no trouble. Many run JD 220 head without issues in soybeans.
