Hmmm, Harold, its hard to adjust a "9960" JD CottonPicker to do a good job in corn. Please verify correct STS model and header sizeIJ Assuming this is a typo err and actually a 9660 STS suppose the concave is too tight, breaking up cobs. lower sieve or chaffer may also have holes or be breaking apart if separator hours are over 1500 to 2000. Do you have a fixed or adjustable pre cleanerIJ Might need to be sure side screens are in place and fan speed is up to 1400 rpm to keep the leaves out of the clean grain sample. Good luck.
