Getting ready to do some wheat with the 8820 T II in a couple months. Does anyone have some rule of thumb settings for things like fan speed, cylinder speed & concave setting? I have heard that ~ 1100 RPM on the cylinder, and max on the fan speed, which is probably also about 1100 rpm then adjust the seive to minimize loss....( I have an air foil seive/chaffer) Also with a 30' header and hoping the wheat goes 40 bu/ac, what kind of speed can I look to be running at? Thanks
