We grow a lot of 6 row barley and Canola and both seem to be bad for losses over the sieves on our 460's. I've tried messing with the windboard but can't make anything of it. Also the 3D seems reluctant to keep the grain in the combine even on a slight side slope, and I don't think that it's due to false readings either as we always have plenty of green stripes in our fields after harvest. Also any ideas to improve the spread pattern of the choppers in damp (Scottish) conditions. TIA Col
