I know nothing about MF combines but 4.3 kph seems slow,concave under loaded?@Badshot
Now that the barley volunteers are coming through, I've noticed that I've left a few green stripes with my new Centora..
I had the drum speed at 1,100 rpm, concave at no.3, RS at closest gap (35mm), curtain as recommended and travelling at 4.3 kph.
Am fairly sure they are walker losses as chaff spinner was on.
I've got to be doing something wrong, but I can't quite put my finger on it.. Any ideas?
