We have been combining canola a couple of days now with little losses on L130 canola. Moved over to 252 canola last night and losses were way more and can't seem to set machine right. 252 straw is way tougher than the L130. Combine settings are 680 rotor, 700 wind, 18 concave,12 top,8 bottom, spreader @530. Concaves are hard thresh, small wire and 2 large wire.Canola in 30' swaths 20 days swathed, 45 - 50 bushels am traveling 3.5 to 4.5 mph. What other changes in my settings should I try?
