Its that time of year again, and I am pulling my hair out trying to set my R62 for canola. As of right now I am running my rotor at 800 , chaffer at about 3/4 open and the lower sieve at about 3/8". Fan is at 6.5. I seem to be loosing it out the sieves and am not sure what else to try. Just looking for any help I can get. Wondered about trying less wind. I usually run my wind at about 6.5-7. Seems like it takes lots of air to stir things up in the back end, otherwise with seeds just ride out in the pod(my experience from past years. I am also travelling at 3.5 mph. possible too fast?
