i will tell you my settings i use on wheat and durum, pre seive...5
rotor 900 to 1000
concave 2 - 4
fan 950 to 1050
upper seive 11 to 14
lower seive 5 to 7
no more fan plugings and clean sample, takes it to almost seed quality and return might bounce high on factory preset sensity,
combine is running less than .5 percent out the back in 50 to 70 bu yeilds
now for conala or mustard i run
pre seive 2
fan 650
rotor 670
upper seive 7
lower seive 6
concave 25
clean sample with no fan plugs and minimal out the back in A 30 to 40bu crop
last night we ran in a 81bu/ac canola crop
preseive 2
fan 480
rotor580
upper seive 11
lower 8
concave 25
sample was dirty in my books but owner was happy with the results out the back, figured it would be 4 percent dockage at the terminal, we did find the the previous settings were to high for his 25foot swaths
this canola crop was the heaviest canola crop i have ever been in and it was on irragation
i run small wire on the front and large wire on the back, conditions seam to change from machine to machine, but stay with it
i run with two 9860s jds and run at least two mph faster with a bigger head, no comparsion, like apples and oranges
