Just curious what guys are using for settings in spring wheat and canola?? Rotor speed, concave clearance, fan, sieve #. Out of curiosity what number are you using for the grain loss calibration factor?? New to running a green machine so open to different configurations.
9870 sts settings

This is what worked for canola last year on a 9770.
Feed accelerator on slow.
Top sieve 16
Bottom sieve 3
Fan 670
Concave 14
Rotor 420
These settings were on a thread last year. The idea being that you don't want to grind up the straw and overload the sieves, so the slow accelerator and the tight concave. The tight concave augers straw out the back rather than letting it churn and break up. The combine was unhappy in a tough canola swath so I opened it to 27 until I was past the tough spot. The yield monitor said I picked up 3 bushels per acre at a concave clearance of 14 compared to 27. The trouble is, I read about these settings on the morning of the last day in canola.

Had our 9870 in some flax for the first time this year. I could not keep it out of the return! I did everything I could think of and it still plugged. Dang near drove me crazy. I was just glad I didn't have all that many a acres of it. Combine was limited to 2.5mph in 800lb flax harvested with a stripper header. In my mind, Ishould have been able to go much faster.
9770
Wheat
Feeder house slow and accelerator slow
rotor 950
concave 12
fan 1000
chaffer 15
sieve 6
fillers in 1&5
Cutting 35 feet at 5mph in 55bu muchmore wheat knee high straw.
Lift you chopper and check straw open concave till you start leaving seed in heads then close down till good. I use a drop pan to check for loss not just run behind with a shovel not a true check.

Concave bring closed tighter than 8 mm leads to heads/pods going between the threashing elments and not getting rubbed out. Running loose fast and full and utilizing grain on grain threshing really helps productivity in most conditions
