no tricks should be required. Per op man run the concave as close as possible until the hp requirements go up, make sure grate is level, raise the front concave a couple of marks toward minimum, RPMS up til crackage occurs then back off a tad, and then add filler strips to the concave if necessary. You add them in til it will get 100% threshing in any crop I know of. On the 5 series the adjustments are all push button. Make sure the settings are RIGHT on the readouts and that they have been 'zeroed in' during predelivery. Most I have checked have been off a tad. It could read a setting of 1 on concave clearance and actually be a 3 or 4. Same way on fan choke. Check it out.
