Confused with your first sentence. First of all, you talking about the header or the combine top link? Nevermind, you must be referring to the lateral tilt running centered on 50, while auto contour is active...good luck!!!!
(All the more reason I wish Claas had a tilt bias adjustment)
Ground pressure, never used it, don't really have a small header that runs on wheels. Wouldn't the adapter springs need to be set tight so the header doesn't carry so much weight? The more I think about it, don't see how it would work. For ground pressure to work, wouldn't the two sensor potentiometers need to be fully compressed. The header would be dragging pretty hard, and how would it know when to tilt?
Feeder faceplate averaging centered. Iím not even sure it would be any advantage to average centered, it just should!
Every agjustment I was making involved running right on the ground, no research on wheels/off ground yet.
However, I disagree with your premise, it appears so little weight change can be sensed by Claas in the cylinders it would work mid spring range where one may normally operate MacDon float.
Recent scale testing I did shows, and Iíll take a middle/middle reading (B and a half tilt, 2 header height) was, well, Iím going to guess youíve never seen this, so...
So, 370 kg everything in the middle.
Maybe Claas cylinder sensing could run even lighter and more consistent than normal header operation? Header angle differences compensated for?
Simply donít know.
These figures were relatively repeatable but stiction in all the joints may cause slight variance, keep in mind all these readings taken header running all functions at engine idle.
