Also, if you do a good calibration, and the combine tries to slam the header down when you want it to automatically lower, is the header drifting up while it is in the air? You don't want the header to drift up on its springs while automatically lowering. When it does, the combine thinks the header has made contact with the ground, even though it hasn't. Then when the header drops again from its springs, the combine tries to slam it down because it isn't sensing any ground. This can be fixed by reducing tension on the four large springs. I assume you are preparing for wheat, so you won't need much tension anyways.
I dont think I have too much tension, but being that my header raises fast and i cant slow it down, it definitely bounces a bit at upper limit.
I talked with Jeff both yesterday and today and hes been incredibly helpful, but as he mentioned to me, I may have to fix the rate of drop/raise before I can even get the calibration and other settings right.
Im uploading a video now of how the header jumped and my header CAC sensitivities. After talking with my dealer tech, we adjusted my top line down to -35 and the bounce was eliminated. It really felt to me like the hydraulic flow was just much more than the machine expected while trying to find the perfect height...like as oversensitive autosteer or a rate controller that oscillates.
Main thing is that its picking now, or would be if not for unrelated issues, so i can get by for what little wheat i have.
Talked with my tech this afternoon about both directions being too fast and he still thinks its the accumulators. Tonight while looking up something else, I came across this in the service records. Im wondering if this previous valve leak could be the root cause.
