Float Calibration

The lift cylinder pressure sensor must be calibrated for each header installed on the combine in order for Active Header Float to function Properly

Prepare Header for Calibration:

  • Turn the key switch to the run position.
  • Hook up header to the combine and ensure header harness is connected to the combine harness.
  • Move the machine onto a level surface.
  • Raise header completely.

While in this mode, the feeder house may be moved in open loop control.

With the header lift switch on the multi-function handle, lower the header until the cutterbar is about 100 mm (3.94 in.) above ground level (the header must not touch the ground).
