Calibrating Feeder House – John Deere S7 Series
Feeder house calibration must be done before header calibration.

setup and calibration are complete, adjust center-link back to desired header angle. For instructions, refer to the header
operator’s manual.
NOTE:
Changes may have been made to the combine controls or display since this document was published. Refer to the combine
operator’s manual for updates.
