4.15 John Deere 60 Series Combines
To make your header’s auto header height control (AHHC) system compatible with John Deere 60 Series combines, you
must check the height sensor voltage range, adjust the header height response rate and drop settings, and calibrate the
AHHC system to ensure that it is working correctly.
4.15.1 Checking Voltage Range from Combine Cab – John Deere 60 Series
To ensure that the auto header height control (AHHC) system on your header works correctly with your John Deere 60
Series combine, the output voltage from the header height control sensors must be verified.
The auto header height sensor output must fall within a specific range, or this feature will not work properly.
NOTE:
Changes may have been made to the combine controls or the display since this document was published. Refer to the
combine operator’s manual for the most up-to-date information.
DANGER
Check to be sure all bystanders have cleared the area.
1. Position the header 150 mm (6 in.) above the ground and unlock the adapter float.

2. Ensure that the float lock linkage is on the down stops at
both locations. When the linkage is on the down stops,
washer (A) and nut (B) cannot be moved.
NOTE:
If the header is not on the down stops during this
procedure, the voltage may go out of range during
operation, causing the AHHC system to malfunction.
