NOTE:
If an error code appears during calibration, the height
sensor output is out of the specified voltage range, and so
the height sensors must be adjusted. For instructions, refer

(John Deere 60 Series), page 176.
4.11.3 Turning Off Accumulator (John Deere 60 Series)
Activating the accumulator on a John Deere 60 series combine will negatively affect the speed at which the AHHC system
adjusts the height of the header. Turning the accumulator off will ensure good AHHC performance.
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 updated information.
