4.3.2 Adjust the Sensor Offset
To compensate for the lack of crop in the “wheel track”, adjust the main lift
sensor’s height reading offset (Zero Height) so that the sensor will read
higher to match the average height of your crop. Carry out the following
procedure using the UC4 control panel:
1. Make sure you are in manual mode, at the operating screen.

2. Navigate to the "More ?" item in the SENSOR DISPLAY menu. Press
AUTO (YES).
3. Navigate to the "Main ?" item in the SENSOR DISPLAY menu. Press
AUTO (YES).
4. Toggle SENSOR DISPLAY to display the MLht menu item.

5. The “+” switch will increase the reading, the “–“ switch will decrease the
reading. DECREASE the reading by the difference in height between
standing crop and trampled crop in the “wheel track”. Adjust this until
ALL three sections (right, left, main) are level in the field while in
AUTOMATIC mode. This may take some experimentation in field
conditions.
6. To return to the operating screen, press and hold SETUP for two seconds.
Note that this is subject to a “trial and error” approach to getting this set
adequately. The advantage is that AUTOMATIC control will be retained for
the center section. Depending on the crop, the depression caused by the
wheel might vary. Note that when turning the implement, the “wheel track”
will follow a different path. If the roll sensor detects standing crop in this
situation, the center section will lift momentarily.
NOTE: zero height (for the main lift sensor) will need to be reset when using
SOIL MODE operation.
4.3.3 Add an Additional Sensor
The final option would be to add a fourth sensor to your system to handle the
main lift measuring duties. This sensor would need to be mounted on the
center section such that it will NOT read in the wheel track. If you use this
option, ensure that the roll sensor and the added sensor are located at least 36
