BoomControl
WARNING
Danger caused by unexpected movements
in automatic mode. Never come close to the
ultrasonic sensor, while the BoomControl is
in automatic mode!
When operating the sprayer under high volt -
age power lines disable the BoomControl
and operate the slope compensation manu -
ally!
No persons may be present under the folding
boom and in the danger zone!
The BoomControl function must be disabled
when leaving the tractor cab!
The BoomControl folding boom control is used
for the automatic distance control of the spray-
ing boom.
Ultrasonic sensors measure the distance to
the ground or the crop and the folding boom is
then adjusted in accordance with the nominal
distance values. An automatic height and in-
clination control thus adapts the folding boom
distance to the crop. The crop should be closed
and not show any gaps. Correct functioning re-
quires sufficient hydraulic and pneumatic power
of the tractor.
The scanning width of a sensor is approx. 0.5 m.
If a gap in crop or a trench wider than 0.5 m is
detected under the sensor, the corresponding
boom segment will be lowered (danger of dam-
ages).
When passing over very smooth surfaces, such
as e.g. water puddles, the ultrasonic signal may
be reflected. The control must in these areas be
deactivated.
¾
BoomControl does not relieve the driver from
his responsibility to constantly check the
position of the folding boom and to interfere
manually, if needed!
NOTE
When the spraying boom is switched off at the
headland, the spraying boom is automatically
raised by a previously defined value.
When switched back on, the spraying boom will
return to its set height.

Automatic folding boom control with active ad-
justment by the sensors on the two outer wings.
This ensures minimum drift at the lowest pos-
sible working height, even at high speeds, on
flat or slightly hilly terrain.
