11.3 Folding boom
11.3.1 Folding boom control
WARNING
Danger cause by unexpected movements in
automatic mode. Never come close to the
ultrasonic sensor, while the BoomControl
is in automatic mode.
Proper condition of spraying boom and
suspension have a considerable influence
on the distributing accuracy for the spray-
ing mixture.
Complete overlap is achieved by correctly
adjusting the spraying height of the folding
boom to the crop.
An automatic height and inclination control
adapts the folding boom to the crop.
Ultrasonic sensor on the folding boom
11.3.2 BoomControl
Further development of the automatic folding
boom guidance to maintain the exact, lowest
possible working height, even when driving with
high travel speed and in highly cropped terrain.
This creates the prerequisite for minimum drift.
Active adaptation of the folding boom via middle
section height guidance; independent bending
of both boom arms (controlled by 4 sensors,
distributed over the entire boom);
NOTE
When the spray 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 adjusted height.
