Spray Boom
Boom Movements When Spraying
The operator of the sprayer must consider the field conditions before spraying, as this could include a change to the boom
setup regarding suspension and damping.
The object is to have the unfolded boom aligned parallel to the ground when driving in the field, as this will optimize the
spraying.
At delivery, the spray boom is normally set in a neutral position (2), meaning that the unfolded boom will follow the
movements of the sprayer’s wheel axle to some extent = an active boom. This works for many field conditions.
The trapeze in the boom center can be adjusted, if you need another setup.
This is relevant for sloping fields and for uneven or bumpy driving tracks.
Mechanical Adjustment of Guide Rods
The guide rods (A and B) can be moved to another position to make the boom follow the wheel axle movements even more
when driving in the field.
The guide rods are either parallel to each other (1) or angled (2):
1.
Parallel: Neutral boom damping - active boom which only partly
follows the wheel axle movements.
2.
Angled: Hard boom damping - passive boom which mainly
follows the wheel axle movements.
Adjustment of the guide rods requires two persons, as the boom center structure needs to be handled to make the guide
rods fit into the other hole positions.
The photo shows neutral position of the two guide rods (A and B) located at the top of the boom center.
