Increasing the travel speed while leaving both
nozzle size and spraying pressure unchanged,
reduces the placing quantity.
Reducing the travel speed while leaving both
nozzle size and spraying pressure unchanged,
increases the placing quantity.
The travel speed is freely selectable, based on
the automatic, area related spraying quantity
control via the spraying computer.
The agitator normally remains switched on from
filling to the end of spraying. The information
provided by the preparation manufacturer are
decisive in this respect.
Example
Required application quantity: 200 l/ha
Intended
Travel speed: 8 km/h
Nozzle type: AI / ID
Nozzle size: 03
Permissible pressure range for
the installed spraying nozzles:
3 bar (min.) -
8 bar (max.)
Intended spraying pressure: 3.7 bar
Permissible spraying pressures: 3.7 bar ±25%
2.8 bar (min.) -
4.6 bar (max.)
11.4.3 Adjusting the spraying
height
WARNING
Danger of crushing and impact for persons
when lifting or lowering for height adjust-
ment of the spraying boom!
Expel persons from the danger zone of the
machine, before lift or lower the spraying boom
with the height adjustment.
NOTE
Adjust the spraying height (distance be-
tween nozzles and crop) as per currently
applicable guidelines.
Always adjust the spraying boom parallel to
the ground, because the specified spraying
height can only be achieved in this condition.
Carry out all adjustment work on the spray-
ing boom conscientiously.
11.4.4 Spraying pressure, nozzle
size, placing quantity, travel
speed, agitator
Should the spraying pressure drop considerably
all of a sudden, the spraying mixture container
is empty.
Should the spraying pressure drop under oth-
erwise unchanged conditions, the suction or
pressure filters are blocked.
Spraying pressure and nozzle size have an
influence on the drop size and the sprayed out
fluid volume.
The higher the spraying pressure, the smaller
the drop diameter of the sprayed spraying mix-
ture. The smaller droplets are subject to higher,
undesired windward drift!
Increasing the spraying pressure also increases
the placing quantity - reducing the spraying pres-
sure will also reduce the application quantity.
