Metering automatics:
Within one tractor gear the forward speed related metering is
achieved. That means, if the tractor engine rev. speed drops, e.g.
due to a gradient, in addition to the forward speed also the trac-
tor universal joint shaft rev. speed and thus the pump drive re.
Speed drops in the same ratio. Hereby also the pump capacity
changes in the same ratio and the desired spread rate [l/ha] is
maintained – within one tractor gear. At the same time also the
adjusted spray pressure changes.
WARNING
To achieve the optimum effect of the spray cocktail to be spread
and to avoid unnecessary environmental harm the spray pres-
sure for the relevant nozzle has to be maintained within the rele-
vant pressure range (see spray rate table).
Example:
When the adjusted spray pressure is,
for example, 3,2 bar
, spray
pressures of between
2,4
and
4,0
bar are allowed. Never ever leave
the permissible pressure range of the installed nozzles.
When increasing the forward speed do not exceed the maximum
permissible pump drive rev. speed of 550
R.P.M.!
WARNING
Bigger deviations of the spray pressure would cause an unde-
sired change of droplet size of the spray cocktail!
Switch on and off the sprayer boom only whilst driving.
•
During spraying operation accurately maintain the pre-selected
tractor gear and the agitation intensity, as otherwise deviations
from the desired spray rate would result.
•
During the spraying operation continuously check the spray
cocktail consumption in relation to the treated area.
•
In case of a considerable drop of the spray pressure the tank is
empty. If in case of unchanged conditions the spray pressure
drops, either the suction or the pressure filter is blocked.
•
All spray rates l/ha in the spray rate table are valid for water.
Multiply the corresponding values for AUS by 0.88 and for NP
solutions by 0.85.
