Activities before spreading

Application rate
The control system can drive the spreader in three different ways:
•
distribution that resembles the settings for the preset application
rate must be determined under changing circumstances through
automatic calibration and driving speed correction,

see the section below,»Constant application rate«.
with similar or lower application rates (< 40 kg/min) the fine
application kit should be used,

See section »Discharge point« on page 110.
•
with very low application rates on very uneven terrain preset
application rates must be checked manually to ensure that the
correct dosing setting is being distributed, without automatic
calibration, but with driving speed correction,

See section »Manually entered application rate« on page 119.
•
under changing circumstances location specific application rate
driven by an external signal, through automatic calibration and
driving speed correction,

See section »Variable, externally driven application rate« on
page 126.
Constant application
rate
The control system can spread an equal amount of fertiliser over the
entire site. The control system thereby corrects the control system for
changes in driving speed, while maintaining the option to adjust the
application rate manually for over or under dosing.
The control system can search for the correct dosing setting with the
preset application rate through automatic calibration. The
disadvantage is that the application rate for the second automatic
calibration (= approx. 2 minutes) could differ markedly from the
selected application rate. It is therefore strongly recommended that
the starting values be taken from the spreading chart book. This can
be done in the ‘Curve Calibration’ screen. The control system
calculates the discharge curve from the starting values. The control
system corrects the spreader for changing circumstances, based on
this curve, e.g. as a result of changes in driving speed.

See also section »The ISO control system« on page 30.
Look for the most comparable fertiliser type and the correct settings
for the selected working width in the spreading chart.

Read the setting of the dosing in the Dosing Setting column that
goes with the selected application rate and driving speed.

The corresponding flow rate is given in the Kg/min column.

The given values are to be entered in the control system.
If the selected application rate is not given in the spreading chart book,
use the settings that are the closest to the selected application rate.
If the selected driving speed is not given, use the settings closest to
the selected driving speed.
