Then test the connecting full-field spreading pattern with the right
PTO shaft rpm.
Divide the troughs as described below; with a fictitious ditch.
Review and adaptation
The maximum acceptable loss in the ditch is determined by
environment standards (EN 13739-1). In order to comply with the
standards, the quantity of fertiliser in the trough, standing in the
fictitious ditch, must be a maximum of 10% of the quantity collected in
the trough in the middle of the track (= 100%).
Adjust the PTO shaft rpm at the first full-field round if more than
10% is spread into the ditch.
I
NDICATION
Bring the PTO shaft rpm for the successive rounds back to the
correct value.
Connecting spreading pattern
with border-spreading cylinder
Perform the first round with the border-spreading cylinder at half
working width from the field boundary or ditch.
Check if the furthest fertiliser granules get spread up to the tractor
tracks of the next full pass.
Place the troughs lengthwise onto the driven tractor track on the
side of the next round.
Spread the first full-field round and check a few granules lying in
the troughs.
Possibly adjust the rpm slightly.
Keep the driving speed constant at the value with which you
calculated the application rate!
I
NDICATION
If you are using the ED II the dosing will automatically be adjusted to
the new driving speed.
