Border spreading
Spreading fertiliser up to the border of the property requires
concentration. On the one hand you want to achieve maximum cover to
the field edge to ensure a good crop, while on the other hand you want
to minimise the loss over the field edge.
The spreader has 2 different functions and accessories to cater for
border spreading.
•
one-sided boundary spreading with the border spreading plate,
•
boundary track spreading with the tramline cylinder.
When one-sided boundary spreading, drive with the tractor along the
field edge and spread from the border inwards. With boundary track
spreading, drive down the first sprayer tramline from the field edge and
spray in the direction of the border.
One-sided boundary
spreading with the
border spreading plate
Operation
Drive along the field edge when one-sided boundary spreading and
send the flow of fertiliser granules with a border spreading plate
(optional extra). The working width on the side of the field edge can be
adjusted by changing the border spreading plate (optional extra).
Application rate correction with
border spreading
It should be possible to adjust the set application rate while busy with
border spreading using the border spreading plate, depending on the
method of fertilization:
Situation A meadow fertilizing with full adjoining working width:
Adjust the application rate as per the chart given here.

See also paragraph »Application rate« on page 63.
Situation B Fertilizing along tramlines:
Application rate as set for full field spreading.

(environmental
approach)
Spread less to the field edge. This will decrease
the loss over the field edge, but the cover will
not be as good
Direction
Y
(profit approach)
Spread more to the field edge. Cover is better,
but the loss is greater

Select higher acceleration with 450 rpm in order to maintain the driving speed or adjust the application rate (-15%) when deceler-
ating.
It is therefore not necessary to adjust the application rate when decelerating (+15% -15%=0).
