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 3 different functions and accessories to cater for
border spreading.
•
one-sided boundary spreading with the border spreading plate,
•
boundary track spreading with the border-spreading cylinder,
•
Border spreading with the border-spreading pipe.
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.
Environmental standards
The maximum acceptable loss over the parcel border is determined by
environment standards (EN 13739-1). In order to comply with the
standard the quantity of fertiliser spread beyond the parcel border
must be a maximum of 10% of the quantity distributed in the centre
behind the spreader (= 100%). Test if the border spreading plate
(optional extra) door de test therefore always before hand as
described in
 paragraph »Testing the border spreading pattern« on page 100.
One-sided boundary
spreading with the
border spreading plate
Operation
Drive with one-sided boundary spreading at approx. 10 feet from the
field edge. With the aid of the border-spreading plate you complete the
first full-field spreading pattern that is spread on 40 feet (also the
headland sprayer tramline).
Choice for environment or yield with border spreading
Depending on the set application rate,
•
30% of the full-field application rate (environment setting) or
•
50% of the full-field application rate (yield setting),
you will spread almost nothing or the maximum permissible number of
granules over the field boundary.
 see also paragraph »Testing the border spreading pattern« on
page 100.
Setting options
Set the boundary at the field edge by:
•
Placing the border-spreading plate in working position,
•
reducing the PTO shaft rpm to 370 rpm,
•
reducing the application rate to 30% - or 50% of the full-field
application rate
•
and, where necessary, changing the turn angle of the spreading
spout.
