Activities before spreading

Working width
The working width must be selected to set the spreader. This could for
instance be the distance between the sprayer tramlines.
Turn to the page in the spreading chart book that contains details
about the selected working width for the fertiliser type with the most
comparable features.

NDICATION
Various types of fertiliser have a limited maximum working width. This
is due to their physical qualities whereby they do not spread evenly
over large working widths. If a working width is not given in the
spreading chart the relevant type of fertiliser cannot be spread evenly
over that width.
I
NDICATION
If you want to spread with a working width not given in the spreading
chart book, use the settings for the working width closest to the
selected working width. For example: the settings given in the
spreading chart for a required working width of 25 metres could, for
instance, be approximated to 24 metres. Enter the actual working
width into the control system so that the selected application rate is
correctly distributed.
The working width is adjusted with:
•
the vanes in combination with the PTO shaft revolutions (RPM)
and
•
the discharge point.
Vane combination
The working width of the spreader is determined by the length of the
vanes. The machine provided has 4 pairs of vanes, with lengths of 135
mm, 185 mm, 235 mm and, as an optional extra, 285 mm. The
spreading chart or the online spreading chart indicates which vanes
should be used, depending on the desired working width.
The order of assembly is shown in the following illustration.
See also section »Vanes« on page 48.
Indication
The working width (X) is also a measure for the distance the spreader
has to spread to the left, to the right and to the rear.
See also section »Working method on the headland« on page 161.
Indication
If the (online) spreading chart describes another vane combination or
another PTO shaft rpm, use the values from the (online) spreading
chart.
