Use in the field

Over and underdosing
Depending on soil or crop composition, it is preferable to spread more
or less fertiliser locally. This could for instance be where experience
has shown that certain parts of the field need more or less fertiliser
than others.
It is possible to over or underdose by
•
driving faster whereby the spreading quantity per hectare is
reduced,
•
drive slower, which will increase the spreading volume per hectare,

NDICATION
The rpm of the tractor engine (therefore also of the PTO shaft) must
remain constant (concerning distributing fertiliser along the width).
The driving speed can only be adjusted by selecting another
speed!
Results of one-sided over- or
underdosing
The spreading pattern of both spreading discs overlap partially,
especially in the middle behind the spreader. The effect of over or
underdosing would be greatest in the middle and rear of the spreader.
You will see the effect especially with narrow working widths because
that is when the spreading patterns overlap the most.
With small working widths in which you spread in a triangular
spreading pattern, the first and second passes of the spreading
patterns overlap each other completely.

To distribute an adjusted application rate you must therefore over- or
underdose on the first as well as the second pass in the following
tramline.
