The standard Factory Setting (FS) fin position
is:-
Medium Fin position C
Long Fin position 1
Figure 25 shows the fins on the left hand
spinner in this position. If in doubt at where the
best fin setting position is for a particular
pelletised product, set them to the Factory
Position (FS).
Warning! The tractor must be turned off
before working on the spinners. Spinners
could turn at any time
.

The Ctr Vee Back Board can remain in
its Factory Setting of 130mm in most situations.
Adjustment forward may be necessary for
extremely light rates or to narrow the spread
width.
The Back Board Extension panel on the Ctr
Vee should be fully extended to minimise the
gap between the Side Panels and the Back
Board. Excessive gap may compromise
accuracy of spread pattern.
The
Front Discharge Slide will be set to 0mm
in most situations. The only reason to alter this
would be if the spinner fins hit the slide and it is
needed to be raised slightly to clear.
The
Side Panel will normally be set level with
the bottom of the Front Discharge Slide. Again
the only reason to raise this if a fin is too close
to the panel.
