Spreading disc, lateral distribution, throwing vanes
The spreading disc must rotate counterclockwise. With the throwing vanes attached to
the spreading disc, the spreading pattern can be adapted to the specific weight
(density) of the spreading material. This results in uniform lateral distribution. The
spreading plate has 2 throwing vanes that are positioned not quite parallel to each
other.
Proceed as follows:
1) Depending on the desired spread rate and the working width, take the required
settings (spreading plate speed and slider opening) from the setting charts.
2) Adjust the setting of the throwing vanes on the spreading plate to achieve optimal
lateral distribution for the selected working width.
When doing so, be sure to disconnect the power supply from the control box.
To adjust the throwing vanes, loosen them and turn the throwing vane to the
required position.
Then re-tighten all of the bolts.
There are marks directly on the spreading plate, which can be used to see the current
position of the throwing vanes:
Throwing vane I at Point 4
Throwing vane II at Point 4

To obtain optimal lateral distribution with slug pellets, the setting of the throwing vanes
must be adjusted for the desired working width. The numbers listed in the table serve
as reference values. The lateral distribution must still be checked on the field.
The following general rule applies
for all seed types
: If the spreading density is higher
in the outer area than in the middle, the throwing vanes must be adjusted further
towards "Point 1".
NOTE:
The slider is only opened when the spreading plate is rotating!
