3.5.2 DISTRIBUTION OF FINE SEEDS
Distribution of quantities lower than 3 kg/ha.
During the dosing test the number of gearbox revolutions is low
because the quantity of product to be distributed is small. This
can result in irregular distribution of the product. If the operator
notes this, he should follow the instructions below.
Considering that every section (A, Fig. 26) of the dosing roller
distributes 20% of the product contained in roller itself, the number
of operating sections can be increase and the gearbox rotation
speed to reduce to obtain more homogeneous distribution.
First, take the dosing roller off the machine. Then, unscrew the
knob (B, Fig. 26) using the supplied wrench and remove the lock
nut (C). Extract the section(s) to be activated and put them back in
their positions (1-2-3-4-5, Fig. 26) turning them by 180°.
When re-assembling the sections, make sure that during
operation the dosing grooves of the active sections are staggered
from one another (D, Fig. 26). This will give continuity to
distribution.
Re-position the lock nut, tighten the knob using the supplied
wrench and assemble the roller back on the machine.
Block the cleaning element in the operating position and make
sure that the springs hook the previously excluded sections (E,
Fig. 26) preventing their rotation and consequently distribution.
Perform the dosing test following the instructions supplied in
paragraph 3.5.4 and make sure that the real number of operating
sections is coherent with the 1 section roller.
IMPORTANT!
The quantity values in the table refer to a dosing roller where 1,
3 and 5 sections are actually operating (1/5 - 3/5 - 5/5).

When the same quantity is to be distributed, to reduce
the opening of the gearbox of every activated section
by 20%.
To start distribution again using some of the sections or all of
them disassemble the roller and its parts and put them back in
their original position.
3.5.3 OVERFLOW BULKHEAD ADJUSTMENT
An important arrangement for optimised seed distribution is the
adjustment of the rubber overflow bulkhead inside the metering
unit (Fig. 27).
