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. 41) 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. 41) 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. 41) 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. 41). 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.
41) preventing their rotation and consequently distribution.
Perform the dosing test following the instructions supplied in paragraph 3.3.2 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.
