Dosing Test - Gaspardo ALITALIA Emploi Et Entretien

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. 49) of the dosing roller di-
stributes 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. 49) 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. 49) 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. 49). 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. 49)
preventing their rotation and consequently distribution.
Perform the dosing test following the instructions supplied in
paragraph 4.4.1 and make sure that the real number of operating
sections is coherent with the 1 section roller.
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.

4.4.1 DOSING TEST

Adjust the doser with the unit on the ground, the motor turned
off and the tractor blocked in place. Before carrying out the
dosing test, make sure there are no foreign bodies inside the
hopper and the doser.
1) Add a small seed quantity (approx. 40 kg) inside the hopper.
2) Remove the bend under the injecting tube (A, Fig. 50), by
loosening the quick closing device.
3) Position collecting container (C Fig. 50).
4) Carrying out the dosing test: to rotate the dosing devices,
follow the instructions provided in the Operation and Mainte-
nance Manual of the Electrical Distribution Control.
WARNING: Make sure the correct seeding roller is being used.
