4.6.7 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.
- Add a small seed quantity (approx. 40 kg) inside the hopper.
- Loosen the knobs (A, Fig. 34) and remove the sliding gates
(B).
- Position the seed collecting trays under the seed discharge
outlets (C Fig. 34).
- Calculate the gate opening value, with the help of the Table 2-3,
on the basis of the type of seed to be used and the quantity to
be distributed.
WARNING: Make sure the correct seeding roller is being
used.
- The seed table is also af fi xed to the machine and from this table
it is always possible to calculate approximate seed distribution
quantities.
It is, however, always necessary to carry out a sowing
test!
- Loosen the fastening screw on the gear adjuster (Fig. 35)...
- ... and bring the graded indicator to the required position (de-
pending on the quantity of product to be distributed), by rotating
the adjuster knob (Fig. 36).
- Once the sowing test has been successfully performed, secure
the fastening screw of the gear adjuster once more (Fig. 37).
WARNING: Do not use tools to tighten the knob. Do not
tighten too much. A slight “clamping effect” of the brake is
suf
fi cient.
In order to perform the actual sowing test itself, insert the sowing
test handle in the gearbox and rotate as shown (Fig. 38).
The revolutions of the handle correspond to a 1/40 of a hec-
tare.
Next check, using precision scales, the quantity of product collected
and multiply this by ten in order to obtain the quantity distributed (in
kg./ha). Make any necessary adjustments. Start up the machine,
performing the above mentioned steps in reverse order.
