3.4 PREPARATIONS FOR SEED DISTRIBUTION

To obtain the correct rate of seed distribution per hectare (Kg/Ha)
the distributing parts must be suitably adjusted: the gearbox, the
feeler pins and the rollers.
A rough guide can be obtained from the seed planting table (see
sowing test chapter 3.4.8). The values that you will need for this
are: planting unit model, number of rows, type of seed (wheat,
barley, etc.) and the quantity in kg to be distributed per hectare.
3.4.1 GEARBOX (SEED)
The gearbox is positioned on the right side of the machine and
its motion is given by the driving wheels. The speed of the seed
distributing units can be changed from the gearbox by moving the
adjustment lever that is calibrated continuously on a scale from 0
to 55 (Fig. 11).
To set or change the gearbox pointer, loosen the knob, put the lever
at the bottom of the scale «55», then put it on «0» (zero) and then po-
sition it on the value found. Lock it in position by tightening the knob.
3.4.2 ADJUSTMENT OF THE BOTTON PLATE
The botton plate adjustment lever (Fig. 12) is positioned on the right
side of the machine and works on a scale that is graduated from
1 to 7 positions. This lever must be positioned according to the
number given in the seed planting table for the type of seed used.
Position the lever of the botton plate (to the right of the hopper) on
the 7-position pointer (Fig. 12):
N° 1, for small seeds (rape, etc);
N° 3, for medium seeds (wheat, barley, etc.);
N° 7, for large seeds (peas, soybean, etc.).
When the botton plate (B, Fig. 13) are correctly positioned they
ensure smooth and steady distribution of the seeds.
ATTENTION
If the lever is positioned beyond the maximum opening (>7),
the seeds will be discharge from the hopper.
To obtain optimum seed distribution check the adjustment of the
botton plate at regular intervals (B):
1) position the lever (Fig. 12) on reference «0»;
2) the lever (Fig. 14) in position «A»;
3) using screw (D), adjust the distance between the feeler pin and
the distributing roller to between 0.5 and 1 mm (E, Fig. 13).

3.4.3 ADJUSTMENT OF DOSING ROLLERS

Before beginning seed planting, choose the most suitable distri-
buting roller (Fig. 14) for the type of seed.
ATTENTION
The dosing rollers must always be selected with the hopper
and the distribution boxes empty (Fig. 14).
The machine can be used with rollers for the distribution of small,
medium and large seeds. Select the type of distributing roller to
use according to the information given in ADJUSTMENT TABLE
OF THE SEEDER (page 49). Selection of the roller for small seeds
is made by moving the lever to position (G, Fig. 14). In position (F,
Fig. 14) the roller is selected for medium/large seeds.
3.4.4 ADJUSTMENT OF SEED GATES
The seed gates for (C, Fig. 13) closing off the seed fl ow from the
hopper have two positions:
1) closed gate: seed fl ow completely closed and therefore the
seeds do not reach the distributing roller.
2) open gate: seed fl ow completely open.
