3.3.2 DISTRIBUTOR ADJUSTMENT AND TEST
DISTRIBUTOR ADJUSTMENT
The information for correct seed distribution can be obtained
from the table code 19702771. The information to bear in mind
is: the specific weight of the fertiliser and the quantity in kilograms
per hectare.
Size and type of fertiliser: adjust the distributor according to the
selected seed (see table 19660060).
The quantity of seed per hectare is adjusted by the metering
device (Fig. 15) by varying the opening of the sliding gate (F)
by means of the threaded rod (D), to the corresponding value
in the left-hand column of the fertilizer distribution table.
DISTRIBUTOR TEST
Once the distributor has been adjusted, a test has to be carried
out to check the correct seed distribution, as the table values
are purely reference values, owing to the diversity often found
in size and specific weight of the seeds.
Shut the slide valve sompletely with the seedhopper empty.
Put a small quantity of the product (about 40 kgs) into the
hopper. Adjust the slide opening of the distributor to a slightly
smaller value than the one indicated in the table.
ATTENTION
Do not close the gate when there are seeds inside the
doser: this would result in the dosing parts being broken.
Remove the curve positioned under the injector channel and
place a bowl underneath. With the gear ratio N make 80 turns
of the handwheel (equal to 1/10 hectare) and multiply the result
by 10. Of the value obtained is less or greater than that required,
open or close the gate by a few units and repeat the test.

During dosage trials with planting units with double
metering devices, ascertain that each one delivers the
desired quantity of seed, in keeping with the distribution
table.
Do not close the gate when there are seeds inside the
doser: this would result in the dosing parts being broken.
Once the test has been finished, fasten the curve again to the
injecting tube. By doing so, make sure that the curve flange is
in a balanced position with regard to the tube.
REGULATION CHART
Example:
Requested fertilizer quantity: 200 kg/ha
- a value between 50 and 55 is obtained from the table. As
previously described it is advisable to set the distributor
opening at a lower value, in this case value 50 will be set
- 21 kg are obtained from the rotation test
- this amounts to approx. 5% less than the requested value
- also increase the adjusting value by 5%, thus reaching 52÷53.
- 20 kg are obtained from the second rotation test.
The chart values are only approximate, since the specific weight
and the size of the granules often differ. It is, therefore
recommended that a rotation test be performed. The amount
measured with that test is then constantly output.
ATTENTION
During dosage trials with planting units with double
metering devices, ascertain that each one delivers the
desired quantity of seed, in keeping with the distribution
table.
