DISTRIBUTION ADJUSTMENT
Distribution adjustment must be done in compliance with:
- the kind of seed that has to be distributed;
- the longitudinal distance between one seed and another.
Kind of seed to be distributed:
Identify the diameter of the holes of the seed disk in Table 3, ac-
cording to the type of seed to distribute.

The values shown on the table are approximate. The defi nite
choice of seed plates is completely up to the user. Complaints
for imprecise sowing due to utilization of improper seed plates
will not be accepted.
Longitudinal distance between one seed and another:
The longitudinal seeding distance is determined by the number
of holes on the seed plate, by the number of teeth and position of
the gears on the wheel which transmits the motion to the gearbox,
and by how the gears are combined in the gearbox. On the cover
of the gearbox there is a table for adjusting the seeding distance
and a table that shows the drive fi tted on the gear drive wheel.
1) From the Seed Investment Table:
Depending on both the row distance of the planter and the selected
seed investment per hectare, calculate the longitudinal seed plan-
ting distance by using Table 2 (Seed Investment Table).
Example:
- Seeding row distance 75 cm;
- number of seeds to be distributed per hectare: 72.000.
According to the "Seed investment Table", the longitudinal distance
between one seed and another is 18,50 cm.
For row distances differing from those listed in the table, apply the
following directions:
Longitudinal seeding distance =
Example:
- Ha = 10000 m 2 ;
- Row distance = 0,90 m;
- No. of seeds to be distributed for hectare = 70.000

USE AND MAINTENANCE
2) About the Seed Planter:
Verifi y which couple of pinions (Wheel) is to be found (C-D ill. no.
35) in the seed planter;
3) From the Table of Longitudinal Seed Planting Distances
(Table 4):
- Look for the table that lists the couple of pinions equal to the
seed planter's one;
- Seek the value of the longitudinal seed planting distance pre-
Table 3 viously calculated. Should there be two or more types of disks
that assure the same longitudinal seed planting distance,
prefer the disk with the largest number of holes.
- Move left and see on which pair of gears (A-B, Fig. 36) to place
the gear chain;
4) About the Seed Planter:
- Set the gearbox with the identifi ed ratio (A-B);
- If using the pinions (C-D) mounted on the seed drill (Fig. 36) you
do not achieve the desired sowing distance, use the alternative
chart paying attention to set the correct transmission ratio (C-D=
Z10-Z23... or Z16-Z23).
To change the transmission ratio, remove the protective
guards and loosen the chain tensioner (2, Fig. 36); swap
the position of the gears (C) and readjust the chain (20).
Stretch the chain again with the tensioner (19) and put the
transmission protective guards back on.
- The gearbox transmission must be checked every time the
longitudinal seed planting distance is changed (see following
section).
