3.6 SEED SELECTION

3.6.1 SEED DISTRIBUTOR

A plate (1, Fig. 16), chosen according to the size of the seed, is
installed inside the distributors (Fig. 16) (the seed should not be
able to enter the hole). Should suction cause some seeds to clog
the holes of the plate, these will be left on the ground. The seeder
is delivered to the customer with a single set of plates already
installed on the distributors. The Manufacturer can supply the client
with further sets of plates. (see table 3, page 57).
REPLACEMENT OF SEED DISC AND ADJUSTMENTS
All operations described in this paragraph must be carried
out by expert personnel, equipped with protective gloves, in
a clean and dust-free environment.
- The seeder must be clean and dry and stably positioned.
- If the power take-off is hooked to the tractor it must
disconnected, the engine turned off, the key removed and
the hand brake pulled.
- Only clean parts in good condition must be installed.
- The plate must be assembled with the pegs (2, Fig. 16) poin-
ting towards the inside of the distributor.
- If some of the pegs are bent or missing from the plate, this
means that foreign bodies have entered the distributor, in
which case the plate must be replaced.
- If there are circular scratches, they must not exceed 1/3 of
the plate thickness.
- Hand-tighten only the winged nut that closes the cover (Fig.
17).
N.B. When replacing worn plates, the cover gasket should
also be replaced.
These are the operations to be carried out:
1) Unscrew and remove the wing nut (Fig. 17);
2) Open the distributor cover;
3) Insert or replace the disc;
4) If necessary, adjust the seed-spill prevention plate as described
further on;
5) Adjust the selector, as described further on;
6) Close the cover and screw the wing nut back on (Fig. 17).
7) Adjust the selector as described further on

REPLACING THE COVER SEAL

Check the whole of the seed distributor cover seal surface
regularly (A Fig. 18) for signs of wear.
The seal must be replaced before the surface «A» (Fig. 18), being
worn down by the disc movement, reaches surface «B». Also check
that no grooves have been made by the disk along surface «A».

EXPELLER SEEDS

The seed expeller is to be used only with sugar beet seed.
Remove the expeller with large seed such as corn, sunfl ower,
soybean, peanut, etc.
Loosen the screws (1, Fig. 19) and remove the expeller (2).
Assembly
Position the expeller (2) as shown in Figure 19.
keeping the expeller pressed against the edge, obtained in the
relative seat (3, Fig. 19), block it by the screw (1) kit. The screw is
to be mounted only as shown in the picture. Do not interpose any
thikness between the expeller and its seat.
Make sure the expeller is fl at against the seed disk but that it does
not come in contact with the disk. Replace the expeller when
worn.
