5.4 SEED SELECTION

5.4.1 SEED DISTRIBUTOR

A plate (1, Fig. 28), chosen according to the size of the seed, is
installed inside the distributors (Fig. 28) (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 64).
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 be di-
sconnected, 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. 28) 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. 29).
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. 29);
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. 29).
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. 30) for signs of wear.
The seal must be replaced before the surface «A» (Fig. 30), 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 DEEDS
Use the light grey coloured seed expeller (C, Fig. 31) for small size
seeds with an average diameter less than 3.5 mm (e.g. pelleted
sugar beet seed). Use the black coloured seed expeller (D, Fig.
31) for medium size seeds with an average diameter from 3.5 to
7 mm (e.g. corn).
Remove the seed expellers when using seed with an average
diameter greater than 7 mm.
Loosen the screws (1, Fig. 31) and remove the expeller (2).
Assembly: Position the expeller (2) as shown in Figure 31.
keeping the expeller pressed against the edge, obtained in the
relative seat ( 3, Fig. 31), 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.
