3.5 REPLACING THE SEEDING DISK AND ADJUSTMENTS
CAUTION
All the 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, detached from the tractor
and in a stable position.
- Only clean parts that are in good condition must be
assembled.
- The disk must be assembled with the pegs (1 Fig.14)
pointing towards the inside of the distributor.
- If some pegs are bent or missing from the disk it means
that foreign bodies have entered the distributor and so the
disk must be replaced.
- If there are circular scratches, they must not be more than
1/3 of the disk thickness.
- Hand-tighten only the winged nut that closes the cover (A
fig. 13).
N.B. When the worn discs are replaced, the cover gaskets
should also be replaced.
These are the operations to carry out:
1) Lift the single seeder from the ground in the following way:
- Hook the spring the position 1 (Fig.15)
- Lift the seeder until it hooks,
- Hook the spring the position 2 (Fig.15);
2) If fitted, remove the antibounce bolt (1 Fig.16);
3) Unhook the lister (2 Fig.16) by removing the spring (3);
4) Unscrew and remove the winged nut (A Fig.13);
5) Open the distributor cover;
6) Insert or replace the disc;
7) If necessary, adjust the seed-spill prevention plate as
described further on;
8) Close the cover, insert the spring washer and tighten with
the wing nut, hook up the planter shoe again, put back the
antibounce screw (if fitted);
9) Adjust the selector, as shown further on;
10) Lower the seeder in the opposite direction described at point
1.
3.5.1 REPLACING THE COVER SEAL
Check the whole of the seed distributor cover seal surface
regularly (A Fig. 17) for signs of wear.
The seal must be replaced before the surface «A» (Fig. 17),
being worn down by the disc movement, reaches surface «B».
Also check that no grooves have been made by the disk along
surface «A».
