4.5.1 SEED DISTRIBUTOR

A disk (2, fi g. 14), chosen according to the size of the seed, is
assembled inside the distributors (1, fi g. 14) (the seed should not
enter the hole). Should suction cause some seeds to clog the
holes of the disk, these will be left on the ground. The seeder is
delivered to the customer with a single set of discs is equipment.
The Manufacturer can supply the client with the following sets of
disks (pag. 61).

out by expert personnel, equipped with protective gloves, in
a clean and dust-free environment.

and in a stable position.
- Only clean parts that are in good condition must be assembled.
- The disk must be assembled with the pegs (2, 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.
