3.2 ADAPTING THE CARDAN SHAFT

The Cardan shaft, supplied with the machine, is of standard
length.
Therefore it might be necessary to adapt the Cardan shaft. In
that case, before doing anything, consult the Manufacturer for the
eventual adaptation.
- When the Cardan shaft is pulled out as much as it can go, the
two pipes must be superimposed for at least 15 cm (A fig.
11). When it is inserted all the way , the minimum play allowed
must be 4 cm (B fig. 11).
- When using the equipment on another tractor, check what
has been set out in the previous paragraph and check that
the protections completely cover the rotating parts of the
Cardan shaft.
As far as the transport of the seeder is concerned, always
follow the Manufacturer's instructions.

3.3 STABILITY OF PLANTING UNIT AND TRACTOR

DURING TRANSPORT

When a planting unit is coupled to a tractor, so becoming an
integral part of it for the purposes of road travel, the stability of the
planting unit-tractor complex may change and cause driving or
operating difficulties (rearing up or side-slipping of the tractor).
The condition of equilibrium can be restored by placing a sufficient
number of ballasts on the front of the tractor so that the weights
on the two tractor axles are distributed sufficiently evenly.
To work in safety the instructions given in the highway code should
be followed; these prescribe that at least 20% of the weight of the
tractor alone should be borne by the front axle and that the weight
on the arms of the hoist should not be more than 30% of the
weight of the tractor itself. These factors are summarized in the
following formulas:
M x s < 0.2 x T x i + Z x (d+i)
M < 0.3 x T
The amount of ballast that should be applied according to the
formula is the minimum required for circulation on the road. If for
reasons of tractor performance or to improve the set-up of the
planting unit during operation it is thought necessary to raise
these values, please refer to the registration document of the
tractor to check its limits.
When the formula for calculating the ballast gives a negative
result it will not be necessary to add any weight. In any case, as
long as the limits of the tractor are respected, a suitable quantity
of weights may be applied in order to ensure greater stability
during travel.
The symbols have the following meanings:

3.4 SEED DISTRIBUTOR

A disk (1 fig. 13), chosen according to the size of the seed, is
assembled inside the distributors (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. 45).
