3.0 RULES OF USE
To obtain the best performance from the equipment, carefully
follow what is set out below.
ATTENTION
The following maintenance, adjustment, and work preparation
operations must be performed with the tractor off and locked
firmly in position with the key removed from the dashboard
and the seeder positioned on the ground.
3.1 ATTACHMENT TO THE TRACTOR
The seeder may be attached to any tractor fitted out with a three-
point universal hitch.
The attachment to the tractor is a very dangerous phase.
Be very careful in following the instructions for the whole
operation.
The correct positioning of the tractor/seeder is determined by
placing the unit on a horizontal surface.
1) Connect the seeder to the tractor's three point attachment;
the pins must be fastened with the appropriate pegs. Use
the adjustment stay-bolts (1 Fig. 7-8) to ensure that the seeder
is perpendicular to the ground (Fig. 8), check to make sure
that the position indicator on the left side (A Fig. 8) is in the
correct (vertical) and act on the third point if required.
2) Block the movement of the parallels of the tractor on the
horizontal plane using the stabilizers provided, so eliminating
the side swaying of the equipment.
During the work, regularly check that the equipment is
perpendicular.
ATTENTION
Always follow the indications recommended by the
Manufacturer for the transport of the seeder.
3.2 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:
