4) Lift the equipment until the two parts are perfectly coupled along
the triangle guides.
5) Lock the coupling using the M12x80 screws provided (B Fig.
10).
6) Fix the "scattering" bar to the implement (C Fig. 11).
For VITIGREEN 1300, adapt the bar (C) by cutting along the
reference marks on the bar itself (Fig. 11).
7) Connect the cardan shaft (Fig. 12) to the rear roller transmission
on the rotating harrow, locking into position using the safety pin
provided. Find the correct connection position in the seeding
table (U1 - U2).
8) Slip out the parking feet (Fig. 13).
9) Lower the lift and place the combined equipment in an operating
position.
3.1.4 UNHITCHING THE PLANTING UNIT FROM THE
EQUIPMENT
DANGER! Be very careful in following the instructions for the
whole operation.
1) With the machine raised, insert the parking feet.
2) Slide the cardan shaft out from the transmission (U1-U2, Fig. 12)
and then remove the scattering bar from the rotating harrow.
3) Remove the locking screws (B, Fig. 10) from the snap cou-
pling.
4) Slowly lower the equipment.
5) The equipment can only be removed when it has been totally
disengaged.
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
diffi culties (rearing up or side-slipping of the tractor). The condition
of equilibrium can be restored by placing a suffi cient number of
ballasts on the front of the tractor so that the weights on the two
tractor axles are distributed suffi ciently 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:
Z > (M x s)-(0.2 x T x i)
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. Check that the tractor tyres are suitable for
the load. The symbols have the following meanings: (please see
