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 coupling.
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 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:
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 Fig. 14 for reference)
