Cardan Shaft Adaption; Stability Of Mower And Tractor During Transport - Gaspardo FBR Plus Gebrauch Und Wartung

ENGLISH

3.0.4 CARDAN SHAFT ADAPTION

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 fully extended, the two tubes must
overlap by at least 15 cm (A, Fig. 17). When fully inserted,
the minimum play must be 4 cm (B, Fig.17).
- If the implement is used on another tractor, always check
the above and that the guards copletely cover the rotating
parts of the cardan shaft.
ATTENTION
Comply with the manufacturer's instructions when
transporting the mowing machine.

3.0.5 STABILITY OF MOWER AND TRACTOR DURING
TRANSPORT
When a mower is coupled to a tractor, so becoming an integral
part of it for the purposes of road travel, the stability of the mower-
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:
The symbols have the following meanings (please see Fig. 18
for reference):
M (Kg) Mass weighing on arms off hoist with full load (weight +
mass, see cap. 1.2 Identification).
T (Kg) Mass of tractor.
Z (Kg) Total mass of ballast.
i (m) Tractor wheelbase, that is, the horizontal distance
between the tractor axles.
d (m) Horizontal distance between the centre of gravity of the
ballast and the front axle of the tractor.
s1 (m) Horizontal distance between the inferior point of
attachment of the equipment and the posterior axle of
the tractor (equipment supported to the ground).
s2 (m) Horizontal distance between the barycentre of the
equipment and the inferior point of attachment of the
equipment (equipment supported to the ground).
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
mower 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.
