Stability of sickle bar mower and tractor during transport
When a sickle bar is coupled to a tractor, so becoming an integral part of it for the purposes of road
travel, the stability of the sickle bar-tractor complex may change and cause driving or operating dif-

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:

(d+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 sickle bar
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:
