OWNER'S MANUAL OF THE MULCH CULTIVATOR PF-PD

6.2.1. CHECKING THE TRACTOR LIFTING FORCE AND STABILITY

When an extra machine is added to the tractor, becoming a part of the tractor itself, as far as road
circulation is concerned, stability is different and driving and working become more difficult.
Depending on the composition of the machine, it is therefore advisable to add ballast to the front part of the tractor so
as to adequately distribute the weight on the axles.
On the front bridge of the tractor it must, in any case, burden at least 20% of the total mass tractor tool in march
order. It is however to hold present that, beyond to the appropriated one chosen the connection tractor-tool, the
application of ballasts in front position, the limits and with the modalities indicated from the constructor of the
tractor,can improve of the stability . Moreover, with firm tractor it must be made to come down to earth the tool
avoiding therefore possible involuntary reductions, improving at the same time, the stability.
