IMPLEMENTS

IMPORTANT

When connecting each implement to the attachment flange make sure both sides are perfectly
aligned. First hand-tighten the bolts then use a wrench to make them press on the flanging (fig. 3,
n. 7).
ROTARY TILLER
The rotary tiller is used to break the surface layer of the ground in order to increase its permeability
and at the same time to get rid of weeds. Till in first speed if the soil is hard and tough or in second
speed in soft, sandy soil. Working depth can be adjusted by lifting or lowering the central knife
positioned under the rotary unit. To increase the working depth move the central knife upwards. It
is recommendable to start tilling with the knife in the lowest position, and then to raise it if greater
depth is required (fig. 20).
Note: On hard soils the machine may jump forward. In this case set the central knife in the first
hole (fig. 20). Check that hoes are mounted properly.
CAUTION: In walking tractor version it is not possible to engage the reverse gear if the PTO
is engaged. Never disable the safety system.
CAUTION: Keep your hands and feet away from the rotary tiller hood when the engine is
running, rotation of the tiller is highly dangerous. Before performing any kind of operation
on the tiller (e.g. replacing hoes), ALWAYS SWITCH OFF THE ENGINE.
ROTARY TILLER SUPPORT WHEEL
It is very useful while transferring the machine, because it keeps the rotary tiller off the ground,
making transfer easier and less tiring (fig. 8).
CAUTION: Keep your hands and feet away from the rotary tiller hood when the engine is
running, rotation of the tiller is highly dangerous. Before connecting or removing the
support wheel, ALWAYS SWITCH OFF THE ENGINE.
PLOUGHS
Ploughs designed for this walking tractor have been especially developed to obtain good ploughing
without straining the operator. The models available are a single-share plough and an 180roll-
over plough (fig. 11). The latter is especially suitable when working backwards and forwards, such
as along rows of vines or fruit-trees. The depth of the furrow obtained may vary from 10 to 15 cm
depending on the terrain. Better results are obtained by fitting the 6,5/80-12 tyres and if necessary
the wheel-weights which increase the wheel grip (fig. 10).
FURROWER BEHIND THE ROTARY TILLER
This tool is mounted at the rear of the tiller and works in tandem with it. The furrower is designed to
produce irrigation and seed drills (fig. 26). For the coupling mount the bushing (fig. 9).
CAUTION: Keep your hands and feet away from the rotary tiller hood when the engine is
running, rotation of the tiller is highly dangerous. Before connecting or removing the
support wheel, ALWAYS SWITCH OFF THE ENGINE.
ADJUSTABLE FURROWER
The adjustable furrower (fig. 12 – combined with the frame for attachments) is specially designed
for preparing furrows for sowing and irrigation. It is mounted using the frame for attachments like a
plough on the back of the gearbox. The furrow width can be regulated from a minimum of 10 cm to
a maximum of 30 cm, by changing the position of the two wings. The depth can be varied from 10
to 20 cm. When working on particularly hard soils, till before furrowing. Better results can be
achieved by fitting the 6.5/80-12 tyres and the wheel extensions (fig. 6).
