Translation of the Original Instructions
the reverse gear allow operation in the most difficult conditions without straining the operator and
with considerable time saving. The rotary cutter is fixed to the implement flange. The handlebar
must be turned through 180towards the engine; for this operation follow the instructions outlined
above for the cutting bar bar. The blade is driven by means of a bevel gear pair and is equipped
with a release mechanism and a brake blade. To adjust the cutting height vary the position of the
rotary cutter wheel, or of the lateral rams.
CAUTION: Rotating blades are very dangerous, never put hands or feet under the rotary
cutter. Do not clean the attachment when the engine is running.
Maintenance: Keep the lawn mower blade well sharpened: the cut will be better and the engine
will not strain. Check the gearbox oil level every 50 hours, removing the cap on the top, and make
sure that the oil level is within 50mm of the hole; if the level is lower add 80W/90 (API GL5 US-
MIL-L-2105D) gearbox oil. Change the oil once a year.
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.
TOWED TRAILER
The trailer (fig. 16) designed for the walking tractor is very useful for short hauls around the farm. It
is easy to handle, compact and very quickly hitched to the walking tractor. The trailer can be
attached directly to the machine by hitching it to the special towing bar (fig. 18) leaving the tiller in
place. Do not use the trailer on slopes greater than 5%. Passengers are not allowed. The
trailer cannot be used on public roads.
WHEEL-WEIGHTS
These are mounted on the wheel rims and fixed with two of the four nuts which fix the wheels
themselves. They increase the weight of the machine and thus its adherence to the ground, and
their use is recommended when working with the plough, the adjustable furrower, and even the
rotary tiller and the trailer if special performances are required (fig. 17).
TOW BAR
The towing bar is needed to attach the riding sulky or the trailer to the machine without removing
the rotary tiller. This attachment must be fastened to the towing hook on the walking tractor (fig.
18).
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. 10).
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.
WHEELS SPACERS
These screw spacers allow to expand the track and therefore improve the machine's stability on
slopes. They have to be mounted between wheels and hubs and they increase the track of 6 cm
on each side (fig. 21).
WIDE STEEL WHEELS
These wheels are particularly advisable when working on very hard soils with the rotary tiller. The
cross bars placed around the wheels dig into the ground, giving the machine a firm grip and
preventing the wheels from skidding (fig. 22). These wheels can be also used when tyres or the
narrow steel wheels, might skid or sink in damp or recently tilled ground. The use of wide steel
wheels is recommended, although only in these cases. Otherwise tyres are generally advisable; if
special grip is not required, they give the machine more even traction and form an elastic buffer
between the machine and the ground. Twin rings are also available for fitting to these wheels.
