Translation of the Original Instructions
QUICK COUPLING
The snap coupling is designed to allow various implements to be hitched to the machine easily; the
implement is disconnected by simply pulling a lever, without the aid of spanners. This accessory
consists of two parts, one fixed to the machine and the other to the implement. Users are therefore
advised to purchase just one piece for the machine, and one for each implement (fig. 19). Grease
every 50 hours. It can be of two types: 50mm and 60mm.
CAUTION: Never use the tiller with the quick coupling, because the tiller would be too near
to operator's feet.
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.
20).
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. 21).
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.
ALL PURPOSE FLAIL
It is 68 cm wide, has a roller fitted with swinging Y-tines and is able to cut tall grass, tough stalks
and small shrubs into fine pieces; it can also twigs etc. after pruning. Used with mower blades
instead of the y tines, it gives excellent results on smooth lawns (fig. 22). Attention, danger! The
rotating blades of the all purpose flail are highly dangerous. Never put hands or feet under
the all purpose flail. Never clean the attachment when the engine is running.
The all purpose flail has to be connected to the implement flange using the quick coupling. The
handlebar must be turned through 180towards the engine (to carry out this procedure follow the
instructions outlined above for the cutting bar). To engage the all purpose flail the safety system
preventing the reverse gear and the PTO from being engaged at the same time (which is then
necessary with the rotary tiller) has to be deactivated. The operator has to remove the screw
(fig. 2). Important: if the rotary tiller is connected again, the safety system has to be brought
back to its original working condition. Grillo bears no responsibility in case of non-
compliance with this rule (fig. 2 – fig. 2A).
WHEEL EXTENSIONS
These help to widen the machine's track and increase its stability on crosswise slopes. They must
be fixed between the wheels and the hubs. The track is widened by 6 cm on each side (fig. 23).
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. 24). The wide steel 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.
