IMPLEMENTS

IMPORTANT
While mounting the different attachments make sure the machine flanging and the attachment
flanging are perfectly aligned. First hand-tighten the bolts then use a wrench to make them press
on the flanging (fig. 4C).
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 rid of weeds. Till in first speed if the soil is hard and tough or in second
speed in soft, sandy soil. The working depth can be adjusted by lifting or lowering the central knife
situated under the rotary unit. The tiller cover position will change at the same time. Raise the knife
to increase the depth. Start work with the knife in its lowest position, and then raise it if greater
depth is required (fig. 4B).
Important: on hard soils the machine may jump forward. In this case lower the central knife
and fit it into the third hole (fig. 4B). Check that the blades are fitted correctly (see fig. 9).
CAUTION: while operating in the walking tractor version, if the operator engages the
reverse gear the safety system device (fig. 4, n. 7) immediately disengages the PTO. Do not
tamper with this device.
CAUTION: Attention! Rotating blades are very dangerous, never put hands or feet under the
tiller cowling when the engine is running. ALWAYS SWITCH OFF THE ENGINE before
performing any kind of repair or maintenance operation on the tiller (e.g. replacing hoes).
ADJUSTABLE FURROWER
This implement is specially designed for preparing furrows for sowing and irrigation. It is mounted
like a plough or a rotary tiller on the implement flange 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. The results obtainable can be improved by fitting the 5.00-12 tyres and if
necessary the wheel-weights which increase wheel grip (fig. 10).
MOWER BAR
The mower bar (fig. 11) which can be attached to the walking tractor has a central or side control.
Its strength and high performance make it the best way of mowing small pieces of land when it
does not make economic sense to purchase a motor mower which would remain unused for most
of the year, while a walking tractor can be used with other implements. The mower bar is attached
to walking tractor implement frame instead of the rotary tiller and fixed using the same two nuts.
The handlebar must be turned 180towards the engine. Caution: Before turning the handlebar
place the drive clutch lever into the forward gear (fig. 3A, no. 2) then remove the control levers
form the lower eyelets (fig. 3, no. 28). Once the handlebar has been turned, insert the control
levers into the upper eylets (fig. 3, no. 29). To make the blade work the safety device must be
positioned as shown (fig. 2A).
Important: when reconnecting the rotary tiller, the safety device must be set into the
original position. We do not accept any responsibility for failure to follow this rule (fig. 2).
Maintenance: grease the cross pins every 8 working hours through the grease nipples on the
swinging crank. Grease the mower bar swinging bushing every 50 working hours through the
grease nipple under the swinging protection. Keep the blade ledger plates properly adjusted. They
must be neither too tight, so that they block the blade, nor too loose so that there is too much
clearance between them and the blades. To adjust the ledger plates in both directions loosen the
locking bolts (fig. 12) and adjust the pressor screw. The ledger plates should be replaced when
worn even if they are still able to apply pressure against the blades. Regulate the clearance
between the blade and the strip by loosening the screws fixing the plates pressing the strip and
moving the strip forward until it touches the bar which supports the nailed blade section. Then
retighten the pressing plates. To remove the blade take off the L-shaped blade coupling by
removing the two screws (fig. 12) and slip off the blade. Take care to tighten the fixing screws of
the coupling after assembling the blade again. Always use sharp blades: the machine will be
