IMPLEMENTS

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).
N.B. - 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: when using the machine into the walking tractor version, the safety device (fig. 4,
no. 7) automatically disengages the PTO if the reverse gear is engaged. Do not tamper with
this device.
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 which can be attached to the rotovator 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 rotovator can be used with other implements. The mower bar is attached to rotovator
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. 13, no. 3) 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 subject to less strain and its working life will be longer. Clean the mower bar after every
working day, removing any remaining pieces of grass or earth; every now and then check that all
screws are tight.
