and remove the ignition key from the control panel.
25) It is absolutely forbidden to stand between the tractor and the machine (Fig. 5) when the engine is running and
the propeller shaft is engaged without having first engaged the hand brake. Keep a safe distance from the
rotating/moving parts at work to avoid being hit by possible flying stones, etc.
26) Always set the lift control lever to the locked position before coupling or releasing the implement from the threepoint coupling.
27) The category of the implement coupling pins must correspond to that of the lift coupling.
28) Take care when working near the lift links. This is a very dangerous zone.
29) It is absolutely forbidden to stand between the tractor and the implement when manoeuvering the lift control
from the outside (Fig. 5).
30) Fix the side lift links with the relative chains and idlers during the transport phase.
31) Set the control lever of the hydraulic lift to the locked position during road transport with the implement raised.
When hoisting from the ground, the joints of the propeller shaft are bent to more than 40° (power takeoff turned
off). Detach the shaft from the power takeoff of the tractor.
32) Only use the propeller shaft recommended by the Manufacturer.
33) Frequently and periodically check the propeller shaft guard.
It must always be in an excellent condition and well-welded.
34) Take great care of the the propeller shaft guard, both in the transport and work positions.
35) The propeller shaft must only be installed or dismantled whilst the engine is off.
36) Take great care to ensure that the propeller shaft is correctly assembled and safe, and carefully check the
locking both on the P.T.O. of the machine and on the P.T.O. of the tractor.
37) Use the supplied latch to prevent the propeller shaft guard from turning both on the machine's and on the
tractor's side.
38) Before engaging the pto, ensure that there are no persons or animals in the field of action of the machine and
that the selected running rate corresponds to the permissible value.
Never exceed the recommended maximum rate.
39) Never engage the pto when the engine is off.
40) Always disengage the pto when the propeller shaft is set at an excessively open angle (never beyond 10
degrees - Fig. 6) and when it is not in use.

52) The instruction manual delivered toghether with the machine by the dealer must be kept for as long as the
machine lasts.
ATTENTION
In the event a tractor is used that has no pressurized, soundproof cabin the operator must use individual
methods of protection.
- Protective headphones for noise in case the standard levels of exposure are exceeded.
- Anti-dust mask, if a considerable quantity of dust is raised caused by the type of product cut, by very dusty earth,
or by the use of an open machine.
16
3.0 USE INSTRUCTIONS
3.1 TRANSPORT
If it becomes necessary to transport the machine for a long distance, it can be loaded onto a railway wagon or a
truck. For this purpose, consult «Technical Features» for weight and specific dimensions. The latter are very useful
to check the possibility of driving along all types of roads.
The machine is generally supplied in a horizontal position with no packing material. It is therefore necessary to use a
system of hoisting with a crane and cables, or chains of adequate capacity, hooking onto the oachine at the hoisting
points marked with the «hook» symbol (S-12).
CAUTION
Before proceeding to the hoisting operations, make sure that any any mobile elements of the machine
(wheels, 3rd point hitch...) are blocked.
Make sure to use a crane with an adequate hoisting capacity to lift the machine.
Hoist the machine with extreme caution and transfer it slowly, without jerks or abrupt movements.
DANGER
The operations of hoisting and transport can be very dangerous if not carried out with the maximum
caution; persons not directly involved should be moved away. Clean, evacuate the area and delimit the
transfer zone.
Check the state, condition and suitability of the means at disposition.
Do not touch suspended loads, keeping them at a safe distance.
During transport, the loads should not be raised more than 35 cm. from the ground.
It most be further ascertained that the operational area is free of obstacles and that there is sufficient
«escape space», meaning an area which is free and secure into which one could move rapidly in case a
load should fall.
The surface on which the machine is to be loaded must be horizontal in order to prevent possible shifting.
Once the machine is positioned on the vehicle, make sure that it remains blocked in its position.
Fasten the machine on the platform of the vehicle by means of cables suitable for the mass which must be blocked
(see «Technical Features» for the weight).
The cables must be firmly fastened to the machine and pulled tight to the anchorage point on the platform.
Once transport has been carried out and before freeing the machine from all its fastenings, make sure that its state
and position are such as not to constitute danger.
Remove the cables and proceed to unloading with the same means and methods used for loading.
Transit and transporting on the public highways
When driving on the public roads, fit on the rear reflector triangles, side lights and flashing beacon and always make
sure that you comply with the Highway Code and any other applicable regulations.
ATTENTION
Before driving on to the public roads with the machine hitched to the tractor, make sure that the devices
listed above and/or the slow vehicle signal and/or the projecting load signal operate correctly.
These indicators must be affixed to the rear of the implement in a position where they can be clearly seen by
any other vehicle that drives up behind.
17
3.0 USE INSTRUCTIONS
3.2 MACHINES SUPPLIED PARTLY BROKEN-DOWN
Owing to their size, the machines may be supplied with detached parts, always fixed in the same pack.
Normally, the parts that are detached and subsequently assembled by the customer are the 3rd point mounting
which, depending on the type, weighs.
Execute these installation operations with the utmost care.
Refer to the list of parts in the Spare Parts Catalogue. In particular, apply the screw tightening torques as
listed in the Chart on page 22.
3.3 BEFORE USE
Before starting the machine, check that:
- The machine is perfectly in order, that the lubricants are at the correct levels (see «Maintenance» chapter) and
that all parts subject to wear and deterioration are fully efficient.
WARNING
The accident prevention guards are delivered dismantled for shipping volume needs. Before
commissioning the machine, check to be certain that all accident prevent guards are in place and correctly
installed.
- The protection unit, consisting of the coupling (8 Fig. 3) that acts as a clamp (7 Fig. 3) locked by the bracket and
by the screws, is fixed to the square front pipe by the bolts and should be positioned on the Front and Rear
Brackets on the body frame, one on the Front and Rear Brackets on the body frame.
Strictly comply with the following instructions to achieve the best performances.
WARNING
None of the following servicing, adjustment and preparation operations must be carried out unless the pto
is disengaged, the machine is on the ground, the tractor engine is off and the tractor itself is safely at a
braked.
3.4 HITCHING TO THE TRACTOR
The machine is coupled to the tractor with the machine on the ground. The ground area should be flat.
All the machine can be attached to any tractor with a class 1 or 2 universal 3-point hitch.
Depending on the precise dimensions of these two types of hitches, find the best position for the machine by moving
the plates (1 Fig. 7) along the square tubular and inserting the pin (2 Fig. 7) in the holes corresponding to the correct
diameter for the tractor's parallel arms.
IMPORTANT
The plates (1 Fig. 7) must always and only be mounted as shown in Fig. 7 with the holes towards the front of
the square tubular.
The Manufacturer declines any liability for damage to the machine or the tractor if this essential installation
requirement is not observed.
DANGER
Application of any implement to a tractor is a very dangerous operation and must only be carried out with
the utmost care in compliance with the instructions.
The correct tractor/machine position is established by setting the implement at such a distance from the tractor that
the universal coupling remains 5-10 cm from its maximum closing position. Now proceed in the following way:
1) Near the lift bars, setting them in the most suitable plates (2 Fig. 7). Insert the pin (1 Fig. 7) into the relative hole
and lock in place with the snap-in split pins.
2) Lock the lift links using the relative chains and couplings parallel to the tractor.
This operation must be carried out to prevent the machine from moving in a horizontal direction.
3) Engage and check that it is perfectly locked on the pto. Check that the guard is free to turn and tight the guard
with suitable chain.
4) Connect the upper third-point and correctly regulate by means of the adjuster (1 Fig. 8), checking that the upper
surface of the machine (A Fig. 8) is parallel to the ground (B Fig. 8).
This is very important since it achieves parallelism between the axis of the machine and that of the tractor pto.
When the implement operates in these conditions, there will be less stress on the pto itself while the propeller
shaft and implement will be much less subject to wear.
5) Position the support foot as shown in the figure 9.
18
3.0 USE INSTRUCTIONS

Fig. 7
6) Besides supporting the Levelling bonnet and acting as a shock absorber for it during road transport, the spring
ram (Fig. 10) prevents the steerage hoe from overturning when parking. The effect of the levelling bonnet on the
soil can be increased or decreased depending on the position, established by the split pin, Nut and bolts (Fig.
10) in the various holes in the ram tube ( Fig. 10).
19
3.5 CHECK THE LIFTING CAPACITY AND STABILITY OF THE TRACTOR TO
WHICH THE MACHINE IS HITCHED
Assembly of a implement on the tractor will shift the weights on the axles (Fig.11).
It is there fore advisable to add weights to the front part of the tractor in order to balance the weights on the axles
themselves.
The ballast required is calculated by means of the following formula:
Z > M x S - 0.2 x T x i
d + i
S = S1 + S2
If the implement is hitched to approved agricultural tractors registered before 6th May 1997, also check to make
sure that the following relation has been complied with:
M < 0.3 x T
I = Tractor wheelbase (cm).
d = Distance between front axle and center of gravity of ballast (cm).
T = Weight of tractor + operator (75 kg)
Z = Weight of ballast (kg)
M = Weight of implement (kg)

S2 = Distance between bar hitch hole and center of gravity of machine (cm) (Fig. 11).
3.6 PROPELLER SHAFT
Propeller shaft adaption
The Propeller shaft, supplied with the machine, is of standard length. Therefore it might be necessary to adapt the
Propeller shaft.
In that case, before doing anything, consult the Manufacturer for the eventual adaptation.
Hitch the machine to the tractor and stabilize the tractor's third point with the device installed for that purpose (bar,
chain, etc.).
Disengage the tractor's PTO and turn off the engine.
Connect the driveline shaft to the tractor's PTO.
Connection is correct when the machine is horizontal in the operating position.
To achieve this, increase or decrease the length of the top bar of the hitch (B Fig. 12) so as to set the axis (X Fig. 12)
of the housing's grooved ring nut parallel to the ground.
20
Inspections at work:
- The two angles formed by the fork axes and the axis of the sliding tubes will be equal and must not exceed 10°.
- The sliding tubes (A Fig. 13) must overlap by at least 15 cm (Fig. 13).
Inspections in the raised position:
- Proceed with a lifting action (tractor PTO disengaged).
- The two tubes of the driveline shaft must not fully overlap. There must always be a safety travel (B Fig. 13) of at
least 4 cm.
- The angles of the drivelines must not exceed 40°.
If these two results are not obtained:
3.0 USE INSTRUCTIONS
Fig. 12
Fig. 13
- Shorten the sliding tubes by the same extent (Fig. 14 and 15), deburr and trim, then grease the inside of the
outer tube.
- Make sure that the upper hitch bar is as parallel as possible to the lower bars of the hitch.
If this is not sufficient, correct the way the top link of the hitch couples to the tractor or machine, as necessary, or
at least considerably attenuate, the jolts to which the driveline shaft is subjected during the lifting phase.
- If errors have been committed, disengage the tractor's PTO before lifting the machine.
Repeat these inspections when the machine is hitched behind another tractor.
CAUTION
When the propeller shaft is fully extended, the two tubes must overlap by at least 15 cm.
When fully inserted, the minimum play must be 4 cm. (A Fig. 13).
CAUTION
If the implement is used on another tractor, always check the before and that the guards completely cover
the rotating parts of the propeller shaft.

CAUTION
This inspection must be performed at the beginning of each new working season.
Driveline with safety limiter and shear bolt
The limiter, inserted in the cardan joint, is equipped with a safety bolt that is set for an average force.
Whenever unduly resistant obstacles cause the bolt to shear, it must be replaced by a new bolt, of the same size and
material and grade.
If the bolt, inserted in hole, shears repeatedly, then we recommend using the higher grade bolt ( Fig. 18).
CAUTION
Avoid frequent and lengthy overloads.
The driveline is supplied calibrated by the Manufacturer.
Do not tamper with the device if operational faults occur.
Contact the driveline supplier or a specialized center if necessary.

- Side Adjuster Skids.
- Draft and Position Lever on Tractor.
DANGER
Turn the adjustment handle only when the tractor is at a standstill and with the power take-off
disconnected.
Do not carry out this adjustment by operating from the tractor.
Machine with skids
To adjust working depth on this type of machine you must loosen the adjustment screw (1 Fig. 19) and raise or lower
the skid the desired amount. Then retighten the srew.
Both skids should be subjected to this operation which will vary according to the type of soil.
3.8 SIDE TRANSMISSION
Side gears drive
The rotor can be operated by a set of side gears (5 Fig. 3) housed in a special casing with thick walls able to give the
transmission considerable sturdiness.
3.9 HOE BLADES
The hoe blades with which the machine is equipped can work soils of normal conformation.
Check the degree of wear and condition of the hoe blades each day.
If the blades should accidentally bend (or break) during work, they must be immediately replaced.
