GENERAL SUMMARY OF SAFETY AND ACCIDENT
PREVENTION INSTRUCTIONS
Read all the directions carefully before using the machine. When in doubt, seek
advice from the manufacturers.
The manufacturing company declines all responsibility for non-compliance with the
following safety and accident-prevention instructions.
1- Pay attention to the danger signs and symbols in this manual and on the machine.
2- Do not touch moving parts.
3- All work on the machine (including adjustments) must always be carried out with
the tractor immobilized and the engine switched off.
4- On no account may persons or animals be carried on the machine.
5- Driving the tractor with the machine connected is absolutely forbidden to persons
lacking suitable experience, or who are in poor health, or who do not have a
suitable driving license.
6- All accident-prevention measures recommended in this manual should be
scrupulously observed.
7- Connecting the machine to the tractor creates a different weight distribution on the
axles and so it is essential to ensure that the tractor-machine combination is stable
in all anticipated working conditions. It is therefore necessary to have exact
instructions from the tractor manufacturers. If such instructions are not available,
suitable tests should be conducted in safe conditions in order to assess stability.
8- Once the machine is connected, it can only be controlled through a Cardan shaft
complete with the required overload protection and guard secured with the
appropriate small chains. Be aware of the rotational direction of the Cardan shaft.
9- Before operating the tractor and machine, check that all transport and operational
safety devices are complete and working.
10-When driving on public roads, you should comply with the Highway Code
regulations for the country concerned.
11-Do not exceed the tractor axle maximum weight and the total mobile weight. Heed
transport regulations.
12-Before starting work, familiarize yourself with the control devices and how they
work.
13-Wear suitable clothes. Do not wear clothing which is loose or which could
become entangled in rotating or moving parts.
14-Connect the machine to a suitably powerful tractor by using an appropriate lifting
unit and in accordance with instructions.

15-Take maximum care when connecting and disconnecting the machine to and from
the tractor.
16-The machine and any road transport attachments must bear the appropriate signs
and symbols and have suitable protection.
17-Never leave the driving seat when the tractor is running.
18-It is extremely important to appreciate that road holding, steering and braking may
be significantly affected with the machine attached.
19-When turning corners with the machine attached, be aware of the fact that the
centrifugal force will alter due to the change in the center of gravity.
20-Before engaging the power takeoff check the preset revolution speed. Do not
change speed from 540 rpm to 1000 rpm.
21-Under no circumstances should anybody stand near the machine or any moving
parts. It is the duty of the operator to ensure that this requirement is respected.
22-Before leaving the tractor, lower the machine with the lifting unit, stop the engine,
apply the parking brake and remove the ignition key from the instrument panel.
23-Under no circumstances should anybody go between the tractor and the machine
when the engine is running and the Cardan shaft is engaged, especially without
first having applied the parking brake and placed chocks against the wheels.
24-Before connecting or disconnecting the machine to or from the 3-point linkage,
put the lifting unit lever into the locked position.
25-The connection pins on the machine must match the connection sockets on the
lifting unit.
26-During transport, secure the lateral lifting arms with the appropriate chains and
tighteners.
27-When the machine is raised during road transport, put the tractor's hydraulic lifter
lever into the locked position.

excellent condition and securely fixed.
30-It is important to ensure that the protection on the Cardan shaft is complete.
31-Connection and disconnection of the Cardan shaft must be carried out with the
engine switched off.
32-Pay particular attention to the correct connection and safety of the Cardan shaft
and the power takeoffs on the machine and the tractor.
33-Prevent the cardan shaft protection from rotating using the chains supplied.
34-Before engaging the power takeoff, make sure that there are no people or animals
in the vicinity and that the selected engine speed corresponds to that permitted.
Never go above the maximum permitted.
35-Do not engage the power takeoff when the engine is not running.
36-Always disengage the power takeoff when the Cardan shaft is at too wide an angle
(it should never be more than 35° Fig. 3.2) and when it is not in use.
37-Only clean and grease the Cardan shaft when the power takeoff is disengaged, the
engine is off, the parking brake is applied and the ignition key is removed.
38-On disconnecting the Cardan shaft, replace the protective hood on the power
takeoff shaft.
39-Prolonged use of the machine can cause the drive boxes to become hot. To avoid
any risk of getting burnt, avoid touching these areas both during se and some time

5) ADJUSTMENT,PREPARATION AND USE
INTRODUCTION
Connection to the tractor is highly dangerous. Take great care and carry out the entire
operation in strict compliance with the following instructions. Nobody should go near the
area between the tractor and the machine. Check that all warning and danger signs are in
place and legible. Check that the tractor is in good running order. Refer to the tractor
operator’s manual.
ATTACHMENT OF MACHINE TO THE TRACTOR
Note: If a safety system is provided, this should be fitted to the machine shaft,
not to the tractor shaft. Apply the end 1 of the cardan to the socket on the machine

18
2(see Fig. A-F). Connect the lifting arm 3 to the pins 4 of the machine and fasten
with the split pins 5 (see Fig. B-C-D-F-G). Connect the tie-rod (or hydraulic cylinder)
6to the 3rd point hitch and fasten with the pin 7 and the split pin 8. Hitch 11 has two
holes 12-13 to fit the variety of connecting tie-rods pins. (see Fig. B-C-E-F-H-I).
Connect part 9 of the cardan to the socket on the tractor 10 (see Fig. B-C-F-H).
(Fig. F-G-H are for the front-attachment models)
CONNECTING CARDAN SHAFT INFORMATION
More detailed information may be found in the cardan shaft manual which, together
with this manual, is an essential part of the accident-prevention documentation. It is
your responsibility to read and comply with this documentation. If information given
in this manual should conflict with that given in the cardan shaft manual, you should
follow the instructions given by the cardan shaft manufacturer.
After having connected the cardan shaft to the shaft of the machine gearbox and to
the tractor PTO as described previously, make sure that when working with or
transporting the mower no situations occur in which the maximum extension or
minimum contraction of the cardan shaft does not exceed the conditions described in
the notes below.
During both transport and use, avoid conditions where the cardan shaft is extended to
the maximum. In all working conditions, the telescopic tubes must overlap by at
least 1/3 of their length (fig. 1). Conversely, when the cardan shaft is contracted to
the maximum, there should still be a gap of approximately 50mm-2” (Fig. 2).
It is absolutely forbidden to use the machine if the application of the
cardan shaft isn’t included in the previously described and illustrated
conditions (see figure 1-2).

TRANSPORT INSTRUCTIONS FOR FINISHING MOWERS
Once the machine is attached to the tractor, before proceeding with the transport check to
make sure all attachment pins are fully inserted in place and correctly fastened with the
fastening pins. For transport, the machine must be raised by the tractor power-lift. If when
raised the position reached is not satisfactory, adjust the power-lift adjustment rods 1-2.
Check that the cardan shaft 3 does not interfere with the 3rd point hitch when the machine is
raised.
TRANSPORT BY ROAD
After the machine has been attached to the tractor as previously described and before
transporting it to or from fields or any other workplace, the following instructions should be
heeded:
Before setting off with the machine attached to the tractor, check the local road transport
regulations. During transport keep the machine fully raised with the power takeoff
disengaged and the lifting unit immobilised. Ensure that nobody leans against, or climbs on
to, the machine during transport. The finishing mowers is an agricultural machine NOT
designed for persons or goods. Consult the tractor maintenance and user manual where
necessary. Maintain constant control over the vehicle and ensure that you know how to stop
the tractor quickly and switch off the engine. When on a public road, observe all highway
code regulations. Drive near the edge of the road and try not to obstruct traffic. Do not park
the tractor and/or the machine where it might obstruct, or be a danger to, any public right of
way. Avoid going onto a public road if the tractor or machine is very dirty you could leave a
trail of soil, grass and other matter which could dirty the road and obstruct normal traffic.

20
USE IN THE FIELD
Once the machine is prepared, before beginning work read the chapter on
“General Instructions for Use in the Field” (see pg.27)
PRELIMINARY CHECK
Check that, depending on which is the case, the rotation direction “A”
(counterclockwise – standard) or “B” (clockwise) of the PTO of gearbox 1 matches
that of the tractor PTO 2.
Check that, depending on which is the case, the number of RPMs 540-1000-2000
counterclockwise or 540-1000-2000 clockwise of the PTO of gearbox 1 matches that
of the tractor PTO 2.
Check that, regardless of the number of RPMs and the rotation direction of gearbox
PTO 1 and tractor PTO 2, the rotation direction of the blades 3 is always that
indicated by the arrows “C”.
Note: These preliminary checks must be done for machines with rear grass ejector as
well as for machines with side grass ejector and for front finishing mowers.
