WARNING
Before assembling any flail hedge mowers with
electric / electro-hydraulic controls and/or
heat exchanger on the tractor
YOU MUST
read the assembly instructions on the
electrical connections.
Failure to observe the said instructions faithfully may
result in considerable damage to the electrical system,
thereby invalidating the warranty of the same.
Given the importance and sensitivity of the electronics
we recommend that you have the electrical connections
made by a specialized workshop.

1 GENERAL INFORMATION
1.1 This operation and maintenance manual is intended for the professional user.
It is mandatory to follow these instructions in order to prevent events which could
endanger the operator’s and other people’s safety, apart from the correct
functioning of the flail-hedge mower. In case of doubt, do not experiment, call
FERRI after-sales service instead, or the specialized FERRI dealer.
1.2 Identifying the machine
Each frame and flail head is fitted with an identification plate; both the data
necessary to identify the model, the serial and part number to order spare parts or
after-sales service, are stamped on the plate (see FIG. 1).
1.3 It is strongly recommended to use genuine FERRI spare parts to avoid altering the
technical features of the flail-hedge mower. FERRI is not responsible for any
damage or injuries to persons or things due to unauthorized modifications.

2 TECHNICAL FEATURES
2.1 FERRI flail hedge mowers, from now on called also “machine”, have been designed
to shred materials growing or laying on the ground, e.g. grass, bushes, sticks and
shrubs. Never operate with the flail head lifted off the ground (proper use). Any
other use is considered improper and the manufacturer disclaims all responsibility
for any consequential injuries to person or things or damage to the machine.
“Proper use” also refers to the safety and maintenance rules provided for by the
manufacturer.

2.2.1 Hydraulic system
-Control circuit:
oil supplied by a gear pump is delivered to an electro-hydraulically controlled,
power-assisted distributor. This distributor in this configuartion controls all arm
operations and functions.
Arm movement speed is controlled by a 2-axis joystick, which is powered by a low-
pressure circuit (20 bar). The grip features different buttons which serve to operate
ON/OFF solenoids which in turn operate some of the controls.
The pressure signal sent by the joystick at the distributor inlet is of the proportional
type, thus making for smoother arm movement.
- Power circuit
In this instance the hydraulic system powering the flail hedge mower rotor is of the
closed-circuit hydrostatic type with axial piston pump and motor.
Unlike the open circuit, in which oil flow is broken by the tank, in the closed circuit
the oil flow is continuous because the outlet from the pump goes directly to the
motor and the outlet from the motor goes straight back to the pump.
Closed circuits offer many operational advantages:
-they can stop undamaged under full load with a minimum loss of power
-they accurately maintain a pre-set speed in the presence of resistive or
overwhelming loads
-their output is good, even when subjected to rather demanding duty cycles
-they can operate in two directions at controlled speed, without any major
interference from external loads
-when the control is disengaged, the flail holder shaft remains still
-their response time is faster than any other type of transmission
WARNING:
Frequent checking of the suction filter is recommended. Remember that the
life of hydrostatic transmission strongly depends on the degree of filtering of
the circulating oil!!

2.3 Noise
The sound level of this machine, as measured at the operator’s ear, ranges from
75.5 to 79.3 dB when the cab is closed, and from 80 to 85 dB when the rear window
is open. The acoustic power level is 104.5 LWA. When the sound level perceivable
at the operator’s ear ranges from 85 to 90 dB, the use of ear protectors is
recommended.
2.4 Width of cut
Fig. 3 shows the width of cut of the machine.
Dimensions are shown in Table 2.
2.5 Optional equipment
2.5.1 Flails
Depending on the different crops to be cut, the rotor can be changed and suitable
flails can be fitted and used:
- Multi-use flails for grass, shrubs, sticks and bushes up to 5 cm diameter.
N. B.: Do not use on stony ground
- Articulated “Y” flails for grass, shrubs and sticks up to 2 cm diameter.
10
- Hedgtrimming flails for grass or small shrubs up to 1 cm diameter.
- Hammer blades for wood up to 5÷6 cm diameter.
N. B. do not use on stony ground
- Articulated bootie flails for shrubs up to 2 cm diameter.
2.5.2 Locking the front axle of the tractor
(optional)
To increase the stability of the machine
(ONLY WHEN WORKING WITH THE
FLAIL HEDGE MOWER ARM) lock the
front axle of the tractor using switch 1
which controls valve 2which locks
hydraulic ram 3. (FIG. 4)
