Hydraulic system
Bale wrapper's hydraulic system is controlled by means of a manifold controlled from a control unit. The system is pow-
ered by a tractor hydraulic pump with the option of return by one extra line of a so
-
called
“
free drain
”.
The hydraulic sys-
tem is under high pressure during the operation of the bale wrapper, so the condition of the connections and hoses must
be checked regularly. Operation with a leaking or damaged system is not permitted. In case of a malfunction, the machine
must be taken out of service until it is repaired. Before carrying out repair or maintenance, make sure that the system is
depressurised. Hydraulic oils should be stored in original containers or in packaging adapted to their storage, paying partic-
ular attention to the effect of hydrocarbons.

SECTION I
By controlling the pressure on Section I, used for bale lift actuator movement, you can raise and lower the bale loading
arm, which places crop between the table rollers on the rotary frame.
SECTION II
It uses a hydraulic motor to drive the gears activating the rotation of the rotary frame and the table rollers assembly.
SECTION III
It is used to move three actuators:
•
film dispenser actuator, which pulls the film to be cut off,
•
telescopic tilt actuator for the rotary frame,
•
bale tipper actuator used for capturing and putting bales down.
SECTION IV
It drives the cut and hold actuator, which is designed to perform two functions:
•
cut off the film from a bale to be put down,
•
hold the film on the side of the dispenser before the next cycle.
