The machine is equipped with 2 sequential valves. The valves allow to power all three actuators of the
2-sided operation in the tractor without the need of switching the hydraulic conduits.
The hydraulic system is designed in the following way:
•
First, the hitch actuator will be shifted,
•
then, the side arms actuators will be shifted.
SEQUENCE I
Starting position - transportation position.
Transferring the pressure in the hydraulic system from the 1st hydraulic output, the hitch actuator will
be activated, tilting the machine towards the tractor, and then, the side arms actuators, making the
arms drop on the ground.
SEQUENCE II
Starting position - working position.
Feeding pressure in the hydraulic system from the 2nd hydraulic output, the hitch actuator will be
activated, tilting the machine backwards to the vertical position. By stopping the pressure feed, we
obtain the clearance allowing to maneuver on the grassland without the need of lifting the side arms.
Then, feeding pressure in the hydraulic system from the 1st hydraulic output will result in returning
the machine to the working position.
SEQUENCE III
Starting position - working position.
Feeding pressure in the hydraulic system from the 2nd hydraulic output, the hitch actuator will be
activated, tilting the machine backwards to vertical position, and then, the side arms actuators make
the side arms lift to the transportation position. The actuator locks should activate automatically.
SEQUENCE IV
Starting position - transportation position.
By feeding pressure in the hydraulic system from the 1st hydraulic output, the hitch actuator will be
activated, tilting the machine towards the tractor - obtaining the rest position of the machine.
