Installing the Disc System: Hydraulic System Connections 25
INSTALLING THE DISC SYSTEM
DUAL DISC HYDRAULIC SYSTEM
PRESSURE RELIEF VALVE
The cylinders should be mounted in mirrored positions. The ports on the piston rod side of the cylinders must be
connected to each other (Figure 3 on page 20). In addition, two pressure relief valves need to be installed in the
correct position in the system. The pressure relief valves are pre-set. Do not change the valve settings.
The mounting sequence of the cylinders is as follows:
1. Mount the fixed cylinder (innermost hole on the mounting plate) on the right side of the implement and then
put the disc in the straight forward position.
2. Then mount the adjustable cylinder on the left side (outermost hole on the mounting plate) and also put this
disc in the straight forward position.
3. Connect the hydraulic hoses as shown in Figure 12 on page 27. The pressure relief valves have three ports. Two
P-ports and one T-port.

4. The angle sensor should be mounted on the right side, with the fixed cylinder.
5. After installing all hydraulics, flush the system by steering left and right several times. Keep on steering, when
the cylinders are at the end of their stroke to flush all air out.
6. When all air is out, position the right disc in the mid (straight ahead) position.
7. Check that the distance between the discs at the front and the rear is the same. Adjustments to the adjustable
cylinder to achieve that the discs are parallel.
