3.5. Mounting the control set for dual
disc with two cylinders
In the case of two cylinders (hydraulic track
rod), one cilinder should be non-adjustable and
the other should be adjustable (Figure 19 and
Figure 21).
Only use two cylinders if a track rod is not
possible in the structure of the implement. A
mechanical track rod is preferred.
Take account of the working depth of the disc
and the position of the disc leg on the
attachment. The disc legs are provided with
several holes in order to adjust to the required
working depth.
Construct a sturdy frame from thick-
walled tubing of at least 80 x 80 cm.
3.5.1. Hydraulic system
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 19). 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.
