FIGURE 4.2 Connecting the hydraulic system of the hydraulic support
(1) straight hydraulic support, (2) folding hydraulic support, (3) quick coupler - plug, (4) ball
valve, (O) "OPEN" valve position, (Z) "CLOSED" valve position
Using the parking support set the drawbar eye at such a height so it is
possible to hitch the machines.
Reverse tractor, hitch trailer, check coupling lock protecting machine against
accidental unhitching.
Raise the parking stand and secure it properly.
In case of mechanical support, adjust the drawbar eye height by
rotating the crank in proper direction - see chapter 4.3.1.
If the hydraulic support (folding or straight support) is used, set valve
(4) to open position (O) – figure (4.2) and start a proper section of the
manifold in the tractor in order to raise or lower the trailer drawbar eye
until a required height is achieved.
If the agricultural tractor is equipped with an automatic coupler, ensure
that the hitching operation is completed and that drawbar eye is
secured.
In case of the telescopic support with gear, follow the instructions
given in chapter 4.3.1.
