Section 4
4.6 HITCHING THE TRAILER
DANGER
When hitching, there must be nobody between the
trailer and the tractor. When hitching the machine,
tractor driver must exercise caution and make sure
that nobody is present in the hazard zone.
When connecting the hydraulic or pneumatic lines to
the tractor, make sure that the hydraulic and pneu-
matic systems of the tractor and the trailer are not
under pressure.
Ensure sufficient visibility during hitching.
After completed hitching, check that the hitch pin is
properly secured.
IMPORTANT
The trailer may only be connected to an fully opera-
tional agricultural tractor, if all connections (electric,
hydraulic and pneumatic) and the hitch on the ag-
ricultural tractor meet the requirements of the trail-
er manufacturer. Ensure compatibility of oils in the
tractor hydraulic system and in the trailer hydraulic
system.
In order to hitch the trailer to the tractor,
perform the actions below in the sequence
presented.
• Visually inspect the technical con-
dition of the trailer.
• Immobilise trailer with parking brake.
Pull brake mechanism clockwise
until resistance is felt. Make
certain that chocks are placed
under one trailer wheel.
• Position agricultural tractor directly in
4.10
PRONAR T700M/1
front of the trailer`s drawbar eye.
• Using the support, set the drawbar at
such a height as to make it possible
to hitch the trailer.
• If the telescopic parking stand is
used, adjust the drawbar height by
rotating the crank in correct direction
(section 4.4).
• In the case of the shear hydraulic
support - figure (4.5), reverse the
tractor and connect the hydraulic
lines of the support to it. Then, by
controlling the selective control valve
in the tractor, set the height of the
drawbar eye to enable hitching the
trailer. When the drawbar eye height
is set, set the manifold lever in tractor
to "neutral" position.
• Reverse tractor, hitch trailer to ap-
propriate hitch on tractor, check hitch
lock protecting machine against ac-
cidental unhitching. If the agricultural
tractor is equipped with an automatic
coupler, ensure that the hitching op-
eration is completed and that drawbar
eye is secured.
• Fold the support and secure it
properly. If the telescopic parking
stand is used, raise the parking
stand and secure it with securing pin
