Position agricultural tractor directly in front of drawbar eye.
Reverse the tractor and, if hydraulic support is used, connect the conduit to
the support according to label (6) – table (2.1) (straight hydraulic support or
folding hydraulic support).
Using the support, set the drawbar at such a height as to make it possible to
couple the machines.
If the hydraulic support is used, operate the manifold in the tractor to
raise or lower the trailer drawbar until the correct height is achieved.
If the telescopic support is used, adjust the drawbar height by rotating
the crank in proper direction - see chapter 4.2.1.
Reverse tractor, hitch trailer, check coupling lock protecting machine against
accidental unhitching.
If the agricultural tractor is equipped with an automatic coupler,
ensure that the hitching operation is completed and that drawbar eye
is secured.
Fold the support and secure it properly.
If the telescopic support is used, raise the support as described in
section 4.2.1 and secure it with securing pin (5) figure (4.1).
After folding the hydraulic support, close the support valve (3) - figure
(3.10) or (3.11) and set the manifold lever in the tractor in "neutral"
position.
When the trailer is hitched, the hydraulic folding support must be
folded and secured with lock pin (4) figure (3.11).
Turn off tractor engine. Ensure that unauthorised persons do not have access
to the tractor cab.
The trailer hitched to the tractor must be level. Empty trailer may be slightly
tilted forwards from the level (about 50mm).
If the trailer is not level, adjust the position of the trailer drawbar
hitching eye or the tractor hitch.
