4.1 ADJUSTMENT OF DRAWBAR POSITION
Location of the drawbar should be se-
lected individually depending on the height
of trailer tyres and the height of the tractor
hitch to which the trailer will be coupled.
The height should be set in such a manner
as to ensure that the trailer hitched to
the tractor is level. Empty trailer may be
slightly tilted forward from the level (about
50 mm).
If you need to adjust the drawbar position,
perform the following steps - figure (4.1):
• immobilise trailer with parking brake,
• prevent the trailer from rolling by
placing chocks under the wheels,
• support the trailer on both sides of the
drawbar under the front beam of the
lower frame (7) by means of supports
of a suitable height and strength.
• the drawbar (1) should be supported
with telescopic support (2) or hy-
draulic support,
• dismount the connection of the
drawbar (1) with the lower frame
(7) by unscrewing the bolts (8) and
pulling the pins (3) out of the spring
(6) fixing sleeve (5),
