Upper link and crossbeam
The length of the upper link (4) is adjust-
able within 500...740 mm.
The length of right adjustable crossbeam
(3) can be changed within:
• 580...665 mm for RLL with hydraulic lift.
The adjustment of the arm length is car-
ried out through the turning of the handle
(2). When delivering to the customer the
length of the right arm is adjusted at the
standard value 640 mm (RLL with hydrau-
lic lift).
The length arm (1) (non-adjustable) is also
adjusted at the standard value 640 mm
(b), when delivering to the customer.
IMPORTANT! Adjust the position of the
machine by means of the right cross-
beam (3).
To follow the relief of the field area to be
treated when working with wide-cut ma-
chines and to avoid damage of the cross-
beams, connect crossbeams (1) with
lower links (2) through the slots (indicated
by an arrow).
IMPORTANT! The slots of the cross-
beam fork shall be behind the hole to
avoid the damage of the crossbeam.
Depending on tilling depth and nature of
soil bring the upper link (4) in one of two
positions:
• I — light soils and small tilling depth in
the mode of draft control;
• II — heavy soils and big tilling depth in
the mode of draft control
During the hauling operations bring the
link (4) in position III.
