The rear hitch linkage of HL-2 type is made in accordance with GOST 10677 (corresponds
to Cat. 2 as per ISO 730/1).
The hitch linkage
, as mentioned above, consists of three rods (upper and two lower)
connected by joints with the front ends to the tractor and the rear end with free joints to connect
with connecting fingers of the unitized machines. It is designed for connection to the tractor of
machines in the rear position, transmit tractive force during work and adjust their position during
operation or movement in the transport position.
The hitch linkage provides unitizing of the following types of machines and tools:
- mounted with three-point hitch (upper and lower rods);
- semi-mounted (lower rods);
- semi-trailed with a crossbeam on the suspension axle (lower rods) as described in 6.8.3
TC-1 (crossbeam) of this manual.
To prevent swinging of the attached machines, the restrictive external strainers with
adjustable length serve (see below).
To ensure the required position of the machine, the following adjustments of the rear HL in
the vertical and horizontal planes with the upper rod, braces and strainers are provided:
Changing upper rod length.
Made to ensure the same depth (equalizing the depth of travel of the working tools arranged
one after another along the tractor course); if the frame of a mounted plow is tilted forward along
the tractor course and the front bottom plows deeper than the rear, lengthen the upper rod and
shorten it if the front bottom plows with a lesser depth than the rear.
Changing brace length.
Made to bring the machine to the horizontal plane in order to ensure a uniform tillage depth
by the working tools of the mounted machine by coverage;
Attention:
Changing the length of the left (screw) brace of the HL of 640 mm (standard
tires) is not recommended. The length is adjusted usually for the right (gear) brace. When using a
cross-beam on the suspension axle and working with reversible plows, the brace lengths must be
the same.
