approach the hitch of the transported machine at a low speed with lowered hydraulic
hook which has a latch set into “open” position. In doing so, it is necessary to visually
combine the planes of symmetry of “hook-hitch” coupling units; when the distance be-
tween their connecting elements equals to 0.6
– 1.0 m, leave the cabin and make
sure of coincidence of the hook mouth and the hitch in the vertical plane; if needed,
provide for such coincidence by steering wheel rotation; continue tractor approach
until the hook stops in the hitch, then, operating the hydraulic distributor lever, lift the
linkage in order to introduce the hook mouth into the hitch and lift the hook into the
transportation position to the height of 700 mm;
close the latch and install drawbars;
connect the machine hydraulic system to the tractor hydraulic system;
join the connecting heads of the pneumatic system. Before connecting the tractor
pneumatic system, press the valve of the tractor connecting head and, having opened
the separating valve, blow down the system until condensate is removed. At negative
temperatures, repeat this operation after the completion of work as well;
connect electrical equipment.
If a road train is composed (with semi-trailer and trailer), reconnect the marker lights to the
trailer;
connect safety chains of the vehicle (semi-trailer or trailer) to the connecting links located on
the lifting eyes of lower links of the linkage.
REMEMBER!
Latch and arrestor catch of the hook shall be located in the longitudinal
vertical plane above the hook mouth and locked with splint pin.
Hitch iron
provides connection of the tractor with trailing agricultural machines (implements)
having hitch frames with coupling hitches.
Hitch iron shall be installed into hinge pivots
1 of lower links 2 and 3 of the linkage and
fastened by axle-pins. In doing so, the
length of vertical struts shall be adjusted so
as to have the pins connecting the outer
and internal pipes pass through the lower
hole of the outer pipe and the upper hole of
the inner pipe.
Hitch iron
shall be installed
at the height of 400-500 mm from the
ground surface to the lower plane of the
hitch iron mouth.
