3.20 All-purpose drawbar hitch
In basic configuration of “BELARUS – 1822.3/1822 .3/2022.3/2022 .3” tractor the
drawbar hitch of lift type includes a yoke TSU-3V and a yoke TSU-2V. Against order the tractor
may be equipped with a draw bar TSU-1M-01 and a “Python” unit (TSU-2R).
The yoke TSU-3V is intended for operation with two-wheel and four-wheel trailers. It
consists of a towing yoke 4 (figure 3.20.1) with a kingpin 5 and side bars 2. The yoke is se-
cured in a bracket 1 by means of a pin 3 with a key. The yoke position can be changed
up/down by means of moving in the guides of the bracket, and also by way of turning the TSU-
3V round the horizontal axis by 180°.
The yoke TSU-2V is intended for operation with heavy-duty two-wheel and four-wheel
trailers and semi-trailers. It consists of a yoke body 7 and a kingpin 6. The yoke position can
be changed up/down by way of moving it in the slits of the bracket 1. The yoke is secured by
the pin 3 with the key in one of the bracket 1 grooves.
The draw bar TSU-1M-01 is intended for coupling the tractor with agricultural trailed
and semi-trailed machines. It consists of a bracket 18, located at the bottom of the rear axle
body, a link 16 and a kingpin 8 with a splint pin 9. The front end of the link is fixed in the
bracket 18 with a pin 17, and its middle part rests against a crossbar 12. The link is secured
against lateral movements in the crossbar 12 by means of a brace 11. The link 16 can be ad-
justed for the dimension of 400 and 500 mm from the PTO end to the trailer attachment place
by means of re-mounting the pin 17 in the link grooves.
The “Python” unit (TSU-2R) is used for tractor coupling with agricultural semi-trailed
machines and two-wheel trailers. The unit 15 is mounted in the bracket 1 guides and is se-
cured with bolts 14. To attach a trailer it is necessary to take a pin 13 out, put the trailer hitch
iron on the abutment 10 and mount the pin 13 back, it prevents the trailer brace from detach-
ing.
As a rule, the “Python” unit (TSU-2R) is mounted to the places of draw bar installation. Therefore,
before mounting the TSU-2R it is required to dismount the link 16 with the crossbar 12.
