shaft 2 that is installed in bracket 1, which is mounted on top face of rear axle. The levers
3 are connected with draft links 7 trough drawbars 5.
The draft links are mounted by front pivots in bracket 11 (right and left) on special
sensors of draft control 13. The brackets 11 are fixed on tubes and side faces of rear axle.
On draft links 7 there are eyelets 8, on which are mounted drawbars 9 by its forked part
