The system which connects the series of plough bodies is built on the principle of double external bar. So it becomes possible even during the work of the plough to change simultaneously the working width of the plough body series (especially its front part).

The double bar system makes it possible to distribute the forces affecting the system and it helps to prolong the life time of the plough. The whole structure was designed on the external part of the casting, on one hand, for the easier maintenance of the connecting points, on the other hand, for easier possibility to assemble new plough bodies.
