A semi-mounted coupling of a tractor comprises a power driving bar and side carrier bars, hingedly connected therewith, with implements-machines, mounted thereon, supporting wheels. The side carrier bars are made of two parts, connected therebetween by a parallelogram mechanism, which is fixed by a spacing control rod in such a position that the side implements-machines and working elements thereof are arranged on the geometrical axis passing through the kinematic centre of the tractor. |
