FIELD: agricultural engineering, in particular, construction of mounted machines requiring frequent and quick detachment under increased vibration and impact load conditions. SUBSTANCE: tractor 1 is connected through tie-rods 3-5 of hitch system to brackets 9,10,11 of frame suspension of mounted machine 2. Each bracket has row of parallel openings for receiving pins of readily detachable connection. Each pin is formed as rod with head at one end. U-shaped handle is fastened with its one end to pin head. Retainer is fixed on rod shank. Rod stop positioned in one opening of each bracket is made in the form of compression spring whose one end is positioned in available sleeve and other end is attached within available cap, which is joined to other end of handle, when rod is blocked by stop. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 3 cl, 4 dwg
