[. . . ] Moving the control lever of outer circuit in this direction ensures that pressure oil in quick-coupler "1" causes lifting of the frames to vertical (transport) position. Quick-coupler "2" is connected with return line. Tractor equipped with selective control valve When working with agricultural machines that are combined from more parts (combinators, skids, and harrows), at which side frames, folded at transport to vertical position by independent hydraulic cylinders, controlled by outer hydraulic circuit, are hinged to the central frame, it is necessary always to control folding of outer frames by moving the control lever of the selective control valve upwards (rearwards). Then the „lifting“ branches of the cylinders must be connected with quick-couplers "4“ or "6“. Connection of rotary hydraulic motor If a rotary hydraulic motor is connected with hydraulic outer circuit, the return line must be always connected with quick-coupler "0". Connection of reversible hydraulic motor From functional reason, a reversible hydraulic motor must be connected with quickcouplers "1" and "2", possibly always with quick-couplers of one section of the selective control valve. But in this case both lines must be equipped with relief valves which will reliably limit the pressure peaks when stopping the machine. The oil return lines from these valves should be connected with quick-coupler "0". 101 NOTE 102 HITCHES Page Rear three point hitch. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 104 Safety regulations for working with three point hitch . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 104 Attaching of implement to three point hitch . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 105 ∗ Lower link stabilizers . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 106 ∗ Telescopic lower draft links . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 106 Top link . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 107 Selection of top link position. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 107 ∗ Front three point hitch . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 108 Front three point hitch control . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 108 Regulation of lowering and hydraulic lock of front three point hitch. . . . . . . . . . . . . . . . . . . . . . . . . 108 Reduction valve setting . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 109 Attaching of implement. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 109 Driving with agricultural machines attached in front three point hitch. . . . . . . . . . . . . . . . . . . . . . 109 103 HITCHES REAR THREE POINT HITCH Rear three point hitch is intended for attaching of carried or semi-carried agricultural machines and implements with hitch points of category I or II according to ISO regulation.
