Hydraulic distributor of the outer hydraulic circuit
The outer circuit of the tractor hydraulics is controlled by the distributor with four-position sections. The
control levers of the sections are located in the cabin on the mudguard of the right rear wheel.
Three-section (three control levers) or two-section (two control levers) distributor can be mounted on the
tractor.
The numbers on the label of the control levers correspond to the numbers of the quick couplers.
The control levers are locked in the rear position at maximum oil flow rate into the quick couplers:
2 or 6 in the three-section distributor
2 in the two-section distributor
After overcoming the increased resistance, the locked lever can be returned into the position (N).
The quick couplers 2 and 4 in the two-section distributor or 2, 4 and 6 in the three-section distributor are
additionally equipped with the return valve ??? use for the connection of the working branch of the machine
with the increased requirement for tightness ??? minimum drop of the tools, e.g. during transport.
