Rear outlets of the outer hydraulic circuit
In a tractor version that is not equipped with front outlets
or a front three-point hitch, the rear outlets are terminated
by pressure quick couplings 1 to 6.
The quick coupling marked 0 is directly connected to the
transmission compartment and is intended for return oil
from external hydraulic appliances (especially rotating
hydro engines).
In the tractors equipped with front outlets, the quick couplers 5 and 6 are not mounted on the
rear panel.
Front outlets of the outer hydraulic circuit
On request, the tractor can be equipped with external
hydraulic circuit outlets located in the front.
The quick couplings (1) and (2) are the pressure
couplings, the quick coupling (0) is directly connected to
the space of the axle final drive housing and is designed
so that the return oil can flow back from the external
hydraulic appliances.
The quick couplings sockets with the 12.5 mm inside
diameter comply with the international ISO
recommendations.
If the tractor is equipped with front outlets of the outer hydraulic circuit, the lever (F)(5)(N)(6) is
used for their control.
If the tractor is equipped with a three-point hitch, the (F)(3)(N)(4) lever is used for its control.
Quick couplers must not be connected at the time of three-point hitch usage connected because they
are pressurized together like front three-point hitch!
After terminating the work with a front three-point hitch for further usage of the section with quick
couplers 3 and 4 with the connection of three-point hitch, it is necessary to lift the arms of the front
three-point hitch to transporting position and the lever of the cock of the front three-point hitch in the
'closed' position.
