Rear outlets of the outer hydraulic circuit
In the tractor version that is not equipped with the front
outlets or the front three-point hitch and that is equipped
with:
a - a three-section distributor the rear outlets are
terminated with pressure quick-couplers '1' to '6'.
b - a two-section distributor the rear outlets are terminated
with pressure quick-couplers '1' to '4'.
The third quick-coupler marked '0' is directly connected to
the final drive housing and is designed for return oil from
external hydraulic implements (e.g. from rotational
hydraulic motors, etc.).
In the tractors equipped with front outlets, the quick couplers 1 and 2 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)(1)(N)(2) 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.
