Front outlets of the external hydraulic circuit
Control of the external hydraulic circuit front outlets
Quick-couplings with drip collection
Connecting and disconnecting quick-couplers
When connecting and disconnecting the quick-couplers pay increased attention with regard to
the residual oil that remains in the socket or on the plug of the quick-coupler. For environmental
reasons after every disconnection of quick-couplers this residual oil must be removed with any
textile material.
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.

The front outlets of the external hydraulic circuit are
controlled by a lever (a) which has four positions:
N - Neutral position. Quick coupler drives (1) and (2) are
closed and oil in the hydraulic appliance connected is
blocked. Lever (a) is locked in this position.
1 - Pressure in quick coupler (1). Quick coupler (2) is
connected with the drain. Lever (a) is locked in this
position. In case pressure exceeds 16.5 MPa when
connected to quick coupler (1), lever (a) automatically
returns to (N) position - 'kick-out' function.
2 - Pressure in quick coupler (2). Quick coupler (1) is
connected with the drain. Lever (a) is locked in this
position. In case pressure exceeds 16.5 MPa when
connected to quick coupler (2), lever (a) automatically
returns to (N) position - 'kick-out' function.
P - Floating position. Both quick couplers (1) and (2) are
connected with the drain and oil is free to flow in both
directions. Lever (a) is locked in this position.
PGPPN165
On request, dripping system for holding leakage oil can be
installed. Regularly check whether the tank is not full;
dispose of the oil in an environment-friendly way.
