Connecting machines and tools to External hydraulic circuit
Connecting a double acting cylinder
A double acting cylinder must always be connected to quick couplers of one section.
Connecting machinery and tools assembled from more parts
When working with agriculture machinery which is assembled from more parts (combinators, scrubbers, or
harrows) where the edge frame is hinged to the central frame because it is diagonally folded during transport
by independent hydraulic cylinders which are controlled by outer hydraulic circuit of the tractor, it is
recommended to connect the lifting arms of the cylinders to quick couplers (3) and (5) which are equipped
with a one-way valve.
Connecting rotary hydraulic engine
If a hydraulic engine is connected to outer hydraulic drive, it is always necessary to connect its returnable
arm to quick coupler (0). Filling (pressure) arm can be connected to quick couplers (1) or (2), where the
hydraulic engine is protected by the 'kick-out' function from overload. This function stops the hydraulic engine
if pressure in the filling arm exceeds 17 MPa.
Connecting reverse rotary hydraulic engine
Due to its function, reverse rotary hydraulic engine must be connected to quick couplers of one section. It is
recommended to use quick couplers (1) and (2), where the hydraulic engine is protected by the 'kick-out'
function from overload. This function stops the hydraulic engine if pressure in the filling arm exceeds 17
MPa. If the hydraulic engine is connected to quick couplers of different sections, both arms must be
equipped with safety valves which can be relied on to restrict high pressure peaks during run-out. Connect
the safety valves drain to quick coupler (0).
Connecting external hydraulic distributor
It is recommend to connect external hydraulic distributor to quick couplers (4) or (6). Control levers (b) and
(c) are mechanically locked in these positions without hydraulic lock.
Auxiliary machines using oil filling of external hydraulic circuit must be filled with the same
kind of oil, which is recommended for gear system of the tractor! Quick-couplers sockets of an
auxiliary machine need to be properly cleaned before connecting.
Front outlets of the external 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.
