Hydraulic system
The system consists of the inner and outer circuit.
The source of pressurized oil is a gear pump.
Oil is drawn from the common filling of the gearbox and final drive housing.
Indication of low oil temperature
FHD18N062
If the temperature of the gear oil is lower than 20°C, it is not recommended to use the outer
circuits of hydraulics.
When handling the controllers of the outer hydraulic circuits at the temperature of the gear oil lower than 20°
C, the operational protection signal lamp on the instrument panel is activated and an error message is
displayed in the display
(1) - defect code 520267
(2) - defect specification FMI 31
Should this be the case, interrupt handling the controllers of the outer hydraulic circuits. After several
seconds the display is switched to the preset main screen. Do not use the outer hydraulic circuits until the
temperature of the gear oil increases above 20°C.
Hydraulic pump
The hydraulic pump is not switchable off. If the engine is
running, the pump is in operation.
Standard design of the tractor - the pressure exerted in
the hydraulic system by the hydraulic pump is limited by
the safety valve to 20.5 MPa.
Tractor with auxiliary switch for front hydraulic
circuits - The pressure exerted in the hydraulic system by
the hydraulic pump is limited by a safety valve to 23.5
MPa.
