C. General description

steering movement is transmitted from the steering wheel

by oil under pressure either to the front axle or to the

centre pivot. This makes steering particularly easy.
If the oil pressure in the steering system should fail for any

reason, steering is still possible by manual power, and the

steering valve will act as a pump.
The tractor hydraulic system has a priority valve, which

ensures that there is always sufficient oil for the steering

system.

C 7.

Hydraulic system

T1LS C9

The tractors hydraulic system has both a low pressure

circuit and a high pressure circuit.

The gear pump of

the low pressure circuit

controls:

--- steering system (prioritized)

---quick---shift gear

---powered front axle, disengaging

--- power take---off

--- differential lock

---shuttle lever

--- parking brake

--- moving of the range gear

--- trailer brake valve (extra equipment)

The high pressure circuit =

the displacement pump of

the working hydraulic circuit controls:

--- linkage hydraulics

--- auxiliary hydraulics

Due to the LS---system of the displacement pump only the

necessary volume of the oil is supplied for the working

hydraulics corresponding to the pressure load.
The system has also a separate lubricating pump, which

supplies oil for:

--- the ejection of the high pressure circuit activating the

suction of the displacement pump (if necessary)

--- the lubrication of transmission and PTO

The max. capacity of the high pressure circuit pump:

115 l/min, at 2200 r/min.
The tractor has as standard an electro---hydraulic linkage.

The linkage is controlled through the electric

potentiometers and switches.
Pre---programmed functions:

--- draft control/position control combining ratio plus

sensitivity on the regulator, the sensitivity adjustment is

automatic.

--- lowering speed (independent of load)

--- transport height

--- drive balance control system, connecting of the driving

speed can be adjusted

--- slip control

Max. lifting capacity of the hydraulic lift is 8100 kg.
The front linkage is available as extra equipment.
