2270 r/min (max 55 l/min).

The hydraulic circuit controls:

--- steering system (prioritised)

--- linkage hydraulics

--- auxiliary hydraulics

--- trailer brake valve (extra equipment)

--- four wheel drive, through the pressure relief valve

--- differential lock, through the pressure relief valve

C7.1. Hydraulic lifts

C 7.1.1. Hydraulic three---point linkage

unit

The hydraulic lift has position control, lowering speed

control and draft control. Impulses for draft control are

obtained through the top link. The sensitivity can be

regulated by altering the fastening point of the top link.

C 7.1.2. Electro hydraulic three---point

linkage

Notinopencabmodels.

AC8

When an electro---hydraulic Autocontrol B (ACB) is fitted,

the control levers are replaced with knobs and switches.

Pre---programmed/programed functions:

--- Draft control/position control combining ratio plus sensi-

tivity on the regulator, the sensitivity adjustment is auto-

matic.

--- Lowering speed (independent of load)

--- Tr a n s p o r t h e i g h t

--- Drive balance control system

C 7.1.3. Front linkage (optional equipment)

The tractor has two valves for auxiliary hydraulics as

standard. One valve can be changed to single --- or

double acting. Two additional valves can be fitted as an

optional accessory, also one valve can be fitted for the

trailer braking system. Single---lever control is used for

these standard valves.

Four quick---action couplings are mounted as standard at

the rear of the tractor. Provision has also been made for

the mounting of four extra couplings and brake valve
