Max torque (ECE): 235 Nm
Max torque rpm: 1600 min-1
TRANSMISSION
Drive: permanent 4WD.
Available speeds: n.4 speed forward and reverse gear
Transmission ratios:
at differential 1:2,82 at hubs 1:6 total at rear axle1:16,91
Reduction gear-transfer case ratios: 1:4,06 e 1:1,43

BRAKE (complying with directives 76/432/CEE and 96/63/CE)
Service brake: acts on rear axle. Oil-immersed discs type, mounted
integrated with axle, close to the differential box. A self-adjusting
and controlled-piston return device automatically compensates wear of
all the involved elements and ensures the brake pedal maintains a
constant stroke for the machine service life.
Parking brake: hand-operated mechanical, discs type, integrated with the service brake.
REFILL CAPACITIES
fuel tank: 90 litres
hydraulic oil tank: 90 litres
hydraulic oil total filling: 125 litres
coolant: 7 litres antifreeze + 7 litres H2O
VALVES AND SAFETY DEVICES
Locking valves installed on all rear stabilizers cylinders, independently controlled for full machine stability.
Locking valve front movements.
Locking valves for lifting, dumping, booming cylinders.
Rear excavator: rotating and lifting locking device, balancing locking device
Front bucket teeth cover blade
Angle transducer for the bucket and forks horizontally
Angle transducer to avoid the possible overload.
HYDRAULIC SYSTEM
Hydraulic gear pump:
no. 1 (double body with hydrostatic pump): max capacity 95 litres/min
Max working pressure: 200 bar
ELECTRIC SYSTEM
Voltage rating: 12V
Earth terminal: negative
Batteries: no. 1
Battery capacity: 100 Ah
Alternator: 12V 60 A
Illumination devices and luminous signalling: in conformity with
road traffic laws. Work lights and blinking light for operator
machines. Safety battery switch. Acoustic howler for the reserve motion.
STEERING GEAR
Danfoss steering unit, hydrostatic type, with load sensing
signal which regulates flow coming from the priority vale to power
steering and connected to the reservoir for free flow when the steering
unit is in neutral position. The hydraulic power steering acts on two
double-acting cylinders, in protected position, which causes the
relevant front and back chassis to turn around the hinge pin.
ARM AND CHASSIS
The vehicle bearing frame consists in a front and rear chassis
connected by a two-axles ball-joint, vertical for the steering angle
(+/- 40°) and horizontal for the oscillation (+/- 12°). For special
applications, the oscillation of front and rear chassis can be locked
by two hydraulic pistons, inside the rear chassis, (DBS
system-optional), through a single electric control. Both the front and
the rear chassis are arranged in advance to accommodate interchangeable
attachments. Arm structure made of special steel. The rear un-coupling
is provided with adjustment sliding devices on the stabilizers, to
eliminate the oscillation and to reduce the wear and tear.
Its possible to lock the backhoe in different positions: diagonally
on left or on right, centrally and at 45° on left or on right.
CAB
Safety cab: ROPS and FOPS (according to 86/295/CEE and 86/296/CEE).
