Rear axle

Rear axle with bevel gear pair and epicyclical rear final
drives.

Interflange: .........................................................1640mm

Bevel gear pair: ........................................11/51= 4,6364

Rear final drives: .........................................................6,6

Total reduction ratio: .........................................30,60024

Front and Rear Axle ratio

Differential lock

Rear differential lock with electro-hydraulic control and
hydraulic engagement.

In all models, the diff lock is disengaged by means of the
brake pedals.

Front and rear differential locking takes place at the same
time  by  means  of  the  Twin-Lock  system  in  four-wheel
drive tractors.

CAUTION: The technical specifications given here are 
only of a general kind. For technical specifications of 
each market, please refer to the information material 
supplied by your Dealer.

Transmission

Xtrashift

4-speed gearbox for 3 ranges (Low - Normal - Fast) with
electro-hydraulic  gearbox  with  three  Powershift  ranges
under  load  (available  only  forward)  and  with  electro-
hydraulic reverse shuttle.
It gives a total of 36 FWD + 12 REV speeds.
Park-Lock (on request)

4-speed gearbox for 4 ranges (Low - Normal - Fast and
Creeper on request) with electro-hydraulic gearbox with
three Powershift ranges under load (available only for-
ward) and with electro-hydraulic reverse shuttle.

It gives a total of 48 FWD + 16 REV speeds.

Park-Lock (on request)

X60.20-X60.30-X60.40 Xtrashift Gearbox

On tractors with mechanically regulated engine, the Over-
drive is automatically selected on reaching a 40 kph speed.

X60.50 - Xtrashift Gearbox 40 kph ECO

The transmission controller limits max. speed to 40 kph at
1900 engine RPM, thus obtaining a significant reduction in
fuel consumption when transporting and driving on road.

All models - Potentiometer to regulate the engage-
ment speed of electro-hydraulic clutches.

For speed charts, see the Operation section, Gear-
box.

Power take off

 [4.2.d]

Independent mode

PTO  engaged  through  a  hydraulic  clutch  with  electro-
hydraulic control by means of a button in the cab.
Engagement is modulated by a hydraulic accumulator.
The PTO driveline is stopped through an electro-hydrauli-
cally controlled brake by means of the same switch used
to control the PTO itself.

Available in the following configurations:
Two speeds:
1st type: 540/540ECO RPM
2nd type: 540/1000 RPM

Three-speed (on request):
3rd type: 540/540ECO/1000 RPM

PTO rated speed - Engine rated speeds for any configu-
rations.

Different PTO output shafts are available, in compliance
with A.S.A.E. standards.

- 1 3/8” (34.9 mm) diameter shaft with 6 splines (standard

assembly).

- 1 3/8” (34.9 mm) diameter shaft with 21 splines (standard

assembly).

Synchronized ground drive PTO mode (optional)

Rotation speed in synchronized mode (PTO driveline turns
per rear wheel turn):

• 10.200RPM with PTO at 540 RPM

• 14.2384 RPM with PTO at 540E RPM

• 19.1583 RPM with PTO at 1000 RPM

Engagement and selection of PTO operating mode by a
selector lever on the left side of the seat.

Brakes

Rear brakes

Multidisc oil-cooled brakes mounted on rear differential
half shafts.

Number of friction discs: .........................12 (6 per side).

Friction material ...................................... .resin-graphite.

Hydraulic  control  by  means  of  the  two  pedals  on  the
driver’s right: the two pedals can be coupled together by
a locking device to provide simultaneous braking action
on both sides.
Breaking Booster System.

Parking brake controlled by an independent hand lever
and linkage acting directly on the main brakes.

Hydraulic trailer brake mounted on request.

Compressed air trailer brake mounted on request.

Front brakes for 4WD tractors

Multidisc oil-cooled brakes mounted on front differential
half shafts.

Number of friction discs:

All models................................... ...............4 (2 per side).
Friction material................................. ........resin-graphite.

IBS-Integral  Braking  System  hydraulic  control  ensuring
simultaneous  braking  along  with  the  rear  brakes  when
the brake pedals are coupled together by means of the
relative locking device.

4WD front axle

Front  axle  in  spheroidal  cast  iron  pivoting  around  two
central supports.

Electro-hydraulic  front  drive  engagement  by  means  of
hydraulic clutch.
Spring-On/Pressure-Off type.

Propeller shaft without universal couplings installed along
the longitudinal axis of the tractor.

Transmission  through  central  differential  and  epicyclic
final drives in the wheel hubs.

Max. steering angle ....................................................55°

Front axle with oil-cooled front brakes. The front brakes
are  the  oil-cooled  multi-disc  type  mounted  on  the  live
axles of the front differential: 4 discs (2 for each live axle).

lock mounted as standard supply. Engagement occurs at
the same time the rear differential is engaged. The diffe-
rential lock is disengaged by means of the brake pedals.
