Engaging differential lock
The purpose of a differential lock is to lock both axles 1:1 so that all four wheels will spin at the same
speed in a low traction situation. Engaging the differential lock creates extreme shear forces in the gear
system that can easily damage the tractor.
Warning: Failure to comply with the following guidelines will result in damage to the tractor.
To avoid damage to the tractor and voided warranty while using the differential lock, the following
guidelines must be adhered to:
l Only use the differential lock in strait-line travel with engine speed 1200-1500 rpm maximum and
no wheel spin. If the wheels are spinning, damage can occur to the differential lock system. That
damage will not be considered a warranty repair.
l Only use the differential lock for extreme situations with low traction such as inclines to prevent
wheel spin.
l The differential lock is equipped with a momentary switch and therefore must be held in the
position in order for the system to be active.
l The differential lock must not be held on for a prolonged period of time.
l Do not attempt to use the differential lock when you have wheel spin.
l For cornering, you must switch off the differential lock.
To engage the differential lock:
Warning: Improper use of the differential lock or its abuse will cause massive damage to the
tractor and void your warranty.
1. Make sure that you are driving in a straight line, and the engine is running below 1500 rpm.
2. Ensure that no wheel spin is present.
3. Press and hold the differential lock momentary switch in the down position (Picture). The alarm
will sound, and the differential lock indicator in the instrument panel and in the LED light in the
differential switch will turn on, notifying the operator that the differential lock has been engaged.
4. If wheel spin occurs, release the differential lock switch immediately. You may engage the
differential lock again as soon as the wheels stop spinning.
Warning: Tampering with alarm system will void your warranty and may be a cause of
injuries and damage to the tractor.
Note: To disengages the differential lock, release the differential lock momentary switch.

ADVICE
It only makes sense to use the im-
plement function* for an implement weight above 200 kg.
76
Page 86
9. Getting ready to work with attachments
Without electrohydraulic implement relief, the attached implement rests with its entire weight on the
ground in floating position. With electrohydraulic implement relief*, it is possible to transfer part of the
attached implement weight to the carrier tractor. This results in the following advantages:
• Improvement of traction
• Better steering and tracking of the tractor
• Less wear and tear, e.g. on the scraping blades of a snowplough
• Lower thrust forces together with reduced fuel consumption
• Improved stability on an incline
Procedure
ADVICE
After 3 seconds without any button being pushed at the display, the input values are saved and the
display will reset.
The display (1) will show the current pressure of the implement relief.
The value S.P.1 always has to be less than the pressure of the lifted attachment without implement relief.
1. Push button (24) on the foil keyboard. LED in button (24) lights up.
2. Push the button (3) "Mode". "S.P.1." appears in the display; the current value flashes after 2 seconds.
3. Use the button (4) to reduce the current value.
4. Use the button (2) to increase the current value.
The smaller the difference between S.P.1 and the lifted attachment device without implement relief, the
less weight is transferred to the carrier tractor.
* Optional equipment
Adjusting control sensitivity (hysteresis)
This procedure provides instructions on how to adjust control sensitivity. Higher value of HYS1
provide smoother implement relief. The smaller the value of HYS1, the more sensitively will the
implement relief work.
To adjust control sensitivity:
The pre-applied gas pressure in the membrane accumulator is 30 bar (psi?)
77
Page 87
9. Getting ready to work with attachments
A relief pressure below 30 bar (lightweight devices) leads to frequent control processes, since the
accumulator cannot act yet.
This control sensitivity sets the characteristics of the implement relief.
1. Push the mode button twice within three seconds. HYS1 appears in the display; the current value
(?) flashes after two seconds.
2. Use the button (name?) to reduce the current ? value.
3. Use the button (name?) to increase the current value.
Note: To switch off implement relief, push the button (24 name?) on the keypad and ensure
that the light in the button turns off.

Page 98
10. Special Options (Additional Functions)
Engaging special drive system (SDS)
This procedure provides instructions on how to engage the special drive system (SDS). SDS is designed
for higher driving comfort and only available in low gear range. When SDS is engaged, the ground
speed is controlled with the throttle pedal and determined by the position of the fine speed adjustment
dial.
Before engaging SDS, ensure the following:
1. Tractor is at a complete stop.
2. High/low cable is set for low gear.
To engage SDS:
1. Set the drive program switch to 2.
2. Set the fine speed adjustment dial to the appropriate ground speed level.
3. If needed, adjust the required engine or PTO shaft speed with the hand throttle (?)
4. Use the throttle pedal to accelerate to the appropriate ground speed.
Engaging dual drive system
This procedure provides instructions on how to engage the dual drive system when the tractor has been
parked for an extended period (several hours) and the outside temperature is below 0°C/32°F. The
purpose of the dual drive system is to remove the hydrostatic system from operation and link the engine
directly to the final drive 1:1. The dual drive system is completely automatic. When the ground speed
exceeds 25 km/h (15.5 mph), the drive mode automatically switches from hydrostatic to mechanical
drive. When the ground speed falls below 25 km/h, the gear automatically switches back to hydrostatic
drive.
The dual drive system works only under the following conditions:
l Gear box is in high gear range.
l Drive program switch is set to 1.
Although the dual drive system is optional, it offers the following significant benefits:
l significant reduction of wear and tear of the hydrostatic system
l significant increase of the service life of hydraulic oil
l 40% increase in fuel efficiency
l reduced noise level
l higher maximum ground speed
l enhanced overall durability of the driving system
89
