Tractors equipped with front end loade
Zetor Tractors in standard design are designed for utilization in agriculture and are not designed for special
purposes.
Tractors designed for operation within the European Union must be equipp ed, in case of using front end
loader, with a protective structure (FOPS - Falling Object Protective Structure) protecting drivers from
potential falling objects.
It is necessary to observe applicable local valid regulations in countries which are not part of the European
Union.
Two types of cab roofs are mounted to Zetor tractors.
1. Standard cab roof
2. Cab roof designed for tractors equipped with front end loader meeting the OECD code 10 (FOPS)
conditions.
Tractors ZETOR supplied already from production with front end loader are equipped with cab roof according
to point 2.
From safety reasons, series ZETOR tractors supplied without front end loader with standard roof pursuant to
point 1 must not be equipped or used with front end loader.
In case of additional front end loader assembly, it is necessary to equip tra ctor with cab roof pursuant to point
2.
Only front end loaders approved by ZETOR TRACTORS may be mounted to ZETOR tractor.
dditional assembly of front end loader approved by ZETOR TRACTORS can be done only by
authorized ZETOR service.
It is forbidden to use front end loaders unapproved of by ZETOR TRACTORS.
Not observing this instruction may cause serious accidents.

Principles for operating tractors equipped with front end loade
Carefully study operation manual supplied by the manufacturer of front end loader.
In case of discord of Principles for operating tractors equipped with front end loader and operation
manual for front end loader, which was supplied b
the manufacturer of front end loader, the wording
listed in operation manual supplied by the manufacturer of front end loader shall apply.
z The use of front end loader for transporting material at places accessible to the public is forbidden.
z The use of front end loader for transporting material in places inaccessible to the public is possible
only in a limited way. In such case, instructions in user's manual supplied by the loader manufacturer
must be observed.
z Observe local valid regulations at all times.
z A strict ban on transportation and lifting of people by means of loader is in effect.
z No matter whether the front end loader is loaded or empty, no-one may stand in front of the loader if it
is in lifted position. When driving with a lifted loader, there is a risk of load transported by front end
loader falling (there is a risk of disrupting the balance of the tractor).
z Never leave the tractor standing with the loader in lifted position.
z If it is necessary to open the bonnet of the engine at intervention, disconnect the front end loader first
or secure hydraulic rollers of front end loader by metallic props designed for this purpose.
z Hydraulic circuit of the front end loader is designed in such a way to endure the maximum operation
pressure of 20 MPa (200 bar). Do not do any changes on couplers of hydraulic circuit hoses.
z Any front end loader ZETOR mounting without observing the recommendation of ZETOR TRACTORS
valid to the day of pur-chase revokes the validity of guarantee for the whole of supply.
z The loader may be used, maintained and repa ired only by people who perfectly know the machine
and who are informed about potential risks.
z When driving on roads do not transport any material on the front end loader.
z It is necessary to observe special instructions related to accidents prevention an d general rules
related to technical safety, la-bour medicine, labour hygiene and regulation defining operation on
roads.
z The manufacturer does not bear any responsibility for any potential damage incurred as a result of
changes conducted on the loader without their consent.
z Do not ever adjust the front end loader by yourselves and do not use the adjusted front end loader
without prior ZETOR´s ap-proval. The loader may become dangerous as a result of not observing
these instructions. ZETOR TRACTORS shall not be held responsible in case of any damage or injury.
z Use front end loader without additional weights on the tractor (danger of mutual contact). The load of
front and rear drive axle must not exceed the maximum permitted load listed in the manual. The use
of front end loader requires mounting of counter weight in the rear part of the tractor.
z Each working tool was reconstructed for the purpose of specific usage and has its own tolerance of
resistance and tightness.
z It is forbidden to use front end loader for cultivating soil and stubbing. Such work needs to be done
with a special tool, front end loader is not designed for doing this.
z Using controls which would set the loader into motion without driver holding the gear shifting lever is
strictly forbidden and re-sults in installation not meeting the prescribed standard.
z To penetrate the loaded material, better use the kinetic energy of the tractor rather than pressing force
which causes higher strain of both the loader and the tractor.
z Do not overload hydraulic parts if the load is too heavy or pistons are in end positions.
z Control the loader exclusively from driver's seat, if you are sitting on driver's seat.
z Do not leave the seat if you have not blocked any movement of controls.
z No people can be present in the working zone of the loader.
z When working with a lifted loader, mind electric and external cables etc.
z Loader/tractor set needs to be parked on a horizontal and solid base, the arms of the lifting device
must be set in the lower position
You will find more information in user's manual to front end loader.
Important notification: Work always safely and with consideration.
Zetor tractors used for work in the woods
SAFETY INSTRUCTIONS FOR USERS
21
Standard tractors Zetor do not provide sufficient protection for operation in forest terrain as, for example,
protection against a fal-ling tree or branch on a cab or penetration of objects to a cab.
If Zetor tractor is utilized for forest work, a tractor operated within the European Union must be protected
against these risks.
It is necessary to observe applicable local valid regulations in countries which are not part of the European
Union.
To ensure this protection, it is advisable to conduct assembly of a specific protective structure, like for
example FOPS / OPS (Fal-ling Object Protective Structure / Operator Protective Structure), tested according
to standards for forest machines.
Only forest superstructures approved by ZETOR TRACTORS can be mounted to ZETOR
tractors.
In case of additional assembly of further tractor equipment for working in the woods, full responsibility is
borne by the supplier and manufacturer of the protective structure that all the safety regulations (e.g: OPS /
FOPS), all the conditions of homologation (e.g. the area of driver's view, lighting, para meters, permissible
weight etc.) are met, same as for the provision of due assembly of pro-tective equipment. The
supplier/manufacturer of protective construction is also obliged to conduct all the necessary validation
(approval) steps required by the legislature of the country in which the tractor is operated.

Air circulation in cabin control (D)
a - Surrounding (outside) air is sucked in through filters to
cabin - sucking the air from cabin is closed.
b - Air is sucked in from the space of the cabin and again
blown off to the cabin (inner air recirculation for fast
adjustment of temperature in the cabin).
The intake of air from the outside of the cabin is
completely locked and there is no surplus pressure in
the cabin which would prevent pervasion of unfiltered
air to the cabin! Do not use this position of the control
with work of the tractor!
Proper function of the heating and air-condition system
It is necessary to create surplus pressure in the cabin for
proper function of the heating or air-condition. We
therefore recommend you to close all the windows and
doors and tilting cover of the cabin.

Operation of heating or ai
-condition with tractor´s work
With engaged inner recirculation of air is the inflow of
fresh air closed and there is foul air in the space of the
cabin by operator. This state can cause the fee lin g of
fatigue and there can also be penetration of dust to the
cabin because of the loss of surplus pressure.
Note: Set the control (D) according to individual
requirements on temperature to the position between (a)
and (b) so that the ventilator sucks the air from the outside
of the cabin through filters, when working.
When spraying pesticides and using the
heating filter with active carbon, the recirculation
controller should be in position 'air is drawn into from
the outside' and the fan controller should be in the
osition 'fan maximum work' to create overpressure
in the cabin.
Immediately after cooling the cabin
Immediately after cooling the cabin and lowering the inner
temperature on the required values, we recommend the
following:
- Switch over the control of air circulation (D) from position
(b - air re-circulation) to position (a - outer air suction)
- Do the continuous regulation of the air temperature with
air condition on by opening the heating valve (A). The air
entering the cabin from expiration is not so intensively
dried with this setting.
- Continuous temperature control with air-condition on can
be also done by lowering the output of ventilator by
switching the control (B) to position 1 or 2.

To ensure quick defrosting of the front windshield direct
the central heating outlets (1) under the angle of approx.

under the angle of approx. 45° to the cab corners.
After defrosting of the fron t windshield direct the side
outlets to the side glasses of the doors as necessary and
gradually defrost them. After defrosting direct the outlets in
such a way that the air should not be blown directly to the
driver, but down to the driver's legs.
*Air filter with active carbon
F13BN011
F13BN015
Active carbon filters are installed in the placed of standard dust filter and the replacement is done in the
same way as with standard filters. Filter must be inserted with the white side to the grid. Assembly
instructions are found in the chapter 'Maintenance instructions'.
Filter is used only when spraying pesticides, then it must be replaced back by a paper filter because the
flying dust would clog the carbon filter very fast.
The recirculation control must be in the position 'air is sucked from the outside'.
Ventilator control must be in the position 'maximum ventilator run'.
WARNING: filter does not provide full protection against toxic substances
- Wear protective gloves when manipulating with the filter.
- Do not clean the filter and do not blow through with compressed air.
DANGER: Replace the active carbon filter every 200 hours or 36 months (date of production is
given on the filter). If you happen to smell pesticides in the cabin, replace the filter immediately and
have the sealing of the cabin checked. Used filters must be damaged in specialized collection
centres.
When spraying pesticides and using heating filters with active carbon, the recirculation
control must be in the position of 'air sucked from the outside' and the ventilator control 'maximum
ventilator run' for creating surplus pressure in the cabin.
When spraying pesticides, increased care should be taken when entering or exiting the tractor
because of possible contamination of the working area. Follow the safety instructions for handling
esticides according to the valid legislation of the country where the tractor is used, type of the
hazardous substance, instructions of the manufacturer of the hazardous substance and
manufacturer of the carried or towed sprinkler.

NOTES
68
The tractor is equipped with the engine fulfilling emission limits STAGE IV and TIER 4f. The compliance with
SYSTEM OF ADDITIONAL TREATMENT OF EXHAUST GASES
69
the emission limit is achieved, among others, by the combination of two systems of treatment of exhaust
gases:
a - Diesel Particulate Filter (DPF) designed for purification of exhaust gases. In the diesel particulate filter,
solid particles (carbon black) formed during incomplete combustion of diesel fuel are gathered and then
burnt. The oxidation catalyst (DOC) is a part of the DPF unit as well.
b - SCR - the SCR abbreviation stands for system for cleaning of exhaust gases of diesel engines using the
selective catalytic reduction decreasing the amount of NOx in the exhaust gases. At the same time, the
reduction agent injected into the exhaust system reacts in SCR catalyst with NOx emissions contained in
exhaust gases which are reduced to nitrogen (N2) and water (H2O). The control of the injected amount of
urea is performed using the control unit itself in connection with the control unit of the engine.
To ensure proper functioning of the system, several its parts are monitored so to meet the
required emission limits:
- The level and quality of urea injected in the catalyst SCR.
- The amount of NOx in exhaust gases and temperature in the system.
- Detection of an illegal intervention and any handling to put the system out of order.

Conditions for DPF operatio
n
SYSTEM OF ADDITIONAL TREATMENT OF EXHAUST GASES
70
When the tractor is operated, the diesel particulate filter is fouled with solid particles during the fuel
combustion while the engine is running. The regeneration of the diesel particulate filter in case of increased
temperature of exhaust gases is performed at higher engine load. The regeneration of the DPF filter is
supported by evaporation of diesel fuel into the piping of the exhaust system through the oxidation catalyst.
Indication of operation of the full diesel particulate filter is indicated by the pair of signal lamps
(green and orange/red) on the instrument panel. Activation of the green signal lamp indicates that there are
optimum conditions for regeneration of the diesel particulate filter. Flashing of the green signal lamp indicates
that regeneration of the diesel particulate filter is being performed. Defects of the system of the diesel
particulate filter when the engine is running are indicated by switching the red signal lamp on the instrument
panel, corresponding error message on the display together with an acoustic signal.
A short-term activation of the red signal lamp without the subsequent acoustic signal does not
mean indication of the defect.
During operation of the tractor with a low engine load, e.g. during a long-term operation at idling, the risk that
the diesel particulate filter becomes full is higher. While the engine is running, this state is indicated by
activation of the orange signal lamp of the diesel particulate filter, by the subsequent acoustic signal and by
the corresponding error code on the display of the instrument panel. If this situation occurs, increase the
engine load and continue in your work until the orange signal lamp of the diesel particulate filter is
deactivated and the acoustic signal stops. By increasing the engine load the temperature of exhaust gases is
increased and the solid particles blocking the diesel particulate filter are combusted. The conditions suitable
for regeneration of the filter of solid particles DPF while the engine is running are indicated by activation of
the green signal lamp on the instrument panel.
The increased engine load means the operation of the tractor at higher revolutions of the
engine with attached implements, consumption of the power through the take-off shaft or outer
hydraulic circuit; increasing the engine speed of the standing tractor is not sufficient.
The time necessary to decrease the DPF resistance depends on the engine load and how
much the DPF filter is full.
There are high temperatures achieved during regeneration of the DPF filter. Great care should
be taken when the tractor is operated in a flammable environment!
Do not stop the engine during regeneration of DPF (the green signal lamp flashes) - there is
a risk of damage of the system of treatment of exhaust gases. Do not stop the engine immediately
after regeneration of DPF filter.Leave the engine idling at low revolutions until sufficient decrease of
temperature of the system of treatment of exhaust gases is achieved!

The used reagent is a mixture of 32.5% solution of synthetic urea and demineralized water. It is used as
a reducing agent NOx for additional treatment of exhaust gases by SCR (selective catalytic reduction) of
motor vehicles with diesel engines.
The product is labelled as Urea or AUS 32 (AUS: Aqueous Urea Solution) and complies with the standard
ISO 22241-1 Reducing agents NOX AUS 32.
The urea solution AUS 32 is known in USA and North America as Diesel Exhaust Fluid (DEF).
The lifetime of urea without the loss of the quality is influenced by storage conditions.
It crystallizes at ambient temperature below -11°C and at ambient temperature over +35°C it initiates
hydrolytic reaction which means that a slow decomposition to ammonia and carbon dioxide begins.
It is essential to protect unprotected vessels from direct sunlight.
Barrels must not be stored longer than one year!
Pay attention to the resistance of the used materials and store vessels.
Urea freezes below the temperature of -11°C.
To ensure proper functioning of the SCR system, urea with the concentration of 32.5% must be
used!
Principles for safe handling of urea (AUS 32, DEF)
Contact with skin
- Prolonged or repeated contact may cause skin irritation.
Contact with eyes
- Prolonged or repeated contact may cause eye irritation. Rinse eyes with plenty of water for at least 15
minutes. If irritation persists, visit a physician.
Ingestion
- In case of ingestion of small quantities, toxic effects are not likely. Higher amount may cause intestinal or
stomach problems. Do not induce vomiting. Drink half a litre of water or milk. In case of ingestion of a larger
than small quantity, visit a physician.
Fire-fighting measures
- The product has fire extinguishing properties.
Extinguishing means
- If the material got in the fire, use large amount of water for extinguishing.
Accidental release measures
- Minimize contact of the spilled material with the soil so that you do not allow product to reach surface or
underground water courses.
- Soak u
the spilled material with dry soil, sand or other non-flammable material

S15N019
By repeated pressing of button (A) you can switch between individual screens to the screen with the data on
the status how much the DPF filter is full:
1 - percentage filling of DPF with carbon black
The position (1) indicates the percentage filling of DPF filter with carbon black that fills the filter during
combustion of diesel fuel. This carbon black is combusted during regeneration of the filter and ash is formed.
The ash cannot be removed from the diesel particulate filter using a common regeneration. At higher
percentage filling of DPF filter with ash, intervals between DPF regenerations are shortened.
Note: If the information how much the filter is full is not available, ( --- ) is displayed on the display instead of
percentage values.
At higher percentage filling of DPF filter with ash please contact authorized service.
Long-term shutdown of tractor
During a long-term shutdown of the tractor, the urea filling must be drained from the tank.
Before operating the tractor, the urea tank must be filled with a new filling again and the urea filter element
must be replaced and the urea tank must be refilled with fresh material.
The urea filling should not stay in the tank longer than four month and then it should be
replaced.

Gear shifting
The tractors are equipped with a four-speed synchronized
gearbox with two-speed reduction, a three-stage torque
multiplier and reversing.
The four-speed gearbox is controlled with the shifting leve
with buttons for controlling the torque multiplier (2) and
a red button for disengaging travelling clutches (1). The
forward and reverse motion of the tractor is selected with
the reversing lever located on the steering column.
Reversing lever
The reversing lever is used to select the driving direction
of the tractor (forward, reverse).
F - Forward drive (24 speeds)
N - Neutral position
R - Reverse drive (24 speeds)
The reversing gearbox offers 24 reverse speeds that are
approximately as fast as the forward speeds. Therefore,
consider well and select a suitable reverse speed for the
particular character of work.

The principles of appropriate use of tractors
The listed principles for tractor´s operation serve for facilitating the operation and guarantee
corresponding service life of travel clutch!
The description of the system of travel clutches
The tractor is equipped with two individual travel clutches, one for travelling forward and one for travelling
backward.
The selection of the driving direction and also the choice of a specific travel clutch is done by shifting the
reversing lever under the steering wheel from neu tral position to the positio n forward or backward.
The way of controlling the travel clutch by
1 - Reversing lever
2 - Clutch control button on the head of reversing lever
3 - Clutch pedal
The differences in ways of controlling the travel clutch by
1 - Reversing lever
This way of control has automatic start function.
When shifting the reversing lever to neutral position, there is release of travel clutch.
When shifting the reversing lever to the forward or backward position, there is a switch of travel clutch and
subsequent smooth dead start of the tractor in the direction defined by reversing lever.
The speed of switch of travel clutch and the smoothness of dead start is controlled by a controlling
unit on the basis of information saved in calibration and the operators cannot influence it.
Automatic dead start function is sparing to travel clutches than the control of travel clutches
by clutch pedal, therefore use the ways of controlling travel clutch with the function of automatic
dead start for the regular operation of tractor with dead start, gear shifting or the change of the
driving direction.
2 - Clutch control button on the head of gear shifting lever
This way of control has the function of automatic switch of travel clutch.
When pressing the button of clutch control on the head of gear shifting lever there is release of travel clutch.
When releasing the red button of control clutch on the head of gear shifting lever, there is a switch of travel
clutch.
The rate of travel clutch switch is controlled by electronic control unit on the basis of information saved with
calibration and the operator cannot influence it.
3 - Clutch pedal
When depressing the clutch pedal, there is release of travel clutch.
When releasing the clutch pedal, there is a switch of travel clutch.
The speed of travel clutch switch is dependent on the speed of releasin g the clutch pedal.
The clutch pedal does not enable the function of automatic dead start and operators influence the speed and
smoothness of dead start.
Use the clutch pedal only for stopping the tractor in regular operation.
For the need of delicate inching, for example when connecting tools or when manipulating
with the tractor in crammed spaces, when even the reduced gear speeds are not slow enough, use
the clutch pedal for short time.

occurs, fully depress the clutch pedal immediately to
stop or release the clutch pedal to the upper position
and wait until the sound signal goes silent and the
control of gearbox failure. Lower the engine
revolutions under 1 200 revolutions per minute and
then continue working with the tractor. If you do not
do it, 8 seconds later the interrupted acoustic signal
changes to uninterrupted signal.
FH12N047
Dead start of the tractor
If at dead start, engine revolutions are higher than 1400 rpm L gear of multiplier is automatically shifted, not
depending on the switch of multiplier pre-selection on dashboard being on or off.
If the multiplier pre-selection switch on the dashboard is on at dead start, L gear of multiplier is shifted
automatically independent on the number of engine revolutions at dead start (i.e. when the engine
revolutions are lower than 1400 rpm).
A very fast dead start can cause overloading of driving gear, increased fuel consumption,
st
excessive wear of tyres and damage to load. Use dead start on the 1
gear only when driving with
heavy trailer to the slope and in difficult terrain.
Dead start of tractor in regular operation - automatic dead start function
Automatic dead start function is in the shift of reversing lever with engaged applicable gear followed by dead
start without using the clutch pedal or clutch control buttons.
1. Start the engine.
2. Shift appropriate gear for starting the engine.
3. Release the manual brake, if you are standing on a slope, brake the tractor by foot brake.
4. When shifting the reversing lever form neutral to the requested direction of tractor drive (forward or
backward), the tractor starts.
5. When you increase the engine revolutions simultaneously, release the foot brake.
When depressing the clutch pedal, the automatic dead start function is put off from operation.
Dead start of tractor in regular operation - clutch pedal
In regular operation use the clutch pedal only for stopping the tractor. For the need of delicate
inching, e.g. when connecting the tools or when manipulating with tractor in crammed spaces, if
even the reduced gears are not slow enough, use the clutch pedal only for short time.
It is forbidden to control the speed of tractor by partial depression of clutch pedal with engine
revolutions higher than 1200 rpm. Do not use the clutch pedal as a foot rest. There is a risk of limited
service life or failures of travel clutches.

Dead start - using the clutch pedal
1. Start the engine.
2. Depress the clutch pedal.
3. Select road and reduced speeds.
4. Shift an applicable gear for starting the tractor.
5. Shift the reversing lever to the direction requested (forward or backward).
6. Slightly increase the engine revolutions.
7. Prepare the manual brake for unbraking.
8. Release the clutch pedal only to the point of travel engagement and with simultaneous increase of
revolutions continue in a continuous release of the clutch pedal.
9. Fully unbrake the manual brake.
10. Start smoothly and slowly.
Use this way of dead start when you need to inch carefully, for example when connecting tools
etc.
Change the direction of driv e
Change the direction of dr iv e by m ea n s of reversing lever
Change the direction of drive by means of reversing lever is done with travel speed lower than
10km/h. When you attempt to change the direction of drive in speed higher than 10 km/h, acoustic
signal starts (uninterrupted tone) and the tractor engages neutral. The signal switches off after the
shift of reversing lever back to N position, when depressing the clutch pedal or pressing the button
of switching clutch on the head of gear shifting lever. It is also necessary to lower the travel speed of
tractor under 10km/h, shift the reversing lever to neutral position and to repeat the shifting of
requested direction.
Keeping the following instruction s when changing the direction of the drive, contributes to
prolonging service life of travel clutches.
· For changing the direction of the drive of tractor use reversing lever under the steering wheel without using
the clutch pedal.
· For changing the direction of the drive of tractor, select the slowliest gear L with torque multiplier.
· For changing the direction of the drive of tractor, select lower gear with regard for the subsequent dead start
and tractor load.
Changing the direction of drive by means of reversing lever is done at tractor travel speed
lower than 10km/h. When you try to change the direction of drive at the speed of more than 10 km/h,
an acoustic signal starts (uninterrupted tone), the signal switches off after the shift of the lever back
to N position, when depressin
the head of the gear shifting lever.
1. Lower the travel speed of tractor under 10km/h by means of brake pedal.
2. Shift the reversing lever to the requested direction of tractor drive.
3. The tractor stops automatically and travels in the requested direction.
4. Continue in smooth dead start of the tractor with simultaneous incresae of engine revolutions.
Should the tractor speed drop below 10km/h, tractor shift neutral and it is necessary to lower
the travel speed of tractor under 10km/h, shift the reversing lever to neutral position and to repeat
the shifting to the required direction.
When depressing the clutch pedal, the automatic function is put off operation. If the above
mentioned is done subsequently after the attempt to change the direction of drive above 10 km/h, it
is necessary to lower the travelling speed of tractor below this speed. In opposite case, after the
release of clutch pedal the neutral remains shifted.

3. Release the clutch pedal only to the point of travel engagement and with simultaneous increase of engine
revolutions continue in smooth release of the clutch pedal.
4. Start smoothly and slowly.
Gear shifting
- For shifting the gear speeds while travelling use the travel clutch control by a red button of clutch control on
the head of gear shifting lever.
- When shifting gears, press and hold the red button of clutch control on the head of gear shifting lever,
release the gas pedal, throw out the gear, shift an applicable gear speed, release the red button and then
increase the engine revolutions.
- If operation conditions permit, use the function of multiplier preselection.
Gear shifting - Using the clutch pedal
Depress the clutch pedal (clutch disengaged). At the same time release the pedal of foot throttle and shift the
applicable gear speed. Release the clutch pedal smoothly (clutch is being engaged) and at the same time
increase the engine revolutions.
Gear shifting - using the clutch control button on the head of gear shifting lever
Press the clutch control button on the head of gear shifting lever. At the same time release foot throttle pedal
and shift the applicable gear speed. Release the button of clutch control (clutch is being engaged) and at the
same time increase the engine revolutions.
Note: Clutch pedal is always preselected to the use of button of clutch control on the head of gear shifting
lever.
Blocking the automatic dead start function
With some failures of travel clutches system, the function
of automatic dead start is blocked. This situation is
signalized by an inscription displayed on a display. In this
case reversing lever under the steering wheel serves only
for the selection of direction of drive, the button for clutch
control on gear shifting lever does not work. For dead start
of tractor and gear shifting, it is possible to use only clutch
pedal.
If this situation occurs, finish your work and
contact service.

Multiplier preselection switch
PW15N037
The switch of the multiplier pre-selection is located on the board of the instrument panel. Activation of the
switch is indicated with the activated symbol on the switch and the symbol in the instrument panel display.
If the switch of the multiplier pre-selection is switched off, the gears of the multiplier can be shifted on the
gear shift lever.
If the switch of the multiplier pre-selection is switched on, the gears of the multiplier are automatically shifted
dependin
on the engine revolutions according to the pre-stored values.

Automatic multiplier shifting
The system of automatic multiplier shifting is switched by multiplier pre-selection switch. If the multiplier preselection switch is on (control on the switch is lit), the gears of multiplier are shifted automatically depending
on the engine revolutions according to preset values (engine revolutions). The system of automatic multiplier
shifting is not dependent on the engaged speed gear. With engaged multiplier pre-selection switch, it is
possible to turn the engine off and start and the saved values (engine revolutions) do not change. The values
for automatic multiplier shifting are read always when the pre-selection switch is off, with tractor drive wi th
engine revolutions higher than 700 rpm, with travel speed higher than 2 km/h.
When meeting the previous conditions, the system will remember
a - Engine revolutions with last use of L button on gear shifting lever for automatic shifting of multiplier gears
for lowering the travel speed
b - Engine revolutions with last used of H button on gear shifting lever for automatic engagement of gears of
multiplier for increasing the travel speed
The difference between the engine revolutions for a and b must be greater than 250 rpm
Example of use:
We are driving with a tractor with multiplier pre-selection off with multiplier shifted to 2 gear, with engine
revolutions of 1,600 rpm we press L button on the gear shifting lever, by this we shift the to rque multiplier to
1 gear, now we increase the engine revolutions to 1,900 rpm and we press H button on the gear shifting
lever, by this we shift the torque multiplier back to 2 gear. We continue driving with the tractor. Now we turn
on the multiplier pre-selection switch. From this time, the automatic multiplier gear shifting system shifts
gears of torque multiplier without any intervention of the driver in the following way:
a - With the drop of engine revolutions under 1,600 rpm automatically shifts the multiplier to lower gear
(lowering travel speed)
b - When increasing the engine revolutions above 1,900 rpm, the multiplier automatically shifts to a higher
gear (increasing the travel speed)
The values 1,600 and 1,900 en
in this example are purely informative, in practice the number of revolutions is set by the driver
according to the specific use of tractor.
With multiplier pre-selection on, it is possible to shift the multiplier gears also manually on a gear shifting
lever, but only within the range of set values (engine revolutions); i.e. in the example presented in the range
of revolutions from 1,600 to 1,900 rpm, when reaching the saved revolutions for automatic shift of multiplier
gear the multiplier is automatically shifted without driver´s intervention. In this case (multiplier pre-selection
switch on), manual shifting of multiplier by buttons on gear shifting lever does not influence the values
(engine revolutions) that are saved in the system of automatic multiplier shifting. After turning the multiplier
pre-selection on the dashboard off (the control on the switch is not lit) it is possible to shift the torque
multiplier gears only manually by buttons on gear shifting lever.
Beware!
With tractor travel, when the pre-selection multiplier switch on the dashboard is off, the system of automatic
multiplier selection keeps on reading the values (engine revolutions) with every use of H or L buttons use on
gear shifting lever. After switching the multiplier pre-selection switch, the system of automatic multiplier
shifting uses the last read value (engine revolutions) i.e. values read with last usage of H and L buttons on
the gear shifting lever with multiplier pre-selection off.
Recommendation
Before switching the switch of multiplier on the dashboard, do the manual shift of multiplier gear when using
H and L buttons (once by H button and once by L button) on gear shifting lever with requested engine
revolutions. The values (engine revolutions) will be saved and after subsequent engagement of the multiplier
pre-selection switch on dashboard, the system of automatic multiplier shifting will automatically shift multiplier
gears according to these engine revolutions
With multiplier pre-selection switch on, in case of release of travel clutch, for example with gear shifting,
stopping and subsequent dead start of tractor or while using reversing, the system of automatic shifting of
multiplier sets an applicable multiplier gear with subsequent switch of travel clutch.

Travelling up the slope
Shift gears from higher to lower gears in time
when travelling up the slope so as to avoid drop of
engine revolutions under 800 rpm and do not allow
ride leading to stopping the engine for overload.
Travelling down the slope
Travelling down the slope without en engaged
gear is forbidden. If you are going down a longer
slope engage the lower gear the steeper the slope.
Engage the lower gear before the slope if possible.
Note: The gear with which you will reliably overcome
ascension, it is the one with which you will safely go down.

Activation of the front driving axle is indicated with the activated symbol on the switch and the symbol in the
instrument panel display. Switching-off is performed with the switch on the instrument panel.
a - front driving axle switched off
b - front driving axle switched on
The front driving axle of the decommissioned tractor (tractor is braked, engine is stopped, key in '0' positio n)
is switched on.
During sudden drop of air pressure in the air-pressure system of the tractor, the front driving
axle is automatically switched on.
Driving with engaged front driving axle
Use the front driving axle with slipping of the
rear wheels to increase the traction force of the
tractor. It is permitted to engage the front driving axle
on roads and hard surfaces up to 15 km/h (travel with
engaged front driving axle causes increased wearing
of front tyres).
Permanent engagement of the front driving axle is
permitted if there is a farming mechanism attached to the
front suspension. This condition is mentioned in the
instructions manual to the respective mechanism.
Maximum permitted speed when driving with these
attachments is 15 km/h.

Air brakes of trailers and semi-trailers
Air brakes of trailers (semi-trailers) and brakes of the
tractor are designed so that braking effects of both
vehicles are synchronised.
In case of a drop of pressure the transfer valve
disables the secondary consumers (differential lock,
disengagement of the front driving axle).
When driving with a trailer or semi-trailer the foot
brake pedals shall be coupled and secured by a latch!
With braking by one brake pedal the trailer air brakes
are not activated.
Warning indication of air pressure drop
Air pressure drop below 450 kPa is signalized by alit red
control bulb placed on a dashboard.
Tractor with braked trailer or articulated trailer
with pressured drop in air pressure system under 450
kPa must not continue in transport if there is not
increase in air pressure.

Hydraulic brakes of trailers
Connect hydraulic brakes of trailer or articulated
trailer to the quick couplings marked by an arrow.
Control of hydraulic brakes of trailers (articulated trailers)
and control of tractor brakes is done so that the braking
effect of both vehicles is synchronized. Working pressure
is derived by oil supplied by non-switched on/switched off
gear pump of hydraulics. Brake valve of the trailer is done
by the pressure of brake fluid from main braking rollers
depending on the force effecting on the brake pedal. The
pressure on clutch head must be 12 - 15 MPa with
maximum depression of brake pedal. Brake valve of trailer
prefers the function of brakes to the function of hydraulics.
If there are shocks when foot brake pedals are depressed
in the pipeline of hydraulic circuit, it is necessary to bleed
the hose from the brake valve to the quick coupling.
P11NX229
P11NE231
When driving with connected trailer or
articulated trailer, the pedals of foot brake must be
connected and secured by a valve! When braking with
one brake pedal, h
draulic brakes of the trailer are not
active.
Connecting and disconnecting quick couplings of trailer hydraulic brakes
When connecting and disconnecting quick couplings, take increased care with regard for
remaining oil which remains in the socket or in the plug of quick coupling. For ecological reasons , it
is necessary to remove this remaining oil after every disconnection of quick couplings with any
textile material.
Stopping the tractor - hand brake
Under normal conditions stop the tractor slowly. Shortly
before stopping:
1. Tread on the clutch pedal and brake the tractor by the
foot brake.
2. Move the main shifting lever to neutral position.
3. With each stop secure the tractor using the hand brake
against spontaneous moving off. Application of the hand
brake is indicated by a light on the dashboard.

Stopping the engine
After operation of the tractor when the engine was fully
loaded the engine must be cooled.
1. When the engine is started, leave it idling without load
for ca. 5 minutes.
2. Move the manual regulation lever to the idling position.
3. When the key is turned from 'I' position to '0' position,
the engine is stopped.
P15N061
Attention! When the engine is switched off, the engine control unit remains active for about 2
minutes because of storage of operation data. During this time the supply of current from the
accumulator must not be interrupted. Do not disconnect the accumulator before this time expires.
Leaving the tractor
Before leaving the tractor with the safety cab do not forget
to remove the key from the switching box in the '0' position
(in the 'I' and 'II' positions the key cannot be removed).
The tractor must be secured against accidental
movement.
1. The engine must be 'off'.
2. The tractor must be braked with the parking brake.
The engagement of a gear does not prevent the
tractor from getting in motion (the clutch is
disengaged)! If the tractor is standing on a slope, its
wheels must be additionally secured with wedges!
Lock the cabin.

When the engine is stopped and the hand brake is engaged, the drive of the front driving axle
is automatically disconnected.
Warning signalization of hydrostatic steering failure
Hydrostatic steering pump failure is with oil pressure drop
under 120 kPa behind a pump signalized on a dashboard
by an applicable symbol.
Note: When starting the tractor or with low engine
revolutions, the control may blink, if it switches off after
starting or increasing the revolutions, it is not a failure.
