It is necessary to create overpressure in
the cab for the proper function of AC.
Thatřs why we recommend to shut all
windows, doors and cab roof cover.
COOLING THE CAB
For fast cooling the inner space of cab
move the heating shut off lever (2) into
the left position (i.e. fresh air inlet is
closed). Choose the desired blower
speed by the four speed blower switch
(position 1, 2, 3). Set outlets with desired
angle to avoid direct blowing to persons
in the tractor cab (possible injury
because of intensive cooling of person řs
body).
AC OPERATION
With switched AC and permanently
closed heating shut off lever (2) in left
position (i.e. fresh air circuit closed) the
inner air is breathed out. Persons could
become tired. Thatřs why we recommend do move the lever (2) into the right
position (fresh air opened) immediately
after cooling down and reduction of the
inner temperature to desired level. The
fluent regulation of system is carried out
by partial opening of the heating valve
with heating control lever (3).
At the same time dry air from AC system
becomes moisture by this way.

PUSH BUTTON - MAX
Push button (keypad) - max serves for
increasing the engine speed. Engine
speed can be increased by keypad max. by two ways.
1. Pulse pressing the keypad causes
gradual change of engine speed.
2. Permanent pressing the keypad
causes the immediate increase of
engine speed. Engine speed is increased up to time when you release
the keypad.
This keypad controls the memory if
combined with keypad MEM.
PUSH BUTTON - MIN
Push button (keypad) - MIN serves for
decreasing the engine speed. Control of
keypad MIN is equal to control of keypad
MAX for increasing the engine speed (1,
2).
This keypad controls the memory if
combined with keypad MEM.
PUSH BUTTON - MEM
Push button (keypad) - MEM serves for
entering, recalling and resetting the
engine speed in memory of system. This
keypad is used either separately (1) or in
connection with keypads MIN or MAX
(2, 3).

speed increase or decrease.
FUNCTION OF ELECTRONIC GOVERNOR
1. Setting the temporary memory
2. Resetting and deleting the temporary
memory
3. Setting the permanent memory
4. Permanent memory recall - H/O lamp
is off
5. Permanent memory recall - H/O lamp
is on
6. Memory reset - return to pedal control
Engine speed, determined for memorizing to memory system, can be set
either by throttle control or by foot
throttle control (throttle pedal). Enter,
recall and reset of memory is possible
on the keyboard of hand throttle control.

2. In case the maximal engine speed is
being entered it is not possible to
enter the value smaller than 1500
RPM. If you will try it the system will
automatically enter 1500 RPM.
Two values can be entered into
permanent memory i.e. chosen minimal
and maximal engine speed. These
values will be memorized in the
permanent memory even after stopping
the engine and removing the key from
the key switch.
If you will enter the new minimal and
maximal engine speed into the
permanent memory the previously

DRIVING UPHILL
Shift from higher to lower speed
in time when going uphill, to
avoid dropping the engine speed
below 800 RPM and stopping the
engine by overloading.
DRIVING DOWNHILL
Driving downhill without the shifted gear is forbidden. If driving
down the long hill, shift so low
gear the sharper one the hill is. If
possible shift the lower gear
before driving downhill.
Remember: The gear you use reliably
for driving uphill is safely suitable for
driving downhill.
SERVICE BRAKES
Service brakes are of disc wet type,
hydraulically actuated with double pedal,
and automatic pressure compensator.
Both brake pedals must be
latched together when driving on
the road.
Use unlatched pedals only for
braking right or left wheel
separately when working in
terrain and fields.

HYDRAULIC TRAILER BRAKES
Hydraulic trailer brake control is synchronized with braking the tractor including the
braking effect. Operating pressure is activated by pressure of oil from hydraulic
pump (1). The hydraulic valve (2) is introduced in the circuit of hydraulic pump. The
hydraulic pump is of gear type (pump can not be disengaged).
The hydraulic trailer brake valve is controlled by the brake fluid pressure activated in
master brake cylinder depending upon the force on brake pedal. The pressure in
brake coupling (4) must be 12 - 15 MPa at maximal press on the brake pedal. Trailer
brake valve prioritizes the function of brake to control of hydraulic. Do not forget to
bleed the trailer brake valve (2) by vent screw (3) when bleeding the service brakes.
In case there are hydraulic shocks in hydraulic circuit if applied service brake pedals
it is necessary to bleed the hose (5) coming from brake valve (2) to quick-coupler
(4).

b - Front axle is engaged
Front driving axle is engaged at stopped
tractor (stopped tractor, stopped engine).
At tractors with pin diff. lock of
front driving axle the differential
lock must not be locked when
driving on the road! Danger of
accident when turning!
DRIVING WITH ENGAGED FRONT
DRIVING AXLE
Use the front driving axle when
slipping the rear wheels and for
increasing the traction force.
Driving with engaged front diving
axle on the road and hard
surface causes an excessive
wear of front tires.
Permanent engagement of front driving
axle is possible if a front agriculture
machine or implement is attached to the
tractor. This is specified in operator řs
manual of a particular machine.
Maximal allowed speed of tractor with
such attachment is 15 km/h.

P - Position control - Implement attached in the three point hitch is automatically
maintained in the constant height (position) with regard to the tractor.
M - Mix control - is a combination of position and draft control. This is suitable
especially for tilling in soils with various resistance.
D - Draft control - Implement attached in the three point hitch is automatically
readjusted depending upon the change of soil resistance.

RESPONSE RATE CONTROL LEVER
Lever controls the distributor in hydraulic
valve and this divides the flow of oil to
inner or outer circuit. The oil flow in inner
circuit is the smallest if the lever is
moved into forward horizontal position.
Hydraulic response rate is reduced by
restriction of the oil flow when selected
draft or mix control, for example when
tilling in various soil conditions.
ELECTRO-PNEUMATIC CONTROL OF HYDRAULIC
This is an additional control of hydraulic that enables lifting the three-point hitch into
its highest position without changing the position of inner circuit control lever. This
device is controlled either by electrical switch on right cab pillar (1) from driver ’s seat
or by outer electrical switches on both ends of rear fenders (2) from outside.

CAB CONTROL SWITCH
Cab control switch is used for lifting the
implement when turning the tractor in the
end of field. Pressing the switch lifts
implement. Implement is lowered into
previous position destined by inner
circuit lever after turning the switch into
off.
CONTROL SWITCH ON FENDER
Control switch on fender makes
attaching the implement easy. Driver can
handle movement of three point hitch
lower links from outside. The hitch is
lifted when the switch is pressed. The
implement is lowered into previous
position destined by inner circuit lever
after releasing the switch.
When the tractor is equipped
witch pick up hitch do not lift the
rear three point hitch by switches
on fenders up to the highest
position! Danger of damaging the
hitch!
USE OF SWITCHES
Operator must stand outside the
operating range of attached implement when manipulating with
three-point hitch by means of
electrical switches to avoid
catching by implement or injury.
For lifting the implement into transport
position you must use the control lever
of inner circuit. Move the lever into upper
position. The implement must be
lowered to ground when stopping the
tractor with attached implement (the
implement must not be left in lifted
position).

HYDRAULIC OUTER CIRCUIT
Hydraulic outer circuit delivers the pressure oil into hydraulic implements connected to hydraulic outer outlets equipped with quick-couplers. Quick-coupler
sockets “ rear (A) and front (B) have
inner diameter 12,5 mm and they correspond to the international standard
ISO 5675.
MAX. OIL CAPACITY SUPPLIED FROM HYDRAULIC OUTER OUTLETS
Max. 12 litters of oil can be temporarily supplied from outer outlets for filling
the hydraulic cylinders of attached implements. This is considered with
standard oil level in transmission i.e. up to upper mark of oil dipstick and if
the tractor does not work in hilly conditions. For increasing the supplied oil
capacity it is possible to add up to 15 l of oil into transmission.
When bigger supply of oil the transmission oil level can drop so low that the
pump of hydraulic and transmission might draw in the air. In this case not
only the pump and also the Hi-Lo or PTO clutch could be damaged
It is necessary to pay attention when disconnecting and connecting the hydraulic
quick-couplers because of residual pressure being in female or eventually male of
quick-couplers. Taking ecology into consideration remove the spilt oil by a textile
cloth after any disattaching the quick-couplers.

CONNECTION OF MACHINES AND IMPLEMENTS TO HYDRAULIC OUTER
CIRCUIT
Connection of machines and implements combined with more parts
Agricultural machines that are combined from more parts ( combinators, skids, and
harrows), are often equipped with outer frames which are hinged to the middle
frame. This configuration needs to control folding of outer frames. These outer
frames are folded by independent hydraulic cylinders. For folding, cylinders are
connected with outer circuit of tractor hydraulic. When working with such implement
it is necessary to control folding of outer frames by raising the control lever of outer
circuit upward. Moving the control lever upward ensures that the pressure oil in
quick-coupler "1" lifts frames to vertical (transport) position. Quick-coupler "2" is
connected with drain.
Connection of rotary hydromotor
If the rotary hydromotor is connected with hydraulic outer circuit, the oil return line
must be ever connected with quick-coupler "0".
Connection of reversible hydromotor
If the reversible hydromotor is used the oil lines must be connected with quickcouplers "1" and "2". In this case both lines must be equipped with relief valves
which will limit the pressure peaks when stopping the machine. The oil return line
from these valves is connected with quick-coupler "0".

ATTACHING MACHINES TO THREE POINT HITCH WITH CBM HOOKS
Lower and upper links of hitch are equipped with semi-automatic ends -CBM.
They serve for easy, two-phase attaching and disattaching the implement to
the three point hitch without necessary direct action of the driver. They are
operated by means of cables from the driver ’s place. Lower links are attached to the
implement within the first phase at reverse move and by subsequent lifting the three
point hitch. Top link of three point hitch is attached by the driver from the cab within
the second phase. The top link is assembled in one from four openings of the
support. First the implement must be equipped with attaching balls-CBM and the
length of hitch axis must be adjusted with adjustable spacer (at reinforced three point
hitch only).
At tractors equipped with reinforced three point hitch “ CBM, the fine adjustment is
carried out by moveable collar with handles.
The collar of lift link must be ever set with handles in direction of driving after
adjusting the length.
LOCKING THE SIDE SWING OF
LOWER LINKS
Insert the pin (1) into opening II
(implement of category II) or into
opening I (implement of category I).
Hitch is set in the middle position. Fine
adjustment of hitch can be done by
means of bolt (2). Blocking the side
swing of links is done when transporting
the implement or when working with
machines which need precise towing
behind the tractor.
At reinforced three point hitch the
stabilizers can be adjusted within their

BLOCKING AND UNBLOCKING THE FRONT AXLE KNEES (EXTENSIONS)
Blocking:
- Unscrew the plug (1). Safe it for assembling at later unblocking.
- Screw down the stop tube (3) with lock washer (4) into the thread hole of spring
bushing (2) instead of plug.
Insert the screw M 10x1,25 (5) into the stop tube and screw it down into the nut (6).
This nut is inside of rubber spring (7). The spring (8) is out of function by this way
and the knee is blocked. Unblocking the front axle knee is done by the opposite way.
After blocking and unblocking the front axle knees check the front wheel toe-in.
Block and unblock the sprung
axle knee in loaded status only
(by the own weight of tractor).
Kingpin of wheel is shot up by
the force of spring after unblocking the unloaded axle knee.
Disassemble the bushing of
spring only if the sprung knee
needs to be completely disassembled. Because the special
tool must be used for disassembling let to do this job in a
specialized workshop.

BLEEDING THE HYDROSTATIC STEERING SYSTEM
- Start the engine and let it run for 1 minute at low idle.
- Turn the steering wheel several times to both directions (A) at engine low idle run.
- At engine max. speed turn the steering wheel three times alternatively slowly and
quickly to both directions up to wheel stops (A).
- Stop the engine and lower the front wheels to the ground.
- At 2WD tractors loosen the bleeding plug located in the upper cover of steering
cylinder (this is necessary for filling the circuit of hydrostatic steering by fresh oil)
and after draining oil tighten the plug. The plug is accessible after sliding out the
battery and battery support (B).
F 251
At all actions within bleeding look
at the oil level in tank to avoid
aerating of steering system.
After bleeding check and eventually add
the oil into tank up to the mark of oil
dipstick (C). Check for leakage of all
connections and lines.

CHANGING THE HOSES OF HYDROSTATIC STEERING
Hydrostatic steering hoses must be exchanged after four years from time of
manufacturing (time is marked on hose surface) or after 3 600 hours of tractor
operation, eventually immediately after founding any symptoms of damage i.e. hose
sweating, local bulging, leakage of oil at fittings and on hose surface, mechanical
damage of hose surface up to steel wire cord or damage of yarn braid at low
pressure hoses).
Steering-ability is kept even in case of hydrostatic steering pump failure or if
the engine stops but the steering force on the steering wheel is bigger
Tractor can be driven into the nearest place for repair at reduced
transportation speed.
Don’t keep the steering wheel in the stop steering angle positions (max. time
is 20 seconds), otherwise the oil is excessively heated in the hydrostatic
steering circuit.

- Close both draining valves after
draining the coolant (let the heating
valve opened).
- Fill the cooling system with antifreeze
mixture up to neck of expansion tank
and close it by overpressure cap.
- Start the engine and let it run
approximately 1 minute.
- Add the coolant in expansion tank up
to mark "MAX".
The minimal possible coolant level is
approximately 40 mm under the sealing
edge of filler. Close the expansion tank
by overpressure cap.
At tractor Z 10641 disassemble the
screw on the additional radiator and
check the quality of bleeding. Clear
liquid must drain from the radiator after
loosening the screw.
Never fill the cooling circuit by

CLEANING THE HEATING FILTERS
Filters are located under grills above the
front windshield from outside of the cab.
Regenerate filters by kicking out, or by
pressure air blowing through, according
to the stage of clogging. Daily check for
clogging. Exchange the strong clogged
filters.
Tractors are not equipped with
special filters of cab intake air.
That’s why tractors are not intended for operation with aerosols and other health dangerous
mediums.
MAINTENANCE
OF
AIRCONDITIONING
The most important part of
maintaining the AC system is
cleaning the AC condenser (this
is located in front of engine
radiator).
The clogged AC condenser reduces not only the affectivity of
AC system but also the affectivity
of engine cooling.
Loosen the wing nuts keeping nocdenser to the upper partition of bonnet.
Tilt the condenser and blow it out by
pressure air or wash it by pressure
water.
Within the right function of AC the air
humidity is condensed in the roof space
of cab. Condensed water is drained by
hoses in cab pillars and water drains in
the bottom part of pillar. Thatřs why it is
necessary to keep hoses clean for
proper draining the condensed water.
Tractors Z 11641 equipped with
AC are able to work on full load
up to ambient temperature 36“C
without any restriction.

DRAINING THE CONDENSED WATER
FROM AIR TANKS
Drain the condensed water by inclining
or pressing the protruded part of valve.
Air tanks are located in front of rear axle.
At tractors Z 8621 - Z 10641 one air tank
is assembled as a standard or ∗ two air
tanks located on left and right hand side
of tractor (in case air brakes are
assembled).
At tractor Z 11641 both air tanks
are assembled as a standard.
CHECKING THE LEAKAGE OF AIR
SYSTEM
- Fill the air tank to the max. pressure
- The pressure must not drop down by
more than 10 kPa after 10 minutes at
stopped engine.
Daily inspect the system for leaks
before operation with trailer. The
indicator lamp on the dashboard
is on when the air brake system
fails or after dropping the pressure under 420 kPa.
OPERATING PRESSURE OF AIR
BRAKES
At single and double hose brakes the
pressure in double hose coupling (red
cover) is 735 „ 20 kPa and the pressure
in single hose coupling is max. 600 kPa
(in time when the air pressure regulator
releases the compressor
air blows
out).

TIRE MAINTENANCE
Regularly check the outer surface of
tires and verify that tires are without
defects in the side part and that the cord
is not damaged.
Discard tires with defects.
INFLATING THE TIRES
Basic values of recommended inflation pressure are mentioned in the following
tables. Regularly check for the inflation pressure before operation. Check the
inflation pressure at cold tires. The tractor air pressure regulator can be used for tire
inflation. This regulator serves for maintaining the air pressure, filling tires and
serves as a safety valve. Remove the wing nut of regulator (or regulator rubber plug)
when inflating the tire and assemble a hose for tire inflating instead of it. Screw down
the hose fitting up to the end of thread for pushing the back pressure valve. In case
the maximal pressure 0,6 MPa (or 0,7 MPa at double hose brakes) is in air brake
tanks the tire can not be inflated. In this case it is necessary to reduce the pressure
by valve for draining the condensed water located in the bottom part of air tank. The
wing nut (or rubber plug) must be reassembled on the air pressure regulator after tire
inflating.
182
RECOMMENDED TIRE INFLATION PRESSURE FOR FRONT WHEELS
Sum of load capacity for both tires used at front axle must not exceed allowed axle load capacity. Values of allowed axle load
capacity is mentioned in main technical parameters of the particular type of tractor. Tires of different design must not be
assembled on the same axle of tractor.

BASIC SERVICE INFORMATION
Battery "minus" pole must be ever connected with the ground and "plus" pole connected with alternator. Vice versa connected battery destroys the complete electronics of alternator. If starting the tractor by means of another battery or auxiliary
source don’t forget to connect "plus" to "plus" and "minus" to "minus". Disconnect
battery by removing the connector from tractor ground (-) if changing any part of
charging circuit. Avoid possible short circuit on connectors.
204
F 297
BATTERY
Battery (1) is accessible after removing
the front grill of bonnet.
∗ Battery switch (3) is located on the
left-hand side under the cab. This is
accessible from outside.
BATTERY MAINTENANCE
Maintain the battery clean, good fixed to
the vehicle. The fixing device mustn’t deform the battery case. Electrolyte level
mustn’t be under the minimum mark that
is on the case.
F 298
Add distilled water only!
1. First study the operator’s manual for working with batterry.
2. Safe your eyes by glasses or by safety shield!
3. Electrolyte is a caustic agent that ’s why keep attention when working with
electrolyte! Neutralize the skin and wear stained by electrolyte with soap
water. Wash them by clean water.
4. Hydrogen is released from electrolyte at charging the battery and this
creates the explosive mixture being mixed with the air. That ’s why
manipulation with open flame and smoking at battery is forbidden!
5. The explosion might be caused by a spark created at manipulation with
battery terminals when the closed charging circuit!
6. Keep children out of battery and electrolyte!
7. Discarded battery is ecologically dangerous reject. Let it scrap by
specialists (service network). They will do it free of charge when buying
the new battery.
205
CHARGING AND MAINTAINING THE
BATERY
A) Charging on the vehicle and outside the vehicle
1. Systematic overcharging and discharging of battery damages and
shortens its life. Correctly adjusted
charging system maintains battery
near to the fully charged status. At
set level of voltage (13,8 - 14,4 V) in
charging system and average tractor
operation it is sufficient to check and
maintain the level of electrolyte by
distilled water once per six month.
2. At heavier operation and another
level of regulated voltage it is necessary more frequent checking the
level of electrolyte. Overcharging the
battery on vehicle (more than 14,4 V)
causes bigger loose of electrolyte.
3. It is necessary to charge the battery
removed from the vehicle or in the
vehicle which is not in operation (see
storage of charged batteries with
electrolyte). It is also suitable to
charge battery in vehicle before
wintertime and after wintertime. In
winter season and strong frost the
electrolyte might be frozen at almost
discharged battery (density of
3
electrolyte 1,12 - 1,15 g/cm ) in this
case the life will be substantially
reduced (disintegration of active
4.

3.
agent and destroy of battery case).
Heavily discharged battery (density
3
of electrolyte lower than 1,07 g/cm )
might be frozen already at several
degrees below zero.
Charge the battery by current that is
0,1 of total battery capacity (or lower)
up to fully charged status.
Charging device with constant
voltage 14,4 V can be also used.
Charging time can be max. 30 hours
according to status of discharging.
Fully discharged battery must be
charged as soon as possible, otherwise its full capacity can not be restored.
Charged battery
Battery is considered as fully
charged if all battery cells generates
the gas with same intensity. If the
3
electrolyte density is 1,28 g/cm in all
cells and if the total voltage of battery
is within 15,3 - 16,5 V, measured
with the prescribed charging current.
Status of full charging is confirmed
when the received density of electrolyte and level of voltage is not
changed within farther two measurements following after two hours.
For example the charging status for
your orientation: status of charging
corresponds to density of electrolyte.
Charging status is characterized by
206
density of electrolyte and is
measured by densimeter. Every cell
needs to be measured.
Status of charging = density of
electrolyte

C) Storage of charged battery with
electrolyte
1. Before storage the battery must be
charged up to final symptoms of
charging. It must be disconnected
from charging system, cleaned and
with plugs.
2. Battery that is built into a plastic case
from polypropylene must be charged
after three month of storage because
of smaller self-discharging.
3. Intervals for checking the status of
electrolyte are: when charging the
battery or minimally once per 6
month, battery is maintained by
adding the distilled water! If some
electrical components are permanently connected even at disconnected key switch (for example
Warning) it is necessary to check the
status of charging “ i.e. voltage w/o
load and electrolyte density min. 1x
after 1 month.

ALTERNATOR
Alternator is accessible after removing
the right side shield. Charging status is
indicated by the red indicator lamp on
the instrument panel.
Damaged
indicator
lamp
bulb
12 V 1,2 W must be immediately exchanged.
All wires connected with the
alternator must be disconnected
when repairing tractor by electric
arc welding. Protect the wire
"+B" against short circuit.
ALTERNATOR MAINTENANCE
- Protect the alternator against penetration of water or diesel fuel when washing
and cleaning the tractor.
- Battery must be never disconnected from alternator within the operation!
- The alternator must never run without load i.e. with disconnected terminal "+B"
and connected terminal "+D". When increased engine speed, this status would
create excessively high voltage of alternator and the voltage would damage the
alternator electronics.
- Never create the short circuit of any alternator connector within the operation!
- Alternator must not be additionally excited. Alternator electronics is damaged in
this case.
- Keep the perfect electrical connection of alternator terminals and perfect alternator ground.

Clean daily when working with front attached machines if necessary in shorter periods
Max. period - 2 years.
Change hoses at least after four years from time of their production.
New hoses must not be older than two years from time of their production mentioned on hose surface
Max. period - five years from time of tractor manufacturing.
Max. period - five years from time of air-tank manufacturing or after accident.
This covers the adjustment of front asymmetric headlight and adjustment of brake indicator light switches (max. play between
switch and foot brake pedal stop must be 0,5 to 1,0 mm).
In summer season - every 100 hours.

In case of leakage remove the failed piston rod sealing, flush out the shock absorber by petrol and fill it up with 70 cm of
shock absorber oil.
225
PLANNED TECHNICAL MAINTENANCE ’ MIDDLE REPAIR
This is carried out after 2400 hours.
AT TRACTORS Z 8621 - Z 10641
1. Disassemble the compressor case of turbocharger with
inlet manifold.
2. Disassemble spiral of compressor.
3. Remove impurities sedimented in compressor case and on
the rotor by brush with solvent.
Cleaning by sharp subject or by wire brush is
forbidden!
Do not repair eventually deformed blades!
LUBRICATING THE ELEMENTS OF HYDRAULIC BRAKES
At moving parts i.e. brake cylinders, clutch cylinders and brake
equaliser, coat the sliding surfaces from sealing rings in
direction to the outer dust rings by special vaseline for
hydraulic brakes (for example Pentosin special). In the same
time inspect rubber parts of brakes. Exchange damaged
rubber parts. Exchange all rubber parts at least up to five
years from date of tractor manufacturing.
INSPECTING THE TIGHTNESS OF TURBOCHARGER AND
THE BEARING PLAY
In case the oil penetrates from bearing case round the shaft
and in case the allowed radial and axial bearing play is
exceeded, let the turbocharger repair in specialised workshop.
Exchange the hose at inlet manifold and at outlet of lubrication
oil from turbocharger when reassembling the turbocharger to
the engine. Fix the proper tightness of both connections. Fill
0,2 litres of engine oil into inlet oil opening when reassembling
the turbocharger to the engine.
The inner conservation of turbocharger must be done if
the tractor is a long time out of operation.
This is done even after short starting the engine. That „s why
we recommend to start the turbocharged engine minimally
once per three month at tractor out of operation and let the
engine run for few minutes. The inner conservation is done by
this way.
226
PLANNED TECHNICAL MAINTENANCE ’ GENERAL REPAIR
General repair of tractor must be done in case that its farther
operation is not economical anymore. If many parts need
repair and the complete technical status of tractor jeopardizes
the safe operation.
The middle life of engine and transmission is 6000 hours if all
regulations for maintenance are kept according to the
technical documentation of producer when working in normal
climatic conditions and in even terrain.
This number of hours is valid if the following tractor working
conditions are taken into consideration:
tillage and sowing preparation
sowing
harvesting
agricultural transportation
15 - 25 %
10 - 15 %
10 - 20 %
40 - 65 %
If the tractor works in hilly conditions the life of engine and
transmission is reduced by 15-20 %.
If the tractor works in worse climatic conditions the life of
engine and transmission is reduced by 15-20 %.
Note:
Front driving axle is also considered as a transmission.
TECHNICAL MAINTENANCE OF TRACTOR AFTER
GENERAL REPAIR
Run-in the tractor after general repair according to rules for
running in the new tractor. Do the maintenance as on the new
tractor.
