U18N002
The word 'tractor' is derived from 'traction', which means towing.
A tractor is necessary for drawing or towing equipment, implements or carts that are suitably connected to
the tractor body.
The tractor can also be used as a driving machine, thanks to the Power Take-off or PTO shaft.
This manual provides instructions for the operation, maintenance and storage of all Zetor tractor models.
This material has been elaborated in detail to help you better understand maintenance and efficient
operation.
If you need information not provided in this manual or the services of a trained mechanic, please contact
Zetor Dealer/distributor at your location. Dealers and distributors are kept informed about the latest methods
of servicing tractors.
They are supplied with original spare parts and are fully supported by the manufacturer.
Through this manual
The use of the terms LEFT, RIGHT, FRONT and REAR must be understood, to avoid any confusion when
following the introductions. The LEFT and RIGHT means left and right sides of the Tractor when facing
forward in the driver's seat, Reference to the FRONT indicates the radiator end of the Tractor, while the
REAR, indicates the drawbar end (Fig. U18N002).
When spare parts are required, always specify the Tractor and engine serial number when ordering these
parts. (See Fig. U18N001).This will facilitate faster delivery and help ensure that the correct parts for your
particular Tractor is received. The tractor serial number is punched on a plate attached to the left hand side

INTRODUCTION & DESCRIPTION

General construction
The transmission case, clutch, clutch housing, engine and front axle support are bolted together to form
a rigid unit.
Front Axle and wheels
The 4WD front axle is a center-pivot, reverse Eliot type. The front wheel drive mechanism is incorporated as
a part of the axle.
The front wheel drive power is taken off the rear transmission and transmitted to the differential in the front
axle where the power is divided into right and left and to the respective final cases.
In the final cases, the transmitted revolution is reduced by the level gears to drive the front wheel. The 4WD
mechanism with level gears provides wider steering and greater durability.
Engine
The tractors are fitted with fuel efficient engine with 4 cylinders manufactured by Perkins.
Hydrostatic transmission
The tractor is equipped with a three-speed hydrostatic transmission with power steering, individual speed
ranges are shifted using the selector lever. The tractor is equipped with two pedals, for speed and for
forward / reverse travel. The tractor with an independent PTO is equipped with an electro-hydraulic clutch.
Brakes
Tractors are equipped with independent disc brakes. The handbrake lever is adapted for parking.
Rear axle and wheels
This is mounted on ball bearings and is enclosed in removable housing which are bolted to the transmission
case. The rim & Disc fitted with rear tires are bolted to the outer flange of rear axle.
Hydraulic system & Linkages
ZETOR Tractors are fitted with Live independent, very touch of hydraulic System.
Three point Linkages can be used for Category 1 type of implements.
Steering
It consists of hydrostatic power steering system, which has a hydraulic cylinder and tandem type hydraulic
pump.
Electrical system
A 12 Volt lead acid propylene battery is used to activate the engine through the starter motor and the
electrical system comprising horn, head lamp. Side indicator lamps, plough lamp, brake light, gauge lamp,
hazard lamp. Generator or alternator, fuse box also from part of the electrical system.
Warning: When operating the tractor at High speed, Do not attempt to make sharp turns by
using the brakes. This may result in overturning of the Tractor causing serious injury or DEATH.
Roll over protective structures (ROPS)
ROPS (ROLL OVER PROTECTION STRUCTURES)
15
ZETOR Tractors are equipped with a frame for the protection of operators.
In the case of cab tractors the frame is incorporated in the cab structure.
The objective of the frame or cab structure is to protect the operator in the event of a roll over and they are
designed to support the entire weight of the tractor in that event.
Each ZETOR ROPS frame or cab structure is designed and has been tested to meet industry and or
Government standards.
Included in these tests were all mounting bases and bolts or other fasteners.
DANGER
For ROPS frames to be effective and protect the operator, the seat belt provided must be worn in
order to keep operators within the ROPS protected area in the event of a roll over. Failure to use the
seat belt can still cause serious injury or death.
On some models the ROPS frame has a fold down feature, which can be used to enter low buildings etc.
Take care when lowering the upper section of the ROPS frame and take extreme care while driving the
tractor with the ROPS frame lowered.
Do not wear the seat belt with the ROPS lowered and please remember that the fold down facility is for
special circumstances only and must not be lowered for general use.
Use of the tractor with the ROPS lowered can cause fatal injuries
As the ROPS frame or cab together with the seat belt was designed to meet certain standards, they must be
maintained in good order and condition. To achieve this objective, both the structure and the seat belt should
be inspected on a regular basis (every time the tractor is serviced).
In the event that the seat belt is damaged or frayed, it should be replaced and in the event that the ROPS
frame or any part of the mounting structure is damaged or cracked, the faulty component must be replaced
with a new unit. Such a unit must meet all of the test criteria of the original unit. Fitment of an inferior item or
items affects the certification of the entire ROPS structure and the effectiveness of the structure in the event
of an accident. Drilling or welding of the ROPS structure is forbidden.
Damage of the ROPS
Cabin type
If the tractor has rolled over or the ROPS has damaged
(such as striking an overhead object during transport), it
must be replaced to provide the original protection. After
an accident, check for damages to the 1.ROPS.2.Seat
3.seat belt & seat mountings. Before you operate
a Tractor, replace all damaged parts.
U18N003
Warning: Do not weld, drill or straighten the ROPS.
Warning: Never attach chains, ropes to the ROPS for pulling purposes; this will cause the
Tractor to tip backwards. Always pull from the Tractor drawbar. Be careful when driving through
door opening or under low overhead objects. Make sure there is sufficient overhead clearance for the
ROPS fatal injuries.
Warning: If the ROPS is removed or replaced, make certain that the proper hardware is used to
replace the ROPS and the recommended torque values are applied to the attaching bolts.
Warning: Always wear your seat belt if the tractor is equipped with ROPS.

The Roll Over Protective Structure (ROPS) has been
certified to industry and/or government standards. Any
damage or alternation to the ROPS, mounting hard-ware,
or seat belt voids the certification and will reduce or
eliminate protection for the operator in the event of a rollover. The ROPS, mounting hardware, and seat belt
should be checked after the first 100 hours of tractor and
every 500 hours thereafter for any evidence of damage,
wear or cracks. In the event of damage or alternation, the
ROPS must be replaced prior to further operation of the
tractor.
The seat belt must be worn during machine operation
when the machine is equipped with a certified ROPS

Description of tractor controls
CONTROLS, INSTRUMENTS & OPERATIONS
43
The following pages in this section detail the location and function of various instruments, switches and
controls on your tractor. Even if you operate other tractors, you should read through this section of the
manual and ensure that you are thoroughly familiar with the location and function of all the features of your
new tractor.
Do not start the engine or attempt to drive or operate the tractor until you are fully accustomed to all the
controls. It is too late to learn once the tractor is moving.
Particular attention should be paid to the recommendations for running-in to ensure that your tractor will give
long life and dependable service for which it was intended.
If in doubt about any aspect of the operation of the tractor consult your ZETOR tractor dealer / distributor.

UCL18NN012
The battery disconnector is located on the front axle bracket under the right front corner of the hood (A).
Turn the battery disconnector handle in the direction of the arrow (B) to disconnect the battery from the
tractor's electrical installation. To connect the battery to the tractor's electrical installation, turn the battery
disconnector handle counterclockwise. Battery connection is indicated by a visible green field (1).
(C) The position of the battery disconnector handle when the battery is connected.
(D) The position of the battery disconnector handle when the battery is disconnected.
When the tractor is parked, disconnect the battery using the battery disconnector (1). If the
tractor is parked for a long period of time, it is necessary to recharge the battery at least once
a month due to self-discharge.
When the engine is switched off, the engine control unit remains active for about 2 minute
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.
After connecting the battery using the battery disconnecting switch, wait at least 30 seconds
before turning on the ignition key.

Caution: Do not operate any implement at a high speed than is specified for it. When making
adjustments to the implement stop the engine to avoid serious injury. When leaving the tractor stop
the engine, and remove the key. Set the parking brake.
Warning:
1. When working with a rotary implement on hard ground, the PTO switch must be set to the OFF
position to prevent the PTO from rotating. If this is not done, the rotating implement blades
come into contact with the hard ground under the implement, causing the entire tractor to
move. This accident can result in serious injury or even death.
2. When using PTO-driven implements, special precautions must be taken to ensure that no
persons or bystanders are in the area around the tractor. Contact with rotating implement
blades can result in serious injury. The warning signaled by the PTO flashing indicator light
allows the operator to remember that the PTO is in the ON position and will start rotating
immediately when the clutch pedal is released or the implement is lowered (or both).
3. The rotational speeds specified by the implement manufacturer must not be exceeded under
any circumstances, as this could result in serious damage to the tractor / implement and / or
serious injury to bystanders.

Important:
As soon as the implement operated by the pressure oil from the quick couplers reaches the end of the
stroke, return the lever to the middle (neutral) position, when there is no oil pressure in the quick couplers;
otherwise the oil will flow through the relief valve. When the oil is pushed through the relief valve for a longer
period of time, oil becomes overheated. When using the tractor hydraulic system to drive the front loader, do
not use the SCVs and the loader at the same time.
Remote hydraulic control valve coupler connecting and disconnecting
When connecting and disconnecting the quick-couplers pay increased attention with regard to
the residual oil that remains in the socket or on the plug of the quick-coupler. For environmental
reasons after every disconnection of quick-couplers this residual oil must be removed with any
textile material.
Connection
1) Do not forget to stop the engine before connecting the implement.
2) Move the lever of the double-acting valve forward and backward 4 to 5 times to release the pressure in the
tractor's hydraulic lines. Otherwise it may be difficult to attach the couplers and hydraulic fluid may splash out
of the hoses and strike the eyes when coupling.
3) Remove any dirt around the couplers. If dirt enters the hydraulic parts, the system may fail.
4) Open the dustproof clutch cover on the tractor and connect the implement coupler. You should hear
a click when the coupler is engaged.
5) Pull the hydraulic hose to check that the couplers are correctly connected.
6) Start the engine and check for operation and leaks.
Disconnection
1) Do not forget to stop the engine before disconnecting the implement.
2) Relieve the residual pressure in the hydraulic hoses of the machine and the tractor by moving the lever of
the double-acting valve 4 to 5 times backwards and forwards.
3) Remove any dirt around the quick couplers.
4) Keep the implement unloaded by removing all load (e.g. by lowering or placing the implement on the mat).
If the hose is disconnected when the implement is loaded, it will be difficult to reconnect it in the future.
5) Disconnect the quick couplers by pulling them backwards.
6) Close the dustproof cover of the quick couplers of the tractor. Cover the quick coupler of the disconnected
implement so that no dirt can penetrate.
Warning:
- Never connect or disconnect the implement hydraulic hose while the pressure in it is not released
or the engine is running. It is hard to connect and disconnect the hose and hydraulic fluid can be
sprayed from the hose, and get into your eyes or skin.
- Stop the engine and wear protective glasses and gloves before work.

Before starting the engine, perform pre-operation check as
described in the chapter Safe Operation of Tractor.
(1) Sit into the driver's seat.
(2) Depress the foot brake.
(3) Move the hydraulic lever in the lower position.
(4) Move the gearshift lever to neutral.
(5) Insert the ignition key and turn it to the ON position.
(6) Check that all indicator lights are working.
(7) The operator must turn the key to the ON position. The
glowing circuit is automatically activated. The operator
must wait until the glowing indicator light switches off.
When it switches off, turn the key to the start position and
start the engine.
U18N049
(8) Check that the engine is running and all warning lights
are off
Important:
Never turn the key to the start position while the engine is running as this can cause serious damage
to the starter and engine flywheel.
Only engage the starter for a period of not more than 10 seconds.
If Engine does not start, rest the starter for about 20 seconds and try again for a maximum of 10
seconds.
If the engine does not start after repeated attempts, refer to the fault tracing guide.
Important: Especially in cold weather, always allow the tractor to idle for a while to warm up &
build up sufficient oil pressure to ensure normal operating temperature for longer engine life.
Stopping the engine
- After light work let the engine idle for a while and turn the key off.
Important: After long or heavy work allow the engine to idle for 5- 10 minutes and turn the key
off.
Warming up
When starting the engine allow it to warm up to operating temperature by allowing it to idle 5-10 minutes to
ensure full lubrication and operating temperature. Failure to do so can shorten engine life substantially.
Warming up in cold weather
Cold weather will change the viscosity of the oil, resulting in a reduced oil pumping capacity, which can
cause damage to the engine if it is not warmed up correctly. It also causes problems with the hydraulic
system and the synchromesh in the transmission.
Correct times for warming up are:
Temperature Time for warming up
Above 50°F 5~10 min.
50°F ~ 32°F 10~20 min.
32°F ~ 14°F 20~30 min.
14°F ~ -4°F 30~40 min.
Below - 4°F Over 40 min.
Running-in Period
Make sure to observe the following instructions for use in the first 50 hours of machine operation.
(1) Do not drive at excessive speed and do not overload the tractor.
(2) Only use the tractor's full power if the engine is sufficiently warmed up.
(3) Do not run the engine to maximum speed.
(4) Perform regular maintenance and change oil and fluid after 50 hours of use.
(5) To refill and replace engine oil, see Maintenance.
