Tractor an introductio
n
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
of the engine body (See Fig. U18N001), For easy reference, we suggest you to write the number in the

INTRODUCTION & DESCRIPTION

Descriptio
n
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.
INTRODUCTION & DESCRIPTION

Roll over protective structures (ROPS)
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
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.
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.

How to adjust the Seat
NOTE: Do not use solvents to clean the seat. Use warm water with a little detergent added.
Before operating a Tractor it is important to adjust the seat to the most comfortable position & check whether
it is properly locked in its position. Figure 1 identifies the seat fitted to your Tractor.
For sliding seat
Caution: Do not put a hand between the seat and the slides when adjusting the seat position.
You can get injured unexpectedly.

Seat suspension adjustment knob
To adjust the seat correctly, turn Weight adjustment knob clockwise or counterclockwise, while seated in the
driving position.
Caution: Do not put a hand between the seat and the slides when adjusting the seat position.
You can get injured unexpectedly.
Danger: Check whether the seat properly locked in its position before driving the tractor.
Danger: Always use the seat belt when the ROPS is installed. Do not use the seat belt if
a foldable ROPS is down or there is no ROPS. Check the seat belt regularly and replace if frayed or
damaged.

Danger: Always use the seat belt when the ROPS is installed. Do not use the seat belt if
a foldable ROPS is down or there is no ROPS. Check the seat belt regularly and replace if frayed or
damaged.
Cushion strength adjustment
The seat cushion can be adjusted according to the weight of the driver.
Turning the cushion adjustment lever counterclockwise to the 50 kg position makes the cushion lighter, and
turning the lever clockwise to the 130 kg position makes the cushion heavier.
