Instructions and Descriptio
n
The word 'tractor' is derived from 'traction', which means towing.
The tractor is required to tow or draw working equipment, an implement or a trailer that is attached to the
body of the tractor by means of a suitable hitch.
The tractor can also be used as a drivetrain, thanks to a power output called a PTO or a PTO shaft.
These operating manual is prepared in accordance with the operating, maintenance and storage instructions
for the relevant Zetor tractor model.
The manual has been designed to help you better understand the maintenance and efficient operation of this
machine.
If you require any information not provided in this manual or require service from a trained mechanic, contact
your local ZETOR TRACTORS a.s. dealer/distributor.
Dealers/distributors are kept informed about the latest service procedures for tractors. They have original
spare parts in stock and have full service support from the machine manufacturer.
In this manual, the use of the terms LEFT, RIGHT, FRONT and REAR must be unified to avoid any
confusion when following these instructions.
LEFT and RIGHT means the left and right sides of the tractor when looking from the driver's seat towards the
front. The reference to FRONT means the end of the tractor radiator, while REAR means the end of the
drawbar (see the picture).
When ordering spare parts, always specify the tractor and engine serial numbers when ordering.
This will make their delivery easier and faster and ensure that you receive the right spare parts for your
particular tractor.
The tractor's serial number is stamped on a plate attached to the right side of the tractor (see the picture).
For easy reference, we recommend you to write this number in the space reserved for the owner's personal
data.

Descriptio
n
Overall Design
The transmission case, clutch, clutch housing, engine and front axle support are bolted together to form
a rigid unit.
Front Axle and Wheels
The front axle is a 4WD, center pivot type.
The front wheel drive mechanism is incorporated as a part of the axle. The front wheel drive power is taken
from the rear-mounted transmission and transmitted to the front axle differential, where it is divided into right
and left half axles and to the final drives.
In the final drives, the transmitted speed is reduced by the axle gears for front wheel drive.
This 4WD mechanism with axle gears allows a wider range of steering and longer service life of the
mechanism.
Engine
The tractors are equipped with fuel-efficient three-cylinder engines manufactured by Yanmar.
Clutch and Transmission
A single-plate dry clutch is used in these tractors.
Tractors with IPTO (independent power take-off) are equipped with a hydraulic clutch assembly.
The transmission has twelve synchronized forward and twelve synchronized reverse gears with the Fast-
Slow selector lever.
Brakes
Zetor tractors are equipped with disc brakes controlled by a foot pedal. There is a parking brake lever
installed for parking.
Rear Axle and Wheels
It is mounted on ball bearings and is enclosed in a removable housing that is attached to the transmission
case.
The rims and discs, assembled with the rear tires, are attached to the mounting points of the rear axle.
Hydraulic System and Hitches
Zetor tractors are equipped with active (i.e. the system is running) independent systems. A three-point hitch
may be used for Type 1 (N) implement category.
Steering
Steering consists of a hydrostatic power steering system that has a hydraulic cylinder and a tandem
hydraulic pump.
Electrical System
A 12 V battery is installed to start the motor using the starter.
The electrical system includes a horn, headlights, turn signal lights, tachometer, hour meter, brake lights,

INTRODUCTION & DESCRIPTION

Roll-Over Protection Structure (ROPS)
Zetor tractors are equipped with a frame to protect the operator.
On tractors with a cab, this frame is built into the cab structure.
The objective of the frame or the cab design is to protect the operator in the event of rolling over, they are
designed to support the full weight of the tractor.
Each ROPS or cab structure, as well as any mounting brackets and screws or other fasteners, have been
designed and tested to meet safety and government standards.
Danger
For the ROPS frames to effectively protect the tractor operator, the operator in the driver's seat
must be wearing a seat belt. This will keep the driver inside the ROPS-protected area in the event of
a rollover. Failure to use the seat belt can result in serious injury or death.
Some models of the ROPS frame can be folded, which can be used when entering low buildings, etc.
Be careful when lowering the top part of the ROPS and be very careful when driving with the ROPS lowered.
Do not use the seat belt with the ROPS lowered and remember that the folding mechanism is intended for
special use only and not for daily routine operation.
Using a tractor with the ROPS folded can cause serious injuries.
Since the ROPS frame or ROPS cab, together with the seat belt, have been designed to meet safety
standards, they must be maintained in good order and in good condition.
For maximum safety, both the frame and seat belt must be regularly inspected (whenever the tractor is
serviced).
If the seat belt is damaged or frayed, it must be replaced and if the ROPS frame or any part of its mounting
structure is damaged or cracked, the defective part must be replaced by a new one.
Such a part must meet all test criteria of the original set.
The use of poor quality component(s) affects the certification of the entire ROPS and the effectiveness of the
structure in the event of an accident.
Drilling or welding or making any unprofessional modifications of ROPS is prohibited.
ROPS (ROLL OVER PROTECTION STRUCTURES)
13

ROPS damage
If the tractor has rolled over or the ROPS has been damaged (for example, by hitting a low overhead object
or during transport), the ROPS must be replaced to provide the guaranteed protection.
After an accident, check for damage on:
1. ROPS.
2. Seats
3. Seat belt and seat mountings.
Replace any damaged parts before operating the tractor.
CCLHTN003
Do not weld, drill or straighten the ROPS.
Warning: Never attach chains or ropes to the ROPS for towing; it will cause the tractor to roll
over. Always use the points specified on the tractor for towing. Be careful when driving through open
doors or under low overhead objects. Ensure sufficient overhead clearance for ROPS to avoid fatal
injuries.
Warning: When removing or replacing the ROPS, ensure that the correct fasteners are used to
replace the ROPS and that the fastening bolts are tightened to the recommended torque values.

1- Seat Belt
2- Forward / Reverse Position Adjustment Lever
Before operating the tractor, it is important to adjust the seat to the most comfortable position and ensure
that it is properly locked in its position.
NOTE:
Do not use solvents to clean the seat. Use warm water with detergent.
Warning: Do not place your hand between the seat and the guide rail when adjusting the seat.
You may be injured.
Danger: Check that the seat is properly locked in its position before driving the tractor.
Danger: Always use the seat belt when the ROPS is installed/lifted. Do not use the seat belt if
the ROPS is folded down or not installed. Check the seat belt regularly and replace it if it is frayed or
damaged.

2- Backrest angle adjustment lever
To change the seatback angle, raise the lever on the left of the seat.
Then, adjust the seatback angle with the lever pulled. Release the lever after adjustment . Make sure that the
lever is returned and the seat is firmly fixed after adjustment.
Seat Suspension Adjustment
The seat cushion can be adjusted according to the driver's weight.
Turning the cushion adjustment knob counterclockwise towards 50 kg position will make the cushion softer.
By turning the knob clockwise towards 130 kg position, the cushion becomes harder.

Use of rops and seat belt
Precaution to avoid tipping
Safe parking of the tractor
Keep riders off tractor
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 roll-
over. 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
.
Failure to do so will reduce or eliminate protection for the
o
p
erator in the event of a roll over
.
U18N136
Do not drive where the tractor could slip or tip.
Stay alert for holes and rocks in the terrain, and other
hidden hazards.
Slow down before you make a sharp turn.
Driving forward out of a ditch or mired condition could
cause tractor to tip over backward. Back out of these
situations if possible.
U18N137
Before working on the tractor:
Lower all equipment to the ground.
Stop the engine and remove the key.
U18N138
Do not allow other persons to ride on the tractor besides
the operator.
