ZETOR
This Operator’s Manual for the Zetor tractors, which we are presenting to you will help you to
become familiar with the operation and maintenance of your new tractor.
Although many of you have rich experience with the operation of other tractors, please, read the
information contained in this Operator’s Manual very carefully.
In the Manual you will find a lot of new information and get a perfect overview of how to use the
tractor with maximum efficiency during various kinds of work.
If you observe the rules of tractor operation and maintenance and driving safety, your new tractor will
become your reliable and long-term friend.
The manufacturer of the tractor wishes you thousands of hours of satisfactory work.

Driving operatio
n
zHoses of the hydrostatic steering, brakes and fuel system must be checked and replaced immediately
if any signs of damage are found. These are some examples of hose damage signs: - cracks on the
hose surface, releasing of pretensioning of hose connection (which can be verified by easy removal of
the hose from the connection) and mechanical damage of the hose. Hoses with indicated service life
must be replaced immediately after the expiration of the service period.
zThe brakes and steering must be in the perfect condition all the time.
zDuring driving on roads with trailers and tools the brake pedals must be connected with a latch.
zDriving downhill without an engaged gear is forbidden.
zPay special attention when driving on a slope and muddy, sandy, icy or uneven ground.
zObserve the maximum set angle of slope availability 12° with tractors with front drive axle.
zRespect the total permissible weight of the tractor and trailer specified on the data plate of the tractor
or on the rear wheel mudguard.
zDo not use the differential lock when driving into a bend.
zIt is forbidden to get into and out of a moving tractor.
zWhen driving with machines attached to the rear hitches the load of the steered axle must not drop
below 18 % of the current weight of the set.
zWhen driving the tractor with agricultural machines attached to the front three-point hitch, reduce the
driving speed to 20 km/h.
zDuring aggregations of the tractor with machines pay attention to possible worsening of stability of the
aggregated unit which may be influenced by the connected machine.
zDuring aggregation of Zetor tractors with machines and implements with high tensile resistance when
the engine speed drops and the engine tends to stall, the 1R, 2R, 3R reduced gears must not be used
for the work with these machines (risk of shaft twist-off).

Risk of the tractor overturnin
g
The risk of the tractor overturning is increased especially when the following is used:
za narrow wheel gauge
zinappropriate tractor travelling speed
ztravel on the slope along a contour line or turning on the slope
zdriving through ditches, depressions, near edges of ditches, chuckholes, steep slopes or when driving
on edges of water courses and water areas
zdriving up the steep slope, risk of overturning the tractor back
zdriving with the trailer, semi-trailer or machine with the three-point hitch connection that lifts the centre
of gravity of the tractor or combination of vehicles
ztilting of trailers and semi-trailers
Not all the cases that can cause overturning of the tractor are listed. Pay attention to driving of
the tractor and be prepared to resolve situations which can threaten stability of the machine.
Transportation of persons, operation
zThe number of persons transported by the tractor must not exceed the number specified in the
technical certificate of the tractor.
zPersons that are not authorized to work with the attached implement must not stand between the
tractor and the hitched machine (implement).
zBefore putting the tractor in motion make sure there is no person or obstacle in the driving direction.
Recovery, pushing
zUse the tow bar or rope fixed in the front hitch to rescue the sunken tractor.
Never use chains! There is a risk of death in case that the chain breaks!
It is dangerous to stay near the tow rope during the rescue operation.
zIt is forbidden to use tractor axles (individual travel wheels) as a winch with extrication of the stuck
tractor.
zThe front hitch is only used to tow or rescue the stand-alone tractor, i.e. without the trailer or another
additional device. More information in the chapter TRANSPORT USE.
Never rescue the tractor when reduced gears are shifted.
zWhen pushing another vehicle (trailers, semi-trailers, etc.) with the tractor, never use beams or bars
freely inserted between the tractor and the pushed item.
zIn case of use of the tractor for wrecking or towing purposes, use only the rear hitch.
zWhen towing the tractor, the reduction gear shift lever must be in the neutral position.

Leaving the tracto
r
zPark the tractor only on an even land and where not possible, support with a shim assy.
zDo not park the tractor with an attached implement in the lifted position.
zUsually use the left-hand side tractor door when leaving the tractor. Look round whether any vehicle is
coming, that could jeopardize your safety when leaving the tractor.
zUse steps and handles when leaving the tractor. When leaving the tractor by the right-hand side door
pay attention being in space of shifting lever and hand throttle control.
zBrake the tractor with parking brake before leaving tractor with running engine.
zWhen leaving the tractor with tools connected in the front or rear three-point hitch, the three-point
hitch with these tools must be lowered to the lower position.
The tractor must not be leaved with the tools in the upper position in three-point hitches.
zDo not forget to brake the tractor with parking brake (shift the gear), remove the key from key switch
and lock the cab before leaving the tractor.
zAt tractor equipped with reversor gear, shift the reversor lever into forward drive position.
With stopped engine only
zAll work connected with refuelling, cleaning, lubricating and adjusting the tractor or attached
implements may only be performed with the engine and moving parts of the tractor stopped except
functional checks of the brakes, hydraulic system and charging.
zBefore removing the side plates of the hood it is always necessary to stop the engine. The tractor
engine can only run in a closed building or room if sufficient ventilation is ensured. Exhaust gases are
harmful for health.
Fire prevention principles
zRefuel the tractor best after the end of work and with the engine stopped.
zDo not refill fuel up to the top of the fuel tank in summer. Wipe spilt fuel immediately.
zDo not refuel the tractor near open flame and do not smoke.
zDo not smoke and do not use open flame when inspecting the battery electrolyte level.
zMake sure that fire safety instructions are strictly observed in environments with an increased danger
of fire (hay-lofts, straw-stacks, etc.).
zThe tractors are not equipped with a fire extinguisher from the production plant.
