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 reduced gears must not be used for
the work with these machines
(
risk of shaft twis
t
-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
To recover a tractor that has sunk in mud use a tow bar or rope attached to the front hook
Never use chains! Rupture of the chain represents a danger of death!
zDuring recovery it is dangerous to stand near the towing rope.
zIt is prohibited to use the tractor axles (individual wheels) as a winch for releasing a sunken tractor.
zThe front hook should be only use to recover the entire tractor, i.e. without any trailer or another
attached implement.
zNever recover the tractor with reduced gears engaged.
zWhen pushing other vehicles (trailers, implements, etc.) with the tractor never insert free wooden
blocks or bars between the tractor and the pushed vehicle.
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.
