Driving Operation - Zetor FORTERRA HSX 120 Operator's Manual

Driving operation

Hoses of the hydrostatic steering, brakes and fuel system must be checked and replaced if any signs

of damage are found. These are some examples of hose damage signs: - cracks on the hose surface,
releasing of pre-tensioning 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.
During driving on roads with trailers and tools the brake pedals must be connected with a latch.

The brakes and steering must be in the perfect condition all the time.

Driving downhill without an engaged gear is forbidden.

Switching the reversing lever at a speed over 10 km/h is forbidden.

Pay special attention when driving on a slope and muddy, sandy, icy or uneven ground.

Observe the maximum specified inclination angle, i.e. 12°.

Respect the total permissible weight of the tractor and trailer specified on the data plate of the tractor

or on the rear wheel mud-guard.
Do not use the differential lock when driving into a bend.

It is forbidden to get into and out of a moving tractor.

When driving the tractor with agricultural machines attached to the front three-point hitch, reduce the

driving speed to 15 km/h.
When driving with machines attached to the rear hitches the load of the steered axle must not drop

below 20% of the current weight of the set. With the driving speed reduced to 20 km/h the load of the
steered axle may drop to 19% of the current weight of the set (set below 4.5 t) or to 18% of the current
weight of the set (set exceeding (4.5 t).
During 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.
During 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 twist-off).
