Upper draw-bar

The upper draw-bar (1) has adjustable length. It is
attached to the tractor to the console openings.
When extending the upper draw-bar you must
make sure that both the joints are unscrewed from the
draw-bar pipe to the same length.

*Front three-point hitch

It is designed for attachment of frontally carried
agricultural machines and implements in accordance with
ISO 8759-2.
During transport of a carried implement the
hitch must always be hydraulically locked in the lifted
position with valves that are installed on the left side
of the tractor over the front axle.
This hydraulic lock is recommended even in case no
machine is attached to the three-point hitch.

Adjusting the lowering rate of the front three-point hitch

Before the start of work with an implement attached to the
front three-point hitch it is recommended to adjust the time
necessary to lower the implement from the highest to the
lowest position to 1 - 1.5 s by setting the throttle valve. By
turning the valve body to the left (in the arrow direction)
you will increase the lowering speed. During the
adjustment the valve levers of the front hitch must be
directed horizontally.

Controlling front three-point hitch

The hitch is equipped with two hydraulic cylinders that are
supplied with oil from the integrated hydraulic distributor.
The lifting and lowering is controlled by the control lever of
the integrated distributor (1):
Position 3 Lifting
Position 4 Lowering
Position N Hitch lock
