FRONT THREE-POINT HITCH
The three-point hitch has been designed
to attach the frontal carried agricultural
machines and implements of category II
according to ISO standard.
During transportation of the car-
ried implement the front three-
point hitch must be always locked
hydraulically in the lifted position
by means of ball valves located
on the LH side of the tractor
above the front axle.
This hydraulic locking is also recom-
mended in case that no implement be
attached to the front three-point hitch.
FRONT THREE-POINT HITCH CON-
TROL
The three-point hitch is equipped with
two single-acting hydraulic cylinders into
which the oil is supplied from additional
hydraulic distributor. Lifting and lowering
is controlled by the control lever of addi-
tional distributor (1):
position 6 lifting
position 5 lowering
position N hitch locking
ADJUSTMENT OF THE LIFTING
SPEED OF THE FRONT THREE-POINT
HITCH
Before starting to work with the attached
implement to the front three-point hitch,
we recommend to adjust the throttle
valve (3) so that the time needed to
lower the implement from the highest to
the lowermost position ranges from 1 to
1.5 sec. When rotating the valve body to
the left (in the arrow direction), the lower-
ing speed is increased. During adjust-
ment the valve control levers of the front
hitch must point horizontally.
