FRONT THREE-POINT HITCH
The front three-point hitch is used for
suspending the agricultural machines
and implements of the category II at-
tached to the tractor front as per the ISO
standard.
The maximum lifting power of the front
three-point hitch is 24 kN. This type of
three-point hitch suits for suspending
round weight only.
When transporting the attached
implements the hitch must al-
ways be locked hydraulically in
the raised position with a ball
valve installed on the tractor L.H.
side over the front axle.
This hydraulic lock is recommended
even if no machine is connected to the
front three-point hitch.
FRONT THREE-POINT HITCH CONTROL
The hitch is fitted with two double acting
hydraulic cylinders to which the oil is
supplied from the external additional
distributor. Lifting and lowering is con-
trolled with the lever of the outer dis-
tributor controller (1):

FRONT THREE-POINT HITCH REGU-
LATION AND HYDRAULIC LOCKING
The rate of lowering the hitch with im-
plements attached may be regulated
with a return throttle valve.
The hydraulic locking of the front three-
point hitch is performed in any position
with a ball valve by turning the lever from
the A position through 90° (perpendicu-
lar to to the valve axis) to the B position.
