Control of the front 3-point hitch
If the tractor is equipped with the front 3-point hitch, the lever (b) is used to control it. The
quick couplings must not be connected when the front 3-point hitch is used because they are
pressurized together with the front 3-point hitch!
On termination of the work with the front 3-point hitch, for further use of the quick couplings 3 and
4 section with the connection of the front 3-point hitch, it is necessary to lift the front 3-point hitch
arms to the transport position and to move the lever of the front 3-point hitch valve to the position
'closed'.
The hitch is equipped with two single-acting hydraulic
cylinders, into which the oil is supplied from the auxiliary
hydraulic distributor. The lifting and lowering is performed
by the control lever (b) of the auxiliary distributor.
