External Hydraulic Circuits Control By Means Of A Joystick; External Hydraulic Circuit Front Outlets And Front Three-Point Hitch - Zetor CRYSTAL HD 150 Operator's Manual

External hydraulic circuits control by means of a joystick

External hydraulic circuits control, controlled by controls (III) and (VI) can be switched to external hydraulic
circuits control mode by means of a joystick (1). The switch is done by switching the switch (2), which is
equipped with a lock against undesired pressing.
Switch switching (2) is not signalized. Buttons on the upper part of joystick (1) are not
functional
In external hydraulic circuits control mode by means of the joystick( 1 ), the controls ( III ) and ( IV ) are not
functional, their function is taken over by the joystick ( 1 ) including floating positions and stable oil flows with
adjustable flow capacity and also setting the time limit with controls ( 3 ) in individual sections of external
hydraulic circuits.
If the tractor is equipped with an auxiliary switchboard for external hydraulic circuits, the front
outlets and front three-point hitch are controlled with the joystick (1), which cannot be used for
control of external hydraulic circuits controlled with controls (III) and (IV).

External hydraulic circuit front outlets and front three-point hitch

The front outlets of the outer circuit are located on the front panel of the tractor (A). Quick couplings (1) and
(2) are pressure coupling, quick coupling (0) is directly connected to the transmission housing and is
intended for return oil from external hydraulic appliances.
Standard tractor design:
If the tractor is fitted with a front three-point hitch it is controlled by the controller (IV).
If the tractor is fitted with front outlets (quick couplings), these are controlled by the controller (III) and the
quick coupling (5) and (6) of the section (III) on the rear panel are not mounted (B).
Tractor in version with auxiliary switch for front hydraulic circuits:
The front outlets of the external hydraulic circuit and the front three-point hitch (more in the HITCHES
section) are controlled by a joystick, the rear panel has a full number of quick couplers (C).
In this case, the (III) and (IV) controllers can not be switched to the joystick control mode.
