hydraulic circuits
FHD18N039
Front three-point hitch is controlled only by a joystick. Turning on the control of the front three-point hitch is
done by switching a switch (a), which is equipped with a latch against undesired pressing.
Switching the switch (a) is not signalized. The buttons on the upper part of the joystick are not
functional.
By moving the joystick from ( N ) position backward, there is the lift of arms of front three-point hitch. Do not
use the locked position at the end of the control track ( B ).
By moving the joystick from ( N ) position to the front, there is lowering the arms of front three-point hitch.
After overcoming the increased resistance, the control can be shifted to floating position ( A ), in which the
control is locked.
The front three-point hitch is controlled by the joystick only. Switching on the front three-point hitch is
triggered by switching on the switch (a), which is equipped with a lock against accidental pressing.
Switching on the switch (a) is signaled by the backlit symbol on the switch. Buttons at the top of the
joystick are not operating.
Move the joystick from the (N) position to the rear to raise the arms of the front three-point hitch. Do not use
the locked position at the end of the controller runway (B). Move the joystick from the (N) position to the front
to lower the front three-point hitch arms. After exceeding the increased resistance, you can move the
controller to the floating position (A) in which the actuator is locked.

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.
