Controlling front three-point hitch

The hitch is equipped with two single acting hydraulic

hydraulic distributor. To lift or lower, use lever (b) of the
additional distributor.
3 position lifting
4 position lowering
N position locking the hitch
P position not to be used
If the tractor is equipped with front three-point
hitch, use lever (b) to control it. When the front three-
point hitch is used, quick couplers cannot be
connected as they are pressured together with the
front three-point hitch! When you finish using the
front three-point hitch and want to use the section
with quick couplers 3 and 4 with connection to the
front three-point hitch, raise the arms of the front
three-point hitch to the transport position and move
the front three-point hitch lever to the 'locked'
position.

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.
