Controlling front three-point hitch

The hitch is equipped with two single acting hydraulic
cylinders which are supplied with oil from an additional
hydraulic distributor. To lift or lower, use lever (a) of the
additional distributor.
1 position lifting
2 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 (a) 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 1 and 2 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.

in the front part of the tractor (2).
