Front Three-Point Hitch; Controlling Front Three-Point Hitch; Adjusting The Lowering Rate Of The Front Three-Point Hitch - Zetor Proxima CL 80 Operator's Manual

*Front three-point hitch

It is designed for attachment of frontally carried
agricultural machines and implements in accordance with
ISO 8759-2.
During transport of a carried implement the
hitch must always be hydraulically locked in the lifted
position with valves that are installed on the left side
of the tractor over the front axle.
This hydraulic lock is recommended even in case no
machine is attached to the three-point hitch.

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 (b) of the
additional distributor.

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.
