①
Position control
 To set the position (height) of the rear implement,
move the position control lever up/down during
the engine is running. Generally, this lever is
used for tiller, fertilizer distributor, mower, rake
and other rear implements.
1.Push the position control lever forward and let
the implement down by its own weight.
2.Move up the lever to desired position, the rear
implement shell be located on the position
corresponding to the lever position.
3.If necessary, fix the lowest position of the lever
with the stopper A at the desired position.
②
Draft control
 The working depth of the implement under the
draft control is controlled automatically by the
draft load of the implement that detected from
draft load sensor bracket and transmitted to the
lift control valve. Generally, this mode is used for
the implement which receives the draft load.
In this case, operate the lever as follows.
1.Remove the draft sensor stopper of the upper
link bracket.
2.Move the position control lever forward fully
(Down) and let the implement down by its own
weight.
3.The draft load delivered to the lift control valve
will be determined according to the position of
the draft control lever.
That is, the more the lever moves back (up), the
more the implement rises up by light draft
load.
4.If you want to lift the rear implement, use the
position control lever instead of the draft control
lever.

first, and set the draft control lever depending on the draft load. At this time, working depth can be
controlled by the draft control lever under position control mode.
