HLL Operation
The HLL is controlled by means of two
handles located on the right-hand con-
trol panel in the cab:
•
draft control handle (2); and
•
position control handle (3).
Position control
1. Set the draft control handle (2) to the
foremost position in the direction of
the tractor travel.
2. Set the necessary height on the im-
plement above the soil by means of
the position control handle (3).
The digit “1” on the control panel corre-
sponds to the transport position of the
RHL and the digit “9” – to the minimum
height of the implement above the soil.
If it is necessary to restrict the maximum
lifting height (for example, due to the
possibility of breakage of the parts of the
rear axle), set the maximum lifting height
by means of the handle (3) and move
the adjustable stop (1) to the latter.
Draft control
Use this method of adjustment when
working with the mounted implements
(ploughs, cultivators). Move the draft
control handle (2) to the foremost posi-
tion in the direction of the tractor forward
travel (digit “9” on the control panel).
Connect the implement to the RHL by
means of the position control handle (3).
On entering the furrow move the handle
(3) to the foremost position and adjust
the desirable soil treatment depth by
means of the handle (2).
On leaving the furrow and subsequent
entering the same (when performing the
tillage), use the position control handle
(3) without touching the draft control
handle (2).
If it is impossible to achieve the con-
stancy of the soil treatment depth due to
unevenness of the soil density, limit the
maximum depth by means of the posi-
tion control handle (3) (combination con-
trol mode) having memorized the re-
spective digit on the control panel.
