1 – lowering speed control handle (clockwise – quicker, anti-clockwise – slower); 2 – handle for selecting
the control method (clockwise – position one, anti-clockwise – draft one, intermediate – combination con-
trol); 3 – handle for control of limitation of the hitch linkage lifting (clockwise – maximum lifting, anti-
clockwise – minimum lifting); 4 – handle for controlling the soil treatment depth (clockwise – less depth,
anti-clockwise – more depth); 5 – hitch linkage lifting indicator (red); 6 – hitch linkage lowering indicator
(green); 7 – hitch linkage control handle (upwards – lifting, downwards – lowering, when pressing the
handle more in the bottom position – deepening the implement during the soil treatment, intermediate
position – disabled); 7a – interlock switch (transportation) – mechanic interlock of the handle (7) in the top
position by shifting the switch to the right; 8 – diagnostic alarm (see “Fault Diagnostics”), 9 – damping but-
ton, 10 – damping indicator.
The procedure of control of the rear hitch
linkage is as follows:
• depending on the character of job, set
the control method by means of the
handle (2) (Fig. E-36);
• set the treatment depth and height of
the implement lifting in the transporta-
tion position by means of the handles
(4) and (3), respectively.
• to lower the hitch linkage, shift the
handle (7) to the bottom fixed position.
In this case, the indicator (6) goes out.
When performing the job, it is necessary
to set the optimum conditions of opera-
tion of the mounted implement:
• combination of the control methods by
means of the handle (2);
• lowering speed by means of the han-
dle (1);
• soil treatment depth by means of the
handle (4).
In case of the draft control, the system
limits automatically the correction fre-
quency to Hz in average.
In case of intense heating of the hydrau-
lic system oil, the correction frequency
should be reduced by shifting the handle
(2) to the position method of control and
the handle (1) – towards the turtle.
