2.17 Control of rear lift linkage (RLL) with the hydraulic lift
2.17.1 General information on rules of RLL control
RLL is controlled with control panel (figure 2.17.1) and remote buttons 4 and 5 (figure
2.17.3). If there are any failures in the RLL electronic-hydraulic control system, a diagnos-
tics annunciator 5 (figure 2.17.1) displays information on the failure and, if necessary, the
operation of RLL control system is blocked.
2.17.2 RLL control panel
RLL control panel, located on a side console in tractor cab, is shown in figure 2.17.1.
1 – retainer of RLL control handle blocking; 2 – button of “dampening” mode activa-
tion; 3 – annunciator of “dampening” mode activation (orange color); 4 – handle to adjust
depth of soil tillage; 5 – troubleshooting annunciator (red color); 6 – handle to adjust height
limit of linkage uplifting; 7 – handle to adjust speed of lowering; 8 – handle to select control
method; 9 – annunciator of linkage lowering (green color); 10 – annunciator of linkage up-
lifting (red color); 11 – handle of RLL control.

The order of RLL control is the following:
- set a method of control depending on type of operation with handle 8 (figure 2.17.1).
Turning the handle clockwise against the stop is a position method of control; contraclock-
wise against the stop – draft control; in between – combined control; the combined control
is preferential;
- set the required admissible height of implement uplifting in transport condition with han-
dle 6. Turning the handle clockwise against the stop corresponds to max. uplifting, contra-
clockwise against the stop - to min. uplifting;
- set the tillage depth with handle 4. Turning the handle clockwise against the stop corre-
sponds to min. depth, contraclockwise up to “A” position corresponds to max depth; turn-
ing the handle contraclockwise against the stop corresponds to floating position;
- lower the linkage by moving handle 7 to a lower fixed position.
Then, during the operation it is required to adjust an implement for optimal operation con-
ditions:
- with handle 8 – combination of control methods;
- with handle 4 – depth of soil tillage.
- with handle 7 – speed of RLL lowering. Turning of the handle clockwise against the stop
corresponds to the max. speed of lowering, turning the handle contraclockwise corre-
sponds to min. speed lowering.
