2.14 Rear lift linkage control
2.14.1 General information
RLL control is controlled with the control panel 31 (figure 2.1.1) and remote buttons
3 and 4 (figure 2.14.2). If there are failures in RLL electronic-hydraulic control system a di-
agnostics annunciator 9 (figure 2.14.1) displays information on the failure and, if neces-
sary, operation of RLL control system is blocked.
2.14.2 RLL control panel
RLL control panel, located on a side console in tractor cab, is presented in figure
2.14.1.
1 – handle to adjust speed of lowering; 2 – handle to select control method; 3 –
handle to adjust height limit of linkage uplifting; 4 – handle to adjust depth of soil tillage; 5
– annunciator of linkage uplifting (red color); 6 – annunciator of linkage lowering (green
color); 7 – handle to control RLL; 8 – retainer of blocking of RLL control handle; 9 – failure
diagnostics annunciator (red color); 10 – button to engage “dampening” mode; 11 – an-
nunciator of “dampening” mode activation (red color).
Figure 2.14.1 – RLL control panel
Order of RLL control is the following:
- (figure 2.14.1) set a method of control depending on operation character using the
handle 2. Turning of handle clockwise against the stop – position method of control; contra-
clockwise against the stop – draft control, in between – combined control, the combined con-
trol is preferential;
- set a required height of implement uplifting in transport condition with the handle 3.
Turning the handle clockwise against the stop corresponds to max. uplifting, contraclock-
wise against the stop - to min. uplifting;
- set tillage depth with the handle 4. Turning the handle clockwise against the stop
corresponds to min. depth, contraclockwise up to “A” position corresponds to max depth;
turning of the handle contraclockwise against the stop corresponds to floating position;
- move the linkage using the handle 7 to a lower fixed position.
Then during operation it is required to adjust a mounted (semi-mounted) implement
for optimal operation conditions:
- with the handle 2 – combination of control;
- with the handle 4 – depth of soil tillage.
- with the handle 1 – speed of RLL lowering and uplifting. Turning of the handle
clockwise against the stop corresponds to the max. speed of lowering (uplifting), turning the
handle contraclockwise corresponds to min. speed lowering (uplifting).
