2.17 Control of lift linkages

RLL is controlled with control panel (figure 2.17.1) and remote buttons 4 and 5 (fig-

ure 2.17.3). If there are any failures in the RLL electronic-hydraulic control system, a diag-

nostics annunciator 5 (figure 2.17.1) displays information on the failure and, if necessary,

the operation of RLL control system is blocked.

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 activation; 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 meth-

od; 9 – annunciator of linkage lowering (green color); 10 – annunciator of linkage uplifting

(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; con-

traclockwise 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

handle 6. Turning the handle clockwise against the stop corresponds to max. uplifting,

contraclockwise against the stop - to min. uplifting;

- set the tillage depth with handle 4. Turning the handle clockwise against the stop

corresponds to min. depth, contraclockwise up to "A" position corresponds to max depth;

turning 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

conditions:

- 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

corresponds to min. speed lowering.
