Belarus 2022.6 Operator's Manual page 101

During operation with wide-cut implements in order to facilitate crossover contour
following (seeding machines, cultivators and etc.) and reduce load on RLL, it is required to
provide free movement in vertical plane of one lower link in relation to the other. To do this,
adjust the lifting rods so that one lower link moves freely in vertical plane in relation to the
other. Such adjustment is made by exchanging pins, mounted on the yoke as specified in
section 4.3.3.2. "Lifting rods". RLL is controlled by RLL control panel located in the cabin
and by remote buttons on rear wheels wings which ensure setting of RLL lower links at the
required height. An operator chooses the way to adjust the RLL position in manual mode
by turning the adjusting lever on the RLL control panel. Remote RLL control buttons allow
the operator to maintain prompt control of RLL during coupling of assembly unit.
Electronic system for the rear lift linkage control provides the following performance
capabilities for RLL:
- adjustment of lower links lifting and lowering speed;
- limiting of lower links rising height;
- choice of the required way of adjustment of lower links positions;
- adjustment of soil processing depth;
- possibility to work with implements with depth control of operating parts travel
height (depth adjustment is carried out by the implement support wheel).
Note – The rules on RLL control are specified in subsection 2.17 "Lift linkage con-
trol".
RLL control system provides the following adjustment methods of mounted and
semi-mounted implements and their operating parts:
1. For the implements and aggregated units having no support wheels:
- draft adjustment (depth adjustment is carried out according to link resistance of the
implement);
- position adjustment (the implement is held in the predetermined position in relation
to the tractor frame);
- mixed adjustment (draft and position adjustment in any correlation).
2. For the implements and aggregated units having support wheels:
- mixed adjustment (draft and position adjustment in any correlation).
