5.3 Lift linkage

5.3.1 General information

While operating front and rear lift linkage via the ground control console the opera-
tor shall stay beyond the reach of three-point lift linkage and take to the account the exter-
nal dimensions of projecting parts of the lifted implement.
ATTENTION: BEFORE LEAVING THE TRACTOR FOR ANY TIME PERIOD, THE
LINKED IMPLEMENT SHALL BE PUT ON THE GROUNG INDISPENSABLY!
ATTENTION: MAXIMUM LIFTING POWER VALUE OF A HINGE MECHANISM (FLL
OR RLL) AT THE SUSPENSION AXIS DETERMINATES TECHNICAL OPERABILITY OF
THE LIFT LINKAGE, BUT NOT PERMISSIBLE MASS OF THE IMPLEMENT COUPLED
THROUGH IT. PERMISSIBLE MASS OF THE IMPLEMENT DEPENDS ON THE CENTROID
OVERHANGING LENGTH AGAINST THE SUSPENSION AXIS, AND IT IS LIMITED BY
PERMISSIBLE LOADS ON THE TRACTOR AND BY CONTROLLABILITY CRITERION!
The RLL and the FLL provide semiautomatic coupling of agricultural implements.
The RLL and the FLL correspond to ISO 4254-3.

5.3.2 Three-point rear lift linkage

The three-point rear lift linkage of "BEARUS-1822.3/1822 .3/2022.3/2022 .3" is
made according to State Standard GOST 10677 and ISO 730. Basic parameters of RLL,
specified in Table 5.1 and in Figures 5.3.1, 5.3.2, are given with standard rear tires
(580/70R42 both single and doubled), mounted on the tractor and with standard static ra-
dius, specified by the manufacturer.
Rear lift linkage as defined by subsection 3.17 "Rear lift linkage", consists of three
links (upper one and two lower links) with front ends articulated via hinged joint with the
tractor, and with rear ends articulated with free hinged joint for the purpose of connection
to the attachment pins of the implements coupled. The RLL is designed for connection of
implements for tail positioning to a tractor, for link power transfer during operation and ad-
justment of their position during operation, or run at transport position. The RLL provides
for coupling of the following types of implements and instruments:
- mounted implement fixed in three points (upper one and lower links);
- semimounted (lower links);
- semimounted with a cross arm to the suspension axis of lower links.
ATTENTION: MOUNTING OF A CROSS BAR OR TRAILING SUSPENSION AXIS,
BEING THE PART OF IMPLEMENTS SET FOR COUPLING OF SEMIMOUNTED, SEMI-
TRAILED AND TRAILED IMPLEMENTS FOR FULFILLMENT OF DIFFERENT WORKS
WHEN SPEED DOES NOT EXCEEDS 15 KM/H, TO THE ENDS OF LOWER LINKS OF
REAR LIFT LINKAGE!
Sizes and structure of RLL of tractors "BELARUS-1822.3/1822 .3/2022.3/2022 .3"
make it possible to couple all implements, having the corresponding dimensions of at-
tachment elements of connection triangle shown in RLL diagram
Rear lift linkage diagram of type "LL-3" is shown in Figure 5.3.1.
Rear lift linkage diagram of type "LL-2" is shown in Figure 5.3.2.
