4.3 Lift linkage

4.3.1 General information

While operating front or rear lift linkage with the remote control console (if avail-
able), the operator shall stay beyond the reach of the three-point lift linkage and also con-
sider the sizes of the uplifted implement projecting parts.
ATTENTION: BEFORE LEAVING THE TRACTOR FOR ANY TIME PERIOD, IT IS
REQUIRED TO LOWER THE IMPLEMENT TO THE GROUND!
ATTENTION: MAXIMUM LIFTING POWER OF LIFT LINKAGE AT THE SUSPEN-
SION AXIS DETERMINES TECHNICAL OPERABILITY OF THIS LIFT LINKAGE, BUT
NOT THE PERMISSIBLE WEIGHT OF THE IMPLEMENT COUPLED WITH IT. THE
PERMISSIBLE WEIGHT OF THE IMPLEMENT DEPENDS ON THE CENTROID OVER-
HANGING LENGTH IN RELATION TO THE SUSPENSION AXIS, AND IT IS LIMITED BY
PERMISSIBLE LOADS ON THE TRACTOR AND BY THE CONTROLLABILITY CRITE-
RION!
ATTENTION: WHEN OPERATING LIFT LINKAGES, MAKE SURE THAT THIRD
PERSONS ARE AT A SAFE DISTANCE FROM LIFT LINKAGES!

4.3.2 Three-point rear lift linkage

Three-point rear lift linkage of "BELARUS-2022.6" tractor is made according to
State Standard GOST 10677 and ISO 730. Basic parameters of RLL specified in table
4.3.1 and in figures 4.3.1, 4.3.2 are given with rear tires of standard configuration
(580/70R42 both single and twinned) mounted on the tractor and with standard static ra-
dius, specified by the tire manufacturer.
Rear lift linkage consists of three links (upper and two lower links) coupled with the
tractor with front ends by means of hinged joint, and with rear ends with free hinged joints
for connection to the link pins of the implements coupled. RLL is designed for connection
of rear position implements to the tractor, for link power transfer during operation and for
adjustment of their position during operation or movement in transport position. RLL pro-
vides coupling of the following types of implements and machines:
- mounted implement fixed in three points (upper and lower links);
- semi-mounted (lower links);
- semi-mounted with a cross bar to the suspension axis of lower links.
ATTENTION: IT IS ALLOWED TO MOUNT A CROSS BAR OR TRAILING SUS-
PENSION AXIS BEING A PART OF THE IMPLEMENTS KIT TO THE RLL LOWER LINKS
ENDS FOR COUPLING OF SEMI-MOUNTED, SEMI-TRAILED AND TRAILED IMPLE-
MENTS, FOR PERFORMANCE OF DIFFERENT WORK WITH THE TRAVEL SPEED
NOT MORE THAN 15 KM/H!
RLL sizes and design of tractors "BELARUS-2022.6" make it possible to couple all
implements having the corresponding dimensions of the coupling triangle connecting ele-
ments shown in RLL diagram.
Rear lift linkage diagram of type "LL-3" is shown in figure 4.3.1.
Rear lift linkage diagram of type "LL-2" is shown in figure 4.3.2.
RLL design provides the use of a control bar which by way of fixing lower links to-
gether at a specific size, ensures the required length of the suspension axis and makes
their coupling with the machine easy. For the protection of coupled implements from sway-
ing, length adjustable limit external rods are used.
