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 PERION, 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!

5.3.2 Three-Point Rear Lift Linkage

Basic parameters of RLL, specified in Table 5.1 and in Figures 5.3.1, 5.3.2, are given with
rear tires 650/75R42 both single and doubled, mounted to the tractor and with standard
static radius, specified by the manufacturer.
ATTENTION: FOR GENERAL USE LIFT LINKAGE OF LL-4 TYPE IS RECOM-
MENDED!
Rear lift linkage as defined by subsection 3.18 "Rear lift linkage", consists of three
drawbars (upper one and two lower drawbars) 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. RLL is designed for connec-
tion of implements for tail positioning to a tractor, for drawbar power transfer during opera-
tion and adjustment of their position during operation, or run at transport position. RLL pro-
vides for coupling of the following types of implements and instruments:
- mounted implement fixed in three points (upper one and lower drawbars);
- semimounted (lower drawbars);
- semimounted with a cross arm to the suspension axis of lower drawbars (when mount-
ing of LL "LL-3").
ATTENTION: MOUNTING OF A CROSS ARM 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 DRAW-
BARS OF REAR LIFT LINKAGE!
There is a possibility of completing a tractor with several standard sizes and ver-
sions of lift linkages.
Sizes and structure of RLL of tractors "BELARUS-3522.5" make it possible to cou-
ple all implements, having the corresponding dimensions of attachment elements of con-
nection 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-4" is shown in Figure 5.3.2.
