nector. While changing the implement position from operating to transport, the point of the
implement connection to the tractor remains unchanged. Semi-trailed implements include
various vehicles for general and special purposes: general purpose trailers and semi-
trailers, tank semi-trailers, dump trucks, and special purpose semi-trailed vehicles for
mechanization of technological process in agriculture.

4.3 Lift linkage

4.3.1 General information

While operating front or rear lift linkage with the remote control console (if available), the
operator shall stay beyond the reach of the three-point lift linkage and also consider the
sizes of the uplifted implement projecting parts.
ATTENTION: BEFORE LEAVING THE TRACTOR FOR ANY TIME PERIOD, IT IS RE-
QUIRED TO LOWER THE IMPLEMENT TO THE GROUND!
ATTENTION: MAXIMUM LIFTING POWER OF LIFT LINKAGE AT THE SUSPENSION
AXIS DETERMINES TECHNICAL OPERABILITY OF THIS LIFT LINKAGE, BUT NOT
THE PERMISSIBLE WEIGHT OF THE IMPLEMENT COUPLED WITH IT. THE PERMIS-
SIBLE WEIGHT OF THE IMPLEMENT DEPENDS ON THE CENTROID OVERHANGING
LENGTH IN RELATION TO THE SUSPENSION AXIS, AND IT IS LIMITED BY PERMIS-
SIBLE LOADS ON THE TRACTOR AND BY THE CONTROLLABILITY CRITERION!

4.3.2 Three-point rear lift linkage

Three-point rear lift linkage of "BELARUS-1523.5" tractor is made according to State
Standard GOST 10677 and ISO 730. Basic parameters of RLL specified in table 4.1 and in
figures 4.3.1, 4.3.2 are given with rear tires of standard configuration (520/70R38 both sin-
gle and twinned) mounted on the tractor and with standard static radius, 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 ad-
justment of their position during operation or movement in transport position. RLL provides
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 SUSPENSION
AXIS BEING A PART OF THE IMPLEMENTS KIT TO THE RLL LOWER LINKS ENDS
FOR COUPLING OF SEMI-MOUNTED, SEMI-TRAILED AND TRAILED IMPLEMENTS,
FOR PERFORMANCE OF DIFFERENT WORK WITH THE TRAVEL SPEED NOT MORE
THAN 15 KM/H!
RLL sizes and design of tractors "BELARUS-1523.5" make it possible to couple all imple-
ments having the corresponding dimensions of the coupling triangle connecting elements
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 together at
a specific size, ensures the required length of the suspension axis and makes their cou-
pling with the machine easy. For the protection of coupled implements from swaying,
length adjustable limit external rods are used.
