Three-Point Front Lift Linkage - Belarus 2022.6 Operator's Manual

4.3.4 Three-point front lift linkage

Front lift linkage (FLL) is mounted on tractor "BELARUS-2022.6" against order.
Tractor with FLL is completed with front independent PTO, mounted on the front
plane of bracket 4 (figure 4.3.9).
FLL is mounted on the front plane of beam 3 and is fixed with additional plates 2 to
the beam side surface.
In the lower part of FLL bracket 4 there are two ears to which two buckles 11 are at-
tached. Other ends of turn buckles are locked into two brackets 1 which are mounted onto
amplifying plates. HPH 10 connect section No.2 of the hydraulic lift linkage distributor (fig-
ure 2.19.2) with lift linkage hydraulic cylinders 7. Hydraulic cylinders of double action are
fixed to bracket 4 from the one side, and with the help of a rod they are connected to lower
links unit 8 mounted on the shaft in bracket 4 lower part. Upper link 5 is fixed to the upper
part of FLL bracket 4 with the help of a pin.

cylinder; 8 – lower links unit; 9 – cotter; 10 – high pressure hose (HPH); 11 – buckle
FLL is designed for tractor operation as part of combined assemblies and serves for
coupling mounted agricultural implements of category 2, located in front of the tractor, to
the tractor.
FLL is designed for the following purposes:
- formation of combined assemblies (cultivator – in front, seeder – at the back,
etc.);
- formation of echelon linkages (front and side mowing machines, etc.);
- transportation of separate machines from the structure of combined assemblies
of rear location while long-distance moving.
With FLL mounted, front ballast weights are mounted onto FLL links, as shown in
subsection 4.6 "Front ballast".
Tractor FLL is used with tillage machines only in a pushing mode – FLL use with
tillage machines on reverse is not provided.
