Three-Point Front Lift Linkage - Belarus 1822.3 Operator's Manual

5.3.3 Three-point front lift linkage

Optionally the tractor "BELARUS-2022.5".may have FLL installed.
Front lift linkage with dimensions corresponding to standard size "LL-2", is similar on critical
parameters to the rear lift linkage. The front lift linkage is designed for the following purposes:
- forming of combined units (tiller is in front of the machine, and seeder is behind and etc.);
- forming of echelon linkage mounting (front and side-cut mower, etc.);
- transportation of individual implements detached from the combined units located in the
rear end during long-distance transportation;
- for mounting of front hanging ballast.
The front lift linkage of a tractor is used with tilling machines only in a propelling condition,
the FLL is not designed for use with tilling machines on reverse.
IT IS PROHIBITED TO OPERATE FLL WITH LOGGING BLADES, AND FOR JACKING OF
TACTOR FRONT ELEMENT.
Note – Rules on coupling of implements with FLL, guidance on changing of FLL operating
position into the transport position, and also the general information about the design of FLL are
set forth in subsection 3.19 "Front lift linkage.
