3.19 Front lift linkage

3.19.1 General information

The front lift linkage is installed on the tractor against order.
The front lift linkage is intended for operation of the tractor with complex units and
serves for coupling the tractor with mounted agricultural machines, located in front of the
tractor, and also for installation of ballast weights.
The tractor with FLL is equipped with a continuous power takeoff shaft, that is
mounted on a front plane of a bracket 4 (figure 3.19.1).
The FLL is mounted on a front plane of a beam 3 and is attached with additional
plates 2 to the side beam surface. In a lower part of the bracket 4 of the FLL there are two
eyelets to which two turnbuckles 11 are attached. The other ends of the turnbuckles are
attached to two brackets 1, which are mounted on strengthening strips. High-pressure
hoses 10 connect one section of the valve group, located behind the tractor cab, with hy-
draulic cylinders 7 of the lift linkage. The double-action hydraulic cylinders are attached to
the bracket 4 on the one end, and their rods are connected to a lower link unit 8, mounted
on a shaft in the lower part of the bracket 4. The upper link 5 is attached to the upper part
of the FLL bracket 4 with a pin.
