(1) Lower Link
6. The lowering speed of the lower
link is proportional to the applied
weight but can be controlled by ad-
justing the draining passage of the
hydraulic fluid. (See "Lifting arm
speed control knob" on Page 4-25)

1. The position control lever is used
to lift or lower the lifting arm (lower
link) of the 3-point hitch.
2. Pushing the lever forward lowers
the lower link while pulling the le-
ver backward lifts the lower link.
3. The height of the lower link is pre-
cisely controlled proportional to the
position of the lever.
4. The lower link is lifted by the hy
-
draulic energy of the tractor while
it is lowered by potential energy
of its own weight. Therefore, the
implement cannot be lowered by
the hydraulic pressure.
5. Therefore, the implement attached
to the lower link may be lifted by
protrusion on the ground when it is
lowered to the ground. It is called
as "oating."
