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 im-
plement 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”.

6. The lowering speed of the lower
link is proportional to the applied
weight but can be controlled by
adjusting the draining passage of
the hydraulic uid. (See "Lowering
