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 the ground when it is moving
across the ground. This is called
as"oating".

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 4-44)
