H61O523A
(1) Lower Link
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."
(1) Lowering Speed Control Lever
(A) High speed (B) Low Speed
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
speed control valve of lifting arm
“lower link” on Page 4-24.)

7. The lower limit of the implement’
s height can be set by limiting the
movement of the control lever by
the lock bolt.
