When the control lever is set to the "Down" position,
the spool (4) moves to the left.
The oil forced from the P port flows through the gap
between the control valve body and the spool to the
T1
port.
The oil
in the hydraulic cylinder flows through the gap
between the control valve body (3) and the spool (4) to
the T2 port.
Since the oil
in the hydraulic cylinder drains to the
transmission case, the implement lowers.
Since the spool shape
is step down structure, oil pass
slowly from C port through the gap between the control
valve body (3) and the spool (4) to T2 port.
In this tractor, when setting the control lever to the
"Slow
down" position, implement lowers down with ease
in increments
of approximately 1/4 inches at lower link
end.
