C.
Adjusting lever
As shown
in
Fig. 22,
the
adjusting lever can be used
at
three
positions.
The
adjusting lever regulates
the
oil flow;
that
is,
when
an implement
is
heavy,
the
oil flow
is
reduced,
and
when light,
the
oil flow
is
increased, thereby, controlling
the
lowering speed of an
implement.

The
position A
is
used when
an
implement
is
requested quick
lowering such as plow. etc.
The
position B
is
used when
the
P.T.O.
is
in use. Particularly, it
is
the
most
suitable when the rotary tiller with rotating blades starts
to
cultivate with
the
minimum shock.
The
position C
is
used for locking the oil returning from
the
ram
cylinder, thereby, lock lowering
of
the
lift arm.
It
is
also usable
as
a .safety device when
the
tractor
moves for hours with an
implement
or
when it
is
serviced
with
an implement mounted.
D.
External Hydraulic Valve {Optional Equipment)
The
external hydraulic valve
is
operated
by
the
control lever. A
special valve
is
provided in order
to
allow
the
oil
to
flow from the
ram cylinder
to
the
cylinder
of
an implement.
E.
Note on hydraulic
oil replacement.
When replacing
the
hydraulic oil,
re-
move
the
strainer
as
shown
in
Fig.
23
and clean it.
Then
feed
the
oil.
