How
to
release
the
differential lock:
Immediately after
the
right
foot
is
moved
off
the
pedal,
the
differential
lock
is
automatically released by force of
the
spring. However, it must
be remembered
that
the
lock may
not
be released
under
special
conditions.
In
this case,
the
right and left brake pedals should be
quickly
and
alternatively depressed, then,
the
differential lock
will
be
set free.
If
the
same occurs while plowing,
the
brake pedal
of
the
land
wheel side should be applied.
The
lock will be let out. When
the
both
right and left brakes are linked for towing a trailer, operation of
the
steering handle
to
right and left allows
the
lock becoming free. When
the
tractor
is
stopped with
the
differential lock applied, reverse running
with a jerk can release
the
lock.
Note: Avoid using
the
differential lock when operating
the
tractor
at
high speed
or
running
on
a road.
12. P.T.O. OPERATION
The
P.T.O. shaft speed
is
as shown in Fig. 12.
When
the
P.T.O. driven implement
is
used,
the
following instructions
should be observed:
P.T.O shaft speed
1092 r.p.m.
540
r.p.m.
(engine
2800 r.p.m.)

T.O. Lever Position
A.
When
any
implement
is
mounted on
the
tractor, care should be
taken
so
that
the
universal
joint
will
not
form
an
angle more
than
the
limit (normally 15°).
B.
When
the
P.T.O.
is
under an impact load, correctly adjust the slide
clutch
on
the
implement side so
that
no
over load will
be
given.
C.
To
reduce
the
thrust
load
to
the
P.T.O. driven
shaft
as maximum as
possible, it
is
advisable
that
the
test
operation with an implement
but
without
any load
is
requested.
D.
Thoroughly apply lubricants
to
the
P.T.O. driven shaft.
E.
Avoid using a square-shaped driven
shaft
as much as possible.
F.
Special care should be given
to
the yoke position so
that
the
driven
shaft
is
well balanced.
