CONTROLS, INSTRUMENTS
AND
OPERATION--
Pull the Draft Control lever back to the neutral
po-
sition, i.e., when
the
three-point linkage neither
raises nor lowers. Set
the
adjustable stop adjacent
to
it
A WARNING: Draft Control
is
recom-
411a
mended
when
operating Auxiliary
Serv-
ices.
Never
change
from Draft
to
Position Control
while
Auxiliary Services
are
in
use
as
this
may
cause sudden unexpected movement
of
the
imple-
ment and could result
in
injury
to
a bystander.
The A.S.C. valve
is
operated
by
means
of
a knob
installed beneath
the
front
of
the
seat. See Figure
25. Move the knob
to
the mid-position. This will
allow oil to flow
to
the three-point linkage
and
the
remote cylinder together when the Draft Control
lever is
raised above the neutral position.
NOTE: Hydraulic oil will
take
the
path
of
least
resistance, therefore, operation
of
the
three-point
linkage will depend
upon
the
type
of
auxiliary
equipment in
use.
Pull the A.S.C. valve knob fully out (forward)
to
cut off
the
oil supply to the three-point linkage
and
direct the oil to the remote cylinder only.
NOTE: Do not operate
the
trac'tOr
with
the
A.S~C.
valve knob pulled out and
no
cylinder connected
as
this will cause
the
hydraulic system relief valve
to
blow continuously
and
overheat
the
oil.
This
can
also occur
when
a cylinder isfu/.ly extended or
retracted
and
the
control
is
not returned
to
neu-
tral.
To extend the remote cylinder pull the Draft
Con-
trol lever
to
the rear
of
the neutral point. When
fully
extended, return the lift control lever to
the
neutral position to avoid blowing the circuit relief
valve.
Push
the Draft Control lever forward of the
neutral position
to retract the remote cylinder.
A WARNING: Before disconnecting
re-
.a
mote cylinders, ensure
the
implement
24
isfully lowered and
move
the
A.S.C. valve lever
(where
fitted)
fu.lly
rearward
(towards
the seat).
NOTE:
If
the
implement
is
removed
with
the
cyl-
inder extended then oil will
be
lost
from
the rear
axle
housing.
Top
up
the
rear
a:xJe,
if
necessary.
If
the
equipment
is
required
to
give
aposid:ve
hold,
operate
independently
of
the
tractor lift controls
or
where
the
fuli
power
of
the
tractor hydraulic
system
is
required
'tO
operate
remote
cylinders
it
is
recommended that a Ford
remote
control valve
be
used
instead
of
the
auxiliary services control
valve.
Ensure
that oil contained within
the
remote cylin-
ders
is
clean.
has
not
broken
down
due to long
storage
and
is
of
the
correct
grade.
Contaminated
oil within the cylinders will
be
drawn
into the
trac-
'tOr
hydraulic system
when
the
cylinders
are
in
use
and
may
cause early failure
of
transmission or hy-
draulic
components.
