CONTROLS, INSTRUMENTS
AND
OPERATION--
11.Four Wheel Drive Axle
1.
Axle breather
The front
axle
assembly incorporates a limited
slip differential for improved traction
and
stabil-
ity.
The
limited slip differential
is
fully automatic,
unobtrusive in operation
and
requires
no
action on
the
pan
of
the operator.
When
cleaning the tractor, particularly if using a
hose, avoid directing the water jct directly
at
the
breather located on top
of
the
axle.
Sec
Figure
11.
Water entering the axle may cause severe damage
to
driveline components.
NOTE:
To
avoid undue tire
wear
when
travelling
on
the
public highway or
any
hard
surface,
it
is
recommended
that four
wheel
drive
be
disen-
gaged.
A WARNING:
Tractors
with/our
wheel
4lla
drive
engaged or
disengaged
should
not
be allowed
to
exceed 25
mph
(40
kph).
Over-
speeding
by
towing
or
coasting
downhill
with
clutch
depressed or transmission
in
neutral
may
cause
loss
of
control, personal
injury
or failure
of
the
drive
shaft.
Keep
the
tractor
in
the
same
gear
going
downhill
as
would be

BREAKING-IN
PROCEDURE
Your
new
Ford tractor will provide long
and
de-
pendable service
if
given proper care during
the
50 hour breaking-in period
and
if
serviced at the
recommended intervals.
Avoid
prolonged operation at either high or low
engine speeds without a load on
the
engine.
Avoid
overloading
the
engine. Operating in
too
high
a gear under heavy load may cause
exce~ive
engine overloading. Overloading occun when
the
engine will not
respond
to a throtde
increase.
Use
the lower gear ratios
when
pulling heavy
loads
and
avoid continuous operation at constant
engine speeds. Operating
the tractor in
too
low
a
gear
with
a light load and high engine speed will
waste
fuel. You will save
fuel
and
minimise en-
gine wear
by selecting the correct gear ratio for
each particular operation.
Check
the
instruments frequently and keep the
ra-
diator
and
various
oil
reservoirs filled
to
the
rec-
ommended
levels.
