···,·--
A WARNING: Never operate
the
tractor
4lla
with a loose wheel rim or
disc.
Always
tighten nuts to the specified torque and at
the
rec-
ommended intervals. Owners should
ensure
that
all steering components are maintained
in
a reli-
able
and
satisfactory condition
to
ensure
safe
op-
eration and comply with legal requirements.
A WARNING: A tractor
with
narrow
.a,
wheel settings,
may
not be
as
stable
under
the
same conditions,
as
a tractor with
wide
wheel
settings.
Use
the
maximum width possible which is
compatible with your operation, especially on
rough
·ground, slopes ar across ditches.
A WARNING: Your tractor
is
produced
4lla
with lights that meet lighting regulations
when operating or traveling
o~
the
public
highway.
If
the wheel track setting
is
adjusted
be-
yond the initial factory position then
you
may be
required to reposition the lights or fit auxiliary
lighting
to
comply with legal requirements. Addi-
tionally, before traveling on the highway, ensure
that
the
overall tractor width does not exceed
the
maximum permitted in your country.
POWER ADJUSTED REAR WHEELS
(Option)
Examples
of
power adjusted rear
wheels
are
shown
in
Figures
43
and 44.
Each wheel disc (the centre part
of
the
wheel
as-
sembly) is clamped to rails welded
to
the
rim
to
form
a helix. Movement
of
the clamps
along
the
rail
will
cause the rim
to
move in or out, relative to
the
wheel
disc
which is bolted to the
axle.
One
of
the
clamps
is
positively located by a pair
of
stop lugs screwed into holes in one of
the
rails.
Movement
of
the stop lugs
from
one
hole
to the
38
next will,
when
all
the
clamp bolts have been loos-
ened,
allow
the
wheel disc to rotate relative to the
rim
and
tire to provide
an
alteration
in
track width.
