WINDROWER OPERATION
169304 57 Rev. C
6.3.7 Adjustable Caster Tread Width
(Optional)
As an option, the rear casters can be adjusted to
a narrow tread width to allow loading and
shipping without having to remove them. A
narrow tread width also suits smaller headers by
allowing more space to the uncut crop and
provides more maneuverability around poles,
irrigation inlets, or other obstacles. A wider
tread width is useful in heavy crops that produce
large windrows so that run-over is reduced.
To adjust the caster tread width, refer to the
following illustrations and proceed as follows:
CAUTION
Park on a flat, level surface, header on the
ground and the ground speed lever in N-
DETENT position.
DANGER
Stop engine and remove key from ignition
before leaving operator's seat for any
reason. A child or even a pet could engage
an idling machine.
a. Raise rear of windrower slightly so that most of
the weight is off the casters, using a jack or
other lifting device under the frame where
shown.
NOTE
Lifting device should have lifting capacity
of at least 5000 lb (2270 kg).
b. Remove bolts and washers (A) and (B) from left
and right sides of the walking beam.
c. Slide walking beam extensions (C) inboard or
outboard equal amounts and align holes at
desired position.
NOTE
Illustration shows widest tread width
adjustment.
IMPORTANT
Center of tread width must be aligned with
center of windrower.
d. Position bracket (D) and install bolts (A) and (B).
The two shorter bolts are installed at the back
inboard locations. Torque as follows:
1. Snug bottom bolts (B).
2. Tighten back bolts (A) to 330 ft·lbf (447
N·m).
3. Tighten bottom bolts (B) to 330 ft·lbf (447
N·m).
e. Lower windrower and remove lifting device.
f. Retorque bolts at 5 and 10 hours of operation.
