Step 5. Re-Position Caster Wheels (Bolted Frame) - MacDon M105 Assembly Instructions Manual

STEP 5. RE-POSITION CASTER
WHEELS (BOLTED
FRAME)
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.
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 a lifting
capacity of at least 5000 lb (2270 kg).

b. Remove six bolts (four on backside, two on
underside) and washers from left and right side
of walking beam.
c. Slide extensions outboard equal amounts, and
align holes at desired location.
