OPERATION
4.3.7 Ad justi
ng Caster Tread Width
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
manoeuvrability around poles, irriga tio n inlets, or other obstacles.
A wider tread width is useful in heavy crops that produce large windrows so that runover is reduced.
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.
CAUTION

evel surface, header on the ground, and the ground speed lever in N-DETENT position and
steering whe
el locked.
Adjust the caster tread width as follows:
1. 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 at (B).
NOTE:

least 5000 l
b (2270 kg).
2. Remove six
bolts (A) four on backside, two on
underside
