OPERATION
To stop the windrower:
1. SLOWLY return the ground speed lever (GSL) (A) to
NEUTRAL and into N-DETENT.
2. Turn steering wheel until it locks.
3. Move throttle lever (B) to low idle position
NOTE: Avoid unnecessary idling. Stop engine if
it will be idling for longer than 5 minutes.
4. Brakes are automatically engaged when steering
wheel is locked in NEUTRAL position.
IMPORTANT:
Before stopping engine, run at low idle for
approximately 5 minutes to cool hot engine parts
(and allow turbocharger to slow down while
engine oil pressure is available).
5. Turn ignition key counterclockwise to OFF position.

4.3.7 Adjusting 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, irrigation inlets, or other obstacles.
A wider tread width is useful in heavy crops that produce large windrows so that runover is reduced.
CAUTION
Park on a flat, level surface, header on the ground, and the ground speed lever in N-DETENT position and
steering wheel locked.
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.
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: Lifting device should have a lifting
capacity of at least 5000 lb (2270 kg).
2. Remove six bolts (A) four on backside, two on
underside, and washers from left and right side of
walking beam.
