5.15.9 Caster Wheels
Adjusting Caster Tread Width
The rear casters can be adjusted to a narrow tread width, which allows loading and shipping without having to
remove them.
A narrow tread width is better suited for smaller headers because it allows more space to the uncut crop, and provides
more maneuverability around poles, irrigation inlets, and other obstacles.
A wider tread width reduces runover in heavy crops that produce large windrows.
WARNING
To avoid bodily injury or death from unexpected startup of the machine, always stop the engine and remove the key
from the ignition before leaving the operator’s seat for any reason.
CAUTION
Park on a flat, level surface with the header on the ground, the ground speed lever in PARK position, and the steering
wheel in locked position (centered). Wait for the HPT to beep and display a red P symbol to confirm the park brakes
have engaged.
