4WD Alarm
The 4WD Warning Alarm is located in the Leveling
System Control Monitor. It will sound an alarm, a warning
light will flash and 4WD Alarm will be displayed on the
monitor if the combine is traversing down a slope that is
greater than 20% and the 4WD is engaged. Disengage
the 4WD and the warning will be cleared. On downhill
slopes less than 20%, level ground or uphill slopes the
warning will not come up if 4WD is engaged.
See your combine's Operator's Manual to understand
how to operate the Rear Wheel Assist (RWA).
