SECTION 4 –
ENGINE AND DRIVE SYSTEMS
4-17
When conditions are met again, AWS will
automatically activate and the AWS indicator
will illuminate.
NOTE: The machine will automatically
determine if the proper conditions
have been met and change the
status of the drive functions.
1. Ensure the machine’s drive state is in
Field mode.
2. Press the AWS Button (located on the
Machine Display Home Page - Field
Mode) to the ON (illuminated) position.
An AWS indicator (located below the
speedometer) will illuminate when AWS is
activated (requiring all conditions to be met).
Shut off Speed for AWS
Refer to “Machine Display” provided in the
Cab Section
elsewhere in this manual for
further information.
Limitations
•
Machine speed is greater than AWS
shut-off speed.
NOTE: There is no warning message
associated with this. The machine
will automatically switch to
conventional steering mode.
•
The machine’s drive state must be in
Field Mode. If the machine is in Road
Mode, AWS is disabled (and the rear cyl-
inder lock valves are locked).
•
System Fault - The system is not work-
ing properly (e.g. sensor malfunction,
hydraulic malfunction, etc.)
NOTE: A warning message will appear on
the Machine Display and the
machine may be limited on speed
and other functions.
•
Auto Steer Machines Only
:
When the Auto Steer System is
engaged, it will automatically turn the
AWS System OFF and move the rear
wheels back to straight.
Recommendations for Best
Operating Practices
•
Apply the Decel Pedal (located to the
lower right-hand side of the steering col-
umn) to decrease speed at end rows.
NOTE: The Decel Pedal is NOT a brake! It is
designated for speed reduction only.
•
Speed ranges are selected by pressing
the Shift Up/Down Switches (located on
the Hydrostatic Drive Control Handle) to
control speed ranges within the vehicle
speed settings.
•
Use the Hydrostatic Drive Control Han-
dle to slow down more if needed. If you
move the Hydrostatic Drive Control Han-
dle first and then shift down to get to
AWS mode, you will notice that the
machine may slow down more than you
wanted it to.
•
Understand how the machine feels when
it is still in a turn and is shifted up or
down. The machine will still operate at
whatever turn angle that you want to
shift out at, but you may feel that this sit-
uation is causing an operation that you
may not want (possibly getting the
machine off the line intended because
the rear wheels move back to straight
position and the total turning radius will
change).
In the following illustration, the two circles
represent a full turn with AWS on. The - - - -
lines represent the direction the operator
wants the front tracks to go (assuming the
operator wants to pull the machine back into
