SECTION 4 –
ENGINE AND DRIVE SYSTEMS
•
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
rows that are running straight up and down.)
The -..-..-..- lines represent the direction that
the front wheels are pointed when the
operator shifts out of AWS speed range. If
this occurs, the rear wheels will shift back to
the straight position and the machine will no
longer have the two tire tracks (two circles).
The rear wheels will begin to follow the -..-..-
..- path during this shift.
Hagie Manufacturing Company once
again strongly recommends trying out and
getting a feel for the AWS System before
going straight to the field so you can get an
understanding of what to expect. Some
situations to try include:
•
Driving the machine with both an empty
and a full solution tank with AWS on.
•
Drive the machine on hills, ensuring to
take the proper precautions as stated in
the
Safety and Precautions Section
else-
where in this manual.
•
Drive the machine at different turn
angles and speeds to see how the limita-
tions work.
NOTE: You will notice that if you go over any
of the limitations, you can slow back
down and the AWS system will
automatically turn itself back on.
•
Auto Steer Machines Only:
Notice how the machine feels when in
AWS mode and switching from Auto
Steer ON to OFF, especially when turn-
ing.
