INSTALLATION
Step 1:
GPS antenna
a. Mount the antenna on the
highest part of the vehicle.
Ensure that there are no
obstructions in the way of
the GPS antenna.
b. Mount the antenna along the
boom centerline as shown
below.
Note – Ensure that the
vehicle with the GPS
antenna on top can safety fit
through the door of the
machine shed!

lightbar. Mount the lightbar for
comfortable viewing inside
the cab.
Note – The lightbar can be
mounted upside down.To flip
the text, change the MOUNT
setting to CEILING.
b. Mount the remote keypad for
comfortable access.

SWATH PATTERN OPTIONS
The following table lists the swath pattern options and describes the approach LED colors and operation.
Pattern Tips on using this pattern Diagram
NEW A-B
NEW A+
NEWCURVE
To set a straight guidance line, set new A
and B points.
If you have set area points, this area is
used for headland approach LED color.
Use A+ pattern for irregular gaps in your
field, or for adjacent parallel fields. Just
reset Point A to generate a new reference
line that is perfectly parallel to the last A-B
line.
With this pattern, if you have set area
points, this area is used for headland
approach LED color . If y ou d o not ha v e any
area points, then you do not get any
approach LED indication.
This option is only available if there is a
valid A-B Line still in memory.
To set a curved guidance line, set new A
and B points.
The approach LED does not indicate the
start and end of the curve swaths.
However , when you are approaching a turn,
end LEDs appear as a turn signal.
Snap to Swath is not available with the
Curve pattern. You must manually
increment the swath. Before beginning your
turn, you must press –/+.

NEWHLND
For straight parallel swaths inside the
headland, map at least one headland pass
around the outside of the field and then set
A and B points.
Before you can set the A and B points, you
must complete the headland.
When you approach the he adland, the
approach LED indicates your distance to
the end of the swath.
Note – EZ-Guide only calculates field area
based on area points, not headlands.

GUIDANCE
To obtain guidance in a field, define a reference swath by mapping A and B points. The lightbar then provides
guidance at swath-width intervals. To get guidance:
Step 1:
Clear guidance
a. At the start of the
new field, clear old
guidance points by
pressing:
b. To select the desired pattern
option, press:
c. When the lightbar displays the
desired option, press:
Note – With a curve pattern, the lightbar LEDs and text only provide cross-track error (XTE) guidance parallel to the last swath.
When you get past the end of each swath, they display the distance to the end of the swath.
+
• Diagrams in the SWATH PATTERN
OPTIONS section on the previous page
show which keys to press for each
pattern option.
Approach indication
The large, central LED indicates where you are in relation to the swath line:
• GREEN – inside the spray zone. Turn the boom on when the LED turns green.
• RED – outside the spray zone. Turn the boom off when the LED turns red.
For more information, see the diagrams in the SWATH PATTERN OPTIONS section on the previous page.
If the HLNDWARN value is configured to greater than 0, the approach LED turns ORANGE to indicate your
approach to the spray zone boundary (from either direction). Prepare to turn the boom on or off.
Step 2:
Map the guidance line
Step 3:
Follow the lightbar
a. T urn left or right for the next sw ath. If the
next swath is not automatically selected
or the wrong swath is selected, press
–/+.
b. Steer your vehi cle so that you center
the green lights in the middle of the
lightbar and drive forward down the
swath.
Pausing guidance
You can pause guidance, for example, to refill chemical tanks or refuel.
To pause guidance … To resume guidance …
While in mid-swath, press . Press again.

corner of the field and press:
Each time the key is pressed, a new area value
is displayed. The area is calculated from the outside
end of the application boom.
Note – A minimum of three area points are required to
calculate the field area. The maximum number of area
points is 99.
The following diagram shows mapped area points and the
area calculated.

Tip – Acreage calculations take the current swath width
into account, so you should drive a half-swath in from the
field edge.
ALARMS
If the alarm is connected, it sounds at various times during a swathing operation to indicate that you are:
• entering or leaving the spray zone (as defined by the A-B end-zone, or by a defined headlands area)
• drifting too far off-swath (use the
• returning to the current swath while guidance is paused
• losing differential corrections (use the
