Headland Guidance Operation
This section describes how to operate CenterLine in the Headland guidance mode. The Headland
mode is used when the operator wants to drive several circuits around the field boundary and be
guided around all circuits that occur after the first. When several headland circuits have been com-
pleted, the operator has the option of switching to the Straight-line mode. The Headland pattern is
also used when a user wants to do product application on terraced fields. In the Headland curved
guidance pattern, the operator can pull along side any previous applied swath and be guided par-
allel to that swath by the X-Track guidance display.
To select the Headland guidance mode, scroll with Up or Down in the real-time menu until
or is displayed on the lightbar. If is displayed then
Headland mode is already active. If is displayed, press Enter. This switches the
guidance mode from Straight-Line to Headland.
NOTE: When the display shows , it is asking if you want to switch to Headland mode
from Straight-Line. When the display shows , it is asking if you want to switch to
Straight-Line mode from Headland.
Reference Guideline
While operating in the Headland mode, the user has the option to mark the A and B points of the
reference guideline used in the Straight-line Guidance mode. This feature makes it easier for the
operator to Mark the A and B points while in Headland mode applying the headlands. It is always
best to mark the A and B points for the Straight-line mode while driving along a straight edge of a
field. For more detail on how to establish a reference guideline see —Marking A and B Locations“
on page 30.
The operator remains in the Headland mode until the guidance mode is changed using the real-
time menu (see —Switching between Guidance Modes“ on page 31). The reference guideline is
only required for the Straight-line mode.
Headland Pattern Example
In this example the operator wants to apply two headland passes to the field and then switch to
Straight-line mode and apply the remainder of the field with straight-line parallel swath guidance.
After the first headland circuit the operator pulls parallel to the first circuit swath and begins apply-
ing the second circuit while being guided parallel to the first circuit.
Figure 34 on page 35 shows the operator just finishing the first headland circuit. When the opera-
tor pulls along side the first headland circuit, curved guidance automatically starts. The operator is
now able to drive the second headland circuit parallel to the first circuit by following the guidance
information displayed on the lightbar.
Figure 35 on page 36 shows the operator being guided along side the initial headland circuit. The
lightbar automatically supplies guidance information. For more details on how to interpret curved
guidance information on the lightbar (See —Headland Mode Lightbar Graphics“ on page 38).
Figure 36 on page 36 shows the operator continuing to drive around the second headland circuit.
