CenterLine Real-Time Operation
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
<HEADLAND> is displayed. If <HEADLAND> is not displayed in reverse video, press Enter. This
switches the guidance mode to Headland. If <HEADLAND> is displayed in reverse video, the sys-
tem is already in Headland mode.
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 or Curve AB 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 or Curve AB mode while driving
along a straight edge of a field. See the underlined caution under “Curve AB Guidance Operation”
on page 45, when establishing AB guideline for Curve AB operation. For more detail on how to
establish a reference guideline see “Marking A and B Locations” on page 34.
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 34). The reference guideline can
be used for Straight-line and Curve AB 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 36 on page 38 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 37 on page 38 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 41).
Figure 38 on page 39 shows the operator continuing to drive around the second headland circuit.
