The Circle Pivot Pattern Option
This section describes how to run swath guidance when the Circle Pivot guidance pattern option is selected. The Cir-
cle Pivot option is selected when the operator wants to apply product in a center pivot field while being guided along
a circular guideline that matches the center pivot radius.
The Circle Pivot mode operates very similar to the Parallel mode. The operator marks an A point, drives along the arc
that the pivot would create, a wheel track is a good guide, then marks a B point. Once the B point is marked, a circular
guideline appears on the SmartPad screen and the operator is guided along this circular guideline. As the operator
completes one circular pass and moves in either direction (left or right) to the next guideline, the software automati-
cally creates the next circular guideline.
Marking Point A
In this example the operator wants to apply product to a portion of a field that has a center pivot on it. The operator
drives around this portion creating a headland. While driving parallel to an existing wheel track the operator marks
the initial A point. Figure 3-66 shows the operator beginning to drive the along the center pivot perimeter. The opera-
tor has not pressed the Mark A button yet and is notified on the lightbar to do so. Figure 3-67 shows the vehicle
beginning to drive along the existing wheel track and marking point A. In this example the operator has elected to
drive a single headland pass. This is not necessary, the operator could have driven along the wheel track and marked
points A and B and then started driving back and forth moving towards or away from the center of the pivot.
