Raven RGL 600 - Pivot Swathing for Circular Fields

39
PIVOT SWATHING
The Pivot Pattern provides a circular swathing of fields that have a well-defined center and
are shaped like a circle or a section of a circle. The requirement for circular swathing usually
results from use of a pivot irrigation system.
There are two steps in using the Pivot Pattern:
1. Determine the center of the circular pattern.
2. Follow circular swath lines to cover the required area.
Once the center is determined, the Smarbar lays out swath numbers starting at number one
(closest to the center) and increasing outward from the center. To determine the center, the
operator marks points while driving any circular swath. These points mark the Pivot Refer-
ence Circle. The Pivot Minimum Radius (SWA-PMR) is a configuration distance used only
by the Pivot Pattern. The Pivot Reference Circle, the Swath Width (SWW), and PMR
determine the position of circular swath #1. Subsequent swaths are numbered outward from
swath #1 and are located at Swath Width intervals.
