How does the AgGPS Parallel Swathing Option lightbar indicate off track error?
The AgGPS Parallel Swathing lightbar contains a row of LEDs (lights). The center LED represents the swath line. The LEDs to the left and right of center represent a user defined ground distance. For example, the operator may configure a 6 inch (0.15 m) LED sensitivity. In this example, the first led to the left of center represents six inches to the left of the swath line. The second LED to the left of center represents 1 ft (0.3m), the third LED 1 ft 6 in. (0.45m) and so on, to the end of the lightbar. When exactly on line, the center three LEDs illuminate. As the operator drives to the left of the swath line, the illumination band moves from the center LED toward the left edge of the lightbar. The operator steers to bring the illuminated LEDs back to center. .
