Circle track allows operator to create concentric circle guidance lines. It is designed to be used in fields with a center pivot.
A circle track is based on latitude and longitude coordinates at center of a pivot. Concentric guidance lines are created based on track spacing out to 1.6 km (1 mi.) from center of pivot.
There are two methods to create a circle track:
|
Drive Circle |
|
|
Lat/Lon Circle |

Circle track is designed for center pivot operation on ground with less than 2% slope. Since circle track creates circle spacing on a level plane, guidance line spacing and center pivot track do not match as tracks get farther away from center pivot in sloped conditions. This spacing is due to difference between distance traveled on a hill and on a level plane. The difference in distance increases as slope increases.
Use shift track to move tracks radially closer or further from center point. Shift track does not move center point. Shift track allows operator to use various implement widths, account for different lengths of center pivot towers, or to account for stretching or shrinking of center pivot irrigation sections.
If a circle track edge is added, modified or deleted, existing shifts for that track are deleted. Using shift track with an edge causes the implement not to align with the edge.
Distance from center of circle to current location. The distance only shows to 1609 m (5280 ft.).
Feature must be turned on in circle track settings to show button on guidance map.

Once button is on guidance map, select button to show or hide distance. |

Edge represents outer boundary of a center pivot. It is displayed as an orange line on guidance map.
Creating a circle track edge allows guidance lines to be generated starting from edge. Otherwise, guidance lines are generated starting from center of pivot. When guidance lines are created, end of implement will line up against the edge.
Since the edge becomes the reference point, instead of the circle center, guidance lines are generated based on the edge using track spacing and shifts. This can be useful if implements with different track spacings are used in the same field. Just enter a new track spacing, and guidance lines are adjusted starting at the edge.
