Autosteer Safety

The GeoLink Autosteer system provides steering guidance control, when the proper conditions are met, but you are responsible for driving the machine and must remain alert and in complete control of the machine at all times.

When using the control console for assisted steering during spraying operation, ensure that you operate the machine with attention to the following:

  • The control console does not detect obstacles or hazards, keep the machine away from people, animals, buildings, and other structures.

  • Do not operate the machine near high-voltage power lines or other overhead obstacles.

  • Ensure that the operating area is clear of obstacles.

  • Know the position of the machine and the ground (field) conditions at all times.

  • Respond if satellite signals or the RTK correction is lost momentarily.

    Note: When fallback mode is enabled, the system remains engaged if the RTK correction is lost and momentarily drops to float, estimated, or GPS. The system only disengages if the GPS signal is lost. Take manual control if the GPS signal is lost.

Take manual control of the machine if an obstacle appears in the path of the machine or if the machine moves off of the guideline.

Note: The black (or white) icon indicates that guidelock mode is off and the colored icon indicates that it is on.

Using boundary steering

Boundary steering creates a guideline inside the boundary and is offset by half an implement width away from the boundary. The offset width can be adjusted using the nudge menu.

Ensure that the guideline is a sufficient distance away from the boundary to avoid colliding with anything.

As the vehicle moves towards the center of the field, more guidelines are created. Guidelines are spaced one implement width apart.

To create a boundary, refer to your GeoLink Software Guide.

  1. Enable boundary steering in the setup menu.

    g468381
