Operation and Conclusion |

Autoguide switch on Command Arm in the cab |
During operation, the PA reads an imbalance of light between it's two sensors and
commands the servo to rotate the pots. The tractor then turns right or left,
depending on which steering indicator LED is illuminated. If the GPS
unit does not illuminate a right or left LED, the PA automatically centers the
servo therefore, the steering pots. Pictured above is the switch we installed in the Command Arm in the cab. When the switch is turned ON, the PA steers the tractor according to it's light readings. When the switch is OFF, the PA is powered and keeps the servo in the centered position. During operation, use of the system is pretty much as has been explained. One nice feature is the there is no need for any kind of re-engagement of auto steering after turning around at the headlands. Basically, as the operator completes the turn and the GPS unit guides them with it's steering indicator lights, as the lights come closer to center and within range of the sensors the Autosteer system simply starts steering as it thinks it should. In total we think we spent about $200 and 30 hours on this system (besides the Outback S and the tractor itself). Much thanks to our local John Deere dealership, Greenvalley Equipment for their willingness to share information about the tractor. |
