Abstract

An agricultural system includes a corn head with an end divider and an actuator that moves the end divider between a raised position and a retracted position. An actuator controller receives an input and automatically controls the actuator to move the end divider to a position based upon the input.

First claim

What is claimed is:

1. An agricultural system comprising:
a head configured to be mounted to an agricultural harvester;
a first end divider, movable between a retracted position and a raised position, on a first end of the head;
a first actuator, mounted on the head, configured to move the first end divider between the retracted position and the raised position;
a sensor configured to detect an at least one end divider position criterion and generate a criterion signal based on the detected at least one end divider position criterion, wherein the at least one end divider position criterion comprises at least one of: (i) a geographic position of the agricultural harvester and a map feature; (ii) a crop ear lost over the first end of the head; (iii) a terrain feature of terrain proximate the agricultural harvester; (iv) a mode of the agricultural harvester, the mode indicative of whether the agricultural harvester is in a road mode or a field mode; (v) a crop state of crop adjacent to the agricultural harvester, the crop state indicative of whether crop adjacent to the agricultural harvester is harvested or unharvested; or (vi) a direction of travel of the agricultural harvester;
an actuator controller configured to process the criterion signal to identify a commanded end divider position corresponding to the first end divider; and
a control signal generation system configured to automatically generate a control signal to control the first actuator to move the first end divider to the identified commanded end divider position corresponding to the first end divider.

2. The agricultural system of claim 1 and further comprising:
a second end divider, movable between a retracted position and a raised position, on a second end of the head; and
a second actuator configured to move the second end divider between the retracted position and the raised position, wherein the actuator controller is configured to process the criterion signal to further identify a commanded end divider position corresponding to the second end divider, and
wherein the control signal generation system is configured to automatically generate a control signal to control the second actuator to move the second end divider to the identified commanded end divider position corresponding to the second end divider.

3. A method of controlling an end divider on a head of an agricultural harvester, the method comprising:
detecting an at least one end divider position criterion corresponding to a first end divider on a first end of the head, the first end divider movable between a retracted position and a raised position, wherein detecting the at least one end divider position criterion comprises detecting at least one of: (i) a geographic position of the agricultural harvester and a map feature; (ii) a crop ear lost over the first end of the head; (iii) a terrain feature of terrain proximate the agricultural harvester; (iv) a mode of the agricultural harvester, the mode indicative of whether the agricultural harvester is in a road mode or a field mode; (v) a crop state of crop adjacent to the agricultural harvester, the crop state indicative of whether crop adjacent to the agricultural harvester is harvested or unharvested; or (vi) a direction of travel of the agricultural harvester;
generating a criterion signal based on the detected at least one end divider position criterion;
processing the criterion signal to identify a commanded end divider position corresponding to the first end divider; and
automatically generating a control signal to control a first actuator to move the first end divider to the identified commanded end divider position corresponding to the first end divider.

4. An agricultural machine comprising:
a head configured to be mounted on an agricultural harvester;
a first end divider, movable between a retracted position and a raised position, on a first end of the head;
a first actuator, mounted on the head, configured to move the first end divider between the retracted position and the raised position;
a sensor configured to detect an at least one end divider position criterion and generate a criterion signal based on the detected at least one end divider position criterion, wherein the at least one end divider position criterion comprising at least one of: (i) a geographic position of the agricultural harvester and a map feature; (ii) a crop ear lost over the first end of the head; (iii) a terrain feature of terrain proximate the agricultural harvester; (iv) a mode of the agricultural harvester, the mode indicative of whether the agricultural harvester is in a road mode or a field mode; (v) a crop state of crop adjacent to the agricultural harvester, the crop state indicative of whether crop adjacent to the agricultural harvester is harvested or unharvested; or (vi) a direction of travel of the agricultural harvester; and
a controller configured to process the criterion signal to identify a commanded end divider position corresponding to the first end divider and to automatically generate a control signal to control the first actuator to move the first end divider to the identified commanded end divider position corresponding to the first end divider.
