Abstract

An agricultural system includes a header and a controller. The controller is configured to receive an indication to operate the agricultural system in a non-harvesting mode, output a first signal to set the header in a set profile upon initialization of the non-harvesting mode, receive sensor feedback indicative of an obstacle position of an obstacle relative to the header while the agricultural system operates in the non-harvesting mode, and output a second signal to adjust the header to deviate from the set profile based on the sensor feedback while the agricultural system operates in the non-harvesting mode.

First claim

The invention claimed is:

1. An agricultural system, comprising:
a header; and
a controller configured to:
receive an indication to operate the agricultural system in a non-harvesting mode;
output a first signal to set the header in a set profile upon initialization of the non-harvesting mode;
receive sensor feedback indicative of an obstacle position of an obstacle relative to the header while the agricultural system operates in the non-harvesting mode; and
output a second signal to adjust the header to deviate from the set profile based on the sensor feedback while the agricultural system operates in the non-harvesting mode.

2. The agricultural system of claim 1 , wherein the sensor feedback is indicative that a distance between the obstacle and a portion of the header is below a distance threshold.

3. The agricultural system of claim 1 , wherein the controller is configured to output a third signal to move the header to a non-harvesting position relative to a field upon initialization of the non-harvesting mode, to receive another indication to operate the agricultural system in a harvesting mode, and to output a fourth signal to move the header to a harvesting position relative to the field upon initialization of the harvesting mode, wherein the header is positioned closer to the field while in the harvesting position as compared to in the non-harvesting position.

4. The agricultural system of claim 1 , wherein the header comprises a first section and a second section, and the first signal, the second signal, or both are configured to cause the first section and the second section to move relative to one another.

5. The agricultural system of claim 4 , wherein the sensor feedback is indicative of the obstacle position relative to the second section, and the controller is configured to maintain a section position of the first section and the second signal is configured to cause the second section to move relative to the first section in response to receiving the sensor feedback.

6. The agricultural system of claim 4 , comprising an actuator coupling the first section to the second section, wherein the second signal instructs the actuator to move the first section and the second section relative to one another.

7. The agricultural system of claim 1 , comprising a sensor communicatively coupled to the controller and configured to transmit the sensor feedback to the controller, wherein the sensor is a contact sensor, a non-contact proximity sensor, or both.

8. A non-transitory computer readable medium comprising executable instructions that, when executed by a processor, are configured to cause the processor to:
operate an agricultural system in a harvesting mode;
receive an indication to operate the agricultural system in a non-harvesting mode;
output a first signal to raise a header of the agricultural system relative to a field and relative to a harvesting position of the header in the harvesting mode in response to receiving the indication to operate the agricultural system in the non-harvesting mode;
output a second signal to orient the header based on a set profile upon initialization of the non-harvesting mode;
receive sensor feedback indicative of an obstacle position of an obstacle relative to the header while the agricultural system operates in the non-harvesting mode; and
output a third signal to set a header position of the header based on the sensor feedback while the agricultural system operates in the non-harvesting mode, wherein the header position is different from the set profile.

9. The non-transitory computer readable medium of claim 8 , wherein the instructions, when executed by the processor, are configured to cause the processor to:
determine a distance between the obstacle and a section of the header is below a distance threshold based on the sensor feedback; and
output the third signal to adjust the section of the header such that the distance between the obstacle and the section of the header is at or above the distance threshold.

10. The non-transitory computer readable medium of claim 9 , wherein the instructions, when executed by the processor, are configured to cause the processor to:
determine the distance between the obstacle and the section of the header is above the distance threshold based on the sensor feedback; and
output a fourth signal to adjust the section of the header to return toward the set profile in response to the distance between the obstacle and the section of the header being above the distance threshold.

11. The non-transitory computer readable medium of claim 8 , wherein the indication to operate the agricultural system in the non-harvesting mode is received from a user input, from sensor feedback, or both.

12. The non-transitory computer readable medium of claim 8 , wherein the instructions, when executed by the processor, are configured to cause the processor to:
receive an additional indication to operate the agricultural system in the harvesting mode; and
output a fourth signal to lower the header relative to the field and relative to a non-harvesting position of the header in the non-harvesting mode in response to receiving the additional indication to operate the agricultural system in the harvesting mode.

13. The non-transitory computer readable medium of claim 12 , wherein the instructions, when executed by the processor, are configured to cause the processor to output the third signal to set the header position of the header based on the sensor feedback by raising the header, lowering the header, tilting the header, or any combination thereof.

14. An agricultural system, comprising:
a header comprising a first section and a second section; and
a controller configured to:
operate the agricultural system in a harvesting mode or a non-harvesting mode:
output a first signal to position the header at a harvesting position that enables the header to harvest a field in the harvesting mode;
output a second signal to set a first position of the first section and a second position of the second section based on a set profile upon initialization of the non-harvesting mode;
receive sensor feedback indicative of an obstacle position of an obstacle relative to the header in the non-harvesting mode; and
output a third signal to adjust the first section, the second section, or both based on the sensor feedback in the non-harvesting mode.

15. The agricultural system of claim 14 , wherein the set profile comprises a non-harvesting position, and the non-harvesting position is raised relative to the field as compared to the harvesting position.

16. The agricultural system of claim 14 , wherein the set profile comprises a leveled configuration of the first section relative to the second section.

17. The agricultural system of claim 14 , wherein the second section extends from the first section, and the agricultural system comprises a third section extending from the first section opposite the second section.

18. The agricultural system of claim 17 , wherein the controller is configured to output a fourth signal to adjust a third position of the third section relative to the first section, and the third signal and the fourth signal are output independently of one another.

19. The agricultural system of claim 14 , wherein the controller is configured to transition between operating the agricultural system in the harvesting mode and operating the agricultural system in the non-harvesting mode in response to receiving an indication.
