Abstract

A forming shield arrangement configured for a windrowing work vehicle is supported for movement by a support structure. The forming shield arrangement is configured to at least partly shape a windrow of a crop material. A method of operating the forming shield arrangement includes receiving, by a processor of a control system from a memory element, a stored position setting that corresponds to a position of the forming shield arrangement relative to the support structure. The method also includes processing, by the processor, a positioning control signal based, at least in part, on the stored position setting. Moreover, the method includes changing, with an actuator, the position of the forming shield arrangement according to the positioning control signal.

First claim

What is claimed is:

1. A method of operating a forming shield arrangement that is configured for a windrowing work vehicle, the forming shield arrangement including at least one forming shield that is moveably supported by a support structure, the at least one forming shield including a deflecting surface that extends substantially in a vertical direction, the deflecting surface configured to deflect a crop material for forming a windrow, the method comprising:
receiving, by a processor of a control system from a memory element, a stored position setting that corresponds to a position of the deflecting surface relative to the support structure;
receiving, by the processor, one or more of weather data and crop data that corresponds to a characteristic of the crop material windrowed with the at least one forming shield;
processing, by the processor, a positioning control signal based, at least in part, on the stored position setting and one or more of the weather data and the crop data; and
moving, with an actuator, the at least one forming shield relative to the support structure according to the positioning control signal to change the position of the deflecting surface.

2. The method of claim 1 , wherein the at least one forming shield includes a first forming shield with a first deflecting surface and a second forming shield with a second deflecting surface, the first and second forming shields being disposed on opposite sides of the forming shield arrangement; and
wherein moving the at least one forming shield includes moving the first forming shield and the second forming shield according to the positioning control signal.

3. The method of claim 1 , wherein the support structure supports the at least one forming shield for rotation about a substantially vertical axis; and
wherein moving the at least one forming shield includes rotating, with the actuator, the at least one forming shield about the substantially vertical axis according to the positioning control signal.

4. The method of claim 1 , further comprising detecting, with a sensor, an actual position setting of the at least one forming shield and saving the actual position setting as the stored position setting.

5. The method of claim 4 , wherein detecting the actual position setting occurs during a first harvesting operation within a field; and
wherein receiving the stored position setting, processing the positioning control signal, and moving the at least one forming shield occur during a second harvesting operation within the field, the second harvesting operation being subsequent to the first harvesting operation.

6. The method of claim 4 , further comprising receiving, by the processor, location data that corresponds to an actual location of the windrowing work vehicle within a field; and
wherein processing the positioning control signal includes processing the positioning control signal based, at least in part, on the stored position setting and the location data.

7. The method of claim 6 , further comprising performing a first harvesting operation in the field with the windrowing work vehicle and performing a second harvesting operation in the field with the windrowing work vehicle;
wherein performing the first harvesting operation includes:
detecting the actual position setting of the at least one forming shield;
detecting an actual location of the windrowing work vehicle within the field where the at least one forming shield is at the actual position setting;
saving, within the memory element, the actual position setting as the stored position setting with the detected actual location associated therewith; and
wherein performing the second harvesting operation includes:
receiving, by the processor from the memory element, the stored position setting and the associated actual location;
determining, by the processor, that the second harvesting operation includes return travel to the actual location;
processing the positioning control signal based, at least in part, on the stored position setting and the associated actual location; and
moving the at least one forming shield according to the positioning control signal.

8. The method of claim 1 , further comprising outputting, via a user interface, a user message corresponding to the stored position setting.

9. The method of claim 8 , wherein the user message is a user query whether to move the at least one forming shield according to the stored position setting; and
wherein moving the at least one forming shield occurs as a result of a user confirmation to move the at least one forming shield according to the stored position setting.

10. A windrowing work vehicle that defines a vertical direction comprising:
a support structure;
a forming shield arrangement with at least one forming shield that is supported for movement on the windrowing work vehicle by the support structure, the at least one forming shield including a deflecting surface that extends substantially in the vertical direction, the deflecting surface configured to deflect a crop material for forming a windrow;
a control system with a processor and a memory element; and
an actuator configured to actuate the at least one forming shield to change a position of the deflecting surface relative to the support structure;
the processor being configured to receive, from the memory element, a stored position setting that corresponds to the position of the deflecting surface;
the processor being configured to process a positioning control signal based, at least in part, on the stored position setting and one or more of weather data and crop data that corresponds to a characteristic of the crop material windrowed with the at least one forming shield; and
the actuator configured to actuate to change the position of the deflecting surface according to the positioning control signal.

11. The windrowing work vehicle of claim 10 , wherein the at least one forming shield includes a first forming shield with a first deflecting surface and a second forming shield with a second deflecting surface, the first and second forming shields being disposed on opposite sides of the windrowing work vehicle; and
wherein the actuator is configured to actuate to move the first forming shield and the second forming shield according to the positioning control signal.

12. The windrowing work vehicle of claim 10 , wherein the support structure supports the at least one forming shield for rotation about a substantially vertical axis; and
wherein moving the at least one forming shield includes rotating, with the actuator, the at least one forming shield according to the positioning control signal.

13. The windrowing work vehicle of claim 10 , further comprising a sensor that is configured to detect an actual position setting of the at least one forming shield; and
wherein the memory element is configured to store the detected actual position setting as the stored position setting.

14. The windrowing work vehicle of claim 13 , further comprising a location sensor that is configured to detect an actual location of the windrowing work vehicle within a field;
wherein the memory element is configured to store actual location data that corresponds to the actual location detected by the location sensor;
wherein the processor is configured to associate within the memory element, the actual location data with the stored position setting; and
wherein the processor is configured to process the positioning control signal based, at least in part, on the stored position setting and the associated actual location data.
