Abstract

A windrowing work vehicle with a swath flap arrangement is disclosed. The swath flap arrangement includes a swath flap that is supported for movement by a support structure between a raised position and a lowered position. The swath flap is configured to at least partially shape a windrow of a crop material. A method includes receiving, by a processor of a control system from a memory element, a stored position setting that corresponds to a position of the swath flap relative to the support structure. The method further includes processing, by the processor, a positioning control signal based, at least in part, on the stored position setting. Also, the method includes moving, with an actuator, the swath flap relative to the support structure between the raised position and the lowered position according to the positioning control signal.

First claim

What is claimed is:

1. A method of operating a swath flap arrangement configured for a windrowing work vehicle, the swath flap arrangement including a swath flap that is supported for movement by a support structure between a raised position and a lowered position, the swath flap configured to at least partially shape a windrow of a crop material, 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 swath flap relative to the support structure;
processing, by the processor, a positioning control signal based, at least in part, on the stored position setting;
moving, with an actuator, the swath flap relative to the support structure between the raised position and the lowered position according to the positioning control signal; and
detecting, with a sensor, an actual position setting of the swath flap and saving the actual position setting as the stored position setting.

2. The method of claim 1 , wherein moving the swath flap includes rotating the swath flap about an axis of rotation that extends laterally across the windrowing work vehicle.

3. The method of claim 1 , wherein detecting the actual position setting occurs during a first harvesting operation; and
wherein receiving the stored position setting, processing the positioning control signal, and moving the swath flap occur during a second harvesting operation, the second harvesting operation being subsequent to the first harvesting operation.

4. The method of claim 1 , further comprising receiving, by the processor, location data that corresponds to an actual location of the windrowing work vehicle within a field;
further comprising associating, within the memory element, the location data with the stored position setting; 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 associated location data.

5. The method of claim 4 , 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 swath flap;
detecting an actual location of the windrowing work vehicle within the field where the swath flap 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
changing the position of the swath flap according to the positioning control signal.

6. The method of claim 1 , further comprising receiving, by the processor, weather data; 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 weather data.

7. The method of claim 1 , further comprising receiving, by the processor, crop data that corresponds to a characteristic of the crop material that is windrowed with the swath flap at the actual position setting;
wherein processing the positioning control signal includes processing the positioning control signal based, at least in part, on the stored position setting and the crop data.

8. The method of claim 1 , wherein receiving the stored position setting includes receiving a stored baseline setting for the position of the swath flap;
wherein processing the positioning control signal includes processing the positioning control signal based on the baseline setting;
further comprising detecting a manual adjustment to the position of the swath flap after moving the swath flap according to the baseline setting; and
saving, in the memory element, an update to the baseline setting according to the manual adjustment.

9. A method of operating a swath flap arrangement configured for a windrowing work vehicle, the swath flap arrangement including a swath flap that is supported for movement by a support structure between a raised position and a lowered position, the swath flap configured to at least partially shape a windrow of a crop material, 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 swath flap relative to the support structure;
processing, by the processor, a positioning control signal based, at least in part, on the stored position setting;
moving, with an actuator, the swath flap relative to the support structure between the raised position and the lowered position according to the positioning control signal; and
outputting, via a user interface, a user message corresponding to the stored position setting.

10. The method of claim 9 , wherein the user message is a user query whether to move the swath flap according to the stored position setting; and
wherein changing the position occurs as a result of a user confirmation to change the swath flap according to the stored position setting.

11. A windrowing work vehicle comprising:
a support structure;
a swath flap that is supported for substantially vertical movement on the windrowing work vehicle by the support structure, the swath flap configured to form a windrow of a crop material;
a control system with a processor and a memory element; and
an actuator configured to actuate the swath flap to change a position of the swath flap arrangement 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 swath flap;
the processor being configured to process a positioning control signal based, at least in part, on the stored position setting;
the actuator configured to actuate to change the position of the swath flap according to the positioning control signal; and
a sensor that is configured to detect an actual position setting of the swath flap;
wherein the memory element is configured to save the detected actual position setting as the stored position setting.

12. The windrowing work vehicle of claim 11 , wherein the actuator is configured to rotate the swath flap about an axis of rotation that extends laterally across the windrowing work vehicle.

13. The windrowing work vehicle of claim 11 , 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.

14. The windrowing work vehicle of claim 13 , wherein the location sensor is in communication with a global positioning system for detecting an actual geolocation of the windrowing work vehicle.
