Abstract

An agricultural implement system including a hitch assembly configured to couple to a tow vehicle, a plurality of wing tool bars coupled transversely to the hitch assembly, and a plurality of wing frames pivotally coupled to the plurality of wing tool bars Each wing frame is configured to support a plurality of row units and is positioned forward of a respective wing tool bar. The agricultural implement system further includes an air cart support arm with a first and second end. The first end of the air cart support arm is pivotally coupled to the wing tool bar and the second end of the air cart support arm is configured to couple to an air cart and the air cart support arm is configured to drive the air cart in a rearward direction relative to the hitch assembly in response to rotation of the wing tool bar in the rearward direction.

First claim

The invention claimed is:

1. An agricultural implement system, comprising:
a center frame comprising a center bar;
a first wing frame comprising a wing bar, wherein the first wing frame is configured to rotate about a vertical axis relative to the center frame;
a second wing frame;
a telescoping mechanism;
wherein the telescoping mechanism is configured to couple the first and second wing frames to one another and to selectively enable articulation of the second wing frame relative to the first wing frame while the first and second wing frames are in a raised transport position; and
a locking mechanism configured to lock the center bar to the wing bar, and the locking mechanism is configured to unlock the center bar from the wing bar to facilitate rotation of the first wing frame about the vertical axis relative to the center frame.

2. The agricultural implement system of claim 1 , wherein the telescoping mechanism is configured to block articulation of the second wing frame relative to the first wing frame in response to insertion of a pin into an insertion point on the first wing frame, and to facilitate articulation in response to removal of the pin from the insertion point on the first wing frame.

3. The agricultural implement system of claim 1 , wherein the center frame is configured to remain in the working position while the first wing frame is rotated upwardly.

4. The agricultural implement system of claim 1 , wherein the locking mechanism is configured to lock the center bar to the wing bar by a U-connector.

5. The agricultural implement system of claim 4 , wherein the locking mechanism is configured to unlock the center bar from the wing bar in response to upward rotation of the first wing frame.

6. The agricultural implement system of claim 4 , wherein the locking mechanism is configured to automatically lock when the first wing frame rotates downwardly.

7. The agricultural implement system of claim 1 , wherein the locking mechanism is configured to automatically unlock when the first wing frame rotates upwardly.

8. An agricultural implement system, comprising:
a center frame comprising a center bar;
a first wing frame comprising a first wing bar, wherein the first wing frame is configured to rotate about a vertical axis relative to the center frame;
a second wing frame comprising a second wing bar, wherein the second wing frame is configured to rotate about a vertical axis relative to the center frame, and wherein the first wing frame and second wing frame are disposed on opposite lateral sides of the center frame;
a third wing frame;
a fourth wing frame;
a first telescoping mechanism;
a second telescoping mechanism;
wherein the first telescoping mechanism is configured to couple the first and third wing frames to one another and to selectively enable articulation of the third wing frame relative to the first wing frame while the first and third wing frames are in a raised transport position; and
wherein the telescoping mechanism is configured to couple the second and fourth wing frames to one another and to selectively enable articulation of the fourth wing frame relative to the second wing frame while the second and fourth wing frames are in a raised transport position;
a first locking mechanism that is configured to lock the center bar to the first wing bar, and the first locking mechanism is configured to unlock the center bar from the first wing bar to facilitate rotation of the first wing frame about the vertical axis relative to the center frame; and
a second locking mechanism that is configured to lock the center bar to the second wing bar, and the second locking mechanism is configured to unlock the center bar from the second wing bar to facilitate rotation of the second wing frame about the vertical axis relative to the center frame.

9. The agricultural implement system of claim 8 , wherein the first telescoping mechanism is configured to block articulation of the third wing frame relative to the first wing frame in response to insertion of a first pin into a first insertion point on the first wing frame, and to facilitate articulation in response to removal of the first pin from the first insertion point on the first wing frame; and
wherein the second telescoping mechanism is configured to block articulation of the fourth wing frame relative to the second wing frame in response to insertion of a second pin into a second insertion point on the second wing frame, and to facilitate articulation in response to removal of the second pin from the second insertion point on the second wing frame.

10. The agricultural implement system of claim 8 , wherein the center frame is configured to remain in the working position when the first or the second wing frame is rotated upwardly.

11. The agricultural implement system of claim 8 , wherein both the first and second locking mechanisms are configured to lock the center bar to the respective wing bar by a U-connector.

12. The agricultural implement system of claim 8 , wherein both the first and second locking mechanisms are configured to automatically unlock when the respective wing frame rotates upwardly.

13. An agricultural implement system, comprising:
a center frame comprising a center bar;
a first wing frame comprising a wing bar, wherein the first wing frame is configured to rotate about a vertical axis relative to the center frame;
a second wing frame;
a telescoping mechanism;
wherein the telescoping mechanism is configured to couple the first and second wing frames to one another and to selectively enable articulation of the second wing frame relative to the first wing frame while the first and second wing frames are in a raised transport position; and
a locking mechanism configured to lock the center bar to the wing bar, and the locking mechanism is configured to unlock the center bar from the wing bar to facilitate rotation of the first wing frame about the vertical axis relative to the center frame, and wherein the center bar is the most forward lateral bar of the center frame relative to the direction of travel, and the wing bar is the most forward lateral bar of the first wing frame relative to the direction of travel.

14. The agricultural implement system of claim 13 , wherein the telescoping mechanism is configured to block articulation of the second wing frame relative to the first wing frame in response to insertion of a pin into an insertion point on the first wing frame, and to facilitate articulation in response to removal of the pin from the insertion point on the first wing frame.

15. The agricultural implement system of claim 13 , wherein the center frame is configured to remain in the working position when the first wing frame is rotated upwardly.

16. The agricultural implement system of claim 13 , wherein the locking mechanism is configured to lock the center bar to the wing bar by a U-connector.

17. The agricultural implement system of claim 16 , wherein the locking mechanism is configured to automatically unlock when the first wing frame rotates upwardly.
