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

1 . An agricultural implement system, comprising:
a hitch assembly configured to couple to a tow vehicle; a wing tool bar configured to rotate relative to the hitch assembly; a first wing frame pivotally coupled to the wing tool bar, wherein the first wing frame is configured to support a plurality of row units, and the first wing frame is positioned forward of the wing tool bar relative to a direction of travel; and an air cart support arm having a first end and a second end, opposite the first end, wherein the first end of the air cart support arm is pivotally coupled to the wing tool bar, 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, opposite the direction of travel, relative to the hitch assembly in response to rotation of the wing tool bar in the rearward direction.

2 . The agricultural implement system of claim 1 , comprising a pivot joint configured to pivotally couple the first end of the air cart support arm to the wing tool bar.

3 . The agricultural implement system of claim 1 , comprising a second wing frame and 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.

4 . The agricultural implement system of claim 3 , 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.

5 . The agricultural implement system of claim 1 , comprising a wheel assembly coupled to the wing tool bar and configured to support the wing tool bar.

6 . The agricultural implement system of claim 5 , wherein the wheel assembly extends forwardly in the direction of travel relative to the wing tool bar.

7 . The agricultural implement system of claim 5 , comprising a plurality of press wheels coupled to the wing tool bar.

8 . The agricultural implement system of claim 1 , wherein the wing frame comprises at least one triangular section, and the triangular section is configured to rotate relative to the wing tool bar.

9 . An agricultural implement system, comprising:
a hitch assembly configured to couple to a tow vehicle; a center tool bar coupled to the hitch assembly; a wing tool bar pivotally coupled to the center tool bar; a first wing frame pivotally coupled to the wing tool bar, wherein the first wing frame is configured to support a plurality of row units, and the first wing frame is positioned forward of the wing tool bar relative to a direction of travel; and an air cart support arm having a first end and a second end, opposite the first end, wherein the first end of the air cart support arm is pivotally coupled to the wing tool bar, 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, opposite the direction of travel, relative to the center tool bar in response to rotation of the wing tool bar in the rearward direction.

10 . The agricultural implement system of claim 9 , comprising a second wing frame and 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.

11 . The agricultural implement system of claim 10 , 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.

12 . The agricultural implement system of claim 9 , comprising a wheel assembly coupled to the wing tool bar and configured to support the wing tool bar.

13 . The agricultural implement system of claim 12 , wherein the wheel assembly extends forwardly in the direction of travel relative to the wing tool bar.

14 . The agricultural implement system of claim 9 , wherein the wing frame comprises at least one triangular section, and the triangular section is configured to rotate relative to the wing tool bar.

15 . An agricultural implement system, comprising:
a hitch assembly configured to couple to a tow vehicle; a first wing tool bar configured to rotate relative to the hitch assembly; a first wing frame pivotally coupled to the first wing tool bar, wherein the first wing frame is configured to support a first plurality of row units, and the first wing frame is positioned forward of the first wing tool bar relative to a direction of travel; a second wing tool bar configured to rotate relative to the hitch assembly; a second wing frame pivotally coupled to the second wing tool bar, wherein the second wing frame is configured to support a second plurality of row units, and the second wing frame is positioned forward of the second wing tool bar relative to the direction of travel; and a first air cart support arm and a second air cart support arm, wherein each air cart support arm of the first and second air cart support arms has a first end and a second end, opposite the first end, the first end of the first air cart support arm is pivotally coupled to the first wing tool bar, the first end of the second air cart support arm is pivotally coupled to the second wing tool bar, the second end of the first air cart support arm is configured to couple to an air cart, the second end of the second air cart support arm is configured to couple to the air cart, and the first and second air cart support arms are configured to drive the air cart in a rearward direction, opposite the direction of travel, relative to the hitch assembly in response to rotation of the first and second wing tool bars in the reward direction.

16 . The agricultural implement system of claim 15 , comprising a third wing frame, a fourth wing frame, a first telescoping mechanism, and 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.
