Abstract

A system for adjusting the alignment of ground engaging tools of an agricultural implement may include a first toolbar configured to support a first plurality of tools aligned along a first tool axis, and a second toolbar configured to support a second plurality of tools aligned along a second tool axis. The second toolbar may be movable relative to the first toolbar between a first toolbar position and a second toolbar position such that the second tool axis is movable relative to the first tool axis. The system may additionally include an actuator configured to actuate the second toolbar between the first toolbar position, where the first and second tool axes are substantially coincident, and the second toolbar position, where the second tool axis is substantially spaced apart from the first tool axis.

First claim

What is claimed is:

1. A system for adjusting the alignment of ground engaging tools of an agricultural implement, the system comprising:
a first toolbar configured to support a first plurality of tools, the first plurality of tools being aligned along a first tool axis;
a second toolbar configured to support a second plurality of tools, the second plurality of tools being aligned along a second tool axis, the second toolbar being movable relative to the first toolbar between a first toolbar position and a second toolbar position such that the second tool axis is movable relative to the first tool axis, a portion of at least one tool of the second plurality of tools being positioned axially between an adjacent pair of tools of the first plurality of tools when the second toolbar is in the first toolbar position; and
an actuator configured to actuate the second toolbar between the first and second toolbar positions,
wherein, when the second toolbar is in the first toolbar position, the second tool axis is positioned at a first distance relative to the first tool axis, and
wherein, when the second toolbar is in the second toolbar position, the second tool axis is spaced apart from the first tool axis by a second distance, the second distance being greater than the first distance.

2. The system of claim 1 , wherein, when the second toolbar is in the first toolbar position, each tool of the second plurality of tools is positioned axially between a respective pair of adjacent tools of the first plurality of tools such that the first and second pluralities of tools are provided in an alternating arrangement along the first tool axis.

3. The system of claim 1 , wherein the second toolbar defines a rotational axis extending along a length of the toolbar,
wherein the actuator comprises a rotary actuator configured to pivot the second toolbar about the rotational axis between the first and second toolbar positions.

4. The system of claim 1 , wherein the first and second toolbar positions are spaced apart longitudinally from each other such that the actuator is configured to move the second toolbar longitudinally between the first and second toolbar positions.

5. The system of claim 1 , wherein the first and second toolbar positions are spaced apart vertically from each other such that the actuator is configured to move the second toolbar vertically between the first and second toolbar positions.

6. The system of claim 1 , further comprising a controller configured to adjust the alignment of the first and second pluralities of tools by controlling an operation of the actuator to actuate the second toolbar between the first and second toolbar positions.

7. The system of claim 6 , wherein the controller is further configured to receive an input indicative of excessive material accumulation relative to at least one adjacent pair of tools of the first and second pluralities of tools, the controller being configured to control the operation of the actuator upon receipt of the input to actuate the second toolbar between the first and second toolbar positions.

8. The system of claim 1 , wherein the first and second pluralities of tools comprise first and second pluralities of disk blades, respectively, the first plurality of disk blades being rotatable about the first tool axis and the second plurality of disk blades being rotatable about the second tool axis.

9. The system of claim 8 , wherein, when the second toolbar is in the first toolbar position, the first distance is equal to or less than a radius of the first plurality of disk blades.

10. The system of claim 1 , wherein the first and second tool axes are coaxially aligned when the second toolbar is in the first toolbar position such that the first distance is equal to zero.

11. The system of claim 1 , wherein the first toolbar is positioned forward of the second toolbar along a direction of travel of the implement.

12. An agricultural implement, comprising:
a frame;
a first toolbar supported by the frame member, the first toolbar being configured to support a first plurality of disk blades, the first plurality of disk blades being rotatable about a first tool axis;
a second toolbar supported by the frame member, the second toolbar being configured to support a second plurality of disk blades, the second plurality of disk blades being rotatable about a second tool axis, the second toolbar being movable relative to the first toolbar between a first toolbar position and a second toolbar position such that the second tool axis is movable relative to the first tool axis,
wherein, when the second toolbar is in the first toolbar position, the second tool axis is positioned at a first distance relative to the first tool axis, the first distance being less than or equal to a radius of the first plurality of disk blades, and
wherein, when the second toolbar is in the second toolbar position, the second tool axis is spaced apart from the first tool axis by a second distance, the second distance being greater than the first distance.

13. The agricultural implement of claim 12 , further comprising an actuator configured to actuate the second toolbar between the first and second toolbar positions.

14. The agricultural implement of claim 13 , wherein the actuator is configured to at least one of pivot the second toolbar between the first and second toolbar positions, move the second toolbar vertically between the first and second toolbar positions, or move the second toolbar laterally between the first and second toolbar positions.

15. The agricultural implement of claim 13 , further comprising a controller configured to adjust the alignment of the first and second pluralities of disk blades by controlling an operation of the actuator to actuate the second toolbar between the first and second toolbar positions.

16. A method for adjusting the alignment of ground engaging tools of an agricultural implement, the agricultural implement comprising a first toolbar configured to support a first plurality of tools, the first plurality of tools being aligned along a first tool axis, the agricultural implement further comprising a second toolbar configured to support a second plurality of tools, the second plurality of tools being aligned along a second tool axis, the method comprising:
receiving, with a computing device, an input associated with adjusting the alignment between the first plurality of tools and the second plurality of tools; and
controlling, with the computing device, an operation of an actuator based on the received input to actuate the second toolbar relative to the first toolbar from a first toolbar position, where the second tool axis is positioned at a first distance relative to the first tool axis, the first distance being less than or equal to a predetermined spacing distance, to a second toolbar position, where the second tool axis is spaced apart from the first tool axis by a second distance, the second distance being greater than the first distance,
wherein a portion of at least one tool of the second plurality of tools is positioned axially between an adjacent pair of tools of the first plurality of tools when the second toolbar is in the first toolbar position.

17. The method of claim 16 , further comprising controlling, with the computing device, the operation of the actuator to actuate the second toolbar relative to the first toolbar back to the first toolbar position.

18. The method of claim 16 , wherein the input is associated with adjusting the alignment between the first plurality of tools and the second p
