Abstract

A lift and rotate style agricultural implement with forward folding wings is provided. The agricultural implement includes a center frame that may be operatively configured to be lifted and rotated approximately 90 degrees when switching between a field configuration and a transport configuration. Furthermore, the wings may include an inner portion and an outer portion, wherein the outer portion may be operatively configured to be rotated or pivoted approximately 180 degrees relative to the inner wing portion when switching between a field configuration and a transport configuration. The inner and outer wing portions may be connected by a hinge and the outer wing may be pivoted about the inner wing portion by a cylinder.

First claim

What is claimed is:

1. An agricultural implement comprising:
a tongue comprising a first end and a second end;
a center toolbar at the second end of the tongue;
one or more wings pivotally coupled to the center toolbar, said one or more wings comprising an outer hinge, said outer hinge oriented to allow rotation about a substantially vertical axis and configured to pivot a segment of the one or more wings relative to the center toolbar about said substantially vertical axis; and
a center pivot post operatively attached to the center toolbar, said center pivot post configured to lift the center toolbar and rotate the center toolbar about a generally vertical axis;
wherein the agricultural implement includes a transport configuration wherein the segment has been pivoted towards the one or more wings and the center toolbar has been lifted and rotated such that the segment of the one or more wings, the center toolbar, the tongue, and a direction of travel are substantially parallel with one another.

2. The agricultural implement of claim 1 , wherein the one or more wings further comprising an inner wing section and an outer wing section coupled by said outer hinge, said inner wing section configured to rotate about a substantially horizontal axis relative to the center toolbar during a planting configuration and said outer wing section configured to rotate about a substantially vertical axis relative to the inner wing section to move the implement towards the transport configuration.

3. The agricultural implement of claim 1 , further comprising a plurality of ground engaging tools operatively attached to the center toolbar and the one or more wings.

4. The agricultural implement of claim 3 , wherein the plurality of ground engaging tools operatively attached to the center toolbar comprise row units.

5. The agricultural implement of claim 3 , further comprising a mounting assembly operatively attached to the one or more wings and the center toolbar, said mounting assembly comprising a plurality of attachment points configured to operatively attach the plurality of ground engaging tools along the one more wings and the center toolbar, said plurality of attachment points configured to provide a predefined spacing between adjacent ground engaging tools.

6. The agricultural implement of claim 1 , wherein the agricultural implement includes a planting configuration and a transport configuration, wherein in said planting configuration the one or more wings generally perpendicular to said tongue, and in said transport configuration said one or more wings generally parallel to said tongue.

7. The agricultural implement of claim 6 , wherein the center toolbar is rotated approximately 90 degrees relative to the tongue.

8. The agricultural implement of claim 6 , wherein said center pivot post is configured to lift and rotate the center toolbar to switch between the planting configuration and the transport configuration.

9. The agricultural implement of claim 1 , further comprising a pivot for coupling the one or more wings to the center toolbar, said pivot configured to rotate the one or more wings relative to the center toolbar about a generally horizontal axis.

10. The agricultural implement of claim 9 , further comprising a wing flex apparatus operatively attached proximate to the pivot coupling the one or more wings to the center toolbar, said wing flex apparatus configured to attach one of the plurality of ground engaging tools proximate to the pivot.

11. The agricultural implement of claim 1 , wherein the tongue is a telescoping tongue.

12. An agricultural implement comprising:
a tongue comprising a first end and a second end;
a center toolbar at the second end of the tongue;
one or more wings pivotally coupled to the center toolbar, said one or more wings comprising a hinge configured to pivot a segment of the one or more wings relative to the center toolbar about a substantially vertical axis;
a center pivot post operatively attached to the center toolbar, said center pivot post configured to lift the center toolbar and rotate the center toolbar about a generally vertical axis; and
a wing flex apparatus operatively attached proximate to the pivot coupling the one or more wings to the center toolbar, said wing flex apparatus configured to attach one of the plurality of ground engaging tools proximate to the pivot;
wherein the wing flex apparatus comprises one or more slotted tracks configured to limit the angular rotation of the ground engaging tool operatively engaged by the flex apparatus, said angular rotation of the ground engaging tool operatively engaged by the flex apparatus is less than the angular rotation of an adjacent ground engaging tool attached to the one or more wings.

13. A pivoting frame comprising:
a center toolbar;
one or more wings pivotally coupled to the center toolbar by an inner hinge configured to pivot the one or more wings relative to the center toolbar about a substantially horizontal axis when in a planting configuration;
wherein said one or more wings comprises an inner section and an outer section coupled by an outer hinge, said outer hinge oriented to allow rotation about a substantially vertical axis and configured to pivot the outer section relative to the inner section about said substantially vertical axis when moving towards and from a transport configuration; and
a center pivot post operatively attached to the center toolbar, said center post configured to lift and rotate the center toolbar;
wherein the agricultural implement includes a transport configuration wherein the outer section has been pivoted relative to the inner section and the center toolbar has been lifted and rotated such that the outer section of the one or more wings, the center toolbar, the tongue, and a direction of travel are substantially parallel with one another.

14. An agricultural implement comprising:
a telescoping tongue comprising a first end and a second end, said first end comprising a hitch configured to be attached to a tow vehicle;
a center toolbar attached to the second end of the tongue;
one or more wings pivotally coupled to the center toolbar by an inner hinge, said inner hinge oriented to allow rotation about a substantially vertical axis and configured to pivot the one or more wings relative to the center toolbar about a substantially horizontal axis when in a planting configuration;
wherein said one or more wings comprises an inner section and an outer section coupled by an outer hinge configured to pivot the outer section relative to the inner section about a substantially vertical axis when moving towards and from a transport configuration;
a plurality of ground engaging tools operatively attached along the center toolbar and the one or more wings, said plurality of ground engaging tools adjacent to one another; and
a center pivot post operatively attached to the center toolbar, said center post configured to lift and rotate the center toolbar;
wherein in the transport configuration, the outer section has been pivoted relative to the inner section and the center toolbar has been lifted and rotated such that the outer section of the one or more wings, the center toolbar, the tongue, and a direction of travel are substantially parallel with one another.

15. The agricultural implement of claim 14 , further comprising an actuator pivotally connected at a first end at the outer hinge, and at a second end at the outer section of the one or more wings.

16. The agricultural implement of claim 15 , wherein extension of the actuator extends the inner and outer sections
