Abstract

A tillage machine includes a main frame, a gang rotatably coupled to the main frame, and an arcuately-shaped adjustment rail coupled to the main frame. At least a portion of the adjustment rail is spaced from the main frame. The adjustment rail includes a plurality of apertures each configured to receive a locking structure, and the adjustment rail defines an open space adjacent the main frame.

First claim

What is claimed is:

1. A tillage machine comprising:
a main frame;
a gang rotatably coupled to the main frame; and
an arcuately-shaped adjustment rail coupled to the main frame, wherein at least a portion of the adjustment rail is spaced from the main frame, wherein the adjustment rail includes a plurality of apertures each configured to receive a locking structure, wherein the gang includes a roller in contact with the adjustment rail, and wherein the adjustment rail defines an open space adjacent the main frame.

2. The tillage machine of claim 1 , wherein the adjustment rail has a thickness when viewed directly from above when the tillage machine is on a level ground or field, wherein the thickness is less than 3 inches.

3. The tillage machine of claim 1 , wherein the gang includes a plurality of blades, wherein the gang is rotatably coupled to the main frame about a pivot point on the main frame, and wherein the adjustment rail extends along a radius of curvature that extends from the pivot point.

4. The tillage machine of claim 1 , wherein a first bracket is coupled to the main frame and a second bracket is coupled to the main frame, wherein the adjustment rail extends between the first and second brackets.

5. The tillage machine of claim 4 , further comprising an actuator coupled to the second bracket, wherein the actuator is a linear actuator configured to move the gang.

6. The tillage machine of claim 5 , wherein the linear actuator is rotatably coupled to the second bracket.

7. The tillage machine of claim 5 , wherein the gang includes a third bracket, and wherein the linear actuator is a hydraulic cylinder that includes a cylinder rod pressed against the third bracket of the gang.

8. The tillage machine of claim 1 , further comprising the locking structure, wherein the locking structure is a spring-biased pin configured to lock an angular position of the gang.

9. The tillage machine of claim 8 , wherein the gang includes a main plate, and wherein the locking structure is coupled to the main plate.

10. A gang for a tillage machine, the gang comprising:
a gang support element;
a plurality of blades rotatably coupled to the gang support element;
a bracket extending from the gang support element, wherein the bracket includes a main plate having an aperture;
a roller coupled to the main plate; and
a locking structure coupled to the main plate, wherein the locking structure includes a pin configured to extend through the aperture.

11. The gang of claim 10 , wherein the roller is a first roller, wherein the gang includes a second roller coupled to the main plate.

12. The gang of claim 10 , wherein the bracket includes a first plate extending from the main plate, a second plate extending from the main plate, and a third plate extending between the first and second plates.

13. The gang of claim 12 , wherein first and second plates each extend perpendicularly from the main plate, and wherein the third plate extends parallel to the main plate.

14. The gang of claim 10 , wherein the pin is a spring-biased pin.

15. A tillage machine comprising:
a main frame;
an arcuately-shaped adjustment rail coupled to the main frame, the adjustment rail including a plurality of apertures and an upper surface; and a
a gang coupled to the main frame about a pivot point, the gang including a gang support element, a plurality of blades rotatably coupled to the gang support element, and a roller coupled to the gang support element and in contact with the upper surface.

16. The tillage machine of claim 15 , further comprising a locking structure having a handle and a main pin body, wherein the main pin body is configured to be extended in and out of the plurality of apertures.

17. The tillage machine of claim 16 , wherein the gang includes a bracket coupled to the gang support element, wherein the bracket includes a main plate, wherein the locking structure is coupled to the main plate and includes a biasing element that biases the main pin body toward the adjustment rail.

18. The tillage machine of claim 15 , wherein the upper surface defines a thickness of the adjustment rail, wherein the thickness is less than 1 inch.

19. The tillage machine of claim 15 , wherein the adjustment rail extends along a radius of curvature that extends from the pivot point.
