Abstract

An agricultural machine includes a center section having a first aperture, a wheel supporting the center section, a wing section connected to the center section and having a second aperture, and a hinge positioned between the center section and the wing section to permit the wing section to pivot about the center section. The hinge includes a pin having a first end and a second end. The pin extends through the first and second apertures to connect the wing section to the center section. A first fastener engages the center section or the wing section and is adjacent to the first end of the pin to thereby retain the pin in the first and second apertures. A second fastener engages the center section or the wing section and is adjacent to the second end of the pin to thereby retain the pin in the first and second apertures.

First claim

What is claimed is:

1. An agricultural machine comprising:
a center section;
a wheel supporting the center section;
a wing section coupled to the center section; and
a hinge positioned between the center section and the wing section to permit the wing section to pivot about the center section, the hinge comprising
a first part including a first protrusion defining a first aperture extending therethrough, the first part coupled to the center section,
a second part including a second protrusion, the second protrusion defining a second aperture extending therethrough, the second part coupled to the wing section,
a pin having a first end and a second end, the pin positioned to extend through the first and second apertures to couple the first part and the second part such that the wing section is pivotably coupled to the center section,
a first fastener positioned adjacent the first end of the pin, the first fastener operable to couple the first part to the center section and to abut the first end of the pin to thereby retain the pin in the first and second apertures, and
a second fastener positioned adjacent the second end of the pin, the second fastener operable to couple the first part to the center section and to abut the second end of the pin to thereby retain the pin in the first and second apertures.

2. The agricultural machine of claim 1 , wherein the first fastener comprises a first bolt, a first nut, and a first bushing, the first bushing positioned adjacent to the first end of the pin.

3. The agricultural machine of claim 2 , wherein the second fastener comprises a second bolt, a second nut, and a second bushing, the second bushing positioned adjacent to the second end of the pin.

4. The agricultural machine of claim 3 , wherein the first part further comprises a third protrusion and a third aperture, the pin extending through the third aperture.

5. The agricultural machine of claim 3 , wherein the second part further comprises a third protrusion and a third aperture, the pin extending through the third aperture.

6. The agricultural machine of claim 1 , wherein the wing section is a first wing section and the hinge is a first hinge, the agricultural machine further comprising a second wing section coupled to the center section and a second hinge positioned between the center section and the second wing section to permit the second wing section to pivot about the center section.

7. An agricultural machine comprising:
a center section defining a first aperture;
a wheel supporting the center section;
a wing section coupled to the center section, the wing section defining a second aperture; and
a hinge positioned between the center section and the wing section to permit the wing section to pivot about the center section, the hinge comprising
a pin having a first end and a second end, the pin positioned to extend through the first and second apertures to pivotably couple the wing section to the center section,
a first fastener engaging one of the center section and the wing section and positioned adjacent the first end of the pin to thereby retain the pin in the first and second apertures, and
a second fastener engaging one of the center section and the wing section and positioned adjacent the second end of the pin to thereby retain the pin in the first and second apertures.

8. The agricultural machine of claim 7 , wherein the first fastener comprises a first bolt, a first nut, and a first bushing, the first bushing positioned adjacent to the first end of the pin.

9. The agricultural machine of claim 8 , wherein the second fastener comprises a second bolt, a second nut, and a second bushing, the second bushing positioned adjacent to the second end of the pin.

10. The agricultural machine of claim 9 , wherein the center section further comprises a third aperture, the pin extending through the third aperture.

11. The agricultural machine of claim 9 , wherein the wing section further comprises a third aperture, the pin extending through the third aperture.

12. The agricultural machine of claim 7 , wherein the wing section is a first wing section and the hinge is a first hinge, the agricultural machine further comprising a second wing section coupled to the center section and a second hinge positioned between the center section and the second wing section to permit the second wing section to pivot about the center section.

13. The agricultural machine of claim 7 , wherein both the first fastener and the second fastener engage the center section.

14. The agricultural machine of claim 7 , wherein both the first fastener and the second fastener engage the wing section.
