Abstract

A land leveling device for leveling uneven surfaces. The land leveling device generally includes a frame adapted to be removably attached to a tractor. The frame will generally include a rear support, a first side support extending in a forward direction from a first end of the rear support and a second side support extending parallel to the first side support from a second end of the rear support. A central rod will preferably extend forward from a central point on the rear support parallel to and between the first side support and second side support. A pair of leveling members are each fixedly attached to the side supports at their respective ends and pivotally attached to the central rod. As the land leveling device passes over terrain, the leveling members automatically pivot about the central rod to adjust for uneven surfaces.

Claims

1. A land leveling device, comprising:

a frame adapted to be removably attachable to a tractor, wherein said frame includes a rear support, a first side support and a second side support, wherein said first side support extends from a first end of said rear support, wherein said second side support extends from a second end of said rear support, wherein said first side support and said second side support extend perpendicularly with respect to said rear support;

a central rod extending from said rear support, wherein said central rod extends perpendicular to said rear support, wherein said central rod is positioned between said first side support and said second side support;

a first leveling member extending from said first side support to said second side support, wherein said first leveling member is pivotally connected to said central rod such that said first leveling member pivots about said central rod; and

a second leveling member extending from said first side support to said second side support, wherein said second leveling member is pivotally connected to said central rod such that said second leveling member pivots about said central rod, wherein a first end of said first side support is rotatable connected to said first end of said rear support, wherein a first end of said second side support is rotatably connected to said second end of said rear support.

2. The land leveling device of claim 1, further comprising a first ball joint connecting said first end of said first side support to said first end of said rear support and a second ball joint connecting said first end of said second side support to said second end of said rear support.

3. The land leveling device of claim 1, wherein a first end of said first leveling member is rotatably connected to a second end of said first side support, wherein a second end of said first leveling member is rotatably connected to a second end of said second side support.

4. The land leveling device of claim 3, further comprising a first ball joint connecting said first end of said first leveling member to said second end of said first side support and a second ball joint connecting said second end of said first leveling member to said second end of said second side support.

5. The land leveling device of claim 3, wherein a first end of said second leveling member is rotatably connected to said first side support, wherein a second end of said second leveling member is rotatably connected to said second side support.

6. The land leveling device of claim 5, further comprising a first ball joint connecting said second leveling member to said first side support and a second ball joint connecting said second leveling member to said second side support.

7. The land leveling device of claim 1, further comprising a first pivot member rotatably extending around said central rod, wherein said first pivot member is fixedly attached to said first leveling member.

8. The land leveling device of claim 7, further comprising a second pivot member rotatably extending around said central rod, wherein said second pivot member is fixedly attached to said second leveling member.

9. A land leveling device, comprising:

a frame adapted to be removably attached to a tractor, wherein said frame includes a rear support, a first side support and a second side support, wherein said first side support extends from a first end of said rear support, wherein said second side support extends from a second end of said rear support, wherein said first side support and said second support extend perpendicularly with respect to said rear support, wherein a first end of said first side support is rotatably connected to said first end of said rear support, wherein a first end of said second side support is rotatably connected to said second end of said rear support;

a first ball joint connecting said first end of said first side support to said first end of said rear support;

a second ball joint connecting said first end of said second side support to said second end of said rear support;

a central rod extending from said rear support, wherein said central rod extends perpendicular to said rear support, wherein said central rod is positioned between said first side support and said second side support;

a mount assembly connected to said rear support for removably attaching to a lift member of said tractor;

a first cross bar linking said mount assembly with said central rod;

a second cross bar linking said mount assembly with said central rod;

a first leveling member extending from said first side support to said second side support, wherein said first leveling member is pivotally connected to said central rod such that said first leveling member pivots about said central rod, wherein a first end of said first leveling member is rotatably connected to a second end of said first side support, wherein a second end of said first leveling member is rotatably connected to a second end of said second side support;

a third ball joint connecting said first end of said first leveling member to said second end of said first side support;

a fourth ball joint connecting said second end of said first leveling member to said second end of said second side support;

a second leveling member extending from said first side support to said second side support, wherein said second leveling member is pivotally connected to said central rod such that said first second member pivots about said central rod, wherein a first end of said second leveling member is rotatably connected to said first side support, wherein a second end of said second leveling member is rotatably connected to said second side support;

a fifth ball joint connecting said first end of said second leveling member to said first side support;

a sixth ball joint connecting said second end of said second leveling member to said second side support;

a first pivot member rotatably extending around said central rod, wherein said first pivot member is fixedly attached to said first leveling member; and

a second pivot member rotatably extending around said central rod, wherein said second pivot member is fixedly attached to said second leveling member.
