  • Patent number: 8083005
    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.
