  • Patent number: 6347670
    Abstract: An apparatus for modifying the earth's surface by removing soil from the surface, moving the soil to a new location and filling low areas. It comprises a frame carried by at least two wheels, a tongue mounted to the frame for attachment to a tractor, a cutting blade mounted on the frame, and a bucket pivotally mounted to the frame adjacent the blade to receive the soil cut by the blade. The wheels are pivotally mounted to the frame for movement of the wheels about the back wall and floor of the bucket between a first position and a second position. When the wheels are in the second position, a portion of each of the wheels underlies a portion of the floor of the bucket bringing the wheels closer to the center of gravity of the apparatus and its load.

  • Patent number: 4398363
    Abstract: Earth moving, ground leveling and land planing apparatus having a substantially rectangular frame which is pivotally attached at the back end thereof to a support member containing ground engaging wheels. A cutting blade is disposed laterally between the bottom sides of the frame and a bucket having an open front end is pivotally mounted at its lower forward edge to the frame adjacent the blade for swinging between a generally horizontal earth loading position and an upwardly tilting unloading position. An apron comprising a swingable gate is provided to form an operable front wall for the bucket. Means are provided for swinging the apron about a pivot axis which is transverse of the frame, at a vertical distance above the bottom of the frame equal to at least about one-half the vertical depth of the bucket and displaced forward of the blade.

  • Patent number: 4388769
    Abstract: Earth moving, ground leveling and land planing apparatus having a substantially rectangular frame which is pivotally attached at the back end thereof to a support member containing ground engaging wheels. A cutting blade is disposed laterally between the bottom sides of the frame, and a bucket having an open front end is provided with the forward edge of the floor of the bucket being mounted to the frame adjacent to the trailing edge of said blade. A blade support member extends from the back end to the forward end of the frame substantially along the longitudinal axis of the frame. A downwardly extending projection from the blade support member is integrally attached as by welding to the cutting blade at a position substantially intermediate the cutting width of the blade.

  • Patent number: 4383380
    Abstract: Earth moving, ground leveling and land planing apparatus having a substantially rectangular frame which is pivotally attached at the back end thereof to a support member containing ground engaging wheels. A cutting blade is disposed laterally between the bottom sides of the frame and a bucket having an open front end is pivotally mounted at its lower forward edge to the frame adjacent the blade for swinging between a generally horizontal earth loading position and an upwardly tilting unloading position. A pair of hydraulic rams are provided, one ram for each side of the frame for lifting and pivoting the bucket. Mutually respective ends of the hydraulic rams are attached to the side members of the frame at a point along the longitudinal lengths of the side members which is between about the midpoint and back edge of the floor of the bucket when the bucket is in its lowered load carrying position. The other ends of the rams are connected to the bucket near the respective back upper edge corners thereof.
