Combination spreader/grader apparatus

An improved apparatus for spreading or grading a land surface, and to be pulled by a tractor or like vehicle, the apparatus comprising:

• a) a principal frame portion attachable to the tractor, including first and second parallel side walls engaging the surface to be spread or graded;
• b) a pair of parallel disposed blades positioned between the sidewalls, for cutting into the surface as the apparatus is pulled along the surface;
• and
• c) hydraulic means connected to one end of the blades for moving the one end of the blades to various positions along a length of one of the sidewalls, so that the blade may be positioned between a position perpendicular to a length of the sidewalls, to angulated positions in relation to the length of the sidewalls.

• b) a pair of parallel disposed blades positioned between the sidewalls, for cutting into the surface as the apparatus is pulled along the surface, first ends of the blades hingedly connected to the frame portion;
• d) hydraulic means connected to a second end of the blades for moving the second end of the blades to various positions along the length of one of the sidewalls, so that the blade may be positioned between a position perpendicular to the length of the sidewalls, to angulated positions in relation to the length of the sidewalls;
• and
• e) means for attaching a third blade to one portion of the frame, and a wheel member to a second portion of the frame, so that the frame can be pulled along an inclined surface and spreading or grading of the surface can be achieved as the third blade cuts into the inclined surface, and the wheel allows easy maneuvering of the frame along the inclined surface.

An improved apparatus for spreading or grading a land surface, and to be pulled by a tractor or like vehicle in a direction, the apparatus comprising:

• a) a principal frame portion attachable to the tractor, including first and second parallel side walls engaging the surface to be spread or graded;
• b) a pair of substantially parallel blades positioned between the sidewalls, said blade being selectively movable to an angled position relative to the direction of tow and each of the blades cutting into the surface as the apparatus is pulled along the surface;
• and
• c) a rear edge of the sidewalls being angulated from the vertical in substantially the same angular configuration as one of the cutting blades, so that when the cutting blade is positioned substantially at the rear edge of the sidewalls, the apparatus is able to be positioned adjacent a vertical structure such as a wall to achieve optimum grading or spreading.
