Abstract: An adjustable grader-spreader bar with a three-point hitch has a blade frame assembly comprised of a plurality of blade frames, each blade frame having a blade edge fastened at the bottom. The blade frames are slideably connected so that the blade frames have an adjustable overlap. Actuating devices, such as hydraulic rams, are used to extend or retract the blade frames, so that the width of the of the adjustable grader-spreader bar may either be increased or decreased as required for the particular application. Ground engaging skids are attached to each side of the blade frame assembly. The vertical position of each ground engaging skid may be adjusted to raise or lower each side of the adjustable grader-spreader bar. Actuating devices, such as electrical motors, are used to change the vertical position of the ground engaging skids.
