Claim 6:
7. A method for controlling turf grading equipment comprising:
providing a turf grading device and moving said turf grading device longitudinally over an area wherein said turf grading device comprises a left side and a right side with each side being able to independently move vertically and said left side and said right side move in concert to provide a motion of pitch and yaw;
moving said left side and said right side independently by a control system comprising:
selecting between a manual override mode and a module selection mode wherein said module selection mode selected from a grade adjust laser mode, a grade adjust autograde mode, a grade adjust autodepth mode and a grade adjust slope mode by a controller interface;
transmitting a laser beam over said area by a laser transmitter, when said grade adjust laser mode is selected, wherein said laser transmitter is in a fixed location relative to said area;
detecting said laser beam by at least one laser sensor on said turf grading device wherein said laser sensor moves in concert with said left side or said right side of said turf grading device;
determining a location of said laser sensor relative to said laser beam by a grade adjust laser mode controller and actuating a transport cylinder to move said right side or said left side vertically by a laser control logic module;

determining a height above said area by at least one radar proximity sensor, when in said grade adjust autograde mode, wherein said radar proximity sensor moves in concert with said left side or said right side of said turf grading device;
receiving said height by a autograde controller and relaying a height signal to a proximity control logic module wherein said proximity control logic module actuates said transport cylinder to move said right side or said left side vertically;

determining the extent of extension of said transport cylinder by at least one transport cylinder sensor when in said grade adjust autodepth mode wherein said transport cylinder sensor relays said extension to a transport cylinder controller wherein said transport cylinder controller relays said extension to a cylinder control logic module which actuates said transport cylinder to move said right side or said left side vertically; and
determining a slope by a slope sensor, when in said grade adjust slope mode, wherein said slope sensor determines an angle of said turf grading device relative to a lateral direction and relays said angle to a slope controller wherein said slope controller relays said slope to a slope control logic module wherein said slop control logic module actuates said transport cylinder to move said right side or said left side vertically to adjust said yaw of said turf grading device.
