Abstract:
An improved spreader/grader system, which includes a frame having a pair of parallel sidewalls; a plurality of spreader/grader blades positioned between the sidewalls and secured within a slot along the length of each of the sidewalls, each blade having a lower edge for spreading or grading a surface upon which the spreader/grader rests; a hydraulic cylinder attached to each end of each blade to allow each blade to be moveable along the length of the sidewall in a parallel or non-parallel relationship as desired by the operator; and a hydraulic cylinder system for attaching the frame to a vehicle, such as a tractor, for pulling the spreader/grader during the spreading/grading process. The blades of the spreader/grader may alternatively be secured in fixed positions between the sidewalls of the frame with a bolt/nut combination.
