Claim:
An improved spreader/grader system, comprising: a. a frame having a pair of parallel first and second sidewalls; b. at least two spreader/grader blades having a lower edge for spreading or grading a surface upon which the spreader/grader rests, and the blades positioned parallel or non-parallel to one another between the sidewalls, with each end of the blades capable of being secured to each of the sidewalls in multiple positions; c. first and second continuous slots formed in each of the sidewalls to allow a first end of each of the blades to slide along the first slot; d. a hydraulic cylinder mounted to at least one of the parallel sidewalls and to the first end of at least one of the blades to move that end of the blade along the length of the first slot in the multiple positions; e. a second end of the blade engaged through the second slot and secured to the sidewall to allow the second end of the blade to rotate as the first end moves along the first slot; and f. means for attaching the frame to a vehicle, such as a tractor, for pulling the spreader/grader during the spreading/grading process.
