Patent ID: 8544558

Claim:
A tongue-pulled spreader and grader system, comprising: a. a frame, having a pair of spaced apart sidewalls; b. at least one blade positioned between the sidewalls for making contact to a surface to be graded; c. an axle spanning across and positioned above the sidewalls; d. a brace mounted on each end of the axle at a first end and secured to a rotatable wheel at a second end of each brace; e. a mounting member extending between the midpoint of the axle at a first end and a hydraulic cylinder at a second end; f. said hydraulic cylinder mounted to the mounting member at a first end of the hydraulic cylinder and mounted to the frame at a second end, for receiving hydraulic fluid to expand and retract the cylinder for moving the mounting member back for imparting rotation to the axle and movement to the braces attached to the wheels to raise and lower the wheels from a first position resting on the surface to a second position off the surface and above the level of the blade to allow the blade to cut into the surface as the frame is pulled along the surface; g. the hydraulic cylinder further imparting rotation of the axle in the opposite direction to move the wheels from the second position above the blade to return to the first position resting on the surface; and h. a mountable container for containing said hydraulic fluid.
