ABSTRACT OF THE DISCLOSURE A spreader/grader is attachable to a three-point hitch associated with a tractor and includes a pair of curved cutting blades which are adjust- able so as to control cutting depth. The cutting blades are mounted between a pair of side runners and include curved cutting edges to facilitate spread- ing or grading operations. The positioning of the blades is variable both with respect to cutting depth and to angular orientation with the surface being graded through the use of hydraulic ram adjustment mechanisms provided at respective ends of the blades. Both blades may be attached to the spreader/ grader so as to present cutting edges directed in the same direction and their respective cutting depths may be varied from each other through the use of the hydraulic ram adjustment mechanisms, or alternatively, one or both of the blades may be positioned with their cutting edges reversely directed from the direction of forward movement of the pulling tractor so as to provide a grading or feathering operation.
