Abstract
A spreader/grader attachable to a three point hitch of a tractor and including a pair of longitudinally extending, parallel, transversely spaced side pans or frame members oriented in fixed relation to each other and operatively connected to a three point hitch. Extending between the side pans or frame members is a plurality of transverse blades for engaging a soil surface in order to perform various earth working functions. The blades include a support structure and attachment arrangement at each end thereof for connection with the side pans or frame members to enable the blades to be oriented in a fixed or varied relation to the frame members or adjustable in relation to the frame members to orient either end of a blade forwardly or rearwardly in relation to the other end and either end of the blade upwardly or downwardly in relation to the other end and to vary the angle of a blade about a longitudinal axis with respect to a horizontal plane to vary the angle of attack of the blade in relation to the soil surface in order to provide effective grading, spreading and other earth working functions.
