Ditcher

Abstract

Earth working apparatuses and more specifically a ditcher or slope cutting device adapted to be connected with a conventional three point hitch mounted at the rear of a conventional tractor. The earth working apparatus includes a rigid square or rectangular frame having pairs of pivot lugs spaced laterally on a front member thereof for pivotal connection to the lower links or arms of a three point hitch and a pair of centrally located upwardly disposed pivot lugs pivotally supporting an upright member having its upper end connected to the upper link or arm of the three point hitch. A hydraulic ram or mechanical structure interconnects the frame at a point spaced rearwardly from the front and an upper end portion of the upwardly extending member in order to adjust the angular relation between the frame and the upwardly extending member and angularly adjust the frame in relation to the three point hitch and in relation to the ground surface. The frame includes one or more ground engaging blades which are supported from the frame for adjustable rotatable or pivotal movement in relation to the frame and ground surface, by a hydraulic ram or mechanical structure, about an axis that is perpendicular to the frame thereby enabling adjustment of the plane of contact with the ground surface to be varied as to its angle of inclination due to the capability of varying the angular relation of the frame to the ground surface and the change in angular disposition of the blade or blades in relation to the frame about an axis perpendicular to the frame.
