Appl. No.:

09/638323

Inventors:

Edwin A. Erickson - Milnor ND 58060-9750

International Classification:

E02D 1713

US Classification:

37366, 172149

Abstract:

A ditch digging and cleaning device includes a frame having a hitch and a pair of support arms with wheels, a pair of front blades, a pair of side blades, a pair of dispersing members rotatably attached to the frame, a drive system mechanically connected to the dispersing members, and a pair of deflector structures attached to the rear portion of the frame. The dispersing members are each comprised of a circular base, and a plurality of fan blades orthogonally attached to an upper surface of the circular base. The dispersing members are juxtaposed behind pans attached to the front blades. The dispersing members are also less than 45 degrees with respect to the ground surface. The blades preferably are V-shaped for penetrating hardened soil. Coulters may be added in front of the front blade for loosening the ground or a beater member. In operation, the front blades sever the dirt from the ground surface at a desired depth.
