ABSTRACT:
An earth engaging instrumentality is equipped with wedge-like surfaces for displacement of earthen material. Rollers are rearwardly offset from the leading edge of the instrumentality and have chordal segments projecting outwardly beyond the diverging surfaces of the instrumentality to displace earthen material and hence facilitate penetration of same. An open, roller receiving area of the instrumentality is shown as being of a non-uniform width to receive upper and lower rollers of different widths which rollers may be of different peripheral configuration.
