Patent ID: 7806196

Claim:
An edger comprising: a main frame that can be advanced controllably relative to subjacent terrain; a cutting assembly on the main frame; a drive for rotating the cutting assembly around a first axis, the cutting assembly configured to produce a trench in underlying terrain as the cutting assembly is rotated by the drive in operation; and material repositioning structure on at least one of the main frame and cutting assembly for controllably repositioning material dislodged from underlying terrain by the cutting assembly to thereby avoid accumulation of dislodged material upon the edger as the edger is operated, wherein the material repositioning structure comprises a first material moving wall with a substantially flat surface that resides in a plane and faces in a leading circumferential direction as the cutting assembly is rotated, the first material moving wall intercepting and propelling material dislodged from underlying terrain by the cutting assembly as the edger is operated, wherein the plane is parallel to a plane containing the first axis, wherein the cutting assembly comprises a plurality of cutting teeth that are elongate each with a length extending along a line and the lines are transverse to the plane of the flat material moving wall surface.
