Abstract
An edger has a main frame that can be advanced controllably relative to a subjacent terrain, a cutting assembly on the main frame, a drive for rotating the cutting assembly around a first axis, and material repositioning structure on at least one of the main frame and cutting assembly. The cutting assembly is configured to produce a trench in underlying terrain as the cutting assembly is rotated by the drive in operation. The material repositioning structure controllably repositions material dislodged from underlying terrain by the cutting assembly to thereby avoid accumulation of dislodged material upon the edger as the edger is operated.
