Apparatus for removing debris form the ground comprising a frame which supports a rotatable cylindrical brush having bristles projecting from its axis of rotation, a rotatable shaft member extending across the width of the brush, a scraper member extending across the width of the shaft member, and a guide member configured arcuately to follow the outside of the brush. In use, the frame is movable across the ground and the brush is in contact with the ground such that the bristles contact and catch any surface debris upon leaving the ground the bristles approach the shaft member which contra-rotates with respect to the brush such that surface debris is retained by the bristles as they move upwardly proximate the guide member which guides the debris upwardly for ejection, while the scraper member maintains the shaft member free of accumulated debris.
