Abstract
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.

4. Apparatus for removing debris from the ground, the apparatus comprising:
-
a) a frame; b) ground engaging wheels carried on said frame; c) a hopper carried on said frame to receive debris; d) a subframe pivotally mounted on said frame on a first pivot; e) a ground engaging brush having a generally horizontal axis carried on said subframe for rotational movement; f) means for rotating said ground engaging brush about said generally horizontal axis; g) an arm mounted on a second pivot on said subframe for pivotal movement about said generally horizontal axis; h) a roller having an axis generally parallel to said axis of said brush said roller terminating in ground engaging wheels and having a central portion 10 to 50 mm from the ground, said roller being carried on said arm; i) an arcuate guide mounted on said arm and disposed about said brush; j) means for displacing said arm about said second pivot; and k) means for displacing said ground engaging brush relative to said subframe.
