A manually portable rotary debris remover, particularly adapted for clearing tree planting sites, has a remotely mounted, power driven, rotating hub on an extended support, such as a chain saw blade. The rotationally driven hub has a plurality of pairs of coiled tine members, each pair radiating out from a respective tine shaft mounted in the hub equidistantly from the hub axis. The tine shafts are each inclined from 3 to 10 degrees from perpendicular to the plane of rotation of the hub, so that, in rotating, the tines of each pair do not simultaneously strike objects in the path of rotation of the tines when clearing debris.
