Abstract
Apparatus for raking and cleaning topsoil of undesired materials has a frame supporting a scoop and a rake or comb of multiple tines on a shaft that is rotatable about the shaft's longitudinal axis. Rotation of the shaft can then be used to raise or lower the rake into a raking or combing engagement with the top soil. The scoop is also rotatably supported to allow it to be activated to accumulate undesirable materials. Hydraulic cylinders or equivalent apparatus are provided to activate alternately the rake or scoop as desired by the operator.
