ABSTRACT:
A powered landscape rake for fine grading of and for stone and debris removal from a landscape surface is shown according to the teachings of the present invention. The rake of the present invention includes a drum rotatably mounted in a drum frame. The drum frame is mounted to a turntable assembly for allowing the drum frame to pivot about an axis generally perpendicular to the drum frame and which is located generally midway of the drum frame. A frame member is attached to the turntable and extends to a point under the tractor frame in front of the front wheels. The free end of the frame member is mounted for pivoting and swiveling to a frame attachment member. First and second cylinders are further attached to the turntable for positioning the drum frame at any desired angle in a vertical plane to the landscape and allow the drum frame to sway in a horizontal plane about the front frame attachment point. The drum can be rotated in either direction by a hydraulic motor for providing a kicking type action to the soil of the landscape surface for providing a smooth, fine, finished grade and for seeding and covering seed on the landscape surface.
