Abstract: A powered landscaping apparatus having a frame, at least one wheel on the frame through which the frame can be supported upon and advanced over a subjacent support surface, a blower assembly operatively positioned on the frame and having a fan assembly that is mounted to be turned guidingly around a vertically extending axis, and a drive on the frame for moving the fan assembly around the vertically extending axis. The blower assembly is configured to generate a pressurized supply of air that is propelled in a stream that is directed in a manner to continuously redistribute loose material that resides on the subjacent support surface as the fan assembly is moved around the vertically extending axis by the drive and the frame is advanced over the subjacent support surface.
