Abstract
A debris herding method and apparatus is described comprising a low power air blower and a tilted rotary rake. The air blower acts together with a tilted rotary rake to dislodge and impel the debris. A motor driven chassis transports the blower and the rotary rake across the lawn. The blower and rotary rake can be energetically powered, such as by a solar cell array mounted to the chassis. The present invention is directed to an energetically efficient device for moving debris on a surface, such as leaves on a lawn.
