Abstract
A combination rake and material-spreading tool includes an elongate handle, a raking implement attached to an end of the handle, and a material-spreading implement. The material-spreading implement includes a substantially continuous plate that is moveable between a retracted position in which the material-spreading implement exposes the rake tines for normal raking operations and a fully deployed position in which the material-spreading implement is positioned with a lower edge of the substantially continuous plate positioned proximate distal free ends of the tines. An actuator is mounted on the handle, and a mechanical linkage operably connects the actuator with the material-spreading implement, whereby positioning of the material-spreading implement is achieved by manipulation of the actuator.
