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.

  1. 1. A combination rake and material-spreading implement, comprising: an elongate shaft; a rake head including a plurality of rigid tines, the rake head fixed at one end of the elongate shaft; a material-spreading implement including a substantially continuous plate, the material-spreading implement pivotally attached to the tool for rotational movement with respect to the rake head between a fully retracted position and a fully deployed position; and a lock for retaining the material-spreading implement at a position between the fully deployed position and the fully retracted position to adjust the effective length of the tines.
