ABSTRACT:
A new and improved combined snow pusher, ice chopper, and broom apparatus for clearing a surface includes a handle which is supported by a support and which projects upward from the top of the support at a first acute angle with respect to the support. Bristles are supported by the support, and the bristles project downward from the bottom of the support by a first distance. A panel element is supported by the support at the front of the support. The panel element is connected directly to the support, and the bottom end of the panel element projects downward past the bottom of the support by a second distance. The second distance is less than the first distance, whereby the portion of the panel element which extends below the support element protects the interface between the bristles and the support, whereby the panel element does not contact the surface to be cleared. The bottom end of the panel element includes a sharp lower edge. In a first mode of operation, the bristles are placed on the surface to be cleared, the panel element is used to push material out of a path on the surface, and the bristles are used to sweep material out of the path on the surface. In a second mode of operation, the apparatus is rotated 180 degrees, and the sharp edge of the panel element is placed on the surface to be cleared. In this mode, the apparatus can be used for chopping ice.
