This invention refers to a manual operated snow pusher, consisting of a shovel provided with several wheels and a handle. It earlier exists two types of wheel provided snow shovels. The first type is preventing the leading edge from engaging the surface frictionally. The disadvantage with this type of shovel is that it leaves a layer of snow left on the ground. The second type has the wheels behind the shovel to support the load. This type of shovels requires a fairly flat surface to work properly. This invention solves both those problems. The wheels are mounted with their rolling surface parallel to the shovels slipping surface and in rows that are parallel with the shovel's application direction. This embodiment makes it possible to move the shovel on both dry surfaces as on ice and deep snow. This without leaving a gap of snow left on the cleaned surface. |
