초록 ▼

A snowplow carriage assembly for removal of snow manually by plowing the snow in an area to be cleared of snow. The carriage is a manually propelled wheeled structure made of a plurality of members pivotally connected for collapsing and folding for storage and unfolding for use in supporting and transporting a snowplow in the form of a replaceable conventional snow shovel having a handle straight length portion. The carriage is configured so that the snow shovel handle is removably mounted thereon inclined from the horizontal defining an acute angle relative to a surface on which snow is being plowed. The snow shovel inclination is variable for establishing different acute angles of the shovel relative to the surface for plowing the snow thereon and removal therefrom.
