Claim:
An excavating apparatus for scraping loose matter from a surface, comprising: a main blade having a pushing surface adapted to contact said loose matter, a vehicle coupler surface generally parallel to and spaced from said pushing surface terminating at two distally opposed ends at two pin hinges, and two distally opposed taper surfaces, each sloping away from said pushing surface towards a respective one of said pin hinges and attached along a complete length of the pin hinges; a first wing coupled to a first one of said two pin hinges and pivotal thereabout, wherein a portion of said first one of said pin hinges is absent and defines a void to facilitate extension of a powered extensible and retractable member rotating said first wing about the first pin hinge; and a first position defined by the passage of the powered extensible and retractable member into the void without interference with the first pin hinge to move said first wing into a substantially perpendicular position forward of the main blade and the power member.
