That implement is a Valley Engineering "crud-buster" for lack of a better name. It was a pre-curser to the modern renovators used to break up into chunks hard packed snow and icy areas. It leaves quite a mess, but a powdermaker or tiller along with a lot of patience would gain an acceptable finished product.
