Claim:
A portable concrete striking device capable of being manually pulled without a motorized device, and capable of being carried by a worker comprising: an elongated portable screed defining opposite first and second ends, wherein said elongated portable screed is cross-sectionally generally L-shaped and comprises a blade for flatly engaging concrete being struck and a concrete push wall integrally linked to said blade and transversely upstanding therefrom; a handle member, mounted to said elongated portable screed, and configured for allowing the worker to manually pull the screed in an upstream direction; an elongated auger, rotatably mounted to said screed and extending at least from said first to said second ends of said elongated portable screed, and located upstream of said screed when said portable concrete striking device is in use and being manually pulled; and a motor, mounted to one of said screed and said handle member, and operatively linked to said auger, and configured for rotating said auger; wherein said portable concrete levelling device is adapted to rest directly on concrete being levelled with said screed without support from a wheeled support structure, and wherein said auger is configured for directing excess concrete upstream of said screed towards an excess concrete discharge location which is located at a predetermined position along said elongated screed proximate one of said first and second opposite ends, wherein said portable screed comprises an excess concrete evacuation mechanism at said excess concrete discharge location for evacuating excess concrete away from said screed of said auger and wherein said excess concrete evacuation mechanism comprises an excess concrete discharge opening in said screed at said excess concrete discharge location, with said auger extending partly upstream of said excess concrete discharge opening.
