Abstract: A new concrete mixing device for mixing concrete as a user moves the device along a ground surface. The inventive device includes a rolling drum with one of the ends of the rolling drum having an opening into the interior of the rolling drum. The device also includes a handle member having opposite first and second ends and a pair of arms. The arms are spaced apart from each other at the first end of the handle member. Each of the arms has a mounting pin extending therefrom that face one another. The rolling drum is interposed between the arms with each of the ends of the rolling drum rotationally mounted to an associated mounting pin to permit free rotation of the rolling drum. A pair of hand grips are extended from the second end of the handle member.
