ABSTRACT:
A handle assembly for attachment to a screed includes a clamp sized to receive either a wooden screed or a metal screed, a power handle extending upwardly from and fixed to the clamp for controlling the attitude of the screed and applying power to pull the screed over freshly poured concrete, and a pivoted handle pivoted relative to the power handle for applying downward pressure and lifting forces to the screed. A single handle assembly can be used with a short screed or multiple handle assemblies can be used with longer screeds. The arrangement permits controlled movement during multiple passes of the screed over freshly poured concrete by a workman in a standing position.
