A Concrete Vibrating Screed that uses dual, counter-rotating, 115 VAC, synchronized vibratory motors uniquely mounted to 6"W x 4"H x 6'L to 14'L aluminum beam to self-propel the Screed down the form as it quietly spreads, consolidates, levels, and surface finishes conventional, high-flow and self-compacting concrete. Uniform vibration for rapid and consistent concrete finishing without the injury and fatigue-causing action of pulling/pushing a screed the length of the bed.
