A powered rotary screed provides a powered strike tube that rotates to provide a finish to wet concrete during screeding and a drive tube that provides motive power to the screed to assist with the difficult task of removing excess concrete from a poured pad, or other horizontal concrete surface. The drive tube is split to provide two separate portions that can be independently controlled for easy control of the screed as the screed works concrete. The drive tube portions are elongate cylinders that are axially aligned and rotatable relative to one another. Separate motors drive respective drive tube portions and can be individually controlled to prevent skewing of the screed.
