Abstract

A power head for a powered concrete roller screed includes a handle and a driver housing at a distal end of the handle. A cordless, battery-operated driver is received in the driver housing. A head actuator includes a translatable link extending along the handle and an eccentric cam. The eccentric cam is operatively connected to the translatable link within the drive housing such that translation of the translation link imparts rotation of the eccentric cam about a rotational axis of the eccentric cam to an actuated position. The eccentric cam is adjacent a trigger of a cordless, battery-operated driver and is configured to depress the trigger when the eccentric cam is rotated about its rotational axis to the actuated position.
