Abstract
A lightweight screeding apparatus for screeding and smoothing an uncured concrete surface includes a concrete surface working member, such as vibrating beam or member, and a grade setting device adjustably mounted to said vibrating beam. The screeding apparatus may include a wheeled support which at least partially supports the vibrating beam and/or the grade setting device. The wheels of the wheeled support may be powered or driven to assist an operator in moving the screeding apparatus over and through the uncured concrete. The grade setting device is vertically adjustable to set or indicate the desired grade of the concrete surface as the screeding apparatus is moved over and through the uncured concrete. The grade setting device may be adjusted by means of a laser plane responsive control system.
