This invention relates to a vibrating screed for compacting and smoothing flowable cementitious materials. More specifically, this invention relates to a self- contained hydraulic powered concrete screed. This hydraulic screed consists of a relatively lightweight screed unit having a hydraulic powered vibrator and a portable hydraulic power pack that is mounted on a back pack wearable by the operator. The handle of the screed unit is isolated from the hydraulic vibrator and screed blade by three rubber isolation mounts. The working height of the handle can be adjusted by a turnbuckle assembly at one of the rubber mounts, causing the handle to pivot about the other two the rubber mounts. The hydraulic power pack comprises an internal combustion engine driving a hydraulic pump that provides pressurized hydraulic fluid to the vibrator unit via flexible hoses.
