Abstract
A portable vibratory wet concrete screed includes a blade, an exciter that is selectively driven to induce vibrations in the blade, at least one operator-manipulated handle connected to the blade and extending upwardly and rearwardly, a laser receiver mounted on the screed at a height above an upper end of the handle, and an indicator that is operatively connected to the receiver. The indicator provides a visual indication of the screed height relative to a desired grade. It is located remote from the receiver at a location which, when viewed from the perspective of a person in the vicinity of a screed operator, is at least substantially in a focal area containing the rear edge of the blade. The handle is mounted on the blade so as to be foldable from an upright, operative position in which it extends vertically and horizontally well beyond horizontal and vertical footprints occupied by a combination of the blade and the exciter to a stowed position in which it is positioned at least substantially entirely within the horizontal and vertical footprints.
