Abstract:
1. A portable vibratory wet concrete screed comprising: a blade for leveling wet concrete, the blade having a front edge and a rear edge; an exciter that is selectively driven to induce vibrations in the blade; at least one operator-manipulated handle that is connected to the blade and that extends upwardly and rearwardly from the blade; a laser receiver that is mounted on the screed at a height above an upper end of the handle; and an indicator that is operatively connected to the receiver and that provides a visual indication of the screed height relative to a desired grade, wherein the indicator is located remote from the receiver at a location which, when viewed from the perspective of a person standing in the vicinity of a screed operator, is at least substantially in a focus area so as to be capable of concurrently viewing the indicator and at least a portion of the rear edge of the blade; wherein the handle and the receiver are mounted on the blade via an adjustable mount assembly, the mount assembly including a base that is supported on the blade and a pedestal that is mounted on the base so as to rotate about a vertical axis wherein the handle and the receiver are foldable from an upright, operative position in which they extend well beyond at least one of a horizontal footprint and a vertical footprint occupied by the combination of the blade and the exciter, to a stowed position in which the handle and the receiver are positioned at least substantially entirely within said footprints.
