A screed machine is formed with a forwardly positioned screed assembly including a wedge portion and pivoted wing members. The frame is supported on two rollers spaced behind the screed assembly, which is mounted on a mast for vertical movement in conjunction with a laser receiver that provides a signal from a laser level indicating the final desired grade of the stone base. The machine can be turned at a corner by extension of a jack stand to elevate the machine for rotation about the axis defined by the centrally located jack stand so that the screed machine can be redirected into a different direction without disturbing the final grade of the stone base. The screed machine is manually moved along the stone base by an operator pulling on the handle pivotally connected to the frame. A sight line provides a monitor for the lateral orientation of the screed assembly.
