Abstract
A wheeled concrete screeding device includes a wheeled unit having wheels for movably supporting a frame portion, and a screed head supported at the frame portion and following behind the wheeled unit when the wheeled unit is moved in a screeding direction. The screed head includes a grade establishing element and a vibratable member. The grade establishing element is generally vertically adjustable responsive to a signal from a laser receiver disposed at the screed head to establish a struck-off surface of the uncured concrete at a desired grade. The vibratable member is adjustably attached at the grade establishing element and the vibratable member at least partially floats behind the grade establishing element on the struck-off surface of the uncured concrete and is at least partially supported at the struck-off surface of the uncured concrete as the wheeled unit is moved in the screeding direction.
