ABSTRACT:
A floating screed device has a first section for cutting through plastic concrete and a second section for floating on the plastic concrete. The two sections are pivotally coupled for rotational movement about a pivot point. Elevation of the second section is measured and used to rotate the first section as the floating screed device is moved through a volume of the plastic concrete that is unfinished. As a result, the second section pitches to follow the first section.
