ABSTRACT:
A rotating cylinder cement screeding system having a drive assembly and handle at one end for powering and controlling the screeding system. The rotating cylinder is made of tubular screed rollers of varying lengths allowing a user to customize the length of the system to match a specific cement pour. Further, each tubular screed roller is supplied with a male and female end for interlocking with each other and for receiving a variety of add on attachments. One of these attachments is a center anchor member that allows the screeding system to be used to finish circular concrete pours. In this regard, the center anchor member may be used to anchor a non-powered end of the rotating cylinder when finishing circular concrete pours.
