Lightweight apparatus for screeding and vibrating uncured concrete surfaces

A wheeled screeding device movable over a surface of uncured concrete and being operable and controllable by an operator not supported by said wheeled screeding device, said wheeled screeding device being operable to level and smooth the uncured concrete surface, said wheeled screeding device comprising:

• a wheeled support having a frame portion and a pair of wheels rotatably mounted to said frame portion, said wheels supporting a first end of said frame portion above the uncured concrete;
• a concrete surface working member mounted to a second end of said frame portion, said second end being opposite said first end, said concrete surface working member including a vibratable member, said concrete surface working member being at least partially supportable on the uncured concrete surface;
• and
• a grade setting device adjustably mounted to said concrete surface working member, said grade setting device being adjustable relative to said concrete surface working member to engage the uncured concrete surface and establish a desired grade elevation for the uncured concrete surface, said concrete surface working member rests upon the uncured concrete surface at the established grade elevation and provides support for said second end of said frame portion while said wheeled support is moved over or through said uncured concrete and while said grade setting device engages the uncured concrete surface and establishes said desired grade elevation.
