A concrete float, float assembly, float adapter and interface, and float vibration apparatus and methods are described. A concrete float has improved surfaces, and structures for controlling flow of wet concrete. An interface such as may be included in a quick attach/release configuration may be integrated on a float, and/or may be added onto a float for quick attach/release of a pivot assembly. Adapters may ease attachment or release of an assembly, and may be an interengaging element, such as a sliding dovetail as an interengaging element, or an adapter may be used to place an assembly in tension to secure the assembly. A vibration assembly may be included and configured to have a low center of mass, can have a user display, an accelerometer, and/or other components. A pivot assembly may be included for easier use by an operator, and may include a user display, quick release mechanisms.

A concrete finishing tool that more effectively fills and smooths voids on the surface of a slab of wet concrete includes a float; one or more wet concrete holding trays positioned on top of the float; electrically operated cylinders or other actuators for raising the trays to dump the wet concrete onto a concrete slab; and a mechanical vibrator for vibrating the trays to urge concrete from the trays onto the slab.

A concrete scraper has a rectangular shaped sheet metal body attached to an elongated handle. The rectangular shaped body has a top edge configured to scrape and finish concrete. Concrete grabbing steel wires extend downwardly from the front of the body opposite the top edge of the body. Users have the option of rotating the scraper to scrape concrete with or without the steel wires.
