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 hand tool includes a tool handle and a tool head having a body portion, with the handle secured to a back support plate portion which connects normal relative to the back plate portion, a first plate portion extending from a first side of the back plate portion having a toothed edge and a second plate portion extending from a second side of the back plate portion having a level edge, wherein each of the plate portions extend at an angle of from between 5 to 45 degrees relative to the back support plate portion.

A pair of articulating screed framework extensions, independently adjustable at least two locations along each extension, independently adjusting each extension to a comfortable working height and other subjective needs of each user, each extension providing an upper plate on a first section, a hand grip on a second section and distal end on a third section to which a screed workpiece is independently attached to locate a width between each extension, with a locking pivot joint between each first and second section and each second and third section.

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.
