A concrete float, float assembly, float adapter and interface, and float vibration apparatus and methods include a concrete float that have 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 hand tamper includes a handle and a tamping head. The handle has a cavity to hold a fluid. The tamping head includes apertures in the bottom. Fluid can flow from the handle through the apertures of the tamping head to coat a tamping surface on the bottom of the hand tamper. The fluid can, for example, prevent asphalt from sticking to the tamping head.

A remote controlled vibration imparting device for a concrete finishing tool includes a case that attaches to a float using standard bolt layouts. A motor housing is suspended in and attached to the case, and the motor housing partly surrounds a vibrator with a support, a rotor with a shaft and weighted body, a bi-directional motor, and a coupler between the shaft and the motor. Also in the case are a variable speed controller and a remote switch, both of which are electrically connected to the motor and a battery located on or in the case. The case further includes a removable lid that attaches to a concrete finishing tool.

A tool, such as an impact tool, comprising at least a first and a second grip members extending generally parallel to the shaft on each side of the shaft and configured such that each one of the first and the second grip members is grasped by a user with a respective hand of the user, thereby centering the user above a ground surface to be worked with the tool, with the user's legs spreading about shoulder width, the user's head centered between the user's feet, both the user's hands level on a line generally perpendicular to the shaft, and allowing the user to precisely control the working head.
