Orbital vibrating hand trowel

Abstract

The orbital vibrating hand trowel has a body with first and second opposite ends and a handle between the ends for grasping. The body houses a motor and power source. An eccentric mass is connected to the motor. An adapter body is connected to a float body. The adapter body has an aperture for housing the eccentric mass such that rotation of the eccentric mass within the aperture of the adaptor body moves and vibrates the adaptor body and attached float body in an orbital path along a horizontal plane with respect to the float body for finishing a surface.
