A hand shovel assembly facilitates emptying of the shovel with minimal lifting. The assembly includes a shaft having an upper end and a lower end. A pan is coupled to the lower end of the shaft. The pan has a bottom wall, a back wall which extends upwardly from the bottom wall, and a pair of side walls coupled to and extending forwardly from opposite ends of the back wall defining an interior space of the pan. An upper wall is coupled to the pan over the bottom wall. A motivator is coupled to the pan between the bottom wall and the upper wall. The motivator selectively urges the upper wall away from the bottom wall wherein the upper wall is configured to urge material in the interior space of the pan out of the interior space.
