1. A stand mixer, comprising:
a drive motor having an output shaft operably associated therewith; and
a locking planetary output, including:
a center shaft operably connected with the output shaft of the drive motor for driven rotation about a fixed axis;
an agitator shaft mounted to the center shaft such that the agitator shaft moves around the fixed axis of the center shaft in a planetary arrangement;
a planetary gear centrally arranged about the fixed axis of the center shaft; and
a gear unit rotatably fixed on the agitator shaft and slidably mounted therewith to be moveable between a first position, in which the gear unit is engaged with the planetary gear to cause rotation of the agitator shaft about a moving axis thereof during movement of the agitator shaft around the fixed axis by the center shaft, and a second position in which the gear unit is disengaged from the planetary gear and is engaged with a locking member to maintain a predetermined rotational position of the agitator shaft about the moving axis thereof during movement of the agitator shaft around the fixed axis by the center shaft.
