A stand mixer , comprising: a drive motor having an output shaft operably associated therewith; a locking planetary output ; a mixing head enclosing the drive motor and with which the locking planetary output is mounted; a stand supporting the mixing head above a work surface (S); and a mixing bowl removably coupled with the stand and defining an inside surface ; wherein the locking planetary output includes: a center shaft operably connected with the output shaft of the drive motor for driven rotation about a fixed axis ; and a n agitator shaft mounted to the center shaft such that the agitator shaft is able to move 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 to maintain a rotational position, in particular 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 , wherein the stand mixer further comprises a mixing element removably coupled with the agitator shaft , the mixing element including at least one wiping edge , in particular a pair of wiping edges arranged at opposite sides of the mixing element , the at least one wiping edge being in periodic contact with the inside surface of the mixing bowl when the gear unit is in the first position and being in constant contact with the inside surface when the gear unit is in the second position. a drive motor having an output shaft operably associated therewith; a locking planetary output ; a mixing head enclosing the drive motor and with which the locking planetary output is mounted; a stand supporting the mixing head above a work surface (S); and a mixing bowl removably coupled with the stand and defining an inside surface ; a center shaft operably connected with the output shaft of the drive motor for driven rotation about a fixed axis ; and a n agitator shaft mounted to the center shaft such that the agitator shaft is able to move 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 to maintain a rotational position, in particular 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 , <EOS>
