A food mixer (10) having a planetary gear system including a center shaft (32) having a center gear (42) mounted thereto, the center shaft (32) being drivingly coupled to a motor (24). The gear system includes an agitator shaft (44) having an agitator gear (46) mounted thereon and being oriented parallel to the center shaft (32) and located such that the agitator gear (46) meshes with the center gear (42). A ring gear (48) having a set of internal gear teeth (50) encircles the center gear (42) and the agitator gear (46) whereby the agitator gear (46) meshes with the ring gear (48). The gear system has a pair of agitator bearings (52, 53) located on the agitator shaft (44) and a top bearing (62) located on the center shaft (32) being vertically displaced from and radially overlapping the pair of agitator bearings (52, 53). A needle bearing (64) located on the center shaft (32) and the top bearing (62) allow the center shaft (32) and the agitator shaft (44) to be placed in close proximity.
