A drive mechanism for a concrete mixer comprising a planetary gear train interposed between a motor and the mixer housing for transmitting rotation to the mixer. The planetary gear arrangement comprises a sun gear in driving engagement with a plurality of planet gears for transmitting rotation thereto. Each planet gear is a double gear in simultaneous driving engagement with a stationary ring gear and a freely rotatable ring gear for transmitting rotation to the rotatable ring gear. The rotatable ring gear is secured to the mixer housing for rotation simultaneously therewith. In addition, a ball socket joint connection is provided for the mixer housing for absorbing substantially all the twisting motion for reducing strain on the vehicle or truck.
