The present invention is directed to a planetary steering system for a skid steered vehicle. A prime mover directs rotational motion through right and left drive shafts having planetary carriers with planet gears. The planet gears of the right and left planetary carriers rotate around a right and left sun gears that are coupled to right and left hydraulic steering motors. The planet gears rotate in right and left ring gears that are coupled to the right and left drive wheels of the vehicle. By rotating the motors the speed of the drive wheels can be independently controlled.
