An articulated utility vehicle having forward and rearward frame portions, each supported by a roller. A pair of fluid-powered rotary actuators are positioned between the front and rear frame portions of the vehicle. One actuator accomplishes side shifting of the rear frame portion relative to the front frame portion. The side shifting actuator has its drive shaft secured to the front frame portion and is oriented with its longtitudinal axis extending horizontally. The other actuator provides for steering of the vehicle. The steering actuator has its body rigidly attached to the rear frame portion and has its axis oriented vertically. The steering actuator is positioned immediately below the side shifting actuator, and has its drive shaft extending upwardly to pivotally couple to a clevis rigidly attached to the body of the side shifting actuator. The actuators can be separately and simultaneously operated to achieve separate and simultaneous steering and side shifting of the vehicle.
