A work vehicle is provided with an articulated frame having a first frame segment and a second frame segment that are pivotally coupled to one another by a vertical pivot. An actuator is coupled to the frame segments for articulating the segments relative to one another to steer the vehicle. Each frame segment is provided with ground engaging wheels which support the respective frame segments. A work implement in the form of a backhoe is mounted to the second frame segment. A stabilizer having two stabilizer arms is mounted to the first frame segment. The stabilizer arms have a work position and a transport position. In its work position the stabilizer arms are lowered and the ground engaging wheels of the second frame segment are lifted off the ground. The actuator for steering the vehicle can then be used to pivot the backhoe about a vertical axis defined by the vertical pivot.
