A steering system (25) for an articulated steered mobile work machine (10) h as a first sensor (66) for sensing the relative angular position of first and second machine sections (12, 14) and a second sensor (68) for sensing the relative angular position of second and a third machine sections (14, 16). A controller (70) determines for a sensed relative angle of the first and second machine sections (12, 14) the desired relative steering angle of the second and third sections (14, 16 ) and actuates a second control valve (42) to direct fluid flow to a second pair of fluid operated jacks (28) and pivot the third machine section (16) to a desired angular position relative to the second machine section (14). The second sensor (68) provides feedback as to the relative angular position of the second and third machine sections (14, 16).
