A system and method for limiting articulation between a front frame and a rear frame of an articulated machine are disclosed. The system and method receive steering signals and determine impending contact between the front frame and the rear frame based on the received steering signals. Additionally, an amount by which to reduce torque at a hitch coupled between the front and rear frames so as to limit an articulation characteristic of the front frame relative to the rear frame to a predetermined value is determined, responsive to determination of impending contact. Prior to contact, rimpull of the articulated machine is reduced based on the determined amount of torque.
