The livestock confinement pasture machine (10) includes a confinement unit (12) for confining livestock within a defined area. A drive assembly (36) is mounted upon the confinement unit (12) for moving the confinement unit (12) at a preset speed. The drive assembly (36) and the direction of movement of the confinement unit (12) are controlled by a steering unit (100) which operates to sense and follow a preformed direction control path (134) for the livestock confinement pasture machine (10). If the confinement unit (12) engages a large obstacle or the steering unit (100) loses the direction control path (134), disengagement units (98, 132) are provided to terminate operation of the drive assembly (36).
