Abstract
A self-propelled construction machine includes a plurality of swing legs, each swing leg being supported from a ground surface by an associated crawler track steerably connected to an outer end of its associated swing leg. Pivotal movement of a swing leg may be accomplished by steering the associated crawler track through a non-zero steering angle until the lateral movement of the crawler track achieves the desired pivoting movement of the associated swing leg.
