Abstract
A self-propelled construction machine includes machine frame that is laterally extendible to adjust a width of the machine frame. A frame lock can selectively lock and unlock the machine frame to permit the width adjustment. A controller includes a frame extension mode configured to steer at least one ground engaging unit to provide a lateral force to adjust the width of the machine frame as the machine is driven across the ground surface by the ground engaging units.
