Abstract: A loader type construction vehicle includes a chassis having a longitudinal axis, a plurality of wheeled ground-engaging structures pivotally coupled to the chassis, and a steering control system. Each of the plurality of ground-engaging structures includes a wheel pivotable about a steering axis and drivable about a drive axis, wherein each of the wheeled ground-engaging structures is shaped and configured so that the wheel of each of the ground-engaging structures can be pivoted from a first angular position in which the drive axis is perpendicular to the longitudinal axis, to a second angular position that is at least 90° degrees from the first angular position. The steering control system is operatively connected to each of the ground engaging structures for pivoting the wheel of each of the ground-engaging structures about the steering axis.
