A machine, such as a mobile asset, vehicle, or agricultural vehicle, includes a chassis, an adjustment system, and a wheel. The adjustment system replaces a conventional non-extendable leg connected between the chassis and the wheel of the machine. The adjustment system can extend and withdraw in length, such that the height of the machine can vary as needed.
