A hauling system for a self-propelled vehicle and a trailer that is not self-propelled in which the self-propelled vehicle and the trailer are releasably connected by a system that is operable by a single operator who can align and connect the self-propelled vehicle and the trailer from the cab of the self-propelled vehicle. Lateral alignment is achieved by steering the self-propelled vehicle and is facilitated by masts located on the self-propelled vehicle and the trailer that are visible from the cab. Vertical alignment and the physical connection are completed through use of a jack or other lifting mechanism that is positioned on the trailer and is operated by a wireless control signal sent from the cab.
