Abstract: A load coupling apparatus for a wheeled vehicle includes load linkage members that pivotally suspend the vehicle and load weight below the axles of the vehicle, allowing limited relative displacement of the axles and the load in the direction of vehicle travel. The load is displaced by moving the axles in the desired direction of travel, whereafter the suspended load follows the axles in a swinging motion as the effects of gravity overcome the load inertia. The effort required to initiate movement of the load is significantly reduced due to the relative displacement of the axles and the load, and the mechanical advantage afforded by the load linkage members. Once in motion, the load continues to track the axles in the direction of travel, providing continued reduction in motive effort even when the load reaches a constant forward speed.
