Vehicles or implements feature walking beam assemblies each having a front wheel and rear wheel carried adjacent opposite ends of the walking beam on opposite sides of a pivot point thereof. The conventional single beam is replaced by a split beam arrangement in which front and rear beams are pivotal relative to one another by an actuator, whereby changing the angle between the front and rear beams lifts or lowers the main pivot of the walking beam in order to adjust the height of the respective side of the vehicle frame. The split walking beam can be used to adjust the tilt angle of a scraper blade or other ground working arrangement in a land leveler or other earth working machine. |
