Abstract
An apparatus determines the payload carried in a work vehicle by periodically measuring the pressure of a fluid contained within front and rear suspension struts. The struts are connected in supporting relation between a load carrying portion and a ground engaging portion of the vehicle such that a pressure differential between a loaded and unloaded vehicle can be shown to be indicative of the magnitude of the payload. Moreover, the pressures are a function of the geometry of a suspension means which interconnects the load carrying portion and the ground engaging portion.
