Abstract
Self-propelled liquid dispensing equipment having ground engaging wheels and an active trailing link suspension system in which either suspension struts or air struts control suspension travel. A liquid pressure transducer is connected to a liquid reservoir to provide a control input that varies the assist given by the suspension struts or air strut in direct proportion to the quantity of liquid. A given suspension travel is maintained regardless of the quantity of liquid carried by the equipment.
