The present invention relates to a boom suspension and lift assembly which is mounted to extend laterally from a vehicle for agricultural spraying purposes. The boom assembly comprises a main frame mounted on the vehicle and at least one boom pivotally mounted on the main frame. A suspension system between each boom and the main frame independently absorbs boom motion resulting from vehicle travel over uneven terrain. A boom lifting system is provided to selectively lift each boom relative to the main frame by pivoting the boom about a longitudinal axis adjacent the main frame. For transport or storage, each boom is foldable against a side of the vehicle.

A boom assembly mountable on a vehicle which comprises: a main frame; means to mount the main frame on a vehicle; a separate boom extending laterally from each side of the main frame, each boom including a generally upright base post and a generally upright link and having laterally extending upper and lower members pivotally connected on separate vertically spaced longitudinal axes to the generally upright link at their outer ends and pivotally connected on separate vertically spaced longitudinal axes with respect to the generally upright base at their inner ends, and the base post being pivotally mounted with respect to the main frame on a generally longitudinal base post pivot axis intermediate of the longitudinal axes adjacent the inner ends of the upper and lower members; means coupled to the main frame for suspending each boom in operative position extending laterally from the main frame and permitting the upper and lower members of each boom to pivot relative to the main frame; and means between the main frame and each boom for independently raising each boom relative to the main frame by pivoting the base post of the respective boom about its base post pivot axis and pivoting the associated boom about at least one of the longitudinal axes adjacent the inner ends of the upper and lower members of the boom.
