A vehicle-borne spray boom apparatus has multiple articulated sections that are foldable and individually supported with respect to the ground to maintain a consistent and optimal distance between the boom sections and the ground on hilly and uneven terrain. A center section of the boom is mounted on a forward facing frame element of the vehicle, and boom arms extending from either end of the center section each comprise at least first and second sections, each supported by a ground-engaging wheel. Each first section is coupled at one end to the center section to permit vertical inclination with respect to the center section, and each second section is coupled at one end to a respective first section to permit vertical inclination with respect to such first section. The coupling between the central and first sections additionally permits relative horizontal inclination, and releasable latch mechanisms are triggered upon full horizontal extension of the first sections to maintain proper alignment between the first and center sections.

1. An articulated boom supported by a vehicle and configured to spray a liquid product on a ground surface in proximity to said vehicle, the boom comprising:a central section rigidly secured to a mounting plate on a leading face of said vehicle, and having first and second ends extending laterally in opposite directions from said mounting plate; a pair of first boom sections supported by first ground-engaging wheels and coupled to opposing ends of said central section by a pair of first coupling mechanisms that permit both vertical and horizontal inclination of said first boom sections with respect to said central section; and releasable latch mechanisms for maintaining full horizontal inclination of said first boom sections with respect to said central boom section when said boom is in a deployed state.
