Abstract
Folding spray implements and agricultural work vehicle equipped with folding spray implements are provided. In embodiments, the folding spray implement includes a centerframe assembly, boom assemblies mounted to opposing sides of the centerframe assembly, and an actuation system coupled to the centerframe and boom assemblies. The boom assemblies include, in turn, inner wings pivotally joined to the centerframe assembly for rotation about frame-to-wing fold joints, as well as outer wings pivotally joined to the inner wings for rotation about wing-to-wing fold joints. The actuation system selectively transitions the folding spray implement: (i) from a stowed position in which axes of wing-to-wing fold joints extend principally in horizontal directions; (ii) through an intermediate unfolded position in which the axes of the wing-to-wing fold joints extend principally in vertical directions; and (iii) to a deployed position in which the axes of the wing-to-wing fold joints extend principally in horizontal directions.
