Abstract
A folding spray boom assembly includes an outer boom pivotally connected by hinge structure to an inner boom which is carried by support structure on an agricultural sprayer. An upper support rod is connected to the support structure and to the outer boom at a position offset from the pivotal axis of the hinge to arm, in effect, an over center device utilizing the tension in the support rod to maintain the spray boom assembly in its respective folded or unfolded positions without a latch or retaining pin. Relocating the support rod on the outer boom relieves stresses on the hinge when the boom assembly is in the unfolded position.
