An improved agricultural spray boom having a primary section, a secondary section and a break away section is provided. The primary section has a top extrusion having a web and two tubes, each tube having a heat sink and a wing. No welds are located above the centerline of the tubes where stress would be the greatest. The secondary section is pivotally attached to the primary section. Weight of the second section and break away section cause a twisting force to be applied to the primary section. The primary section has specially oriented side braces which act in compression to resist the twisting force. The primary section further has a steel connector connected to the underside of the extrusions (and not welded to top of extrusions). The secondary section also has a top extrusion with a web and two tubes.
