ABSTRACT:
An extendible, collapsible spray drawbar device is disclosed comprising a triangular shaped frame structure adapted at the forward apex end for pivotal attachment to a prime mover and having wheels at the rear base end, transverse spray bar elements pivotally mounted to and extending from the base of the frame structure, wheels pivotally mounted to the outer end of the spray bar element, extension bar elements hingedly mounted to the outer end of the spray bar elements, and support elements pivotally mounted at one end to the transverse spray bar element and pivotally mounted at the other end about a horizontal and vertical axis to a brace member transversely extending across the triangular shaped frame structure. During the spraying operation, the transverse spray bar elements and the extension bar elements extend linearly from the base of the triangular shaped frame structure. For transportation, the support elements detach from the transverse brace and pivot toward the transverse spray bar element, the transverse spray bar elements and extension bar elements pivot rearwardly to a position approximately perpendicular to the base of the triangular shaped frame structure, and the wheels of the transverse spray bar element pivot 90.degree. so as to be parallel to the wheels of the frame structure. The operational position of the spray drawbar provides spray bar reach across many rows while the transportation configuration provides an implement having a width generally less than the wheel span of a prime mover.
