ABSTRACT:
A folding boom for agricultural sprayers comprising a center frame section mounted in the bed of a truck on a trailer. First and second boom assemblies normally extend outwardly from the center section with each of the first and second boom assemblies comprising inner, intermediate and outer boom sections. The inner boom section is connected to the center frame section so that the inner boom section will pivotally move rearwardly if the inner boom section strikes an obstruction. The inner boom section is also connected to the center frame section in such a manner so that the inner boom section may be freely pivotally moved to a transport position. The intermediate boom section is pivotally connected to the outer end of the inner boom section so that the intermediate boom section may pivot rearwardly relative to the inner boom section if the outer or intermediate boom sections strike an obstruction. The outer boom section is pivotally connected, about a horizontal axis, to the outer end of the intermediate boom section so that the outer end of the outer boom section is pivotally moved upwardly if either the intermediate or outer boom sections strike an obstruction. The outer end of the outer boom section is also pivotally moved upwardly if the inner boom section moves downwardly relative to the center frame section. The outer boom section may be folded upwardly over the intermediate section for transport purposes and the intermediate boom section may be folded rearwardly relative to the inner boom section for transport purposes.
