Patent ID: 7669784

Claim:
An agricultural sprayer implement comprising: a wheeled main body; a cantilevered boom extending from the wheeled main body to a cantilevered end, the cantilevered boom including a torsion resistant section extending between a proximal end and a distal end, a hinge including a first wing and a second wing, and an end section extending between a proximal end and the cantilevered end; the second wing of the hinge formed by a leading end brace of the end section adjacent to the proximal end of the end section; the first wing of the hinge formed by a trailing end brace of the torsion resistant section adjacent to the distal end of the torsion resistant section; the torsion resistant section including an upper member and a lower member terminating at the trailing end brace, the torsion resistant section further including a plurality of braces extending between the upper member and the lower member, the upper member positioned increasingly nearer to the lower member as the torsion resistant section extends from the proximal end to the distal end of the torsion resistant section, the lower member of the torsion resistant section including a non-dispensing cylindrical tube, the non-dispensing cylindrical tube and the upper member being generally centered along a common vertical plane of the cantilevered boom, and the non-dispensing cylindrical tube having an outside diameter greater than a maximum width of a transverse cross-sectional shape of the upper member; and a dispensing tube carried by the cantilevered boom for dispensing chemicals; wherein the cantilevered boom is moved from an extended orientation to a folded orientation by pivoting the end section relative to the torsion resistant section at the hinge between the torsion resistant section and the end section; wherein a torsional load is applied at the trailing end brace of the torsion resistant section by the end section when the end section is pivoted relative to the torsion resistant section to move the cantilevered boom from the extended orientation to the folded orientation; wherein at least a portion of the torsional load is carried by the non-dispensing cylindrical tube of the torsion resistant section; and wherein the end section does not include the non-dispensing cylindrical tube centered along the common vertical plane of the cantilevered boom.
