Systems and structures for elongate boom mounting, deploying and recovery for agricultural equipment, such systems mountable either at the front or rear end of a powered or towed vehicle; mounting masts and frame structures associated therewith for pivotally mounting elongate booms on mobile equipment in deployable and recoverable fashion, such utilizing manual operator power rather than power cylinders and the like; a frame for mounting elongate booms including a pair of rearwardly inclined boom support members, a pair of transverse upper and lower beam members connecting the upper and lower ends of the boom support members and a pair of horizontal, spaced apart, forwardly extending axial beams each connected to an upper end of one of the boom support members, sets of cables coupling the booms with the frame members, the inner ends of the booms pivotally mounted on the lower ends of the boom support members.

Spray apparatus for use on a vehicle adapted to be pulled or driven over the surface of a field to be sprayed, said spray apparatus adapted to deliver a liquified material along to said substantially parallel, spaced apart, elongate field paths, each said path oriented substantially normal to the line of motion of the vehicle and one of said paths positioned on each side of said vehicle, said vehicle having front and rear, spaced apart ends and opposed, spaced apart, substantially parallel side thereto, a pair of structural boom support members, each rigidly affixed with respect to an opposite side of the vehicle and positioned behind the rear end thereof, each said boom support member being mounted with respect to said vehicle in a fixed position lying in a substantially vertical plane substantially paralleling the side of said vehicle and disposed at a rearwardly inclining angle from the vertical of approximately 15 degrees to 35 degrees, an elongate, normally straight boom having an inner end and an outer end pivotally mounted on each said boom support member close to the lower end thereof and adjacent to the inner end of said boom and adapted to be swung from a first, substantially level, ground paralleling position substantially normal to the longitudinal axis and direction of travel of said vehicle to a second, upwardly angled position along the side of said vehicle substantially paralleling the said side and direction of travel of said vehicle, in a forwardly directed orientation, the inboard end of each boom being pivotally mounted in one end of a yoke, said yoke fixed at the other ends thereof to a collar rotatably mounted at a fixed level adjacent the lower end of a boom support member, a frame positioned on said vehicle behind said rear end thereof and rigidly fixed with respect to said vehicle rear end, said frame including means carrying and supporting said two boom support members in rigid, spaced apart relationship to one another adjacent to said vehicle rear end and said frame including two normally horizontal, transverse, substantially parallel, vertically spaced apart beam members, said transverse beam members rigidly connecting together and spacing apart the upper and lower ends of the boom support members with respect to one another, said frame also including a pair of substantially horizontal, spaced apart, substantially parallel axial beams, one such axial beam rigidly connected to and extending forwardly from the upper end of each of the boom support members in substantial relationship with the adjacent vehicle side, said frame also including such additional internal frame structural members as to fix the said boom support members, transverse beam members and axial beams in a rigid, integral structural array at the rear of said vehicle, two opossed, first rearwardly positioned cable means, one such first rearward cable means resiliently coupling each said boom intermediate the ends thereof by an outboard end of said first rearward cable means with the substantial midpoint of the upper transverse beam member of said frame by an inboard end of said first rearward cable means, a resilient spring positioned in each first rearward cable means at the inboard end thereof, means for limiting the outward resilience of each said spring comprising a cable loop check on the inboard portion of each said first rearward cable means, said loop checks encircling forwardly extending portions of said frame positioned inboard of said boom support memebers, whereby when said booms are moved forwardly for stowage, the first rearward cables will cause the free ends of said booms to rise upwardly, the booms maintained in their upward position by said first rearward cables, two opposed second, forward cable means, one such second forward cable means coupling each said boom intermediate the ends thereof by an outboard end of said second forward cable means with one of an axial beam member of said frame and a portion of said vehicle itself at a position substantially forwardly, with respect to said frame, of said boom support member upper ends by means of the inboard end of said second forward cable means, each second, forward cable means being removably connectible to one of the axial horizontal beams at a forward position thereon for lateral beam extension, means on each side of said vehicle positioned forwardly of the said second, forward cable means connections to said frame for removably engaging an outboard portion of the boom on that vehicle side for supporting same in a stowage, transport position substantially parallel to said vehicle side and extending upwardly at an angle from approximately 15 degrees to 35 degrees from the horizontal, as well as forwardly on said vehicle, and rotatable wheel means connected to said booms outboard of said first and second cable connections thereto and extending downwardly from said booms substantially normal to the longitudinal axes thereof whereby to support said booms above ground level in substantially horizontal orientation in spraying use.
