Agricultural apparatus for distributing material, such as fertilizer or pesticide, to a field, characterized by apparatus adapted to be affixed to a conventional vehicle, such as a truck, and including a pivoted boom extending outwardly from each side of the vehicle, a fixed spray tube or the like extending across the rear end of the vehicle, and caster mounted markers carried by each boom at its outer end for marking the edges of a path over which material is delivered by the booms and fixed spray tube. Each boom is mounted for major pivotal movement about an axis extending upwardly and forwardly with respect to the direction of movement of the vehicle, the angle being of the order of 40°to 60°, which permits the booms to swing rearwardly and upwardly when a marker passes over an obstruction, such as a rock. Each boom is also pivoted for minor movement about a second axis disposed perpendicular to the axis of major pivotal movement and a resilient strut limits the movement about the second axis.

Agricultural apparatus for use with a vehicle for delivering a material, such as a fertilizer or pesticide, along two parallel spaced field paths, one at each side of the vehicle and along another parallel central path therebetween, and for marking the outer edges of the entire path on the field so that upon the next pass of the vehicle across the field a like entire path may be supplied with the material without substantial voids or overlaps of delivered material, comprising: a. a pair of boom support members, each being rigidly affixable to an opposite side of the vehicle and between its ends, b. each boom support member being mounted for major pivotal movement about a first axis lying in a substantially vertical plane adjacnet one side of the vehicle and disposed at a forwardly and upwardly median acute angle of the order of 40°to 60°relative to the forward direction of the vehicle, c. a boom supported by each of the boom support members with means securing the inner or proximate end of each boom to its support member for minor limited pivotal movement about a second axis substantially normal to said first axis, d. a field marker carried by the outer end of each boom constantly supporting each end against downward gravitational movement and as limited by the depth of a continuous furrow formed thereby in the soil, e. each marker being so constructed to engage an obstacle in the soil, such as a rock or the like, and pass over same, swinging the boom about said first axis in a rearward and upward direction about said first axis, the boom swinging forwardly and downwardly to its normal operative position after the marker has passed over the obstacle, said second axis permitting minor swinging of the boom thereabout independent of movement thereof about said first axis, f. each marker being caster mounted to the end of its boom for free rotation about a substantially vertical axis and disposed rearwardly of its caster axis to permit it to pivotally trail the boom and follow a curved path equidistant from a curved path of the vehicle, g. fixed material distributing means rigidly affixable to the rear end of the vehicle substantially parallel to the booms and of a length substantially that of the distance between the inner ends of the booms for distributing the material to said central path, h. said first axes permitting the booms to be swung to transport positions substantially normal to their operative positions in which they are disposed at upwardly and rearwardly angles of said 40°to 60°.
