ABSTRACT:
A spray cultivator having a frame with unequal rigid side elements pivotally connects to define between pivots a parallelogram with opposite sides equal and parallel. The frame is fixed by a first side element to a lift bar of a prime mover for pulling the cultivator over level and non-level fields. The remaining three side elements comprise the remaining parallelogram sides and the free ends thereof extending downwardly and rearwardly beyond the pivotal connections of the parallelogram. A second side free end engages level and non-level field surfaces with a sliding shoe. A third side free end that is parallel to the fixed first side element supports a spray pipe and nozzle that is continuously perpendicular to a field's level and non-level surfaces at a constant height thereabove responsive to the field surface engagement and pivotal parallelogram connections of the frame side elements. A fourth side free end mounts a stop that engages the parallel second side free end for limiting excessive pivoting of the frame as the cultivator crosses abruptly uneven surfaces. Spray pipe and nozzle height, but not attitude is changeable by the lift bar. A chain stop is adjustable between fixed and pivotal adjacent side elements to limit excessive pivoting when lift bar is raised. A slotted pivotal connection in the fixed parallelogram side provides frame flattening for transportation but not in operation.
