ABSTRACT:
A folding cultivator is disclosed wherein first and second sets of downwardly extending teeth are attached to the rearwardly folding wing of the cultivator at spaced intervals along its length. The teeth are arranged so that teeth of one set are located on each side of a tooth of the other set. In addition, the distal ends of the teeth of one set are located forwardly with respect to distal ends of the teeth of the other set. When the wing frame of the cultivator is folded and unfolded to achieve transporting and operating configurations, respectively, the teeth of a central wing section and those of outer wing sections intermesh without entangling and damaging each other.
