ABSTRACT:
A cultivator frame assembly particularly adapted for cultivation of bed-planted crops comprises a parallelogram linkage frame adapted to be attached to a conventional tool bar and a bed cultivator frame carried by the parallelogram linkage frame. The bed cultivator frame provides a series of longitudinally spaced tool bars for mounting the gauge wheel and such cultivating tools as will properly cultivate the multiple crop rows of each bed. The two frames are readily detached so that various forms of the bed cultivator frame may be employed with the common parallelogram linkage frame, as need arises.
