ABSTRACT:
A soil cultivating implement has a row of tined soil working members that are driven to revolve about upwardly extending axes. The drive to the members includes meshed pinion gears and shafts of the members are mounted on every third pinion gear. The soil working members have tines, the inner ends of which are secured in recesses of plates near the axes of rotation of the working members. Each tine has an inner curved part and an elongated support portion to which downwardly, inclined soil working portions are integrally joined. The tines are free to deflect from their connections and neighboring soil working member tines work overlapping and/or adjoining strips of soil. The paths traced by the revolving tines spans a diameter that exceeds the width of two neighboring pinion gears.
