ABSTRACT:
An implement assembly includes two elongated frame portions with respective coupling members that are linked to one another. Either frame portion can be leading or trailing and in a preferred arrangement, the leading frame portion has tined soil working members that work overlapping strips of top soil while the trailing frame portion has tined tools that work subsoil in non-overlapping paths. A common transmission can be fixed to either respective gear box that rotates the members and the tools. In either arrangment, the transmission is connected to the driving gears for both the members and the tools which can be rotated at different speeds from that of the members. A ground engaging wheel can be positioned at either side of the center of the assembly to bear on ground that is located between neighboring tools and/or members. The member can work paths of soil having different widths from those of the tools. The tools can be formed of horizontal carriers that are resiliently mounted in connectors with elastic elements that are located within a housing surrounding each carrier.
