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.
A soil cultivating implement assembly comprising two elongated frame portions linked to one another with a linkage and said portions each extending transverse to the direction of travel, a leading frame portion supporting a front row of rotatable soil working members that are driven to rotate about corresponding upwardly extanding shafts, a trailing frame portion mounting a rear row of soil working tools journalled in said trailing frame portion to rotate about respective upwardly extending axes, driving means connected to positively rotate said working members and said tools, the distance between the axes of rotation of neighboring tools being substantially equal but different from the distances between neighboring shafts of said soil working members, said row of working members and row of tools being positioned one behind the other to successively work the ground, coupling means on said assembly being connectable to a prime mover and ground supporting wheels being interconnected to said assembly, the axes of rotation of said ground wheels coinciding with one another and said wheels being positioned adjacent the lateral outer sides of said linkage, between the two frame portions, at least one of said tools comprising an elongated substantially horizontal tine carrier that is angularly displaceable about its own longitudinal axis against resilient opposition, said carrier extending with its longitudinal axis substantially perpendicular to the axis of rotation of the corresponding tool, said carrier being retained in a connector housing and elastically resilient material being positioned between the housing and said carrier.
