ABSTRACT:
An implement has a row of soil working or cultivating members that are driven to rotate about upwardly extending axes. Adjacent cultivating members are rotated in relative opposite directions to work overlapping circular paths and depend from an elongated frame portion that extends transverse to the direction of travel. Between neighboring cultivating members, soil crumbling members are positioned to work the top soil adjacent the overlapping paths defined by tines of the cultivating members. Each cultivating member includes a substantially horizontal support with tines depending from that support. The crumbling members extend from a forward supporting structure, rearwardly to free ends that normally are located above or adjacent the cultivating member supports, but below the frame portion. The crumbling members are resilient and/or spring mounted and can be used in combination with forward soil working elements that also extend rearwardly to the ground during operation.
