ABSTRACT:
A cultivating implement has a row of soil working members that rotate about corresponding upwardly extending shafts that are driven by a common driving transmission. Each soil working member is independently connected to the implement frame by a linkage that permits pivoting to avoid an obstacle. Each member includes a horizontal arm with a stub shaft at each end of that arm and a tool that freely rotates about its respective stub shaft when the tool's tines contact the ground. The soil working members are mounted in a row that extends transverse to the direction of implement travel. A supporting roller is adjustably connected to the frame parallel to the row and can be used to regulate the working depths of the tines.
