ABSTRACT:
A soil cultivating machine has a cultivating member that is driven to rotate about a support that defines a horizontal axis extending transverse to the direction of travel. Radial arms fastened to brackets along the length of the support in helical rows mount freely rotatable discs or strips at their outer ends and the discs or strips each comprise means that rotate about corresponding axes of rotation that are non-perpendicularly inclined to the horizontal axis. Each soil working means is positioned along the length of said support to successively work an adjacent strip of land and the axes of rotation of the discs or strips are inclined to one another.
