ABSTRACT:
A soil cultivating machine has a frame and a rotor journalled in the frame, the rotor being an elongated rotatable carrier with a plurality of cultivating members mounted along the length of the rotor. To simplify manufacture, the rotor carrier has a plurality of projecting mountings that extend substantially parallel to the axis of rotation. Plate or sheet cultivating members are fastened to the mountings to extend substantially at right angles to the carrier. To ensure penetration into the soil, each cultivating member has a curved outer circumference and is of knife-formation. A portion of the member extends substantially parallel to the normal direction of rotation of the rotor and a further portion is bent-over at an angle to this direction. Viewed from the side, successive cultivating members at least partially overlap one another.
