ABSTRACT:
A soil cultivating machine has side-by-side working members mounted on upwardly extending shafts that extend slightly forward with respect to the direction of travel. Each working member includes radial arms and at the outer end of each arm a tool, such as a disc or group of tines, is journalled for free rotation about a corresponding axis of rotation that extends at an angle with respect to the axis of rotation of the working member. During operation, the tools have portions that contact the ground and cut across the soil while rotating about the tools' axes of rotation and that of the working member. Such movements assist to propel the machine forwardly.
