A soil cultivating machine such as a plow comprises a share followed by a soil guide which is in the form of a moldboard made up of power driven rotary guide elements. The elements are elongated and are all driven from a common shaft which can include a change-speed device to enable the rotary speed of the elements to be changed. The form of the guide can be altered by adjusting the relative angularities of the elements and the elements can be rotated at different speeds. The elements preferably extend less horizontally from front to rear where they are substantially vertical. An overhead frame beam interconnects the rear of the guide to a pivot on a trestle coupling. Also, the rear of the machine can be supported by a furrow wheel and a ground wheel on one side of the trestle supports the front of the machine.
A soil working machine comprising a frame with coupling means attachable to a prime mover and at least one tool, said tool having a guide for displaced soil, said guide comprising rotatable guide elements positioned one behind the other successively to receive and guide the displaced soil, said elements being mounted to rotate about respective axes and driving means connected to rotate said elements, said driving means including a change speed transmission and being connectable to a source of power, said transmission being located adjacent one end of said guide, said elements having ends supported by supporting means extending in the direction of the machine's travel, said supporting means interconnecting said ends and being so constructed and arranged that said ends are angularly adjustable relative to one another about a longitudinal axis that also extends in the direction of machine travel.
