Abstract

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.
