Abstract
Abstract A main frame is supported, adjacent its rear end, by a pair of wheels, and the front end of the main frame is arranged for connection to the coupling pin of either a conventional tractor, preferably having a power take-off, or of a separate traction and steering assembly. An independent motor on the main frame drives rotatable ground-engaging agricultural implements supported on the main frame. These implements, when rotated by the independent motor on the main frame, are operable to work the soil, and develop with the soil, a thrust force tending to drive the main frame at a first speed determined by the reaction of the soil. The independent motor on the main frame is more powerful than the power take-off of the associated tractor or of the motor driving the separate traction and steering assembly. The connection of the main frame to the coupling pin serves to transmit a reaction force between the main frame and the steering and control mechanism. The motor of the tractor or control and steering assembly is independent of the motor on the main frame, and constitutes the sole driving means for the wheels of the tractor or the steering and control mechanism, and tends to drive the tractor or steering and control mechanism at a second speed. The relative speed due to the first and second motors causes a reaction force to be transmitted through the connection coupling the main frame to the tractor or steering and control mechanism, to counteract increases and decreases in the thrust force exerted by the rotating agricultural implements. The main agricultural implement is a rotary hoe carrying laterally projecting tines, and divided into two sections which may be swung to a horizontal position, to extend to either side of the main frame, or to a vertical position, for compactness during transport along a highway or road. Other agricultural components on the main frame may include tanks containing soil treating materials, distributing means connected to these tanks, and other ground working implements.
