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.
Claims14
A soil cultivating machine comprising a frame and at least one soil working member mounted on said frame, said working member being notatable about an upwardly extending axis defined by a shaft and driving means connected to rotate said shaft, tool means being mounted on a support that is positioned outwardly from said shaft and said tool means being freely rotatable about a further upwardly extending axis defined by a second shaft, said second shaft being spaced outwardly a substantial distance from said first mentioned shaft and extending at an angle to the same, the upper end of said second shaft being located further from first mentioned shaft than the lower end thereof, and said tool means being passed across the ground in a circular path inclined to the horizontal during the operative rotation of the soil working member.
A soil cultivating machine comprising a frame and two soil working members rotatably mounted side-by-side on corresponding upwardly extending axes defined by respective shafts on said frame, driving means connected to rotate said shafts in relative opposite directions and said soil working members being positioned to work overlapping strips of soil, each soil working member comprising support means that extends outwardly from its respective shaft, and at least one tool that is freely rotatable about a further upwardly extending axis defined by a second shaft, said second shaft being journalled on said support means and spaced from said respective shaft, said second shaft extending at an angle to the first mentioned shaft and the upper end of the second shaft being located further from its corresponding axis than the lower end thereof, said tool being moved across the ground in a circular path inclined to the horizontal during the operative rotation of the soil working member.
