ABSTRACT:
A discing tool is provided which includes a plurality of disc gangs connected to a movable elongated frame. The frame is supported on a number of rotatable wheel assemblies so that the disc gangs can be moved in a direction generally parallel to the longitudinal axis of the frame as well as in a direction generally perpendicular to the longitudinal axis of the frame. A pair of outer disc gangs are pivotally connected at their first ends to the center portion of the frame. The second ends of the outer disc gangs extend in opposite directions and the outer disc gangs can be positioned at various predetermined angles relative to the frame. A center disc gang is connected to the center portion of the frame and is vertically pivotal. When the discing tool is used to work the soil, the center disc gang disc harrows the section of soil between the first ends of the outer disc gangs. When the discing tool is transported, the center disc gang is postioned above the frame while the outer disc gangs are positioned adjacent the frame and substantially parallel thereto.
