  • Patent number: 5862764
    Abstract: A method and apparatus for a harrow is provided, and more particularly to a harrow implement with a terrain following frame, able to be pulled by a tractor. The improved harrow includes a main frame that supports at least a floating frame on which harrowing blades are attached. The harrow blades follow the contours of a field or bed of soil, resulting in greatly improved tilling when compared to conventional apparatus used for this purpose. The harrow specifically suits the needs of a reduced tillage farming operation. The harrow is wide, yet the floating frames follow irregular surface contours, significantly improving the potential range of topography that can be farmed efficiently. The harrow can include a clod diverter to move or deflect clods to the irrigation furrows, away from the planting rows. It can also be customized in the field to handle the individual field's requirements, including tilling depth and seed row separation distances.
