ABSTRACT:
A furrow/ditch cleaner has a rotating wheel with elongate blades that contact the obstructing matter in the eye of the furrow and move the obstruction to the side of a field row. The blades are secured on radial arms attached to the central shaft of the wheel. The wheel is towed by a farming implement causing the blades to enter the furrow and move across the bottom of the furrow. The distance between the blades and their extension from the central shaft is adjusted by extending the length of the telescoping arms. A ditch cleaning member is secured to distant ends of each blade, encircling the blades a distance from an end of each blade. The ditch cleaning member moves along a transverse ditch compacting soil and debris in the ditch and leveling the ditch for the water flow.
