  • Patent number: 5813475
    Abstract: An agricultural sweep has a main body with a cutting edge including a tip and winged portions extending away from the tip. The tip and winged portions have hardfacing material on them. In the improvement, the width of the hardfacing material on the tip is greater than the width of the hardfacing material on the winged portions, thereby conforming the location of hardfacing material to a soil pressure gradient along the cutting edge. A new method for applying a hardfacing material to an agricultural sweep includes the steps of (a) determining a face pressure gradient resulting from soil passing across the face and applying hardfacing material to those portions of the face at which the gradient exceeds a predetermined value.
