Abstract:
Method of heat treating cultivating disc, coulter or grain drill blades made from heat quenched boron steels, such that they can be re-edged and re-sharpened using rollers, and yet retain excellent toughness, hardness and wear characteristics. The invention also includes the cultivating disc, coulter or grain drill blades made from boron steel, which have been heat treated according to the inventive method, such that can be re-edged or sharpened using pinch rollers. The cultivating blades are especially useful in the dry, sandy soils such as found in the wheat growing regions extending from central Kansas down into Texas.
