Abstract: A method of making a tillage blade by obtaining a generally circular sheet metal steel disc having an outer peripheral edge. Waves are made in the outer peripheral edge of a circular steel disc in a predetermined pattern while the steel is cold. The outer peripheral edge is then sharpened at a predetermined acute angle with respect to a first plane by grinding. Then the disc is heat treated to make it harder so it will wear longer. If it is desired to have a concave/convex disc, instead of a coulter, then during the heat treating process the disc is deformed so that the sharpened portions of the peripheral edge remain generally in the first plane but a central portion of the disc is disposed at least partially in a second plane which is parallel to but spaced from the first plane.

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.

Abstract: A coulter or disc having a plurality of directional notches therein is used in one rotational direction for one use and an opposite rotational direction for a different use. The notches are selected from many arcuate shapes and sizes. The notches taper from sharp to dull from one end to the other, but in use one can chose to lead with the dull or the sharp end of the notches. A method of making and using such coulters or discs is described and shown.

Abstract: The present invention provides a wavy coulter having a plurality of variable-amplitude waves, each wave defined by a crest and an adjacent valley. The coulter is mounted on an implement such that a leading peripheral edge of the coulter rotates in a downward direction as it enters the soil. The waves having larger amplitudes of deviation from flat provide a driving force for turning the variable wave coulter. The waves having smaller amplitudes of deviation from flat provide penetration into the soil. The result is a coulter that is forgiving in both wet and dry soil conditions.

Abstract: An anhydrous ammonia knife including a shank attached to an implement tool bar, a knife segment attached to the forward edge of the shank, and an ammonia delivery tube disposed between the forward edge of the shank and the leading edge of the knife segment. The knife selectively penetrates the soil to a predetermined depth and the tube discharge end is disposed in fluid communication with the soil. Ammonia is discharged into the soil at a position immediately behind the leading edge of the knife segment as the furrow is first opened. This positioning minimizes the amount of ammonia vapor lost to the atmosphere since the ammonia is quickly entrapped in the soil.
