Spike harrow tooth and method of manufacture

A method of cold forming a spike harrow tooth, comprising the steps of:

• providing a carbon steel metal blank of generally square bar stock, the blank having a length for a single harrow tooth;
• placing the blank in a first press oriented with opposite edges of the square configuration aligned in the direction of press closing and opening, the first press being equipped with dies for displacing metal from opposite side edges of the square at one end of the blank for partially forming a point with outwardly bulging excess portions;
• closing and opening the first press to partially form said point with said outwardly bulging excess portions;
• placing the partially formed blank in a second press again with said opposite edges of the square configuration aligned in the direction of press closing and opening, the second press being equipped with dies for removing said outwardly bulging excess portions;
• closing and opening the second press to completely form the point at said one end of the blank;
• and
• providing one of said first and second presses with generally flat dies for flattening at least one of said opposite edges to thereby displace the metal crosswise to enlarge the blank at the other end of the blank and for an enlarged head in a single operation with the step performed at the one press.
