    Federzahngerät   
Die den Gegenstand der vorliegenden Erfindung bildende Neuerung und   Vervollkommnung   an Federzahngeräten, hauptsächlich Kultivatoren, besteht darin, dass   auf den Messerenden   der   Federzähne   hochstehende   Yorschneidemesser   angebracht werden, denen eine geeignete verschiedene Gestaltung gegeben werden kann. Solche   Vorschneidevorrichtungen sind zwar bereits     bei Federzahngeräten   dadurch geschaffen worden, dass man dem Schar in der   Mitte   eine schneidende Kante gab, indem man eine kantige Wulst einpresst, das Schar keilförmig ausbildete, oder durch   Verdrehung des Schars   eine schneidende Kante   schuf.   



     Diese Vorrichtungen haben   den Nachteil, dass sie nicht oder sehr schwer zu schärfen sind

   In der   Zeichnung zeigt Fig. l als Beispiel ein Federzahngerät, welches   mit diesen neuen Vorschneidemessern versehen ist. während die übrigen Figuren die an den Enden der Federzähne angebrachten Vorschneidemesser in grösserem Massstabe darstellen, u. zw. in der letzt-

    Spring tooth device
The innovation and improvement of spring tooth devices, mainly cultivators, which is the subject of the present invention, consists in the fact that upstanding cutting knives are attached to the knife ends of the spring teeth and can be given a suitably different design. Such pre-cutting devices have already been created in spring-tooth devices by giving the coulter a cutting edge in the middle by pressing in an angular bead that made the coulter wedge-shaped, or creating a cutting edge by twisting the coulter.



     These devices have the disadvantage that they cannot be sharpened or are very difficult to sharpen
 EMI1.1
 Shares that are interchangeably attached to the ends of the spring teeth are interchangeable, interchangeable, and attached in such a way that the precutting knives and the shares are fixed to the spring clips with one and the same fastening.



   In the drawing, FIG. 1 shows, as an example, a spring tooth device which is provided with these new precutting knives. while the other figures show the pre-cutting knives attached to the ends of the spring teeth on a larger scale, u. between the last
 EMI1.2
 at the ends provided with threaded bolt lugs d, which reach through two in the share and two corresponding holes provided in the spring tooth a. By putting on and tightening the nuts f, the simultaneous fixing of the pre-cutting
