 Vermittlung eines Zwischenrades o auf das kleinere Zahnrad p übertragen wird, welcher an dem   Auf zughebe ! t   befestigt ist. 



   Die Aufzugfeder e ist bei beiden dargestellten   Ausführungsformen   derart angeordnet, dass sie das Niederdrücken des Fusshebels b vom Anfang der Bewegung an bis zur Beendigung der Bewegung unterstützt, und zwar ist der Winkel zwischen der Achse der Zugfeder e und der rück-   wärtigen   Verlängerung   d   des Fusshebels b, wenn sich der Schneidäpparat am'Erdboden befindet   (Fig, 1   und 3), am kleinsten und nimmt mit der Abwärtsdrehbewegung des Fusshebels b zu.

 EMI2.3 
   des ganzen Weges ausgeübte Drehmoment   annähernd gleich ist, so dass auch die   dem Führer   durch die Zugfeder geleistete Hilfe konstant ist und durch Wahl der Feder dafür gesorgt werden kann.

   dass die von dem Fahrer auszuübende Kraft nie die zulässige Grenze   überschreitet. Es   ist hiebei selbstverständlich, dass die Zugfeder e umso stärker gewählt werden muss, je   schwerer   der Schneidapparat der betreffenden Mähmaschine ist. 



   PATENT. ANSPRÜCHE :
1.   Mähmaschine mit Vorrichtung   zum   Hochschwenken des Schneidwerkes in   die Vertikal-

 EMI2.1
 Mediation of an intermediate gear o is transferred to the smaller gear p, which is lifted on the elevator! t is attached.



   The mainspring e is arranged in both illustrated embodiments in such a way that it supports the depression of the foot lever b from the beginning of the movement until the end of the movement, namely the angle between the axis of the mainspring e and the rearward extension d of the foot lever b, when the cutting device is on the ground (Fig, 1 and 3), smallest and increases with the downward rotation of the foot lever b.
 EMI2.2
 
 EMI2.3
   the torque exerted all the way is approximately the same, so that the help given to the guide by the tension spring is constant and can be ensured by choosing the spring.

   that the force to be exerted by the driver never exceeds the permissible limit. It goes without saying that the tension spring e must be selected to be stronger, the heavier the cutting device of the mower in question.



   PATENT. EXPECTATIONS :
1. Mower with device for swiveling the cutting unit up into the vertical
 EMI2.4
 During the entire rotation of the elevator lever, the foot lever remains in an easily accessible position for the driver.
