ou autres machines agricoles analogues.

  
Cette invention a pour objet des perfectionnements aux dents élastiques pour herses on autres machines agricoles analogues.

  
Selon l'invention, les dents sont agencées de façon à pouvoir pivoter individuellement à l'encontre d'un ressort de rappel par rapport à l'arbre sur lequel sont rangées ces dents en nombre plus ou moins grand. Grâce à cet agencement, chaque dent

or other similar agricultural machinery.

  
This invention relates to improvements to resilient teeth for harrows and other similar agricultural machines.

  
According to the invention, the teeth are arranged so as to be able to pivot individually against a return spring relative to the shaft on which these teeth are arranged in greater or lesser number. Thanks to this arrangement, each tooth
