Abstract

Cette invention concerne une machine pour le travail du sol telle qu'une charrue, avec système de réglage en hauteur d'au moins deux roues 36, 48 montées de façon à pouvoir pivoter verticalement sur le châssis de la machine. Ces roues et le dispositif de réglage de hauteur sont reliés entre eux de telle sorte que, lors du déplacement du châssis pour passer d'une position supérieure à une position inférieure, ce chassis bascule vers l'avant avec les outils 20, ce qui facilite la pénétration de ceux-ci dans le sol.
