Abstract: An agricultural machine comprises a frame which is adapted to be hooked to a drive tractor and carries at least one rotor equipped with work tools controlled by a central cam to move products such as hay which are on the ground. The rotor is connected to the frame by a pin which is positioned substantially perpendicular to the direction of advance of the machine and comprises a central support pin on which carrying wheels are connected. The agricultural machine further comprises an actuating mechanism positioned between the frame and the rotor of the machine which acts on the rotor to pivot the rotor around its hinge pin. With this arrangement, a partial load transfer from the front wheels onto the rear wheels or wheels can be obtained and the agricultural machine can adapt to the unevenness of the ground as well as clear all obstacles.
