Abstract: An agricultural machine is coupled to a tractor vehicle and includes a work unit connected to a chassis relative to which the work unit can be moved, the machine being able to take up a work configuration and a transport configuration. The machine includes a lightening device having a lightening cylinder connected to the chassis by a flexible compression tie-rod on one side and to the work unit at a front articulation on the other side, the lightening cylinder being able to transfer, in the work configuration, some of the weight of the work unit onto the chassis, the flexible compression tie-rod being attached with the lightening cylinder at an anchoring point and with the chassis at a fastening point, a deflection system making it possible to move the lightening cylinder by pivoting the anchoring point about the front articulation so as to move it away from the midplane.

Abstract: The invention relates to an agricultural machine intended to be coupled to a tractor vehicle and comprising a work unit connected to a chassis relative to which the work unit can be moved, the machine being able to take up a work configuration in which the work unit rests at least partially on the ground and a transport configuration in which the work unit is raised from the ground. The machine comprises a lightening device having at least one lightening cylinder connected to the chassis on one side and to the work unit on the other side, the lightening cylinder being able to transfer, in the work configuration, at least some of the weight of the work unit onto the chassis.
