ABSTRACT:
A mower includes a frame having a connecting mechanism for connecting the frame to a motor vehicle. The mower also includes at least one harvesting mechanism which comprises cutting elements and is connected to the frame through a suspension device. The suspension device permits the displacement in height of the harvesting mechanism relative to the frame. The mower further includes a lightening device operatively connected to the harvesting mechanism and comprising at least one spring connected directly to the harvesting mechanism. The lightening device makes it possible to reduce the pressure with which the harvesting mechanism rests on the ground by transferring a part of the weight of the harvesting mechanism to the frame.
