Abstract
A farm machine and particularly a mower or harvester, which includes a load-lightening and lifting device having an elastically deformable element mounted parallel with a jack or lift cylinder. According to the invention, the farm machine includes a piston which is separated from a rod of the jack and the rod includes a stop against which the piston is intended to come to rest, such that in a first mode of operation (during work), the rod can slide in the cylinder without a stop of the rod touching the piston, which allows a normal operation of an elastically deformable element. In addition, in a second mode of operation (during transport), the piston is brought into contact with the stop of the rod under the action of the fluid of a feed source, to displace the rod in relation to the cylinder.
