| 摘要 |
The invention relates to an agricultural implement, and particularly a mower, including a lightening (load relief) and lifting device consisting of an elastically deformable element mounted in parallel with a cylinder actuator (jack). According to the invention, the agricultural implement is characterised in that the piston (54) is not attached to the rod (52) of the cylinder actuator (46), and that the said rod (52) includes a stop piece (62) against which the piston (54) is intended to come to bear, so that: - in a first operating mode (237, 238), the rod (52) can slide in the cylinder without the stop piece (62) of the said rod (52) touching the piston (54), which allows a normal operation of the elastically deformable element (45), and - in a second operating mode, the piston (54) is brought into contact with the stop piece (62) of the rod (52), under the action of the fluid of a supply source, so as to move the said rod (52) with respect to the cylinder (51). <IMAGE>
