<p>An agricultural or forestry machine has a hydraulically operated (16) device (31) that rotates about an axis (19). The axis of rotation and the support bearing (13') axle (13) form the base (3) of an articulated parallelogram (18) consisting of a swing arm (27), side arm (32) and link-lever (27). The hydraulic cylinder and piston unit (16) are coupled to the hinge (17) and the side-arm.</p> |
