摘要:
An agricultural mowing machine comprises a frame (3) having a coupling device for coupling the machine to a tractor. A carrying arm (7) is pivotally connected to the frame (3). A first hydraulic cylinder (17) is configured to pivot the carrying arm (7) relative to the frame (3). A lateral displacement structure is connected to the carrying arm (7) in such a manner that the lateral displacement structure can be displaced relative to the carrying arm (7) in a lateral direction between an inner position and an outer position. A second hydraulic cylinder (19) is configured to move the lateral displacement structure relative to the carrying arm (7). A mowing unit (5) is connected to the lateral displacement structure. The mowing unit (5) can be moved between an approximately horizontal working position, a raised headland position, and a transport position. The first hydraulic cylinder (17) and the second hydraulic cylinder (19) are connected to each other in such a manner that when the mowing unit (5) is in its transport position and the first or second hydraulic cylinder (19) is actuated by means of pressurized hydraulic fluid, hydraulic fluid discharged from said first or second hydraulic cylinder (19) is supplied under pressure to the other of the first or second hydraulic cylinder (19) for pivoting the carrying arm (7) so as to move the mowing unit (5) from the transport position towards the headland position displacing the lateral displacement structure outwards relative to the carrying arm (7) simultaneously.La présente invention concerne une faucheuse agricole qui comprend un châssis (3) comportant un dispositif de couplage pour coupler la machine à un tracteur. Un bras de support (7) est raccordé de façon pivotante au châssis (3). Un premier vérin hydraulique (17) est configuré pour faire pivoter le bras de support (7) par rapport au châssis (3). Une structure de déplacement latéral est raccordée au bras de support (7) de sorte que la structure de déplacement lat
