摘要：The present invention relates to an agricultural machine intended particularlyfor haymaking, possessing a chassis which carries a plurality of rotors and which isproduced in the form of a central part and of lateral parts, the latter being vertically
displaceable by means of hydraulic jacks. Said central part comprises a connecting beam,on which is articulated a coupling bracket equipped with a stop device making it possibleto neutralise said articulation when the machine is free of the ground. Furthermore, alock for blocking the stop device during transport is provided. It is notable in thatconnected to the lock (44) are operating means (49) which extend into the vicinity of alateral part (7 or 8) of the chassis (1) and which are actuated by this lateral part (7 or 8) orthe corresponding hydraulic jack (25 or 26) when said lateral part is displaced upwardsinto the transport position.
