Improvement for agricultural machines in particular for haymakers.

摘要

The present invention relates to an agricultural machine intended particularly for haymaking, possessing a chassis which carries a plurality of rotors and which is produced 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 possible to neutralise said articulation when the machine is free of the ground. Furthermore, a lock for blocking the stop device during transport is provided. It is notable in that connected to the lock (44) are operating means (49) which extend into the vicinity of a lateral part (7 or 8) of the chassis (1) and which are actuated by this lateral part (7 or 8) or the corresponding hydraulic jack (25 or 26) when said lateral part is displaced upwards into the transport position.
