Abstract: The present invention relates to an agricultural haymaking machine comprising a chassis resting on the ground by at least one wheel and intended to be coupled to a tractor able to move the machine in a direction of advance, a carrier carrying a plurality of rotors being swivel mounted to the chassis around a central pin oriented transversally to the direction of advance, each rotor being driven around a respective drive axis, and a lift actuator, articulated to the chassis on one hand and to the carrier on another hand, being able to make the carrier pivot around the central pin relative to the chassis, the machine being able to adopt a headland configuration in which the carrier is raised, as well as a work configuration in which the carrier rests on the ground by means of at least one support. The central pin is rigidly attached to the carrier, and the machine comprises a positioning actuator able to move the central pin relative to the chassis to change the position of the drive axes relative to the ground.
