Simplified haymaking machine with a carrier

An agricultural haymaking machine, specifically a tedder, comprising a chassis resting on the ground by means of at least one wheel, the machine being coupled to a tractor able to move it in a direction of advance, the machine comprising a carrier bearing a plurality of rotors, the carrier being swivel mounted with regard to the chassis around a central pin oriented transversally to the direction of advance, each rotor being driven around a respective drive axis, the machine comprising a lift actuator articulated to the chassis on one hand and to the carrier on another hand and being able to make the carrier pivot in relation to the chassis around the central pin, 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 a support;

• wherein the central pin is rigidly attached to the carrier;
• wherein the machine comprises a positioning actuator making it possible to move the central pin relative to the chassis to change the position of the drive axes;
• and wherein a sliding guide is made in the chassis to guide the motion of the central pin relative to the chassis, the lower end of the sliding guide being further away from a straight plane orthogonal to the direction of advance and located in front of the sliding guide than its upper end.
