Agricultural device with an actuator between two hanging work units

An agricultural device comprising:

• a first work unit and a second work unit, the device being able to occupy a work configuration, in which each work unit rests at least partially on a ground, and a transport configuration, the device being connected to a chassis that is mounted on or integrated into a tractor vehicle moving in a direction of advance;
• and
• a support arm pivotally mounted on the chassis around a lift axis substantially parallel to the direction of advance and around which the device is pivoted to reach the work and transport configurations,
• each work unit comprising a plurality of plant processing elements and extending in a respective longitudinal direction that is transverse to the direction of advance at least in the work configuration,
• each work unit being pivotally mounted relative to the support arm around a connecting axis that is transverse relative to the corresponding longitudinal direction, each work unit comprising a respective guided end and a respective free end further away from the corresponding connecting axis than the corresponding guided end,
• wherein the agricultural device comprises a central actuator consisting of a central cylinder, rigidly fastened to at least one of the first and second work units and connected to the other of the first and second work units such that the central actuator is configured to apply on each of the work units, at least in the work configuration of the device, a biasing force opposed to a downward pivoting movement of its free end around the corresponding connecting axis.
