1. A haymaking machine comprising:
a rake rotor comprising a frame;
a support arm comprising a base part and a sliding part, wherein the base part is connected to the frame so as to be pivotable about a support arm axis to enable the support arm to pivot between a lowered active position and a raised passive position, wherein the sliding part is configured to slide relative to the base part between an inner position and an outer position to effect a length adjustment of the support arm, wherein the outer position is farther removed from the support arm axis than the inner position;
a catching element connected to the sliding part;
a linear drive connected to the frame and to the sliding part and configured to move the sliding part into the inner position and to pivot the support arm from the active position into the passive position;
a retaining mechanism configured to hold the support arm in the active position until the sliding part has reached the inner position;
wherein the retaining mechanism comprises a retaining element adjustably arranged at the frame and configured to engage the base part in a locking position and release the base part in a release position.
