  • Publication number: 20220330484
    Abstract: A haymaking machine has a rake rotor with frame and support arm provided with a base part and a sliding part. The base part is pivotably connected to the frame about a support arm axis to enable the support arm to pivot between a lowered active position and a raised passive position. The sliding part is slidable relative to the base part between an inner position and an outer position for length adjustment of the support arm. The outer position is farther removed from the support arm axis than the inner position. A catching element is connected to the sliding part. A linear drive is connected to frame and sliding part to move the sliding part into the inner position and pivot the support arm from active position into passive position. A retaining mechanism holds the support arm in active position until the sliding part has reached the inner position.
