ABSTRACT:
A haymaking machine comprises a sub-assembly provided with two rake members, the sub-assembly being connected to a frame for pivotal movement about a pivotal axis that slopes upwardly to the rear. The center of gravity of the sub-assembly is ahead of such axis and a locking mechanism is provided for retaining the sub-assembly in a required working or transport position with respect to the frame. The disposition of the center of gravity and the pivotal axis is such that, when the locking mechanism is released, lifting machine above the ground causes the sub-assembly to swing automatically about the pivotal axis towards a transport position. If the machine is lifted more, the sub-assembly then swings automatically towards the working position.
