ABSTRACT:
The invention relates to a machine for working grass, hay or other crops on the field, provided with two rake members which are drivable about upwardly directed axes of rotation. During operation, the distance between the rake members can be changed by controls at the seat of the tractor on which the machine is mounted to adapt the machine to various circumstances. The machine is provided with swath forming crop guide members, the relative positions of which are automatically adapted to remain about the same irrespective of the distance between the rake members.
