PCT No. PCT/DK90/00021 Sec. 371 Date Sep. 20, 1991 Sec. 102(e) Date Sep. 20, 1991 PCT Filed Jan. 19, 1990 PCT Pub. No. WO90/07868 PCT Pub. Date Jul. 26, 1990.A machine for spreading, turning and raking together hay, straw and similar materials. The machine has rotors (65, 84) which are rotatable around substantially vertical axles and are provided with rake arms (67) which extend radially and substantially horizontally from the rotation axles (58) of the rotors (65, 84). A number of parallel rods (68) are connected to the outermost ends of the rake arms (67) which rods constitute a rake. The rotors (65, 84) have a guide device (79, 85) so the rake arms (67) may be turned a previously determined angle around their longitudinal axis so that the rods (68) may interact with or go free of straw crops laid out in a field area. The guide devices (79, 85) are adapted to be turned around the axles (58) of the rotors (65, 84), and the guide device of one rotor (84) may be turned into the opposite direction of work so that it is possible to guide the laying down of the material into single swathes (105 ), double swathes (102, 104) or into a middle tract (106). The machine has a threepoint suspension and is telescopingly adjustable with regard to the working width; and the angle between the direction of travel of the machine and a line between the rotational axles (58) of the rotors (65, 84) is adjustable to obtain the exactness of the deposition of the crops.
