Abstract: A hay harvesting machine including a frame with several windrowing rotors, the frame including a draft beam and a connecting beam which is articulated with respect to the draft beam, at least the rotor of the connecting beam located farthest back being equipped with a windrowing deflector. The machine includes a retractable stop for the movement of the connecting beam about its axis of articulation, and a device for shifting the deflector notably with respect to the corresponding rotor. A device controls the stop, which device is actuated by the shifting device. The stop prevents the connecting beam and the corresponding rotor from moving from a first work position into a second work position as long as the deflector can collide with the rotor which precedes it. When the deflector is shifted into a position where the risk of collision is eliminated, the stop is retracted and the change in position is possible.

Abstract: A haymaking machine having a chassis which is composed of a central section and several lateral sections which are articulated together and carry rotors. On each side of the central section four lateral sections are provided which are articulated together by axes extending in the direction of travel, the length of each first lateral section being at least equal to the distance between the support spindles of two adjacent rotors, the length of each second lateral section being substantially longer than the distance between the support spindles of the two adjacent rotors, the length of each third lateral section being substantially shorter than the distance between the support spindles of the first adjacent rotors, and the length of each fourth lateral section being at most equal to the distance between the support spindles of the two adjacent rotors.

Abstract: This invention relates to a haymaking machine which includes a frame having a central section and three lateral sections which are connected to one another and which carry rotors rotatably driven during working operation. The lateral sections can be folded for transport by hydraulic cylinders. On each side of central section there are located the three lateral sections, each of which includes a pipe and a housing equipped with a rotor. A hydraulic cylinder extends directly from the central section to each third lateral section and in the transporting position, the first and second lateral sections are directed upward and the third lateral sections are directed downward.

Abstract: A hay harvesting machine for windrowing hay, moving swaths of hay, tedding hay and the like includes at least one drum which has a base and a wall, and is rotatable about an axis which is inclined within a predetermined range to the vertical, a flexible skirt which has substantially the shape of a truncated cone, and is connected to the base for sweeping up the hay, and a plurality of arms arranged in a plurality of rows along the wall, and which extend therefrom so as to cooperate with the skirt for further movement of the hay, and wherein at least the arms of the row nearest to the skirt extend in a direction substantially parallel with an upper surface of the skirt.

Abstract: An agricultural machine for the tedding or conditioning of fodder comprises a pair of drums (1,2) rotatable about shafts (12,13) which are slightly inclined in the forwards direction of travel (A) of the machine. The drums (1,2) are interconnected by a chassis (3) which is connected to a coupling member (4) by a connecting beam (5). The coupling member (4) has attachment points (6,7,8) for coupling the machine to a tractor. Each drum (1,2) carries at its lower portion a flexible, deformable skirt (17,18) for grasping and transporting the fodder. The skirts are associated with tedding or conditioning means which may comprise ribs (20) on the upper surfaces of the skirts (17,18) or other means (not shown).

Abstract: An arrangement for gathering and lifting forage lying on the ground includes at least a carrier mounted on a support for rotation about an upright axis, a skirt mounted on the lower portion of the carrier, a receiving device, and a guiding arrangement extending between the skirts and reaching under the same and the receiving device. The forage lifted by the skirts may be transferred to the guiding arrangement by a roller which is situated at least partially underneath the skirt upstream of the leading end of the guiding arrangement. The guiding arrangement may include a guiding plate, a conveyor belt, or an elevator arrangement including a plurality of rakes. When two carriers with skirts mounted thereon are being used, the trajectories of the skirts slightly overlap one another, the skirt or skirts being flexible and having peripheral projections which reach between one another.

Abstract: An agricultural machine for tedding and windrowing fodder crops comprises a pair of drums (1,2) rotatable about shafts (12,13) and interconnectd by a chassis (3) which is connected to a coupling member (4) by a connecting beam (5). The coupling member (4) has attachment points (6,7,8) for coupling the machine to a tractor. Each drum carries at its lower portion a flexible, deformable skirt (17,18) for grasping and transporting the fodder. Means (19) are associated with each skirt (17,18) for carrying out tedding or windrowing. The means (19) may comprise drive means (20) which are movable into a first position for tedding and into a second position for windrowing. The drive means are pivotally mounted on the walls of the drums (1,2) and movement of the drive means between their two positions is achieved by means of a screw (35). Other means are disclosed in the specification for achieving tedding and windrowing.
