Abstract: The disclosure is of a haymaking machine with two or more rake heads, a chassis, and a beam, and also means which automatically and simultaneously cause a pivoting of the chassis of the rotary rake heads about a substantially horizontal spindle of a pivot when the said chassis is pivoted about a substantially vertical spindle of the said pivot to modify its orientation in relation to the direction of travel of the machine when the latter is changed from the central tedding position into the lateral windrowing position and vice versa.

Abstract: The disclosure is of, in a mower which works over a great cutter width and comprises cutter discs or cutter drums or cutter belt pulleys or other rotary elements involved in the cutting operation, at least one device for reducing the width of the windrows comprising an endless flexible windrowing member which travels around two drums having substantially vertical axes of rotation, the first of said drums being approximately above one of said rotary elements at one extremity of the mower, the second of said drums being spaced to the rear of and nearer to the middle of the mower so that the windrowing member follows a path at an acute angle to the cutting front, at least one of said drums being driven at a speed different from that of said rotary elements so that the windrowing member impels cut fodder from a margin towards the middle of the windrow.

Abstract: The disclosure is of a fodder mower-conditioner mounted laterally of a tractor and comprising two or more rotary-scythe cutters and one or more conditioning rotors all rotating about axes which as viewed from above fall within a horizontal plane of a width equal to and containing the horizontal diameters of the tractor rear wheel tires, the rear wheel tire which is nearer the mower-conditioner being nearer to the nearest cutter trajectory than to the nearest conditioning rotor bearing.

Abstract: The disclosure is of a haymaking machine with a rotary rake head and a control mechanism for adjustable tool-carrier arms which are mounted for pivoting in support bearings which are wedged between two covers, one of which is situated above the control mechanism of the tool-carrier arms and is fast with the drive hub of the rotary rake head, and the other of which is situated below the said control mechanism of the tool-carrier arms.

Abstract: The disclosure is of a haymaking machine with rotary rake heads and a chassis connected by a beam to a hitch device for coupling to a tractor three-point power lift, characterized in that the said connection beam is on the one hand pivoted at its forward end to the hitch device about a substantially vertical pivot spindle and on the other hand is fixed rigidly at its rear end to the support chassis of the rotary rake heads in such manner as to retain the said support chassis during operation in a position in which it constantly forms an obtuse angle with the direction of travel of the machine.

Abstract: A haymaking machine for central tedding and lateral windrowing has a pair of rotary rake heads carrying working tools. The tools are rotatively interconnected by means of a support chassis that carries a forwardly extending frame beam. The direction of rotation of the rotary rake heads automatically reverses when the relative position between the support chassis of the rotary rake heads and the frame beam is modified, thereby to transpose the machine from the tedding position into the windrowing position and vice versa.

Abstract: A haymaking machine for carrying out lateral discharge windrowing or central tedding, comprises a pair of rotary rake heads interconnected by a chassis. A control member causes the chassis to rotate about an axis parallel to the axis of the chassis. An intermediate element is articulated to the chassis about this axis and a beam extends between the chassis and a hitch device. The beam is articulated to the intermediate element about a vertical axis and is connected to the chassis.

Abstract: The disclosure is of a front deflector for a mower having cutter-carrying discs driven from beneath, the deflector having an edge to co-operate with a frustoconical element which it partly surrounds, said edge having its lower extremity above the rear outer part of the outer disc cutting zone and its upper extremity substantially above the forward part of said zone, the distance between the upper part of the outer disc and said edge increasing from the lower extremity to the upper extremity of said edge.

Abstract: The disclosure is of a haymaking machine for the tedding and/or windrowing of fodder, comprising especially a support beam extending transversely of the direction of travel of the machine and at least four rake wheels equipped with working tools which are driven in rotation so as to rotate in directions such that any two adjacent wheels rotate in opposite directions, especially with the purpose of forming two windrows in a single passage, characterized in that each of the central rake wheels is fixed to the extremity of a support arm the other extremity of which is connected to a pivot spindle situated on the transverse support beam, the said support arms being capable of being brought by pivoting about their pivot spindles into at least two positions, the one corresponding to a first working position of the machine in which the two extremities of the support arms are respectively situated on either side of the central plane of the machine, and the other corresponding to a second working position of the machi

Abstract: The disclosure is of a haymaking machine for the tedding and/or windrowing of fodder, comprising at least two rotors the axes of which form a certain angle with the ground, these rotors being interconnected by a hollow beam through which there passes a transmission shaft intended to drive the rotors with a rotating movement about their respective axes, said machine co-operating in the windrowing position with guide elements situated to the rear and fixed respectively each to one of the ends of arms extending towards the front of the machine, characterized in that the other end of at least one of the arms cooperates with means for modifying the angle of inclination of the rotors when the guide element of said arm is actuated.

Abstract: The disclosure is of a machine of mower or mower-conditioner type in which the working width is substantially equal to the total width and a drive element directly communicates its rotating movement to one of the discs mounted on an elongated housing which supports all the discs, of which that which co-operates with the drive element can advantageously be uncoupled therefrom.

Abstract: A haymaking machine for the tedding and windrowing of fodder, comprises a pair of rake wheels driven in rotation on which working tool carrier arms extend outwardly and are mounted for pivoting in support bearings articulatedly connected to a drive hub. Each of these arms has at its end adjacent the axis of rotation of the corresponding rake wheel, a control crank having a roller thereon. The roller rolls on one of two guide tracks. The inner guide track is for windrowing and the outer guide track is for tedding. The arms occupy a relatively raised position and the axes of rotation of the wheels are tipped forward during tedding; while the arms occupy a relatively lowered position and the axes of rotation of the wheels are substantially upright during windrowing.

Abstract: A haymaking machine for the tedding and windrowing of fodder comprises a pair of rake wheels driven in rotation, with working tool-carrier arms mounted pivotally in support bearings thereon and having at their ends facing the rotation axis of the corresponding rake wheel, a control crank that has a roller that moves in a guide cam so as to cause the working tools to pivot over a portion of their path of revolution, upward and in the direction opposite to the direction of rotation of the corresponding rake wheel during windrowing. The control cranks are connected with the working tool-carrier arms by means of an articulation, the angle formed between the geometric axes of the control cranks and the geometric axes of the working tool-carrier arms, as seen from above, varying when the carrier arms are transposed from the windrowing position into the tedding position and vice versa.
