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.
