Abstract: A mower including a hitching structure configured to be connected to a motor vehicle, a cutting mechanism, a maneuvering device configured to bring the cutting mechanism from a working position to a maneuvering position, and a lightening device configured to transfer a part of the weight of the cutting mechanism onto the hitching structure, the lightening device including a hydraulic cylinder.

Abstract: A mower including a hitching structure configured to be connected to a motor vehicle, a cutting mechanism, a maneuvering device configured to bring the cutting mechanism from a working position to a maneuvering position, and a lightening device configured to transfer a part of the weight of the cutting mechanism onto the hitching structure, the lightening device including a hydraulic cylinder.

Abstract: An operating device for an agricultural machine which includes a hitching structure connected to a motor vehicle by use of an upper hitching point and at least one lower hitching point. A second lower hitching point is connected to the device and the hitching structure is movable with respect to the second lower hitching point by use of the device. The device thus makes it possible to bring the agricultural machine from a work position into another position or vice versa.

Abstract: A mower comprising a cutting mechanism which, during work, extends transversely to a direction of work, a hitching structure connected to a motor vehicle, a carrying beam connected, on one hand, to the cutting mechanism by a first articulation and, on another hand, to the hitching structure by a second articulation and of a third articulation, which allows the second articulation to pivot with respect to the hitching structure, a device, for moving the carrying beam and the cutting mechanism between at least one transport position and one other position, and vice versa, and a lifting member for moving the carrying beam and the cutting mechanism between a work position and a maneuvering position, wherein the lifting member is associated with a damping member for absorbing abrupt movements of the carrying beam with respect to the hitching structure when the carrying beam is in the maneuvering position or respectively in the transport position.

Abstract: A machine for cutting plant matter equipped with a limiter device includes a first assembly connected to a first unit and a second assembly connected to a second unit. The second unit is connected to the first unit by an articulation allowing the second unit to pivot about an axis of the articulation within limits allowed by at least one stop. The stop is elastically deformable so as to limit pivoting of the second unit about the axis when the second unit is subjected to a first pivoting torque, and so as to tolerate a much greater amount of pivoting of the second unit about the axis when the second unit is subjected to a second pivoting torque.

Abstract: The invention includes a stop (33) which prevents movement of the part (23) of the protection device (18) into the non-operating position when the cutting mechanism (2) is located in the work position (A), and which allows movement when the cutting mechanism (2) is located in a different position (B), the activation of the stop (33) being accomplished automatically by means of an activation element (35) when the cutting mechanism (2) is brought from the other position (B) into the work position (A). The invention also includes a limiting element (52) for limiting the amount of pivoting between a support arm (5) and the cutting mechanism (2) in work position (A) and preventing pivoting when the cutting mechanism (2) is in the other position (B).

Abstract: A mower includes a cutting mechanism, an attachment structure, a carrying beam connected to the cutting mechanism by way of a first articulation and to the attachment structure by way of a second articulation and a third articulation, and a safety device including an energy accumulator. The safety device includes a pivoting member connected to the attachment structure by way of a fourth articulation and a connecting rod installed between the pivoting member and the cutting mechanism or the carrying beam. The energy accumulator is connected to the pivoting member by way of a connection which is capable, from a certain angle of pivoting of the cutting mechanism toward the rear, about the axis of the third articulation, of reducing the lever arm with which the energy accumulator acts on the pivoting member.

Abstract: A mower includes a first chassis attachable to a tractor for movement in a work direction, a second chassis having first and second structures connected at a joint extending perpendicular to the work direction, and connecting rods, each having respective ends pivotally connected to the first chassis and to the second structure of the second chassis so as to form with the first and second chassis an upwardly deformable quadrilateral deformable such that the work elements may move to adapt to ground contours. A release safety device normally prevents pivoting of the first structure about the joint but permits pivoting of the first structure about the joint axis when the first structure or the working elements hooks an obstacle during movement of the mower in the work direction. This limits forces applied to the mower.
