According to the invention, the connecting device comprises an insert with at least one tapping able to be inserted inside the engaging portion, the threaded element is screwed in the tapping and the shoulder rests on the engaged portion to tighten the engaged portion against the engaging portion.

Abstract: A single seeder with a foldable chassis composed of a central section arranged transversely with respect to the direction of work and of two lateral sections articulated on the central section, seeder elements being distributed in a regular manner on the chassis, the seeder including burying coulters for the distribution of product extending at the front of a respective seeder element, a distribution head and pipes connected on the distribution head and ending at the burying coulters. The distribution head is arranged at the rear of the seeder, behind the seeder elements, taking into account the direction of advance.

Abstract: A harvesting machine includes a frame carrying at least one harvesting mechanism and a lightening device of the harvesting mechanism. The lightening device includes second hydraulic jacks articulated on the frame and on the harvesting mechanism and connected by hydraulic circuits to first hydraulic jacks so as to be able to be actuated by the first hydraulic jacks and to hydropneumatic accumulators.

Abstract: A mower-conditioner including a plant mowing mechanism including a cutting device, a plant conditioning system and a mechanism lifting these elements relative to the ground, this assembly being carried by a frame and including a fairing, the machine also including a plant ejection channel positioned as an extension of the plant conditioning system. The fairing is articulated to the plant ejection channel by a transverse axis that is positioned inside the machine, above and slightly behind the plant conditioning system, and the plant ejection channel is itself articulated to the frame.

Abstract: The present invention relates to an agricultural haymaking machine intended to be hitched to the lower arms of a tractor, comprising a frame supported on the ground by wheels and at least one work device connected to the frame, the frame being in its front part in pivoting connection with a hitching device configured to be connected to the two lower arms, the center of gravity of the machine being situated between the wheels and the hitching device. According to the invention, the projection of the axis of the pivoting connection, on a plane which is substantially vertical and substantially parallel to the direction of advance, has an inclination towards the direction of advance following a direction of the ground upward.

Abstract: An agricultural machine including a carrying vehicle and plural work units configured to cut a standing product. The agricultural machine includes at least two pivotable front work units arranged, during work and viewed in a direction of forward travel of the carrying vehicle, at a front of the carrying vehicle, and at least two lateral work units arranged, during work, on either side of a work area of the front work units. The front work units and the lateral work units can be moved with respect to the carrying vehicle and can pivot in mutually opposite directions with respect to each other, to occupy a transport position or a work position. In the work position, a work area of a first front work unit partially overlaps a work area of a second front work unit. At least one of the front work units is connected to a height adjustable front hitching device of the carrying vehicle.

Abstract: An agricultural machine including a carrying vehicle and plural work units configured to cut a standing product. The agricultural machine includes four steering and driving wheels that support the carrying vehicle, at least two front work units arranged, during work and viewed in a direction of forward travel of the carrying vehicle, at the front of the carrying vehicle, and at least two lateral work units arranged, during work, on either side of a work area of the front work units. The front work units and the lateral work units can be moved with respect to the carrying vehicle and can pivot in mutually opposite directions with respect to each other, to occupy a transport position or a work position. In the work position, a work area of a first front work unit partially overlaps a work area of a second front work unit.
