Abstract: An agricultural machine includes a processing unit equipped with an endless belt conveyor and being able to take up a work position in which the conveyor makes it possible to move a product, the movement of the belt being guided by at least two rollers guided in rotation about longitudinal axes; a tensioning system associated with the belt and including an energy accumulator and a tensioning cylinder making it possible to make the distance between the longitudinal axes vary; a regulating system associated with the belt, which prevents, in the work position of the processing unit, oil from flowing from a first pipe connecting the regulating system to a hydraulic control valve, to a second pipe connecting the regulating system to the tensioning cylinder, when the pressure in the second pipe is greater than a maximum value.

Abstract: The present invention relates to an agricultural haymaking machine comprising a chassis resting on the ground by at least one wheel and intended to be coupled to a tractor able to move the machine in a direction of advance, a carrier carrying a plurality of rotors being swivel mounted to the chassis around a central pin oriented transversally to the direction of advance, each rotor being driven around a respective drive axis, and a lift actuator, articulated to the chassis on one hand and to the carrier on another hand, being able to make the carrier pivot around the central pin relative to the chassis, the machine being able to adopt a headland configuration in which the carrier is raised, as well as a work configuration in which the carrier rests on the ground by means of at least one support. The central pin is rigidly attached to the carrier, and the machine comprises a positioning actuator able to move the central pin relative to the chassis to change the position of the drive axes relative to the ground.

Abstract: An agricultural machine includes: a work tool, a coupling frame including a crossing beam and two levers, each lever carrying a respective hitching point attached to a respective lower arm of the tractor and being able to move vertically relative to the crossing beam, each lever having an associated restoring device which can exert a force on the associated lever when the respective hitching point moves vertically relative to the crossing beam. The machine is able to occupy a work configuration in which the tool is close to the surface and a transport configuration, in which the tool is further away from the surface. Each restoring device includes a hydraulic restoring jack fixed to the respective lever on one side and to the crossing beam on another side, each restoring jack being hydraulically connected to a hydraulic tank in the work configuration.

Abstract: The present invention relates to the general technical field of agricultural machinery. It concerns an agricultural device, in particular a haymaking device, which can be moved in a direction of advance and which includes a cutter bar equipped with cutting elements intended to cut a standing crop product. The device also comprises a conditioner positioned behind the bar, and a grouping device intended to move the product transversely to the direction of advance and located behind the bar, in an active position. A retraction actuator is configured to transpose the grouping device between the active position and a passive position in which the product is deposited at the rear of the device. A collecting device extends partially under and partially behind the conditioner in active position of the grouping device. The invention also concerns an agricultural machine equipped with such a device and a method for access between a conditioner and a grouping device belonging to such a device.

Abstract: An agricultural facility arranged in a plot of farmland includes: a supply and/or maintenance station; an autonomous agricultural device performing an agricultural task in the plot of farmland; a control unit for moving the autonomous agricultural device and the station, which unit is configured to control movement of the autonomous agricultural device within the plot of farmland including a work area in which an agricultural task is performed by the autonomous agricultural device and an area to be worked in which an agricultural task is to be performed by the autonomous agricultural device. The control unit is configured to control movement of the station from the work area to the area to be worked if the autonomous agricultural device moves to perform an agricultural task in the area to be worked, movement of the station being independent from movement of the autonomous agricultural device.

Abstract: A seeder element of an agricultural machine includes a seed distribution element and a tamping device. The tamping device is arranged behind an outlet of the seed distribution element in a direction of advance at work of the seeder element. The tamping device includes an adjustment device and a tamping element. The tamping element exerts a tamping force on the ground in at least one work position of the adjustment device. The at least one work position of the adjustment device is a load-relieving position in which the adjustment device exerts, on the tamping element, a load-relieving stress that counters the weight of the tamping element.

Abstract: A method for working a plot of land simultaneously by at least two agricultural robots operating autonomously and independently, in accordance with instructions and/or commands transmitted by a common central management and control system, includes subdividing said plot of land to be treated into at least two distinct work zones and allocating each work zone exclusively to one of the agricultural robots. At least during the working phase, the width of the majority of the work zones is equal to a multiple, greater than or equal to 1, of the working width of the agricultural robot to which it is exclusively allocated. During work on a plot of land, work zones not yet worked are exclusively allocated to various agricultural robots, respectively, in a gradual manner according to the completion of the work undertaken by the agricultural robots in the various zones allocated to them.

Abstract: An agricultural machine is coupled to a tractor vehicle and includes a work unit connected to a chassis relative to which the work unit can be moved, the machine being able to take up a work configuration and a transport configuration. The machine includes a lightening device having a lightening cylinder connected to the chassis by a flexible compression tie-rod on one side and to the work unit at a front articulation on the other side, the lightening cylinder being able to transfer, in the work configuration, some of the weight of the work unit onto the chassis, the flexible compression tie-rod being attached with the lightening cylinder at an anchoring point and with the chassis at a fastening point, a deflection system making it possible to move the lightening cylinder by pivoting the anchoring point about the front articulation so as to move it away from the midplane.
