An agricultural machine, includes a frame with a pair of wheels enabling movement in one direction, at least two harvesting devices for agricultural products connected to the frame that, in a work position, are arranged frontally to the wheels and aligned with each other transversely to the one direction. Unloading equipment is arranged operationally downstream of the harvesting devices to receive the harvested agricultural products and to move them in an unloading direction transverse to the one direction. The unloading equipment includes a central unloading device that is movable with respect to the harvesting devices between a work position, wherein it directly receives the harvested agricultural products from the harvesting devices, and a non-operational position, wherein it is offset with respect to the work position so as to enable the harvested agricultural products to fall immediately downstream of the first harvesting device.

A plant lifting device is mounted on an agricultural machine and includes a drum that is articulated to a frame around a first substantially horizontal axis and which includes a substantially cylindrical casing that has openings through which seizing means intended to lift plants situated outside the casing are able to protrude. A rotor is provided onto which the seizing means are fastened and that is able to be driven in rotation relative to the frame around a second axis directed substantially parallel to the first axis and separate from it, in which, when the device is operated, the second axis is fixed relative to the first axis. A rotational movement transmission means includes at least one rod articulated to the drum on one hand and to the rotor on another hand.

A swath lifter includes a rotor over which the crop is carried with the rotor driven in a direction so that an underside of the rotor adjacent the ground is driven opposite to the direction of movement. The rotor carries rows of tines at angularly spaced positions around the rotor each associated with a flexible strip of a resilient material located in front of the tines and covering an inner part of the tines with the outer part exposed. The rotor can be arranged with its axis inclined to a line at right angles to the forward direction thus tending to carry the crop to one side to direct the cop onto an adjustable swath guide board to cooperate to form the swath into a desired condition. The rotor can be used as a front member in a pickup for example for a baler.

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.
