摘要

agricultural machine (1) for harvesting a crop, which is equipped with a harvesting head (2) comprising: a cutter bar (10) for harvesting the crop; at least one transport system (20) adapted to transport the crop cut by the cutter bar (10) to a collection nozzle (2a) of the harvest head (2). The invention is characterized in that said at least one first transport system (10) comprises: a first transmission system (120) comprising a first flexible element (121) coupled to a pair of first rotatable elements (122) ; - a second transmission system (220) comprising a second flexible element (221) coupled to a pair of second rotary elements (222); at least one arm (21) coupled to said first flexible member (121) and said second flexible member (221) such that it extends substantially substantially transversely with respect to the cutterbar in the harvesting head (2) (10) during both the transport step (ft) and for transporting the crop cut by said cutter bar (10) and during a return step (fr).
