CHOPPING MODULE CHOPPING MODULE, developed with means to catch and pull the plants by pushing them between a rotating cutting set and chopping them into billets, which comprises a case-shaped body (1) with three open sides, a front inlet (2) for plants to be chopped, a rear outlet (3) for chopped plants and a lower outlet (4) for residues plants are pulled by two crosswise pairs of rotating pulling rollers for the plants to be chopped (5a) and (5b), after which the set of fixed shearbar (6) is assembled crosswise, which upper side is aligned to the diameters of the lower stationary pulling rollers (5a), wherein, between those and the upper floating pulling rollers (5b), it forms a passageway (7) for the plants to be chopped and, after the fixed shearbar (6), said passageway continues in the form of a slide (8) sloping downwards to the outlet (3) for chopped plants and also a crosswise rotating cut device (9), located above the slide (7) and next to the fixed shearbar (6).
