Distribution nozzle (14) for an agricultural machine (10), which nozzle is placed adjacent to a rear edge (26) of a loosening share (18). The distribution nozzle (14) is provided with at least two outlets (31, 32), the distribution nozzle (14) being provided with a distributor device (27) that distributes the amount of bulk-type material to said outlet (31, 32). The distributor device (27) comprises at least one reflector (30) placed in the distribution nozzle (14). The inner edge (41) of the reflector works to divide the streaming bulk material so that one portion (31) passes past the inner edge (41) and one portion (32) is deflected by the edge (41) and distributed along the reflector (30). Said reflector (30) is detachably and adjustably mounted in the distribution nozzle (14). The invention also concerns an agricultural machine comprising at least one such distribution nozzle (14).
