Abstract: A distributor (10) of dry, particulate material released in metered amounts by a hopper (22), for the treatment of forage in a mechanical baler (12). A manifold (30) has an air inlet (34) and at least one air outlet (32). An air blower (38) is adapted to discharge into the air inlet (34) at a selected flow rate. A bender (40) has an air tube (48) communicating with the air outlet (32) and a particulate material discharge tube (50) adapted to receive particulate material from the hopper (22). The particulate material discharge tube (50) discharges within the air tube (48), suspending the particulate material in the air. A distributor nozzle (52) communicates with the blender (40) and has a focusing vent (54) and an impact plate (56) facing the focusing vent (54) to receive and deflect particulate material exhausted therethrough.
