ABSTRACT:
A pneumatic distributing device which can be used for broadcasting particulate fertilizer, herbicide or the like includes a tank, a slot across the tank with a metering roller in the slot for metering the particulate material into a number of receptacles arranged along the slot. A first venturi at the bottom of the receptacle transports the material in the receptacle through a first portion of the duct to a junction provided by a second venturi and a second duct. The second duct extends outwardly along a boom with a number of such ducts arranged in a vertically stacked arrangement which is selfsupporting. The second ducts incline slightly downwardly and are straight from the feed end to an open mouth at the outer end. A deflector attached to the open mouth has a first and then a second surface for spreading and then deflecting the material from the open mouth to the ground with the spread taking place along the length of the boom.
