A pneumatic distribution system for an agricultural machine includes an air source having an outlet, an assembly configured to receive agricultural material from a material source, and a plurality of conduits. Each conduit is configured to receive an air stream from the outlet for conveying a portion of the agricultural material to at least one device associated with the agricultural machine. A first one of conduits corresponds to a first distribution line and is positioned such that the first conduit receives a first air stream from a first area of the outlet, a second one of the conduits corresponds to a second distribution line and is positioned such that the second conduit receives a second air stream from a second area of the outlet having a lower air pressure than the first area, and the first distribution line has a higher pressure drop than the second distribution line.

A product distribution system includes a product on demand pick-up assembly including a hopper. The hopper is configured such that an air stream flowing into the pick-up assembly entrains product therein and conveys product downstream through a plurality of conduits. The product distribution system further includes a container for storing product prior to delivery of product to the pick-up assembly and a meter and conveyor assembly configured to move product from the container to the pick-up assembly hopper such that an amount of product greater than a predetermined quantity is maintained in the pick-up assembly hopper during operation of the system.

A powder-dispensing device in the form of a dense-phase powder pump or of a powder injector is provided to deliver coating powder from a powder reservoir to a powder-spraying device. To make the spray coating operation easier for the customer and to be able to make it more cost-effective, without having to compromise on good coating quality and good coating efficiency, a control device is integrated in the powder-dispensing device or is connected, in particular directly, to the powder-dispensing device and is designed to establish at least one parameter that is characteristic of a spray coating procedure carried out with the powder-coating device.

A pneumatic distribution system for pneumatically distributing material in an agricultural vehicle is described. In one example, the pneumatic distribution system comprises an air source having an outlet with different air pressures defining a pressure gradient across the outlet, and a plurality of inlet ports configured to receive air from the outlet for a plurality of distribution streams, comprising at least a first distribution stream with a first pressure loss value and a second distribution stream with a second pressure loss value that is greater than the first pressure loss value. The inlet ports for the first and second distribution streams are located relative to the pressure gradient such that the second distribution stream receives a higher air pressure than the first distribution stream.
