Abstract:
A spreading machine, in particular a precision seed drill, includes at least one seed hopper, at least one fertilizer tank, and a several spreading units. Each of the spreading units includes at least one pneumatically operated separating device, to or from which a separation air flow is suppliable or dischargeable, and a fertilizer application device. The spreading machine includes a conveying air-driven seed feeding device for providing seed from the seed hopper to the spreading units, and an energy-powered fertilizer supply device for providing fertilizer to the fertilizer application devices. To refine a spreading machine that includes a plurality of consumers, the spreading machine includes at least two separate energy suppliers, in particular blowers or pumps, for providing the separation air flows to the separating devices, the conveying air to the seed feeding device, and the energy to the fertilizer supply device.
