1. A spreading machine for precision seed drilling, the spreading machine comprising:
a seed hopper;
a fertilizer tank;
a plurality of spreading units, each of the plurality of spreading units comprising:
a pneumatically operated separating device operating with positive pressure, a separation air flow being supplied to or discharged from the pneumatically operated separating device, and
a fertilizer application device;
a conveying air-driven seed feeding device for providing seed from the seed hopper to the plurality of spreading units, wherein the separation air flow and a conveying air flow of the conveying air-driven seed feeding device are combinable in the respective pneumatically operated separating devices;
an energy-powered fertilizer supply device for providing fertilizer to the fertilizer application devices;
a plurality of separate energy suppliers for providing the separation air flow to the pneumatically operated separating devices, the conveying air to the conveying air-driven seed feeding device and energy to the energy-powered fertilizer supply device;
a seed delivery channel for a delivery of the seed, wherein the seed is separated in the seed delivery channel; and
a catcher roller arranged within a delivery area of the seed delivery channel and configured such that the seed is run over by the catcher roller to decelerate the seed.
