Abstract

The invention refers to an agricultural machine comprising at least one seed metering device (8) for distributing seeds to the soil (9) over which the agricultural machine (1) moves, which seed metering device (8) comprises a seed metering element (803) at which a case (802) is arranged, which case (802) communicates with an air pressure device (501, 502) by means of which a pressure difference between a first and a second side (821a, 822a) of the seed metering element (803) can be provided, in addition to which the seed metering element (803) is by means of a drive device (401 ) rotatable around a seed metering axle (805) and provided with a plurality of through retaining recesses (804) disposed at a distance from the seed metering axle (805) for uptake, by means of the pressure difference, of seeds (91), A control entity (451 ) that is adapted through controlling of the air pressure device (501, 502) to control the pressure difference at least partly in dependence on the speed of the agricultural machine.
