Abstract: A combine harvester with a rotor housing which is positioned in a lengthwise direction and with an inclined angle towards the horizontal line inside of the combine. To arrange the rotor housing in a favorable way inside of the combine harvester, it is suggested to use a feeder house which comprises elements which distribute harvested material from the cutterbar in an up and rearward direction towards its discharge end, said discharge end being arranged in a height substantially above of the rotational axis of the front wheels and in a region before the rotational axis of the front wheels, the discharge end feeds the harvested material into the feeding opening of the rotor housing of the separation unit being arranged in the upper half of it, whereby the rotor housing reaches with its front from a region before the rotational axis of the front wheels and a lower third of the height of the combine harvester to its rear being arranged in the top rear half portion of the combine harvester.
