the present invention relates to an agricultural machine with a gutaufnehmer (1) for recording of crop from the ground and a f u00f6rderrotor (3) for the crop material through the channel of the weiterf u00f6rdern (4) through the channel (4) and a movable gelag equipment f u00f6rderkanalwand (5) is limited.so that by moving the f u00f6rderkanalwand (5) of the f u00f6rderkanalquerschnitt changes. it is proposed that the f u00f6rderkanalwand (5) such that the movable hanging, f u00f6rderkanalquerschnitt along the f u00f6rderrichtung uniformly increases or younger, if the f u00f6rderkanalwand of f u00f6rderrotor (3). in these animals.
