Abstract

A large round baler is provided with a crop take-up arrangement as well as a knife shaft ahead of the inlet of a baling chamber which carries knives that cooperate with blades of a first rotor to cut crop material into pieces before the first rotor delivers the crop directly into the baling chamber. A second rotor is provided between the take-up rotor and the first rotor shaft for narrowing the crop flow from that of the crop take-up arrangement to that of the first rotor. All of the rotors perform an overshot conveying that requires a relatively low drive energy and guarantees a continuous flow of the crop into the chamber.
