Harvester

摘要

The harvester has a conditioner unit (4) that comprises two co-operating roller-shaped conditioner rotors (5, 6) for conditioning of crops. The rotors are driven by a drive device (7) with regard to each other. The drive device comprises a belt drive (8). A belt (9) i.e. double-sided interlocked toothed belt, is utilized for coupling one of the conditioner rotors with a two-belt pulley (11). The conditioner rotor is coupled via another belt (10) that is utilized for driving another conditioner rotor. The rotors together with the pulley are movably support at a main rotor shaft (12).
