Self-propelled forage harvester and methods of harvesting using a forage harvester

摘要

The present application relates to a forage harvester (1), comprising a drive device (2) which has a drive shaft (3), a processing device (4) which has two conditioning rollers (5, 6) and a transmission device (7) which has a Has belt drive, the conditioner rollers (5) each comprising an output shaft (8, 9) and are arranged parallel to one another so that they jointly delimit a working gap (10), the belt drive at least one drive belt (11) and at least one of the drive shafts (3 ) has associated drive belt pulley (12) and at least one driven belt pulley (13, 14) associated with at least one of the driven shafts (8, 9), the drive shaft (3) by means of the drive belt (11) in a force-transmitting manner with the driven belt pulley (13, 14) ). In order to provide a forage harvester whose transmission device is constructed more simply than in the prior art, the invention provides This means that the transmission device (7) comprises at least two switching stages, by means of which a speed ratio between the output shafts (8, 9) of the conditioner rollers (5, 6) can be changed, the transmission device (6) from a driver's cab (15) of the forage harvester ( 1) can be switched off.
