Abstract: A connection arrangement between a feed roller and a gearbox of a field chopper has a first shaft (25) with a central bore (26) that is rotatingly supported around an axis of rotation D, in a gearbox housing (30). A second shaft (32) is connected to a feed roller. The second shaft (32) is rotatingly supported around the axis of rotation D. The second shaft (32) has a central bore (33) that is aligned with the central bore (26) of the first shaft (25). A connecting journal (37) rests in the central bore (26) of one of the two shafts (25). The connecting journal (37) is form-fittingly connected to the central bore for torque transmission. It is axially displaceable along the axis of rotation D between a connected position where it is inserted into the central bore (33) of the other of the two shafts (32), and a released position, where it is pulled out of the central bore (33) of the other of the two shafts (32).

Abstract: An agricultural machine, especially a field chopper, has a carrier vehicle (28) with an intake unit (18) mounted on and arranged to the carrier vehicle (28). The intake unit has an intake gearbox (19) and at least one feed roller (21, 21?; 24, 24?) to guide the harvested goods to a chopper drum (10). The intake gearbox (19) is drivingly connected to that at least one feed roller (21, 21?; 24, 24?). The intake unit (18) is at least partially detachably attached to the carrier vehicle (28). A hydraulic motor (17) is mounted on and arranged to the carrier vehicle (28). The hydraulic motor (17) drives the intake gearbox (19). The hydraulic motor (17) has a drive shaft (40) that is detachably and drivingly connected to an input shaft of the intake gearbox (19).
