ABSTRACT:
A drive arrangement for an agricultural machine, especially a field chopper, has a motor driven gearbox (3) that is connectable at a drive-end to at least one drive motor (1). At least one first hydraulic pump (8, 8′) is provided to feed at least one hydraulic motor (14), (17) to drive a working mechanism of a machine. A belt pulley (4) of a belt drive (5), especially for driving a chopper drum (10), is coupled with the gearbox (3). A release clutch (7), with an input-side first clutch element (36) and an output-side second clutch element (37), is also coupled with the gearbox (3). The first clutch element (36) is drivingly connected to the motor driven gearbox (3). The second clutch element (37) is drivingly connected to the belt pulley (4). The second clutch element (37) is non-rotationally connected to a drive shaft (38) to drive the at least one first hydraulic pump (8, 8′).
