Abstract

A drive assembly for an operating unit (9) of an agricultural implement or an agricultural machine has a clutch (4) with an input (34). The input (34) is mechanically and drivingly connected to a drive engine (1). A summarizing gear unit (8) has a first input (20), a second input (24) and an output (26). The first input (20) is mechanically and drivingly connected to an output (35) of the clutch (4). The output (26) acts to drive the operating unit (9). A hydraulic pump (10) is mechanically and drivingly connected to the output (35) of the clutch (4). A hydraulic motor (11) is hydraulically connected to the hydraulic pump (10). The motor (11) is mechanically and drivingly connected to the second input (24) of the summarizing gear unit (8).
