摘要：
A drive assembly driven by a drive unit locks one or several operating units (6) of an agricultural implement (1) or of a self-propelled implement. The operating unit (6) can be locked when switching off the drive unit or upon reaction of an overload coupling (4). The drive assembly (3) has an overload coupling (4) connected to the drive unit and driven by the drive unit in one driving direction of rotation. The overload coupling (4) is also connected to the operating unit (6). The drive assembly (3) further has a brake unit (5) connected to the overload coupling (4). The brake unit (5) is intended to be arranged in the driveline between the overload coupling (4) and the operating unit (6). Actuating mechanism (10) actuates the brake unit (5) when the operating unit is running so that the operating unit is braked and locked. Thereafter, the overload coupling is disconnected.
