A transmission arrangement has a transmission housing, an output shaft for driving an implement, a drive component for driving the output shaft, a clutch arranged between the output shaft and the drive component for transmitting a torque, a brake device for braking or locking the output shaft in relation to the transmission housing, an annular piston which is supported so that it is axially displaceable on the output shaft and which in a first position serves to actuate the clutch and in a second position actuates the brake device, and a freewheel device, which allows the output shaft to be rotated over a limited part of its circumference whilst in a locked state.
