A mechanical overload protection unit e.g. slip clutch or disengaging clutch, is arranged between the transmission and the pinion. The overload protection unit is designed as a predetermined breaking point (20) of an output shaft. A common housing (10) i.e. oil-tight housing, is provided for the transmission, the overload protection unit and a main bearing (9) of the output shaft. The predetermined breaking point is realized by shear pins.
