ABSTRACT OF THE DISCLOSURE A clutch brake arrangement for farm working machinery includes a boss parallel with an output shaft extending from an engine mount, a rotary member rotatably mounted on the output shaft, and a pressure plate mounted on the boss in such a manner that it is slidable along the axial direction of the output shaft. The plate is provided for pressing a lining plate rotatable with the rotary member. A brake spring is resiliently disposed between the engine mount and the pressure plate. A cam plate is provided on the boss and cam balls are arranged between the pressure plate and the cam plate. A retaining ring holds the cam plate on the boss. In this way, these parts can be arranged near the engine mount, whereby the length, as viewed in the axial direction of the output shaft, and hence size of the arrangement can be decreased. Furthermore, since the movement of the operating mechanisms along the axial direction of the output shaft is slidably guided by the boss, the parallel movement thereof is made so smooth and reliable that clutch engagement and disengagement can effectively be carried out. In one embodiment a dust cover for covering the arrangement is attached directly to the engine mount. Between the duct cover and the pressure plate is resiliently disposed a brake spring, by which the dust cover is engaged with, and held on, the engine mount.
