A centrifugal clutch brake for farm work machinery or other apparatus is provided comprising a member attached rotatably to an output shaft extending from a member fixed to an engine mounting, a clutch plate disposed between a drum rotatably together with said output shaft and the fixed member, a disc plate mounted on the clutch plate in face-to-face relation to the fixed member, a brake plate disposed between the disc plate and the clutch plate toward the fixed plate, a clutch spring provided for biasing the clutch plate toward the drum, and a fly-weight mounted on the clutch plate. The fly-weight is adapted to be expanded by a centrifugal force until it is placed in engagement with the drum. With such an arrangement, when a push is given to the brake plate against the pressure spring, the disc plate is spaced away from the fixed member with subsequent disengagement of the brake plate out of the disc plate, thereby urging the fly-weight upon the drum .
