A clutch brake arrangement for farm work machinery or other equipment comprises a rotary member rotatably attached to an output shaft extending through a cam plate mounted on an engine mounting. A pressure plate is mounted on the cam plate in such a manner that it is movable along said output shaft. A brake spring is provided to bias the pressure plate toward the rotary member. A lining plate is disposed between the rotary member and a clutch disc rotatable with the output shaft. A clutch spring is provided to bias the lining plate toward the clutch disc to engage it with the pressure plate. The pressure plate is moved toward the cam plate against the brake spring, so that the lining plate is engaged with the clutch disc and, thereafter, is spaced away from the pressure plate. A plurality of projections are discontinuously formed on the peripheral portion of the pressure plate which is outside of its braking plane.
