A clutch-brake assembly (10) for a mower includes a housing (12), a shaft (20) rotatably connected to a prime mover, a clutch plate (30) operatively received onto the shaft, a brake ring (41) and a pulley (50) of which the pulley is selectively engageable with the clutch pad or brake ring. An actuator, that may be a vacuum actuator, applies equal and opposite forces to disengage the brake ring and engage the clutch plate, which in affect allows for the transmission of rotational power from the shaft to the pulley.
