Abstract: Embodiments of the present disclosure are directed to lawn mowers (e.g., walk power mowers), having a deck supported for travel over a ground surface. The deck may support a prime mover having an output shaft adapted to power a cutting blade contained within a cutting chamber defined by the deck. The mower may also include a drive system to power the cutting blade. In some embodiments, the cutting blade may attach to the output shaft of the prime mover via a friction interface such that, upon unintended blade contact with obstacles, the blade may rotationally slip relative to the output shaft. Moreover, the mower may include a blade brake clutch (BBC) adapted to permit selective activation and deactivation of the blade independent of the prime mover.
