Title: Rotary power mower with improved clutch and brake mechanism

Abstract: A rotary power mower in which the cutter blade is fixed to the bottom of a cup-shaped rotor, freely rotatably suspended from a carriage that is slidably mounted for fore and aft movement beneath the deck of the mower chassis. The carriage is spring-urged to a position in which the outer face of the side wall of the cup-shaped rotor is frictionally engaged with a brake shoe fixedly carried by the mower chassis, to hold the cutter blade against turning; and a deadman control mounted on the handle of the mower and operatively connected with the carriage enables the operator to move the carriage against the force of the spring to a position in which the inner face of the side wall of the cup-shaped rotor is tangent to and frictionally engaged with the periphery of a drive wheel fixed to the engine drive shaft.
