ABSTRACT:
An assembly for effecting driving or braking of a rotatable working element hich tube may be operatively connected to the powered rotary shaft, and passes through a central bore in the adaptor plate and has a collar that is dimensioned so that it cannot pass through the central bore. A spring biases the adaptor plate and drive plate apart. When the adaptor plate is connected to a working element, such as a rotary lawn mower blade, and the adaptor tube and drive plate are connected to the rotary shaft, by moving the adaptor plate with respect to the drive plate and a stationary housing portion in a direction parallel to the rotary shaft, braking or clutching is provided by engagement of a friction ring with the housing portion or drive plate, respectively. The adaptor tube, actuation plate, adaptor plate, and drive plate comprise a subassembly for ease of construction and mounting.
