Abstract
A blade is secured to a blade adapter which is dimensioned to receive a fixed adapter. The fixed adapter is connected to the engine drive shaft of a rotary mower. The blade and fixed adapter are provided with cooperating surfaces which permit the adapters to be selectively locked together and separated from each other without requiring tools.
