QUICK ATTACHABLE AND DETACHABLE MOWER BLADE ASSEMBLY Abstract of the Disclosure A quick attachable and detachable mower blade assembly comprising a blade member and blade holder member having flat adjoining surfaces and fixed to the lower end of a vertical drive shaft. A pair of studs are fixed to and project from one of the members through stud openings in the other of the members. The latter openings have an enlarged portion for passing the head of the studs and a narrow portion extending from the enlarged portion to an end conforming to the shape and dimension of the shank of the respective stud. The narrow portions of the openings are located and directed so that the studs, when seated in the respective ends, prevent axial and angular movement between the blade member and the blade holder member. The blade holder member and blade member have, in addition, a central opening which receives a downwardly biased pin extending from the lower end of the drive shaft. The pin will automatically sit in this latter opening upon the blade and holder members being positioned so that the studs are seated in the ends of their respective openings.
