A reversible lawn mower blade assembly includes a lawn mower that has an output shaft. A hub is removably coupled to the output shaft such that the output shaft rotates the hub when the lawn mower is turned on. The hub has a plurality of protrusions thereon radiating outwardly from a center of the hub. A plurality of blades is provided and each of the blades is removably coupled to a respective one of the protrusions such that the hub rotates the blades when the lawn mower is turned on. Each of the blades has a first cutting edge and a second cutting edge. Moreover, each of the blades is reversible on the hub such that a selected one of the first or second cutting edges faces the direction of the hub's rotation thereby enhancing a service life of the blades with respect to cutting.
