A lawn mower blade assembly for a rotatable driveshaft includes a blade mount to be secured to the rotatable driveshaft and having at least one wedge surface thereon. A cutting blade is removably coupled to the blade mount. At least one sliding retainer removably couples the cutting blade to the blade mount and is slidably movable between a locked position and a released position. The at least one sliding retainer has at least one wedge surface thereon cooperating with the at least one wedge surface of the blade mount to securely couple the cutting blade to the blade mount when in the locked position.
