A blade is selectively attachable to the mounting plate. The blade defines a retaining plate aperture and a third pin aperture. A biasing member urges the movable pin plate from a disengaged position to an engaged position. The pin is engageable with the pin apertures for mounting and retaining the cutting blade to the mounting plate. The blade is attached by moving the blade over the retaining plate aperture, urging the movable pin plate to the disengaged position, rotating the blade, and releasing the movable pin plate.
