Abstract: The present invention provides a lawn mower for cutting grass and maintaining the lawn surface. The lawn mower has a mower deck, a cutting blade driven by a motor, and a blade changing mechanism. The blade changing mechanism includes a fastener for securing the cutting blade to the motor, a blade securement tool for limiting the cutting blade from rotating, and at least one opening on the mower deck for removably receiving the blade securement tool. An edge guide is also provided on the mower deck. The lawn mower also includes a dynamic power management system configured to adjust a rotation speed of the motor dynamically based on a duty condition of the cutting blade.
