Lawn mower blades and hammers are cutting elements used to cut grass, weeds, branches and other vegetation. Lawn mower blades and hammers are mounted on the rotor of a flail mower or mulcher, which rotates at high speed and cuts vegetation. Lawn mower blades and hammers can come in various shapes, sizes and weights, depending on the type of mower and its intended use. Lawn mower blades and hammers are made of high-quality steel, which makes them durable and resistant to wear. Lawn mower blades and hammers should be sharpened and replaced regularly to ensure optimum cutting quality.
