The benefits of manual reel lawn mowers include quiet operation, no fuel, no pollution, low cost and maintenance, and ease of use. Reel lawn mowers are often much lighter and smaller than gas-powered lawn mowers, so they are easier to maneuver and take up less space in the garage.
Because manual lawn mowers have no motor, they don't require fuel or replacement parts like spark plugs and filters. The only noise the machine creates is the quiet cutting of the grass, so the machine won't disturb neighbors. Reel lawn mowers don't require much maintenance. They also don't produce the same kind of pollution as gas models. Manual mowers are generally cheaper to buy, saving money up front and in the long run.
