A manual reel mower can be a great option for anyone who has a very small yard and not a lot of storage space. Their compact designs are perfect for tiny garages and tool sheds, and since they don't need gas or batteries, you don't have to worry about keeping extra fuel or chargers on-hand to do your yard work. They're also a more eco-friendly option, even compared to battery-powered push mowers, since they're human-powered; no nasty exhaust to breathe in, oil spills to clean up, or increased carbon footprint from charging batteries. They do have some drawbacks, though. You have to mow frequently, since the barrel blades can bind when used on taller grass. And since they're made almost entirely of steel, they can be quite heavy and more difficult to maneuver.
