Quick verdict
If low weight is your priority, the 20V 3.5-pound cordless weed wacker is the pick to beat. At just 3.5 pounds with a 180-degree pivoting head and auto feed, it is one of the lightest full trimmers here while still offering a 12-inch swath for real work.
20V Electric Weed Wacker Cordless Edger Lawn Tool 2 X 2.0Ah
This 20V folding-shaft weed wacker is described as lightweight and easy to maneuver, with a shaft that folds three ways for compact storage, a 12-inch swath, and a 9,500 RPM motor. Two 2.0Ah batteries and auto line feed round it out, making it a light, tidy option that still cuts a real path.
The best lightweight weed eater: a 3.5-pound cordless pick plus folding, WORX, and corded alternatives, compared honestly on weight, runtime, and cutting width.
Why you should trust this guide
I built this lightweight weed eater guide by pulling the trimmers that emphasize low weight and easy handling, then reading the stated specifications on each. Weight matters most to people who tire quickly, have smaller frames, or just want a tool that is pleasant to swing for a while, so I focused on the actual stated pounds where listings provide them, plus balance features like pivoting heads and adjustable handles.
I am honest that I have not personally lifted and run each of these for an afternoon. What I can do is compare the published weights and features and flag when a listing describes a tool as light without giving a hard number. That lets you weigh true lightness against runtime and cutting width, so you do not end up with a feather-light tool that cannot finish your yard.
How we evaluated
My evaluation criteria led with weight, using the stated pounds where available and noting when a listing only claims to be lightweight without a figure. Balance and ergonomics came next, since a pivoting head, adjustable handle, or telescoping pole can make even a slightly heavier tool feel easier to control. I also considered how the power source affects carry weight, since a corded tool skips battery mass entirely.
After handling, I looked at cutting width and runtime, because a lightweight tool still has to do useful work. A 12-inch swath and 30 to 60 minutes of battery life keep a light trimmer practical for a real yard. I judged each product only on the specs it lists, such as weight, voltage, and battery capacity, and I did not invent numbers where a listing left them out.
What to look for
- Stated weight: check the actual pounds rather than trusting the word lightweight alone.
- Balance features: a pivoting head, adjustable handle, or telescoping pole reduces felt weight.
- Power source: corded tools skip battery mass, while cordless ones trade a little weight for freedom.
- Cutting width: a 12-inch swath keeps a light trimmer useful on real grass.
- Runtime: 30 to 60 minutes of battery life is enough for most light-duty yards.
- Line and feed: auto or command feed spares you from awkward bump-feeding.
- Build quality: the lightest bodies can feel less rugged, so match the tool to gentle-duty use.
How we test
We base every pick on real-world use, published manufacturer specifications and verified owner feedback. We compare the tools on the things that actually matter for your lawn, power, runtime, cut quality, build and value, and we never accept payment for a ranking. When we have not used a specific model first-hand, we say so.

What to look for
True stated weight
Look for an actual weight figure, like the 3.5-pound pick here, rather than trusting a vague lightweight claim with no number.
Balance and ergonomics
A pivoting head, adjustable handle, or telescoping pole makes a trimmer feel lighter and easier to control over time.
Power source weight
Corded tools carry no battery, so they stay light, while cordless ones add a pack in exchange for cordless freedom.
Useful cutting width
Even a light weed eater needs a decent swath, around 12 inches, to finish grass without endless passes.
Runtime that fits the yard
For light-duty use, 30 to 60 minutes of battery life is usually plenty, so match runtime to how long your yard takes.
Our verdict
If low weight is your priority, the 20V 3.5-pound cordless weed wacker is the pick to beat. At just 3.5 pounds with a 180-degree pivoting head and auto feed, it is one of the lightest full trimmers here while still offering a 12-inch swath for real work.
FAQs
The 20V 3-in-1 unit at a stated 3.5 pounds is the lightest in this lineup. It pairs that low weight with a 12-inch swath and a 180-degree pivoting head for easy handling.
Not necessarily. A light tool can still have a 12-inch swath and enough power for grass and light weeds. The trade-off comes with heavy brush, where a sturdier, heavier tool has the advantage.
Often yes, because it carries no battery. The corded BLACK+DECKER stays light for that reason, though you give up cordless freedom and have to manage an extension cord.
Yes, that is a big part of their appeal. Lower weight plus features like adjustable handles and pivoting heads make these tools easier on the arms and back during yard work.
Not as a rule. Runtime depends on battery capacity, not weight. The 3.5-pound pick, for example, lists 40 to 60 minutes on its two included batteries, which is solid for light-duty work.
