The best lightweight weed eater picks: ECHO eFORCE 56V, BLACK+DECKER 20V EASYFEED and a 5.5 lb WORX 3 in 1, plus tips on weight and balance.
Trimming along fences, flower beds and the base of trees is one of the most tiring parts of yard work, mostly because of the tool. A heavy gas trimmer vibrates, pulls on your shoulders and wears out your arms long before the edges are done, and it is a real obstacle for older gardeners and anyone with back or wrist problems. The best lightweight weed eater cuts cleanly, starts at the press of a button and stays comfortable for a whole session, so the last stretch of fence line looks as neat as the first.
We compared manufacturer specifications, the feedback of verified owners on Amazon, expert reviews and price against value to choose our picks. The three below cover different yards: an ECHO eFORCE 56V straight shaft trimmer with a battery and charger in the box, a BLACK+DECKER 20V MAX EASYFEED trimmer and edger for small yards, and a featherweight WORX 3 in 1 trimmer at just 5.5 pounds.
Our Top 3 Picks at a Glance
All three are battery powered, so there is no gas to mix and no pull cord. The difference is power, weight and price.
- Best Overall: ECHO eFORCE 56V DSRM 2100 Straight Shaft Battery String Trimmer (around $250). A 56V battery system and brushless motor from a brand known for professional grade equipment.
- Best Value: BLACK+DECKER 20V MAX EASYFEED String Trimmer and Edger LSTE523 (around $110). A 12 inch cutting width, two speed control and quick conversion to edging.

The product table above adds more light trimmers from EGO, Greenworks, Makita, WORX, SKIL, CRAFTSMAN and BLACK+DECKER.
How We Chose the Best Lightweight Weed Eater
We focused on the balance between weight and cutting power, because a trimmer that is light but cannot handle thick weeds is just as frustrating as a heavy one. We compared battery voltage, cutting width, line feed systems and edging features, then looked at owner feedback, favoring models that are well reviewed by a large base of buyers. Price was weighed against what comes in the box, and every pick is a current model in stock on amazon.com.
Lightweight Weed Eater Reviews
1. ECHO eFORCE 56V DSRM 2100 Straight Shaft Battery String Trimmer: Best Overall
- Power: ECHO eFORCE 56V battery platform
- Motor: brushless
- Cutting width: 16 inches
- Shaft: straight
- Kit: 56V battery and charger included
- Model: DSRM 2100
Why We Picked It
ECHO built its reputation on commercial grade gas equipment, and the eFORCE DSRM 2100 brings that pedigree to a battery trimmer that is light enough for homeowners to use all afternoon. It is our top pick for large yards on a light battery trimmer, because it pairs the reach of a full 16 inch cutting path with the low weight and simplicity of cordless power.
The 56V eFORCE platform gives it noticeably more muscle than 20V budget trimmers. That matters along fence lines and ditches where grass grows thick and wiry, and it means fewer passes to finish the job. A brushless motor runs efficiently and quietly, so you can trim early on a weekend without the drone of a two stroke engine.
The straight shaft is a real advantage for a lightweight tool. It reaches under shrubs, decks and fences more easily than curved shafts, and it suits taller users who would otherwise hunch over. Because there is no engine at the end of the shaft, the balance is better than a gas trimmer of similar reach, which reduces shoulder strain.
The kit includes a 56V battery and charger, so it is ready to go out of the box. Larger capacity batteries for very big properties are sold separately, and the price is higher than big box brands. For owners who want a trimmer that feels professional without the weight of gas, it is worth it.
Another benefit is the eFORCE family itself. The same 56V battery runs other ECHO cordless tools such as hedge trimmers and blowers, so a homeowner who starts with this trimmer can build a quiet, gas free tool set over time without collecting a drawer full of different chargers.
Pros
- Light yet powerful 56V system
- Wide 16 inch cutting path
- Straight shaft reaches under obstacles
- Brand known for commercial grade build
Cons
- Larger batteries sold separately
- Higher price than big box brands
Who Should Buy It
The ECHO suits owners of medium to large yards who want real cutting power in a light, quiet tool. At around $250 with battery and charger, it is our best overall pick.
2. BLACK+DECKER 20V MAX EASYFEED String Trimmer and Edger LSTE523: Best Value
- Power: 20V MAX lithium ion
- Cutting width: 12 inches
- Line feed: EASYFEED
- Speed: 2 speed control
- Modes: trimmer and edger
- Kit: 1 battery and charger included
Why We Picked It
For small yards and light trimming on a budget, the BLACK+DECKER LSTE523 is one of the easiest tools to recommend. It belongs to the 20V MAX family, which is among the lightest class of cordless trimmers, and it handles the everyday jobs most homeowners face: tidying along the patio, around the mailbox and next to garden beds.
EASYFEED line advance means you do not have to bump the head on the ground or stop to pull line by hand, which keeps the session moving. The two speed control is more useful than it sounds. Use the lower speed for light grass around flower beds to stretch runtime, and switch to the higher speed for thicker patches.
The tool also converts from trimmer to edger, so you can clean up the line along a sidewalk or driveway without buying a separate edger. That two in one design is a big reason it remains so popular with first time homeowners, and it suits anyone who wants a simple, light tool that covers the basics.
It is not built for thick brush or large lots. A 20V battery runs out sooner than a 40V or 56V pack, so big properties may need a second battery, and dense weeds call for a stronger trimmer.
The 20V MAX battery is the other quiet advantage. BLACK+DECKER sells a wide range of light yard and household tools on the same platform, from hedge trimmers to sweepers and drills, so the battery can earn its keep year round instead of sitting on a shelf between mowing days.
Pros
- Very light and easy to handle
- Trimmer and edger conversion
- EASYFEED line advance and 2 speeds
- Large base of owner reviews
Cons
- Not for thick brush
- Short runtime on big yards
Who Should Buy It
The BLACK+DECKER suits small yards, townhomes and anyone who wants a light, simple trimmer and edger. At around $110, it is our best value pick.
3. WORX 20V 12 Inch 3 in 1 String Trimmer, Edger and Mini Mower WG170: Best Budget Pick
- Power: 20V Power Share, battery and charger included
- Cutting width: 12 inches
- Modes: trimmer, edger and mini mower with 90 degree pivot head
- Line feed: Command Feed push button
- Weight: 5.5 pounds
- Comfort: 7 position adjustable handle, telescopic shaft, dual support wheels and flower guard
Why We Picked It
At just 5.5 pounds, the WORX WG170 is the lightest trimmer on our list and a natural fit for seniors and small yards that need an ultra light tool. If a standard trimmer feels heavy after ten minutes, this one is likely to change your mind.
It is also more versatile than its size suggests. A 90 degree pivoting head lets you switch between trimming, edging and mini mowing, and it adapts to slopes and awkward spots. Dual support wheels guide the head along sidewalks and patios for straight edging lines, while an integrated flower guard protects plants when you trim close to beds.
The Command Feed button is a highlight. Press it and fresh line comes out electronically, so there is no bumping, no stopping and no wasted string. A 7 position adjustable handle and telescopic shaft fit users of different heights, and the shaft collapses for storage in a small shed or garage.
The trade offs are a narrow cutting path and limited power for tall, thick grass. It is designed for routine homeowner trimming and edging on small to medium yards, not for clearing overgrown lots.
Pros
- Featherweight at 5.5 pounds
- Command Feed push button line feed
- Converts to a wheeled edger and mini mower
- Very low price
Cons
- Small 12 inch swath
- Limited power for tall grass
Who Should Buy It
The WORX suits seniors, anyone with limited strength and owners of small yards who value low weight above all. At around $75, it is the best budget option.
Why Weight Matters More Than You Think
A trimmer is held at arm's length for the whole job, often with the head swinging side to side. Even a couple of extra pounds adds up over half an hour.
Weight vs power trade off
Lighter trimmers usually have smaller batteries and narrower cutting paths. Higher voltage models cut faster but weigh more. The sweet spot for most homeowners is the lightest tool that still handles the thickest weeds in their yard without repeated passes.
Balance and ergonomics
Balance matters as much as total weight. A trimmer with the battery near your hands feels lighter than one with weight at the far end. Adjustable handles, telescopic shafts and a shoulder strap all reduce strain.
Who benefits most
Seniors, people with arthritis or back problems, smaller users and anyone who trims every week benefit most from a light tool. Our guide to the best weed eater for seniors focuses on that need.
Technique helps any trimmer feel lighter. Let the line do the cutting instead of pushing the head into the grass, work in short sweeps from side to side, and keep the head slightly tilted so the line tips do most of the work. Trim when the grass is dry, because wet clippings add drag and drain the battery faster. Taking a short break every fifteen minutes is also kinder to your shoulders than one long push.
How to Choose the Best Lightweight Weed Eater
These features separate a light trimmer you will enjoy using from one that ends up in the back of the shed. Use them to find the best lightweight weed eater for your yard, or compare all types in our guide to the best string trimmer.
Gas vs Battery Power
Battery trimmers are lighter, quieter and start instantly, with no fuel or maintenance. Gas trimmers offer more power and runtime but weigh more and vibrate. For anyone shopping for the best lightweight string trimmer, battery is almost always the right choice.
Cutting Swath and Line Diameter
A 12 inch path suits small yards, while 13 to 16 inches covers more ground per pass. Thicker line cuts tougher weeds but needs more power. Check what line size the trimmer accepts before buying spools. Twisted or shaped line cuts more cleanly than round line of the same diameter, which helps a light trimmer punch above its weight.
Straight vs Curved Shaft
Straight shafts reach under shrubs and fences and suit taller users. Curved shafts are shorter and easier to control for small spaces and shorter users.
Weight and Balance
Compare weight with the battery installed. A well balanced 8 pound trimmer can feel lighter than a poorly balanced 7 pound one.
Line Feed System
Bump feed is simple, automatic feed reduces interruptions and push button feed gives precise control with no bumping. Easy reloading matters too, because changing line is the most annoying trimmer chore.
Edging Mode and Attachments
Many light trimmers rotate to edge along sidewalks, and some add wheels or a mini mower mode. If crisp edges matter, see our picks for the best string trimmer for edging.
Runtime and Battery Ecosystem
Check amp hours and whether the battery fits your other yard tools. A shared platform makes a spare battery more useful and saves money over time.
FAQs About Lightweight Weed Eaters
How long does a string trimmer last?
A quality battery string trimmer often lasts many seasons of homeowner use, though the battery may need replacing after several years. Cleaning grass from the head and guard, storing the battery indoors and avoiding overloading the motor in thick brush all extend its life.
Is a string trimmer worth the money?
Yes, for almost every yard with a lawn. A trimmer reaches the edges, fence lines and corners a mower cannot, which is what makes a lawn look finished. A light battery model is worth it even for small yards because it takes only minutes to use.
How much should I spend on a string trimmer?
Light 20V trimmers with a battery cost around $75 to $130. Midrange 40V models run around $150 to $230, and premium 56V or 80V kits cost around $250 to $350. Spend more for large yards or thick weeds. Our guide on how much does a weed eater cost has more detail.
How do I maintain a string trimmer?
Remove the battery, then clear grass and debris from the head, guard and air vents after each use. Replace line before it runs out, check the line cutter blade on the guard and store the battery indoors at moderate temperature over winter.
Final Verdict
The ECHO eFORCE 56V DSRM 2100 is the best lightweight weed eater for most yards, combining a 16 inch cutting path and strong battery power with a light straight shaft. The BLACK+DECKER LSTE523 is the value pick for small yards that also need edging, and the WORX WG170 is the featherweight choice for seniors and anyone who wants the lightest tool possible.
