Side by side

Spec comparison

This maker is known for convertible trimmers that double as edgers, and its range runs from a very light budget tool to a long-shaft model with a carbon fibre shaft. The common thread is a shared battery system and a feed mechanism that works without bumping.

The sensible way to choose is by lawn size and by how much you value extra modes. This guide sorts six models from the simplest to the most capable and says where the cheaper ones stop being enough.

Before you buy

6 Criteria to Look For Before Buying a WORX Cordless String Trimmer

  1. 01

    20V or 40V platform

    Worx trimmers use 20V for the WG154, WG163, WG170, WG173 and WG176, and 40V for the WG183 and WP925. The 20V packs are shared across a very wide range, and 40V gives more energy for bigger swaths. Choose the platform before the trimmer. If you already own a Worx 20V battery from a blower or mower, a 20V trimmer is the obvious match. Buying into 40V only for one trimmer is the least economical route.

  2. 02

    Brushless or brushed

    The WG173 and WG176 are brushless, which runs cooler and holds speed under load. The WG154, WG163 and WG170 are lighter-duty brushed-class tools. For a half-acre or more, brushless helps. The gain is longer runtime and fewer parts to wear, so it pays back mainly in frequent use. On a small lawn trimmed twice a month, you will not feel the difference.

  3. 03

    Feed system

    Command Feed and auto feed on the WG154, WG163, WG170, WG173 and WG183 remove bumping, while the WG176 uses a bump feed. Push-button feed is gentler on hard edges. Bump feed handles heavier line. If most of your trimming is along a driveway or patio, prefer push-button feed, because bumping the head on concrete is the quickest way to chew up a spool.

  4. 04

    Swath size

    The WG154 cuts 10 inches, the WG163 and WG170 12, the WG173 and WG183 13 and the WG176 and WP925 up to 15. The WG176 lets you switch between 13 and 15 inches. A wider swath covers ground faster but drains the battery. On a small lot the wide setting is a handicap around beds, so a narrower tool is often the better pick. Size the swath to the awkwardness of your garden as well as its area.

  5. 05

    Modes and adjustability

    The WG170 has 7 handle adjustments and 6 head settings, and the WG173 and WG170 add a mini mower mode. More modes help small yards, but each adds a joint to maintain. Choose the modes you will use. A mini mower mode is a fun extra, but if you already own a mower it will gather dust. Be honest about which modes you will reach for each month.

  6. 06

    Weight and shaft

    The WG154 is 4.2 pounds and the WP925 has a carbon fibre shaft. A lighter tool allows longer sessions. Pick weight for your stamina and shaft design for balance. A carbon fibre shaft costs more, but it is the one feature here that you feel in the arms after thirty minutes.

20V brushless13 or 15 in.21cc claimBump feed
Check price on Amazon
Best for: Mid to large lawns where a choice of swath helps.

The WG176 is the Worx to buy for a larger lawn, and the feature that stands out is the adjustable cutting width. You can switch between a 13 inch circle for longer runtime and a 15 inch circle for faster coverage, a choice that most trimmers do not offer. A brushless motor provides the power, and the maker says it delivers the performance of a 21cc gas trimmer, a marketing comparison that points to the class of the tool rather than a measured output.

The head is a bump feed, which is simple and works with heavier line, but you tap the ground to advance it and that wastes line on hard surfaces. That makes it a better match for lawn grass and rough edges than for patio paving. The tool also converts, according to the listing, and is light and ergonomic for a 15 inch machine.

On a 20V battery the wide setting will drain the pack quickly, so a spare battery is a sensible purchase for a half-acre. Clear grass from the head after each use, fit fresh line and store the battery indoors. Use the 13 inch setting for edges and beds and the 15 inch setting for open ground, since changing it mid-job is easy and saves charge. Owners who mow a large lot often keep a second 20V pack charged and swap midway.

What works

  • Switchable 13 or 15 inch cutting diameter
  • Brushless motor with a 21cc gas-class claim
  • Bump feed works with heavier line
  • Light and ergonomic for its size

Watch out for

  • Bump feed wastes line on hard ground
  • Wide setting drains a 20V battery

Worx WG163 20V 12 in. 2-in-1 Cordless String Trimmer and Edger
20V class12 in. swathCommand Feed90 degree head
Check price on Amazon
Best for: Small lawns and anyone who dislikes bumping a head.

The WG163 is the simple, low-cost Worx that handles most small gardens. It converts from trimmer to edger in seconds, and the head tilts 90 degrees so you can use it on sloped terrain and tough-to-reach places. A push-button Command Feed system gives instant line without bumping the head.

The design philosophy is to remove annoyances: no tapping, no tools to switch modes and a weight that does not tire you. The cost is power, since a 12 inch swath on a brushed 20V motor is for lawn edges and light weeds.

The 20V battery is shared across many Worx tools, which means a second battery or a hedge trimmer costs less later. Clean the pivot after use, because grit makes the head stiff, and store the pack indoors. If your lawn grows past a quarter acre, step up to the WG173 or WG176 rather than adding a second battery here, since a brushed motor wastes more of each charge as heat. For borders and lawn edges, nothing in the range is simpler to live with.

What works

  • Converts to an edger in seconds
  • Head tilts 90 degrees
  • Command Feed adds line with a button
  • Shared 20V battery system

Watch out for

  • Brushed motor with light power
  • Single battery is short on larger lawns

20V brushless13 in. swath3-in-14.0Ah
Check price on Amazon
Best for: Mid-sized lawns that need three modes and a big battery.

The WG173 is the WG163's bigger, brushless cousin. A high-torque brushless motor and a 4.0Ah battery deliver what the maker calls gas-like power, and a 90 degree pivot head lets you trim, edge and mini-mow. An electronic push-button Command Feed advances line without bumping.

The maker also claims three times the cutting area of the earlier tool, which is a way of saying the swath is bigger. A 13 inch swath and 4.0Ah pack make it the sensible pick for a mid-sized lawn.

The mini-mower mode suits small banks, not full lawns, so treat it as a convenience. Keep the pivot and the wheel clean and store the battery indoors in winter. Because the 4.0Ah pack also fits other Worx 20V tools, it makes a good first purchase if you plan to add a blower or hedge trimmer. Treat the gas-like claim as a description of the class and judge the tool on your own growth.

What works

  • Brushless motor with a 4.0Ah battery
  • 13 inch swath
  • Command Feed push-button feed
  • 3-in-1 with a 90 degree pivot

Watch out for

  • Mini mower mode suits only small areas
  • 20V platform limits thick growth

Worx WG170 20V 12 in. 3-in-1 Trimmer, Edger and Mini Mower
20V class12 in. swath7 handle settings6 head settings
Check price on Amazon
Best for: Small lawns with awkward corners and users of different heights.

Worx fits this trimmer with 7 handle adjustments and 6 rotating head settings, which makes it the most adjustable tool in the range. That matters for comfort and for getting the head into awkward places such as under shrubs or along fences. It transforms between a precision string trimmer, an in-line edger and a nimble mini mower.

The proprietary Command Feed lets you add more line as needed by pressing a button, so there is no bumping. A 12 inch swath is a good size for a small to medium lawn.

The tool is a light 20V machine, so it is for light growth. The more adjustable a tool is, the more joints it has, so check the locking points are tight before each session and clean them after use. A tool that adjusts to seven handle positions is a good choice for a household with different users, as each person sets it once and forgets it. Write down the setting that suits you so you can return to it in seconds.

What works

  • 7 handle adjustments and 6 head settings
  • Trimmer, edger and mini mower modes
  • Command Feed push-button line
  • 12 inch swath

Watch out for

  • More joints to keep clean and tight
  • Light 20V power

Worx WG154 20V 10 in. 2-in-1 Cordless String Trimmer and Edger, 4.2 lb
20V class10 in. swath4.2 lbAuto feed
Check price on Amazon
Best for: Tight gardens and users who want the lightest tool.

The WG154 is the lightest and smallest Worx here at 4.2 pounds, with a compact 10 inch swath and an automatic line feed that advances line without bumping. It switches from string trimming to in-line edging in seconds, helping maintain grass and borders.

The small size is an advantage on tight gardens and for people who want a tool they can lift with one hand. It is a drawback on larger lawns, where a 10 inch circle means many more passes.

It is the cheapest way into the system, so it makes a good first tool or a second tool for detail work. Clear grass from the head, replace the line when it gets short and store the battery indoors. A very light tool encourages you to use it for quick jobs, so it tends to stay out by the back door where a heavier one would live in the shed. If you later outgrow it, the 20V battery still works in the bigger Worx models.

What works

  • 4.2 lb is the lightest here
  • Automatic line feed
  • Converts to an in-line edger
  • Compact 10 inch swath

Watch out for

  • Small swath is slow on open lawn
  • Light power for thick growth

Worx WP925 40V 15 in. String Trimmer and 530 CFM Leaf Blower Kit, Carbon Fiber Shaft
40V class15 in. swath530 CFM blowerCarbon fibre shaft
Check price on Amazon
Best for: Larger lawns with paved areas to clear.

The WP925 is the heavy-duty Worx. A 15 inch cordless trimmer with a carbon fibre shaft and a 530 CFM leaf blower share one 40V platform, and the maker says it can cut thick grass and weeds. The carbon fibre shaft is the notable part, because it reduces weight and improves balance during use.

The 40V platform provides more energy than the 20V models, which is what a 15 inch head needs. A blower at 530 CFM is one of the strongest in this guide and clears a driveway quickly.

It costs more because it includes two tools. If you only need a trimmer, the WG176 is the better value. Clear the blower intake, tap or feed the line as the head requires and store the battery indoors. Because one battery runs both tools, trim first and blow second so the pack is strongest for the trimmer's higher torque demand. A second 40V pack makes the kit far more practical on a large lot.

What works

  • 15 inch swath on a 40V platform
  • Carbon fibre shaft improves balance
  • 530 CFM blower included
  • Trimmer cuts thick grass, per the maker

Watch out for

  • Higher cost for two tools
  • 40V packs fit only the 40V range

What the numbers on the box really mean

The specs manufacturers lead with, translated into what they tell you about real-world performance.

Command Feed

A push-button line feed that adds line on demand without bumping. It uses a small motor or spring to release a measured length when you press, so you never run a short line by accident.

Watch forOn the WG163, WG170 and WG173.

Gas equivalent

A marketing comparison to an engine size. It is a rough guide only, because engines and battery motors deliver power in different ways and no standard defines the label.

Watch forThe WG176 claims 21cc.

Brushless

A motor with electronic switching and no brushes.

Watch forThe WG173 and WG176.

Switchable swath

A head that cuts a 13 or 15 inch circle. The smaller circle saves battery and puts less load on the motor, which helps in thick grass.

Methodology

How We Evaluated These WORX Cordless String Trimmers

Cutting capability

We compared swath, motor type and platform. The WG176 and WP925 led. We relied on the listing specifications, not on our own measurements. Relative claims such as three times the cutting area were treated as a direction and not an exact multiple.

Feed and convenience

We looked at feed systems and conversion. Command Feed and the pivot head scored well. A feature earned credit only if it removes a chore, such as tapping the head or switching tools.

Adjustability

We counted handle and head settings. The WG170 scored highest.

Battery value

We compared included packs. The WG173's 4.0Ah scored well.

Ownership

We considered how widely the batteries are used. The Worx 20V platform scored well for breadth. A battery that fits blowers, hedge trimmers and drills as well as trimmers is the best insurance against being stranded with a dead tool.

For Large Lawns Specifically

Look for

Look for a brushless motor, a wide swath and a large battery. Weight matters over a long session.

In this comparison

The Worx WG176 offers 15 inches with brushless power, and the WP925 adds 40V energy and a blower.

When to Spend More

Spend more if

Spend more if the lawn is large. The WG176 and WP925 are the strongest.

Save if

Save if the lawn is small. The WG154 or WG163 is enough.

Ownership

Maintenance schedule

The upkeep that decides whether this machine lasts two seasons or ten.

TaskIntervalWhy it matters
Clean the pivot and wheelAfter each useGrit stiffens the head and stops the wheel turning. Brush it clean and add a drop of light oil to the pivot pin once a season.
Clear grass from the headAfter each usePacked grass strains the motor and holds moisture against the housing. Clear it with the battery removed and let the head dry before you store it.
Replace the lineWhen shortShort line cuts a narrow swath and loads the motor unevenly. Keep a spare spool with the tool.
Check handle locksEach seasonOn adjustable models a loose lock lets the head wobble and wears the clamp faces. Tighten each lock fully and test the shaft by pushing sideways before you switch on.
Store batteries indoorsWinterCold lowers capacity and a pack left flat for months may refuse to charge. Keep them at half charge indoors.

FAQ

Frequently Asked Questions

Which Worx trimmer is best for a small lawn?

The WG163 or WG154. Their narrow swaths are easy to steer, and the push-button feed avoids bumping.

What does Command Feed do?

It adds fresh line when you press a button. It removes the need to bump the head on the ground.

Is the WG176 really gas equivalent?

The maker claims 21cc gas performance. It is a marketing comparison, but the brushless motor and 15 inch swath put it in the heavier class. Judge it on how it handles your own growth in the first few weeks.

Are the 20V and 40V batteries interchangeable?

No. They are separate systems. Choose the platform before the tool.

How long does a battery last?

It depends on swath and growth. A 4.0Ah pack on the WG173 lasts longer than a smaller pack on the WG154.

Is the mini mower mode useful?

On small banks and corners, yes. It is not a replacement for a mower.
