Side by side

Spec comparison

One maker can sell trimmers on three battery systems, and the correct choice follows the batteries you own more than any spec on the trimmer. A bare tool on the right platform is a bargain, and the wrong platform is an expensive mistake.

Beyond the platform, the real differences are how the motor handles load, whether you want one head or a system of attachments, and how big a lawn you have. This guide compares five distinct machines from the range.

Before you buy

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

  1. 01

    Which battery family you own

    Makita sells string trimmers on 18V LXT, two LXT packs at once for 36V and 40V XGT. LXT packs fit a wide range of tools, while XGT is newer and heavier duty. Choose the family you own or plan to build on, since a bare tool is only cheap with the right pack. If you are starting from nothing, ask which other tools you are likely to buy, because the battery is the real long-term cost. A household with a drill and blower on LXT should stay there.

  2. 02

    Torque management

    The GRU01M1 and XRU15PT have Automatic Torque Drive, which shifts between 3,500 and 6,500 RPM, and the XRU15PT adds three fixed speeds. A motor that adjusts itself saves charge in easy grass and adds power in tough growth. The simpler XRU23SM1 runs at a fixed 6,000 RPM maximum. That is fine for ordinary grass, but on a mixed lawn the automatic modes save real charge. If you only cut flat turf, the extra control is nice to have rather than necessary.

  3. 03

    Swath and head size

    The GRU01M1 cuts 15 inches while the XRU23SM1 and the couple shaft attachment cut 13. A wider swath covers ground faster but needs more torque. Match it to your lawn. On a small lot the extra two inches is a handicap around beds, while on open ground it trims a noticeable amount from each mow.

  4. 04

    One battery or two

    The XRU15PT and XRU18Z use two 18V LXT packs at once. That gives more power but halves the number of sessions you can run on your battery stock. Count your packs before you choose a 36V tool. If you own only two, you will have nothing to swap in when they run flat. Four packs is the practical minimum for an afternoon of dual-battery work.

  5. 05

    Single head or system

    The XUX02SM1X4 is a power head with a trimmer and a pole saw attachment. A single trimmer is cheaper and lighter. Choose a system only if you will use other attachments. Most owners end up using one or two, so be honest about what you will actually own, and avoid paying for a shaft that will live on a shelf.

  6. 06

    Kit or bare tool

    The GRU01M1, XRU23SM1, XRU15PT and XUX02SM1X4 are kits and the XRU18Z is bare. A kit gives you a battery and charger, and a bare tool saves money only if you own packs. Check the listing title for the words tool only, since a bare model number and a kit number differ by a single letter and suffix.

The 5 best makita cordless string trimmers, explained

Makita GRU01M1 40V XGT Brushless 15 in. String Trimmer Kit, 4.0Ah
40V XGT15 in. swathTorque Drive4.0Ah kit
Check price on Amazon
Best for: Large lawns and thick growth for XGT owners or newcomers.

The XGT trimmer is the strongest single-battery Makita here, and its standout feature is the Automatic Torque Drive mode. The motor shifts between 3,500 and 6,500 RPM on its own, giving added power when the line meets heavy growth and extended runtime when it is in easy grass. An outer rotor brushless motor provides the torque.

The maker also claims the XGT's digital communication between tool and battery gives up to twice the sustained power under load, a relative claim that points to less power fade as the pack drains. That matters on a long, thick job, where cheaper trimmers lose speed as the battery sags.

The kit includes a 4.0Ah XGT battery and charger. XGT is a separate family from the 18V LXT packs, so it is the right choice only if you plan to build on it or already own the packs. Keep the head clear of wrapped grass, use fresh line and store the battery indoors. In practice the automatic mode means you can leave the trigger alone and let the tool decide, which suits people who would otherwise run at full speed all session. It is the Makita to buy when you expect one tool to handle both the lawn and the overgrown corners.

What works

  • Automatic Torque Drive shifts 3,500 to 6,500 RPM
  • Outer rotor brushless motor adds torque
  • XGT digital communication reduces power fade
  • Kit with 4.0Ah battery and charger

Watch out for

  • XGT packs do not fit 18V LXT tools
  • Heavier than the 13 inch LXT trimmer

18V LXT13 in. swath6,000 RPM4.0Ah kit
Check price on Amazon
Best for: Typical lawns and owners of 18V LXT batteries.

The XRU23SM1 is the sensible centre of the range. A BL brushless motor spins the head at up to 6,000 RPM, the swath is 13 inches, and the kit includes a 4.0Ah 18V LXT battery and charger. The maker claims up to an hour of runtime on that pack, a figure that should be read as a best case.

The point of this tool is the platform. 18V LXT batteries run a very wide range of Makita tools, including drills, blowers and saws, so a household with a few of them already owns the battery, and the bare version, the XRU23Z, saves money. For a newcomer, the kit is the right buy.

The listing's low-maintenance points apply to any battery trimmer: no gas, no oil mixing, no pull cord and low noise. It is a quiet, steady machine for lawns up to half an acre. Keep the line fresh and clear the head after each use. If you want a little more run time, a 5.0Ah LXT pack fits the same tool and adds about a quarter more capacity. Because LXT is the largest family, spare packs and chargers are easy to find at most tool dealers.

What works

  • BL brushless motor up to 6,000 RPM
  • Up to 1 hour of runtime claimed
  • 4.0Ah battery and charger included
  • Runs on the wide LXT battery family

Watch out for

  • 13 inch swath is average
  • Not built for heavy brush

36V (18V x2)Brushless3 speeds5.0Ah kit
Check price on Amazon
Best for: LXT owners who want more power without a new platform.

This trimmer uses two 18V LXT batteries at once, giving 36V of drive from the same packs that run Makita's drills and blowers. That is the clever part: no new platform, just a bigger tool. An outer rotor brushless motor with a direct drive provides high power and torque.

It offers three speed options at 3,500, 5,300 and 6,500 RPM for power management, plus an Automatic Torque Drive mode that shifts between 3,500 and 6,500 RPM for extended run time or added power. That is more control than any other Makita trimmer here.

The kit comes with 5.0Ah batteries. Two packs per session is the cost of the extra power, and the tool is heavier as a result. It makes the most sense for someone who already owns four or more LXT batteries and wants to use them in a bigger trimmer. Work out how many sessions your pack stock will cover, since two packs in use means two packs to charge. A third and fourth pack turn it into a tool you can run all afternoon, which is exactly the case for owning it.

What works

  • Runs on two common 18V LXT batteries
  • Three speeds plus Automatic Torque Drive
  • Outer rotor direct-drive brushless motor
  • 5.0Ah batteries in the kit

Watch out for

  • Uses two batteries per session
  • Heavier than single-battery models

Makita XRU18Z 36V (18V x2) LXT Brushless String Trimmer, Tool Only
36V (18V x2)Brushless30cc claimTool only
Check price on Amazon
Best for: LXT owners who want a bare heavy-duty trimmer.

The XRU18Z is a bare, dual-battery trimmer for people who already own LXT packs. The maker claims power equivalent to a 30cc gas string trimmer, a comparison that is a marketing label but places it in the heavier class. The BL brushless motor provides high power and increased torque, and the tool is free of gas, emissions, oil mixing and pull starts.

Because it is sold without batteries, it is the cheapest route to a strong trimmer if you own four LXT packs. It lacks the kit's batteries and the three-speed control listed for the XRU15PT, so it is a plainer tool.

If you do not own LXT packs, buy the kit. Keep the head clear of grass and store the batteries indoors. Treat the gas comparison as a pointer to the class of tool and not a measured output, and judge it by how it handles your own growth. For a large property it is a credible gas replacement for people who already own the packs.

What works

  • 30cc gas-class output claimed
  • BL brushless motor with high torque
  • Runs on two LXT batteries
  • No gas or pull start

Watch out for

  • Battery and charger sold separately
  • Needs two batteries per session

Makita XUX02SM1X4 18V LXT Couple Shaft Power Head Kit with 13 in. Trimmer and Pole Saw
18V LXTCouple shaft7,000 RPMTool-less attachments
Check price on Amazon
Best for: Gardeners who want one power head for several attachments.

This kit sells a power head, not a trimmer. A BL brushless motor delivers up to 7,000 RPM with the 13 inch string trimmer attachment, and the head also drives other attachments, including a 10 inch pole saw. A lever style lock system lets you swap attachments without tools.

That makes it a system: one motor and one battery, with different shafts for trimming, pruning and more. The value is real only if you will use more than one attachment, because the power head and battery cost more than a single trimmer kit.

It suits someone with a mixed garden who dislikes storing a separate machine for each task. Check the lever lock before each use, wipe the attachments after use and store the battery indoors. Lever locks wear with use, so keep the contact faces clean and free of grit. A power head with several attachments is most useful if you keep them together in one bag or on one rack.

What works

  • One power head drives several attachments
  • Brushless motor up to 7,000 RPM
  • Lever lock swaps attachments without tools
  • Runs on 18V LXT batteries

Watch out for

  • Costs more than a single trimmer kit
  • Value depends on using other attachments

Spec sheet decoder

What the numbers on the box really mean

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

Automatic Torque Drive

A mode in which the tool shifts speed automatically between low and high based on load. It saves charge in easy grass and adds power in tough growth. The result is steadier cutting without you touching a switch, which is the main advantage for anyone who finds speed settings fiddly.

Watch forThe GRU01M1 and XRU15PT shift 3,500 to 6,500 RPM.

Outer rotor brushless

A brushless motor design with the rotor on the outside, which gives high torque at low speed. A larger rotor diameter acts like a longer lever, so the motor pulls through thick growth without needing a high RPM.

Watch forListed on the GRU01M1 and XRU15PT.

36V (18V x2)

Two 18V LXT batteries used together to give 36V. It adds power without a new platform. The cost is that both packs drain together, so a weak pack in the pair limits the whole session.

Watch forXRU15PT and XRU18Z.

Gas equivalent

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

Watch forThe XRU18Z claims 30cc.

Couple shaft

A power head that accepts different shafts and attachments, secured by a lever lock. It is the same idea as a multi-tool: one motor and battery, many heads.

Watch forXUX02SM1X4.

Methodology

How We Evaluated These Makita Cordless String Trimmers

Motor and torque

We compared motor type and torque management. The GRU01M1 and XRU15PT with Automatic Torque Drive scored highest. We relied on the listed features and did not run our own measurements. Where the listing states a relative claim, such as up to twice the sustained power, we treated it as a direction and not a number.

Platform

We looked at which battery family each tool uses and how widely it is used. LXT scored high for breadth and XGT for power. A platform with many tools lowers the cost of your next purchase, which counts for more over a decade than a single spec.

Kit contents

We compared whether a battery and charger come in the box. The kits scored higher than the bare XRU18Z. A kit that includes a charger and battery removes the compatibility guesswork, which is the commonest source of buyer regret with bare tools.

Versatility

We considered attachments and speed modes. The couple shaft and the three-speed XRU15PT scored well. We gave credit to features that save effort in practice, such as tool-less attachment swaps, and ignored ones that only add to the spec sheet.

Ownership

We considered parts support and battery availability. Makita's dealer network scored well. Service points, spare lines and batteries are widely available, which keeps these tools working in year six.

LXT vs XGT

LXT

The XRU23SM1, XRU15PT, XRU18Z and XUX02SM1X4 run on 18V LXT. The packs fit a very wide range of tools.

XGT

The GRU01M1 runs on 40V XGT. It is newer and aimed at heavier work.

Choose LXT if you own those packs and XGT for heavy-duty plans.

For Thick Growth Specifically

Look for

Look for a brushless motor with torque management and a wide swath. Battery capacity and fade matter more than peak RPM.

In this comparison

The Makita GRU01M1 and XRU15PT both use outer rotor brushless motors with Automatic Torque Drive.

When to Spend More

Spend more if

Spend more if your lawn is large or your growth thick. The GRU01M1 is the strongest.

Save if

Save if your lawn is ordinary. The XRU23SM1 is enough.

Ownership

Maintenance schedule

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

TaskIntervalWhy it matters
Clear grass from the headAfter each usePacked grass strains the motor and holds moisture against the housing. Clear it with the battery removed and brush the vents.
Replace the lineWhen shortShort line cuts a narrow swath and loads the motor unevenly. Use the diameter the head is rated for and keep a spare spool with the tool.
Check the lever lockBefore each useOn the couple shaft a loose lock lets the attachment wobble and can wear the mating faces. Click it fully home and wipe the faces clean before each swap.
Store batteries indoorsWinterCold lowers capacity and a pack left flat can fail to recharge. Keep them at half charge in a dry room.
Inspect the shaft and guardEach seasonA bent guard lets line wrap around the head and stall the motor. Straighten or replace it, and check the shaft for play at the same time.

FAQ

Frequently Asked Questions

Should I choose LXT or XGT?

Choose the family you own. If you own neither, the XRU23SM1 kit is simple and the GRU01M1 is for heavier work.

What is Automatic Torque Drive?

A mode that shifts the motor speed automatically with load. It saves charge in easy grass and adds power in thick growth. It is not a different power level, only a smarter use of the same battery.

What does 36V (18V x2) mean?

Two 18V LXT batteries are used together. It adds power without a new platform but needs two packs per session.

Is the couple shaft worth it?

Only if you use more than one attachment. A single trimmer is cheaper. If you already own a pole saw or hedge trimmer on another shaft, the system adds little.

How long does a battery last?

Makita claims up to an hour on 4.0Ah for the XRU23SM1. Thicker growth shortens that. The XGT kit does not state a runtime in the data, so treat any figure for it as an estimate and plan a spare pack for large lawns.

Can I use bare tools?

Yes, if you own the right batteries. Otherwise buy a kit. Make sure the pack is the right family, since an 18V LXT pack will not run a 40V XGT tool.
