How we chose string trimmers with attachments

Best string trimmers with attachments for different yard jobs
The Milwaukee QUIK-LOK model leads for system breadth, while the other picks suit buyers who prefer an included battery, a different voltage platform or a bundled set of yard tools. Choose by the attachments you expect to use and the batteries you already own.
Milwaukee M18 FUEL Trimmer with QUIK-LOK: Best for a broad attachment system
- Compatible with 13 QUIK-LOK attachments
- 16 in cutting width
- Brushless motor
The QUIK-LOK system supports a wide range of compatible attachments, so one power head can serve more yard tasks. The trimmer is sold as a bare tool.
Pros
- Works with 13 QUIK-LOK attachments
- 16 in cutting width
Cons
- Battery and charger are not included
The Milwaukee M18 FUEL Trimmer with QUIK-LOK is the strongest fit if you want one power head that can work with multiple tools. Milwaukee says the POWERSTATE brushless motor delivers more power than 31cc gas powerheads, and the QUIK-LOK system is compatible with 13 Milwaukee attachments.
Its 16 in cutting width gives you a broad trimming path, and the stated weight is 13.2 lb. The trimmer is a bare tool, so factor in a compatible M18 battery if you do not already have one.
Milwaukee's attachment system is the main reason to choose this model. Before buying, make a short list of the tools you actually want, then confirm each one is a QUIK-LOK attachment.
Choose it for a wide range of compatible Milwaukee tools, especially if you already use M18 batteries. Look elsewhere if you need a battery and charger in the box.
DeWalt 60V 17-Inch Attachment-Capable Trimmer Kit: Best for an included battery and charger
- Universal attachment capability
- 15 in or 17 in adjustable swath
- Battery and charger included
This kit includes a 60V battery and charger, plus a variable trigger and high or low speed control. Its adjustable swath lets you choose between 15 in and 17 in.
Pros
- Battery and charger included
- Adjustable cutting width
Cons
- Heaviest listed kit here
The DeWalt 60V 17-Inch Attachment-Capable Trimmer Kit suits buyers who want a battery-powered setup with an included battery and charger. It accepts DeWalt universal attachments, and its swath adjusts between 15 in and 17 in.
A variable trigger and high or low speed control let you adjust the tool for the task. DeWalt also describes the motor as brushless, and the stated weight is 15 lb.
The kit uses a 60V FLEXVOLT battery that DeWalt says also works with its 20V MAX tools. Its weight is higher than the Milwaukee M18 options here, so consider how long you'll carry it at a time.
Choose it if you want the battery and charger included and like the flexibility of an adjustable cutting width. Confirm that the DeWalt attachments you want fit its universal connection.
Ryobi 40V Attachment-Capable Trimmer Kit: Best for a 40V starter kit
- 40V battery and charger included
- 13 in to 15 in adjustable width
- Expand-It attachment capability
The included 40V battery and charger make this a ready-to-start kit. It accepts Ryobi Expand-It attachments and other universal gas attachments.
Pros
- Battery and charger included
- Adjustable cutting width
Cons
- Heavier than the Milwaukee M18 FUEL trimmer
The Ryobi 40V Attachment-Capable Trimmer Kit is a practical pick if you need a battery and charger included and want to use Expand-It attachments. It accepts Ryobi Expand-It tools as well as other universal gas attachments.
Its 13 in to 15 in adjustable cutting width lets you favor a narrower path or wider coverage. The Reel-Easy bump-feed head is designed for faster line reloading, and the variable speed trigger gives you cutting control.
The stated weight is 13.9 lb. Ryobi recommends this trimmer for yards up to 1 acre, though yard conditions and attachment use can affect how much work a battery can handle.
Choose this kit for a 40V starting setup and access to Ryobi Expand-It tools. If you own Ryobi 40V batteries already, compare it with the tool-only carbon fiber option below.
Milwaukee M18 2825-20ST Attachment-Capable Trimmer (Tool Only): Best for M18 tool owners
- 14 in to 16 in cutting swath
- Works with multiple Milwaukee attachments
- Easy-load trimmer head
This tool-only M18 option works with multiple attachments, including an edger, articulating hedge trimmer and pole saw. Its cutting swath adjusts from 14 in to 16 in.
Pros
- Compatible with several attachments
- Adjustable cutting swath
Cons
- Battery and charger are not included
The Milwaukee M18 2825-20ST suits buyers who want an attachment-capable tool head without moving to another battery platform. This is a tool-only model, and its compatible attachments include an edger, articulating hedge trimmer and pole saw.
The cutting swath adjusts from 14 in to 16 in, and the easy-load head can take 0.080 in or 0.095 in line. Milwaukee lists speed ranges up to 6,201 rpm, and the stated weight is 12.7 lb.
This is a separate choice from the M18 FUEL QUIK-LOK model above, so check which attachment system matches the tools you plan to use. Its brushless motor is built for the power head, according to Milwaukee.
Choose it if you already own compatible M18 batteries and want a lighter stated weight than the DeWalt kit. The battery and charger are not included.
Greenworks 40V 16-Inch Attachment-Capable Trimmer: Best for Greenworks attachment options
- Compatible with 5 named attachments
- 16 in cutting width
- Brushless motor
Greenworks lists compatible edger, hedge, pole saw, cultivator and blower attachments for this 40V trimmer. It also includes a 4.0 Ah battery.
Pros
- Five compatible attachments are named
- 4.0 Ah battery included
Cons
- Heavier than the Milwaukee M18 options
The Greenworks 40V trimmer is a good match if its named attachments cover your yard needs. It works with five Greenworks PAC attachments: an edger, hedge trimmer, pole saw, cultivator and blower.
Its 16 in cutting width suits buyers who want a broad trimming path. Greenworks includes a 4.0 Ah battery, and the trimmer has two speed modes with a variable trigger.
The stated weight is 15.2 lb. Greenworks describes the motor as brushless and says its 40V battery platform powers more than 60 outdoor products, which may matter if you already own compatible Greenworks tools.
Choose it for the Greenworks attachment choices and included battery. Check that the exact PAC attachment model you want is compatible before building out the system.
Ryobi 40V Carbon Fiber Expand-It Trimmer: Best for a lighter tool-only option
- 7 lb tool weight
- Brushless motor
- Works with Ryobi Expand-It attachments
At 7 lb, this tool-only Ryobi option is the lightest pick in this group. Its battery and charger are not included.
Pros
- Lightest stated tool weight here
- Works with Ryobi Expand-It attachments
Cons
- Battery and charger are not included
The Ryobi 40V Carbon Fiber Expand-It Trimmer is the lightest pick by stated tool weight at 7 lb. It is sold without a battery or charger, and it works with Ryobi Expand-It attachments.
Its brushless motor and two-speed trigger add control options, while the carbon fiber-coated construction distinguishes it from the other Ryobi 40V pick here. Since the battery is not included, this model makes more sense if you already own Ryobi 40V lithium-ion tools.
The product description mentions possible uses such as an edger, blower and pole saw through available attachments. Check compatibility for each attachment before you buy.
Choose it if low tool weight matters and you have a compatible 40V battery. If you need a complete kit, the other Ryobi 40V option includes a battery and charger.
Ryobi ONE+ 18V Brushless Attachment-Capable Trimmer: Best for Ryobi 18V owners
- Works with Ryobi Expand-It attachments
- 15 in cutting width
- Brushless motor
This tool-only trimmer works with Ryobi Expand-It attachments and any Ryobi ONE+ 18V battery. The battery and charger are not included.
Pros
- Uses Ryobi ONE+ 18V batteries
- 15 in cutting width
Cons
- Battery and charger are not included
The Ryobi ONE+ 18V Brushless Attachment-Capable Trimmer fits buyers who already use Ryobi's 18V battery platform. It works with Ryobi Expand-It attachments, and its battery and charger are sold separately.
The 15 in cutting width is stated in the product details, and the tool weighs 11 lb. A brushless motor and Reel-Easy Plus bump-feed head with speed winder are also included features.
This model uses ONE+ 18V batteries, so it is distinct from Ryobi's 40V Expand-It trimmers. Check your battery label and attachment compatibility before choosing between the platforms.
Choose it if you want an Expand-It trimmer for your Ryobi ONE+ tools. Consider a kit instead if you need a battery and charger.
Wild Badger 40V Brushless 4-in-1 Trimmer and Brush Cutter: Best for a bundled multi-tool kit
- Includes trimmer, pole saw, hedge trimmer and brush cutter
- 40V 4 Ah battery and charger included
- 15 in cutting width
The kit includes four yard tools, a 40V 4 Ah battery and a charger. Its 18 lb stated weight is the highest among these picks.
Pros
- Four tools included
- Battery and charger included
Cons
- Heaviest stated weight here
The Wild Badger 40V Brushless 4-in-1 kit suits buyers who want several yard tools in one package. It includes a 15 in trimmer and edger, an 8 in pole saw, a 16 in hedge trimmer, and a 10 in brush cutter blade with 0.095 in line.
A 40V 4 Ah battery and charger are included. The stated weight is 18 lb, the heaviest among the picks here, so consider that before choosing a kit with several handheld tools.
This is a bundled set, not just a trimmer power head with optional attachments. That can save separate tool purchases when you need all four functions, but it may add tools you will not use.
Choose it for the included multi-tool set and battery. If you only need a trimmer with room to add one attachment later, a dedicated attachment system may be a better fit.
What to check before buying an attachment-capable trimmer
Check the attachment connection first, because systems vary by brand and model. A trimmer that accepts universal gas attachments may not fit every attachment you own, so confirm exact compatibility before ordering.
Battery details also change the value of a kit. The DeWalt, Ryobi 40V kit, Greenworks and Wild Badger picks include batteries, while several Milwaukee and Ryobi tool-only options require a compatible battery and charger.
Weight can help narrow the field if you carry a trimmer for long passes. The stated tool weights range from 7 lb for the Ryobi carbon fiber model to 18 lb for the Wild Badger kit, though the weights may not represent the same configuration.
For shaft shape and handling differences, read our straight shaft vs curved shaft trimmer guide. If you are comparing battery platforms, our string trimmer gas vs battery guide covers the main tradeoffs.
Which string trimmer with attachments should you choose?
Choose the Milwaukee M18 FUEL with QUIK-LOK if your priority is access to a broad attachment system. Pick DeWalt if you want a 60V kit with battery and charger, or Ryobi 40V if you want an included-battery option with Expand-It compatibility.
For a lighter stated tool weight, the Ryobi carbon fiber model is the standout, provided you have a compatible battery. For several tools in one box, the Wild Badger kit includes the most functions, while Greenworks names five separate compatible attachments.
The best string trimmer with attachments is the one that fits the tools you plan to use and the battery platform you can support. Start with those two checks, then compare weight and cutting width.

Frequently asked questions
What does attachment-capable mean on a string trimmer?
An attachment-capable trimmer lets you connect compatible tool heads to its power head. Depending on the system, those can include an edger, hedge trimmer, pole saw or cultivator.
Check the brand and system names before buying attachments, since a universal connection claim does not guarantee every attachment will fit.
Do attachment-capable trimmers include the attachments?
Not always. Several picks here are tool-only, while the Wild Badger kit includes a trimmer, pole saw, hedge trimmer and brush cutter.
Read the included-tools details and check whether you also need a battery and charger.
Can I use attachments from another brand?
Some trimmers accept universal gas attachments, but systems such as Milwaukee QUIK-LOK and Ryobi Expand-It have their own compatibility requirements.
Confirm the exact power head and attachment pairing before you buy. A shared voltage or brand name alone does not guarantee a fit.
Should I choose a kit or a tool-only trimmer?
A kit makes sense when you need its included battery and charger, while a tool-only trimmer can fit if you already own compatible batteries.
Compare the attachment system, included tools and stated weight too. A lower number of included parts can still suit you better if you already have them.
