The best straight shaft string trimmer for most yards is the EGO Power+ ST1623T, which combines an adjustable carbon fiber shaft with automatic line feeding and a 16-inch cutting swath. For attachments, compare the Greenworks 60V and Milwaukee QUIK-LOK; for gas, consider the Husqvarna 122LK.
A straight shaft can reach under shrubs and along fences where a curved shaft may be awkward. The right tool still depends on weight, power source, cutting width, line loading, and whether you want one tool or an attachment system.
If you're deciding which shape fits, read our straight shaft vs curved shaft trimmer guide. Our string trimmer buying guide covers power, weight, and line choices, while the best string trimmers with attachments roundup focuses on multi-tool systems.

How we chose these straight shaft string trimmers
We compared the stated shaft design, power source, cutting width, line system, attachment support, and included kit components. Our score weighs specs and features against what shoppers seeking a straight shaft trimmer are likely to value.
A shaft that reaches beneath shrubs can matter more than extra cutting width in a tight yard. For larger open areas, battery platform, runtime information, and line feeding may carry more weight.

The best straight shaft string trimmers by use
The EGO ST1623T leads for its adjustable shaft and automatic line system, while the other picks fit distinct needs such as attachments, gas power, or variable cutting width. Choose the feature that solves your most frequent trimming task.
EGO Power+ ST1623T 16-Inch Trimmer: Best for adjustable reach
- 16-inch cutting swath

The adjustable carbon fiber shaft helps you set a comfortable working length. LINE IQ feeds line automatically, and POWERLOAD winds it with a button.
Pros
- Adjustable shaft length
- Automatic line feed
- Button-operated line winding
Cons
- Cordless battery platform required
- Runtime varies with work and speed
The EGO Power+ ST1623T 16-Inch Trimmer is the top choice if you want to adjust shaft length and spend less time managing line. Its telescopic carbon fiber shaft adjusts to your height, and the 16-inch cutting swath covers a broad path around lawn edges and beds.
LINE IQ monitors line length and feeds it automatically for a continuous cutting swath. When you need to reload, POWERLOAD winds the line after you feed it through the head and press the button.
The included 4.0Ah battery provides up to 60 minutes of runtime, and EGO says it charges in 55 minutes with the included CH3200 charger. A digital variable speed selector lets you match speed to the task.
This is a strong fit for buyers who want automatic line feeding and already use, or plan to use, EGO 56V batteries. Its shaft is adjustable, but the unit remains a battery-powered tool with platform-specific batteries.

Cons
- 18.7 lb listed weight
- Attachment compatibility is limited to compatible Greenworks options
The Greenworks 60V 16-Inch Trimmer fits buyers who want a straight shaft tool that can take compatible attachments. Its 16-inch cutting path and brushless motor target thicker grass and larger yard tasks, while an adjustable shoulder strap helps distribute weight during longer sessions.
The Load N’ Go head is designed for quicker line reloading. Greenworks includes a 4.0Ah battery, charger, and spool, and says the battery works with more than 75 products in its 60V platform.
At 18.7 lb, it is the heaviest battery model in this group with a stated weight. Consider how long you'll hold it and whether the strap helps with your working style.
Choose this model if you want attachment options and are comfortable with its weight. For details on compatible add-ons, see our string trimmer attachment guide.
EGO Power+ ST1511T 15-Inch Trimmer: Best for simpler line loading

Cons
- 15-inch cutting swath
- Up to 45 minutes of runtime
The EGO Power+ ST1511T 15-Inch Trimmer is a good match if you want line reloading handled with a button but don't need the wider 16-inch path of the top pick. Its telescopic aluminum shaft adjusts for a more comfortable reach.
POWERLOAD winds the line after you feed it through the head. The kit includes a 2.5Ah battery and charger, and EGO states up to 45 minutes of runtime per charge.
This model uses a 15-inch swath and professional-grade 0.095 in line. It also has two speed settings, so you can choose between them for different trimming work.
Pick the ST1511T if an adjustable shaft and simple line winding matter more than maximum runtime. For an overview of cordless options, see our best cordless weed eaters.
Milwaukee M18 FUEL Trimmer with QUIK-LOK: Best for Milwaukee attachment users
- 16-inch cutting width
- Brushless motor
- Compatible with 13 QUIK-LOK attachments
- Bare tool
The QUIK-LOK system connects this trimmer to compatible Milwaukee attachments. It is sold as a bare tool, so account for the battery and charger separately.
Pros
- Works with 13 QUIK-LOK attachments
- 16-inch cutting width
- Brushless motor
Cons
- Bare tool
- Best fit for buyers already using compatible Milwaukee equipment
The Milwaukee M18 FUEL Trimmer with QUIK-LOK suits buyers who already use compatible Milwaukee attachments. Its 16-inch cutting width and brushless POWERSTATE motor provide the trimming base, and Milwaukee says the QUIK-LOK system works with 13 attachments.
This is a bare tool, so plan for a compatible battery and charger if you don't already have them. That makes it a more natural choice for a buyer already invested in the M18 system than for someone starting from scratch.
Choose it when the attachment system is part of your yard-care plan. If you only need a trimmer, a complete kit may be simpler.
Ryobi 40V Attachment-Capable Trimmer Kit: Best for adjustable cutting width
- 13 to 15-inch adjustable cutting width

- 13.9 lb listed weight

This combination suits a homeowner who wants one battery tool for trimming and compatible add-ons. The listed weight is 13.9 lb, so compare that with your ability to hold and guide the tool for a full session.
Pick Ryobi if adjustable width matters and the attachment system matches tools you plan to use. Our 40V vs 20V trimmer guide explains how to compare battery platforms.
Greenworks 80V 16-Inch Trimmer: Best for a bump-feed head
- 16-inch cutting width
- Brushless motor

- Variable speed trigger
A 16-inch path and bump-feed head suit buyers who prefer manual line advancement. This kit includes a 2.0Ah battery and charger.
Pros
- 16-inch cutting width
- Bump-feed line advancement
- Variable speed trigger
Cons
- 16 lb listed weight
- Not attachment capable
The Greenworks 80V 16-Inch Trimmer is a fit for buyers who prefer a bump-feed head and a wider cutting path. Its brushless motor, variable speed trigger, and 16-inch width suit open sections of lawn where you want to make fewer passes.
The 2.0Ah battery and rapid charger are included. Greenworks states a 30-minute charging time for this battery, and the trimmer uses a bump-feed head to advance line during work.
It weighs 16 lb, so buyers prioritizing a lighter tool should compare the weight with the other options. The model is not described as attachment capable, which makes it less flexible than several picks above.
Choose it if you want a straightforward 80V trimmer with bump-feed line advancement. Consider a lower-voltage kit if you already own compatible batteries and want to stay within that platform.

- 15.2 lb listed weight
- Attachment compatibility is limited to compatible Greenworks options
The Greenworks 40V 16-Inch Attachment-Capable Trimmer suits buyers who want a wide cutting path and add-on options in the Greenworks 40V platform. Its brushless motor and two speed modes offer a way to adjust the tool to trimming conditions.
Compatible attachments include an edger, hedge trimmer, pole saw, cultivator, and blower. It has a variable speed trigger and a 16-inch cutting width, giving you a mix of control and coverage.
The trimmer weighs 15.2 lb. Greenworks describes the 40V battery platform as covering more than 60 outdoor products, which can matter if you want to add other yard tools over time.
Choose it if platform compatibility and attachments rank above lower carry weight. See our best 40V string trimmers for more 40V options.
Husqvarna 122LK 17-Inch Straight Shaft Gas Trimmer: Best for gas and reach under shrubs
- 22cc 2-cycle engine
- 17-inch straight shaft
- Compatible attachments
- SmartStart system
The straight shaft is designed to reach beneath bushes and obstacles. Its 22cc gas engine and compatible attachment options suit buyers who want a gas-powered tool.
Pros
- Gas powered
- Straight shaft reach beneath bushes
- Compatible with useful attachments
Cons
- 2-cycle engine requires gas and oil handling
- Attachment options may require separate purchases
The Husqvarna 122LK 17-Inch Straight Shaft Gas Trimmer is the gas pick for reaching beneath bushes and changing tools with compatible attachments. Husqvarna describes its 22cc two-cycle engine as suited to occasional homeowner use and includes a SmartStart system intended to make starting easier.
The straight shaft is designed to reach beneath bushes and other obstacles. Husqvarna also says the model works with its T25 head and a variety of attachments that click on for tool changes.
This option makes sense if you prefer a gas engine and want an attachment-capable shaft. It requires fuel handling and engine care, unlike the battery-powered options above.
The listed cutting width is 19.7 inches, despite the model name's 17-inch wording. Check the exact model details and attachment compatibility before choosing it.
What should you compare before choosing a straight shaft trimmer?
Compare shaft reach, total weight, power source, and how the line advances before focusing on cutting width. Those factors shape how the tool feels through a full trimming session.
A telescopic shaft, like the EGO models, lets you adjust working length. Fixed straight shafts can still reach beneath bushes, but your height and arm position affect comfort.
Weight matters most when your yard has long fence lines or many obstacles. The stated weights here range from 7.5 lb for the EGO ST1623T to 18.7 lb for the Greenworks 60V, though included battery configurations may differ.
Line systems also vary: EGO's POWERLOAD winds line with a button, the Greenworks 60V uses Load N’ Go, and the Ryobi and Greenworks 80V models use bump-feed heads. If line breaks often, our guide to trimmer line breaking covers common causes and fixes.
Is a battery or gas straight shaft trimmer right for you?
A battery trimmer suits you if you want to avoid gas handling and can work within a battery platform's runtime. A gas option may fit if you want an engine-powered tool and are willing to maintain it.
Battery kits differ in what they include, so check whether the kit has a battery and charger. The Milwaukee is a bare tool, while several EGO and Greenworks choices include both.
The Husqvarna 122LK is the gas option here, with a 22cc two-cycle engine and SmartStart system. Follow its manual for fuel, starting, and maintenance instructions.
When are attachment-capable trimmers useful?
Attachment-capable trimmers make sense when you plan to use compatible tools such as an edger, hedge trimmer, or pole saw. They can reduce the number of separate powerheads you need, though compatibility is brand and system specific.
The Greenworks 60V and 40V, Ryobi 40V, Milwaukee QUIK-LOK, and Husqvarna 122LK list attachment support. Check the exact attachment system and the attachments you want before buying, since similar shaft designs do not guarantee compatibility.
For a broader shortlist, read our best string trimmers with attachments. If you only need trimming and edging, compare the value of a separate tool with an attachment setup.
Which straight shaft string trimmer should you choose?
Choose the EGO ST1623T if adjustable shaft length and automatic line feed are your priorities. Pick the Greenworks 60V or Milwaukee if a compatible attachment system matters, the Ryobi if adjustable cutting width is useful, and the Husqvarna if you want gas power.
The right best straight shaft string trimmer is the one whose weight, line system, and power source fit your yard and routine. For a final check, revisit the string trimmer buying guide and compare weight, power, and line before deciding.

Frequently asked questions
What is a straight shaft string trimmer good for?
A straight shaft trimmer can reach beneath shrubs, fences, and other obstacles, and its longer shape often suits taller users. The right choice still depends on its weight, balance, power source, and how you trim.
Compare shaft shape with your yard and handling needs in our straight shaft vs curved shaft guide.
Are straight shaft trimmers better?
Straight shaft trimmers can offer more reach beneath bushes and around obstacles. A curved shaft may feel easier to maneuver for some users, so neither shape is best for every yard.
Consider your height, trimming route, and tool weight before choosing.
Can a straight shaft trimmer use attachments?
Some can, but attachment systems differ by brand and model. The Greenworks 60V, Greenworks 40V, Ryobi 40V, Milwaukee QUIK-LOK, and Husqvarna 122LK options here support compatible attachments.
Confirm that an attachment is approved for the exact trimmer before buying it.
Should I choose a gas or battery straight shaft trimmer?
Choose a battery model if you want cordless trimming without handling gas, and check its battery platform and runtime for your yard. A gas option can suit buyers who prefer an engine-powered tool and accept fuel mixing and engine care.
Our gas vs battery trimmer comparison covers the tradeoffs.
How do I choose the right cutting width?
A wider cutting path covers more ground per pass, while a narrower path can be easier to steer around plants and tight edges. Some models let you adjust the width, such as the Ryobi 40V from 13 to 15 inches.
Use your yard layout and the trimmer's power needs to guide the choice.
