How to choose the right one

  1. Check your battery voltage

    Your existing battery platform determines which tools you can buy. This list includes options from 20V up to 80V. If you own Worx 20V batteries, the Worx 15-Inch model fits directly. Makita users have choices across 18V, 36V, and 40V XGT systems. Bosch owners look at the 18V AMPShare compatible unit. Greenworks offers both 40V and 80V options. Match the voltage to your current inventory to avoid buying a second set of batteries. This ensures immediate compatibility and saves you from redundant purchases.

  2. Select the cutting width

    Cutting width defines how much ground you clear per pass. The models here range from 13 to 17 inches. A 13-inch path, like the Makita option, suits tight spaces and narrow edges. Most models offer 15 or 16 inches for balanced coverage. The 17-inch models, such as the RYOBI carbon fiber shaft version, cover the widest area. Choose a wider swath if you have large open lawns. Pick a narrower one for maneuvering around obstacles. The width directly impacts your trimming speed and efficiency.

  3. Evaluate motor type

    Most tools on this list use brushless motors. This design offers better efficiency and longer life than brushed alternatives. The Makita, Bosch, and Greenworks models feature brushless technology. They provide consistent power delivery as the battery drains. Some entries do not specify the motor type in the data provided. If you want maximum runtime and durability, prioritize the brushless options. They handle heavy weeds better and require less maintenance. Check the attributes section to confirm this feature before purchasing.

  4. Consider shaft configuration

    The shaft type affects versatility and handling. Some models feature attachment-capable shafts, like the RYOBI 40V version. This allows you to swap heads for edging or blowing. Others use a carbon fiber shaft, which is lighter and more durable. The Kobalt model offers a standard straight shaft. Straight shafts generally offer better balance for longer trimming sessions. Curved shafts are lighter but less versatile. Decide if you need multi-tool functionality or just a dedicated trimmer.

  5. Review bare weight

    Weight determines how fatiguing the tool is during use. The Worx model weighs 6.62 pounds, making it the lightest option. The Makita 36V and 17-Inch models weigh 19 pounds. Heavier tools require more effort to hold and maneuver. If you have back issues or small yards, choose a lighter unit. The 11 to 12-pound range offers a middle ground. Consider how long you plan to use the tool. Lighter models reduce strain during extended trimming sessions.

  6. Verify attachment capability

    Some tools support additional attachments for yard work. The RYOBI 40V models feature attachment-capable shafts. This lets you add an edger or blower head. The Makita power head also supports tool-less attachments. This expands your toolset without buying new motors. If you want a multi-purpose yard system, look for this feature. It saves money by combining functions into one power source. Check the attributes for attachment compatibility before buying.

Frequently asked questions

Which string trimmer is the lightest on the list?

The Worx 20V 15-Inch Cordless String Trimmer is the lightest option. It weighs only 6.62 pounds. This makes it the easiest tool to maneuver for extended periods. You will find it ideal for quarter-acre yards where frequent lifting is required. Heavier models like the Makita 36V 17-Inch weigh 19 pounds, which demands more physical effort to handle.

What is the widest cutting width available?

The widest cutting width is 17 inches. Two models offer this broad swath: the RYOBI 40V 17-Inch Carbon Fiber String Trimmer and the RYOBI 40V 17-Inch Attachment Capable Trimmer. A wider cut covers more ground per pass. This feature is useful for clearing large areas of weeds or brush efficiently without making as many passes.

Which trimmer has the highest voltage?

The Greenworks 80V 16-Inch Brushless Trimmer Gen 2 has the highest voltage at 80V. This high voltage delivers significant power for tough trimming tasks. It is designed for users who already own compatible 80V batteries. Higher voltage generally translates to more torque and sustained performance when cutting through dense vegetation compared to lower voltage options.

Are there any brushless motor options?

Yes, several models feature brushless motors. These include the Makita 18V Brushless 13-Inch, the DEWALT 60V MAX 15-Inch, and the Bosch 18V 16-Inch. Brushless motors offer better efficiency and longer runtime. They also reduce maintenance needs since there are no brushes to wear out. This technology provides dependable throttle control across various trimming tasks.

Can I use these trimmers with other attachments?

Some models are attachment capable. The RYOBI 40V 15-Inch and 17-Inch models allow you to swap tools. The Makita 18V Brushless Couple Shaft Power Head also supports a tool-less attachment system. This versatility lets you build a multi-tool yard setup. You can switch between trimming, edging, or other tasks using your existing battery platform.

Which trimmer is best for tight spaces?

The Makita 18V Brushless 13-Inch String Trimmer is best for tight spaces. Its 13-inch cutting swath allows for precise maneuverability. The compact design helps you navigate around obstacles like fences and garden beds. This model is ideal if you prioritize control and access over broad coverage area. It runs up to 6,000 RPM for controlled cutting.

Is there a trimmer with an edger conversion feature?

The Bosch 18V 16-Inch Brushless String Trimmer includes an edger conversion feature. This allows you to switch from trimming to edging without buying a separate tool. It combines high motor speed with this dual functionality. However, you should note its 12.7-pound bare weight, which requires more effort to handle during conversion tasks compared to lighter alternatives.

What is the fastest motor speed listed?

The Makita 18V Brushless Couple Shaft Power Head has the fastest speed at 9,700 RPM. This high speed is useful for various attachment tasks beyond just trimming. Other models like the Makita 40V max XGT run up to 6,500 RPM. The Worx 20V model offers flexible cutting width but does not list a specific RPM, focusing instead on its lightweight build.
