Finding the best brushless string trimmers requires looking at hard specs rather than marketing claims. We compared 15 models ranked by their published listing details. The Makita 36V Brushless Couple Shaft Power Head leads because it offers a versatile base for multiple attachments using existing 18V batteries. This list focuses on motor type, voltage, and cutting width to help you decide which tool fits your yard size and battery ecosystem.

Match voltage and cutting width to your yard size

Your choice depends on yard size and battery ecosystem. Larger properties benefit from higher voltage platforms like the 80V Greenworks or 60V DEWALT for sustained power. Smaller yards suit 18V Makita models with narrower 13-inch cuts. Check the cutting width attribute to ensure the trimmer handles your specific grass density and area efficiently.

How to choose the right one

Match voltage to yard size

Voltage determines the power available for sustained cutting. For large properties, higher voltage platforms like the 80V Greenworks or 60V DEWALT provide the energy needed for thick grass without stalling. Smaller yards often suit 18V models, which are lighter and easier to handle. Check the listed voltage to ensure the tool matches your property's demands and your existing battery investments.

Select cutting width carefully

The cutting width dictates how much grass you clear per pass. Wider heads, such as the 16-inch Greenworks or 20-inch Makita options, cover more ground quickly, ideal for open lawns. Narrower 13-inch models offer better maneuverability around tight borders and obstacles. Choose a width that balances efficiency with the need to navigate your specific landscape features and obstacles.

Check battery capacity for runtime

Battery capacity, measured in Amp-hours (Ah), dictates how long the tool runs on a single charge. Higher capacity batteries, like the 8.0Ah included with the Bosch model, offer extended runtime for large jobs. Lower capacities may suffice for quick touch-ups. If you already own batteries, verify the Ah rating to ensure you have enough power for your typical workload without frequent recharging.

Consider included attachments

Some models bundle additional tools like leaf blowers or edgers to increase versatility. The Greenworks 80V and DEWALT 20V kits include blowers, allowing you to clear debris immediately after trimming. This approach saves space and cost if you need multiple functions. Evaluate whether you need these extra tools or prefer a dedicated trimmer, as bundled kits may add weight and complexity to your setup.

Evaluate drive type needs

Couple shaft systems allow you to attach various tools to a single power head, offering significant versatility. The Makita 36V Couple Shaft models exemplify this, letting you switch between trimmers and other attachments easily. This is ideal for users who want one base for multiple yard tasks. If you need a dedicated, standalone trimmer, a fixed-shaft model may be more straightforward and portable.

Frequently asked questions

Which brushless string trimmer has the widest cutting width?

The Greenworks 80V 16-Inch Brushless Trimmer offers the widest 16-inch cutting width among the listed models. This width allows you to clear more grass and weeds per pass. It also includes an integrated leaf blower, helping you manage debris immediately after trimming. This combination is ideal for users who want to handle both tasks with one battery platform.

What is the lightest brushless string trimmer in this list?

The Makita 36V Brushless String Trimmer 15-Inch weighs only 1 pound. This low weight makes it highly portable and easy to maneuver for extended periods. You can use it for light trimming tasks without feeling fatigued. It pairs well with existing Makita batteries for reliable performance in medium-sized yards.

Which model includes a leaf blower attachment?

Several models include a leaf blower. The Greenworks 80V 16-Inch Brushless Trimmer and the Milwaukee M18 FUEL Brushless String Trimmer both come with this attachment. The DEWALT 20V MAX Brushless String Trimmer also includes a blower. These kits allow you to trim and blow debris using the same battery system.

Which brushless trimmer has the largest battery capacity?

The Bosch 18V 16-Inch Cordless String Trimmer includes an 8.0Ah battery. This large capacity provides extended runtime for large yards. It delivers steady performance for landscapers who need long-lasting power. Other models like the Makita 36V Brushless Trimmer Kit include 5.0Ah batteries, which offer good runtime for moderate use.

Is there a brushless trimmer with automatic speed adjustment?

Yes, the Makita 36V 15" Brushless Trimmer Kit features automatic speed adjustment. This technology manages torque automatically to maintain consistent performance. It is ideal for users who value adjustable speeds and sustained power. The kit includes two 5.0Ah batteries for extended runtime during heavy-duty work.

Which trimmer is best for small yards?

The Makita 13-Inch Brushless String Trimmer is best for small yards. It offers a manageable 13-inch cut width and fits users with existing 18V LXT batteries. It is not ideal for large properties or heavy brush. This compact tool provides solid performance for moderate yards where higher voltage is unnecessary.

What voltage options are available for brushless string trimmers?

You can find brushless trimmers in 18V, 40V, 60V, and 80V options. The Makita and Bosch models use 18V platforms. The Greenworks 40V Combo and 80V models offer higher voltage. The DEWALT FLEXVOLT is a 60V model. Higher voltage platforms provide more power for thick grass and larger properties.
