Quick verdict
If you want the most cutting power in Greenworks' lineup here, the 60V 16-inch brushless trimmer is my starting pick. Greenworks positions its brushless motor at 26cc gas-equivalent power, and it ships with a 2.5Ah battery and charger plus a spin-to-load head for quick reloading. That combination suits larger or tougher yards.
Greenworks 40V 12
This 40V BST4000 is a light 12-inch trimmer with a 0.065-inch auto-feed head and a variable-speed trigger, sold as a bare tool. It runs on Greenworks G-MAX 40V batteries, so it is a sensible pick if you already own that platform and want to add a trimmer cheaply.
The best Greenworks string trimmer picks compared, across 24V, 40V, and 60V, with honest notes on cut width, battery inclusion, and reload style.
Why you should trust this guide
I built this Greenworks guide by reading each listing and mapping out how the 24V, 40V, and 60V platforms differ, because that voltage choice shapes everything from power to weight. Greenworks spreads its trimmers across these battery families, so I focused on which platform a tool uses, how wide it cuts, whether it edges, and whether a battery is included.
I have kept the notes honest. These are battery trimmers sized for grass and weeds rather than heavy brush, and I say so plainly. Where a tool is a bare unit without a battery, I flag it because that changes the real cost. Where runtime figures come from Greenworks, I present them as the maker’s ratings. The aim is to help you match the right Greenworks trimmer to your yard.
How we evaluated
My evaluation focused on the criteria that separate these Greenworks trimmers. First is the battery platform, since 24V is lightest, 40V is the flexible middle ground shared across many tools, and 60V delivers the most power. Second is cutting width and reload style, from 12-inch auto-feed heads to a 16-inch spin-to-load head, which affect speed and convenience.
I also weighed weight, edging ability, and whether a battery and charger are included. Runtime and power-equivalent figures are taken from Greenworks rather than measured by me. I did not run these trimmers in a yard; I compared the published specifications, included accessories, and stated intended use of each model to keep the comparison grounded.
What to look for
- Battery platform: 24V is lightest for small yards, 40V balances weight and power, and 60V delivers the most cutting force.
- Cutting width: A 12-inch head suits tidy lawns, while a 16-inch head clears larger or overgrown areas faster.
- Kit or bare tool: Most kits include a battery and charger, while the BST4000 is a bare tool needing G-MAX 40V packs.
- Reload style: Spin-to-load and auto-feed heads reduce the fuss of advancing line.
- Edging ability: Pivoting heads and edging guides let one tool trim and edge cleanly.
- Weight and fit: Lighter tools and telescoping shafts reduce fatigue and suit a range of user heights.
- Warranty: Several Greenworks trimmers carry multi-year tool and battery warranties worth factoring in.
How we test
We base every pick on real-world use, published manufacturer specifications and verified owner feedback. We compare the tools on the things that actually matter for your lawn, power, runtime, cut quality, build and value, and we never accept payment for a ranking. When we have not used a specific model first-hand, we say so.

What to look for
Which voltage fits your yard
A 24V trimmer is lightest for small lawns, a 40V tool balances power and weight for most yards, and a 60V model brings the most force for tougher, overgrown areas.
Kit versus bare tool
Most of these Greenworks trimmers include a battery and charger, but the BST4000 is a bare tool, so it only makes sense if you already own G-MAX 40V packs.
Cut width and reload
A 12-inch auto-feed head suits routine trimming, while the 60V 16-inch spin-to-load head clears more ground per pass and reloads quickly.
Edging versus trimming
Several models convert to an edger with a pivoting head and guide, so choose one of those if you want clean lines along walks and beds.
Weight and comfort
The 24V model is the lightest at around 6 pounds, while the 60V unit is heavier, so weigh comfort against the extra power you gain.
Our verdict
If you want the most cutting power in Greenworks' lineup here, the 60V 16-inch brushless trimmer is my starting pick. Greenworks positions its brushless motor at 26cc gas-equivalent power, and it ships with a 2.5Ah battery and charger plus a spin-to-load head for quick reloading. That combination suits larger or tougher yards.
FAQs
For small yards, the lightweight 24V trimmer is easiest. For most yards, 40V balances power and weight, and for larger or overgrown areas, the 60V model offers the most cutting power.
Most here do, shipping with a battery and charger. The 40V BST4000 is a bare tool, so you need compatible Greenworks G-MAX 40V batteries to run it.
Yes. Several models, including the 40V 2-in-1 and the 24V trimmer, convert to an edger with a pivoting head, and some include a steel edging guide for clean lines.
They range from a 12-inch cut on the smaller models to a 16-inch swath on the 60V trimmer. A wider swath clears open ground faster, while a narrower head is easier in tight spots.
Within a voltage family, yes. A 40V battery works across Greenworks 40V tools, and the same applies to the 24V and 60V lines, so one platform can power multiple pieces of equipment.
