Greenworks 40V Cordless String Trimmer 16" — Tool Only, Brushless Motor & Dual-Line Head

Greenworks 40V 16-Inch Cordless String Trimmer (Tool Only) is a brushless, battery-powered trimmer that offers quiet, lightweight trimming and accepts multiple Greenworks attachments for expanded yard tasks.

Designed for homeowners who want gas-free performance without sacrificing power, this 16" trimmer uses the Greenworks 40V battery platform and a brushless motor to deliver reliable torque, reduced noise, and longer motor life. The tool-only configuration lets you use existing Greenworks 40V batteries or choose the battery size that fits your lawn. Its compact build and easy-to-reload dual-line head make it practical for edging driveways, tidying flower beds, and maintaining fence lines.

How does this trimmer handle common yard jobs?

The 16-inch cutting diameter and .095" dual-line bump feed head make short work of grass and light weeds around hard-to-reach spots. The trim head reloads quickly, and the brushless motor sustains power under load so you get consistent cutting performance across the yard.

• 16-inch cutting swath for faster passes
• .095" dual-line bump feed for efficient trimming
• Brushless motor maintains torque on thicker growth
• Easy-wind spool reduces downtime when reloading line

What makes the brushless motor and 40V system beneficial?

Brushless technology reduces internal friction and heat, which improves runtime and extends the tool's useful life compared with brushed designs. The 40V platform gives access to over 75 compatible Greenworks tools, so one battery family can power many lawn and garden tasks.

• Brushless design for longer motor life and quieter operation
• 40V battery compatibility across Greenworks tools
• Instant electric start with no mixing or pull cords
• No gasoline, oil, or exhaust emissions to manage

Can this trimmer expand into other yard tools?

Yes — the trimmer is attachment capable, letting you add specialized tool heads to cover other chores without buying separate full-size tools. Interchangeable attachments transform the unit into an edger, hedge trimmer, pole saw, cultivator, or blower for more versatility in one platform.

• Compatible with PAC458 edger for clean borders
• PAC459 hedge attachment for light shrub work
• PAC460 polesaw for pruning higher branches
• PAC461 cultivator and PAC462 blower for soil and debris tasks

How comfortable and easy is it to use for regular maintenance?

The trimmer is engineered to be lighter and more maneuverable than many gas models, reducing fatigue during longer jobs. Two-speed selection and a variable trigger let you dial in control for delicate edging or faster cutting, and the straightforward bump-feed head keeps line changes simple.

• Compact, lightweight body for improved handling
• 2-speed settings plus variable trigger for precise control
• Approximately 25% lighter than comparable gas trimmers
• Virtually maintenance-free operation — no oil or fuel upkeep

Who is this for? Homeowners with small to medium yards, landscape hobbyists, or anyone already invested in the Greenworks 40V battery system will find this trimmer a practical, low-maintenance option. It suits users who want quieter, cleaner operation than gas tools and the flexibility to add attachments later. If you need a straightforward, durable trimmer that pairs with a multi-tool battery platform, this Greenworks 40V 16" model is a good fit.
