The Greenworks 80V brushless string trimmer cuts a 16-inch swath using a dual-line .080-inch bump feed head, powered by an 80V 2.0Ah battery that rapid charges in 30 minutes. The brushless motor sits directly at the cutting head rather than at the handle end, which improves balance and extends battery efficiency.
It suits homeowners and small farm operators managing suburban lots, orchards, and field edges who want gas-comparable cutting power without fuel storage or engine maintenance. The 80V battery platform is specific to Greenworks 80V tools and does not cross over to other Greenworks voltage lines.

Cutting Overgrown Grass, Orchard Edges, and Suburban Lots Where Gas Power Was the Previous Standard
If you've been running a gas trimmer and are evaluating whether an 80V cordless unit can match it for real-world work, the Greenworks 80V sits at the upper end of what cordless residential trimming equipment delivers.
The .080-inch factory line handles standard grass and moderate weeds effectively, and users who have loaded .095-inch line report a meaningful increase in cutting aggression through denser material, though .095-inch is not the manufacturer-recommended diameter and line feeding on the smaller spool requires trimming line length carefully before restarting.
At 16 inches of cutting width, a quarter-acre property including 200 feet of edging is achievable on a single charge for users working at variable speed rather than continuous full throttle.
The 30-minute recharge time makes a two-battery rotation practical for larger or more demanding sessions, and the 80V battery is shared across Greenworks' 80V blower and chainsaw lineup, which reduces the cost of building out a cordless tool set on this platform.
What to Expect from the Greenworks 80V 16-Inch Trimmer in Real Use
Users coming from entry-level gas trimmers report the 80V matches or exceeds cutting power on comparable line diameters. On standard residential lawns including edging work, a single charge covers the full job with battery remaining.
On orchard and farm field applications with tall two-foot grass and heavy weed growth, runtime lands around one hour before requiring a recharge. Power output holds steady until the battery is depleted rather than tapering as charge drops.
The bump feed head works reliably during use. Reloading the spool does have a learning curve: line must be folded at the midpoint and wound clockwise from the center notch, and if the free ends are left too long after reloading, the motor may cut out when the excess contacts the blade guard at startup. Carrying a pair of snips to trim the line before restarting resolves this quickly.
The unit is not split-shaft compatible. The motor-at-head design improves balance but eliminates attachment interchangeability. A shoulder strap is recommended for extended sessions and is available separately.

Frequently Asked Questions
Can you use .095-inch trimmer line in the Greenworks 80V instead of the factory .080-inch?
The manufacturer specifies .080-inch as the recommended line diameter for this trimmer. Users who have loaded .095-inch line report noticeably stronger cutting performance through dense and heavy material, including blackberries and thick weeds.
The smaller spool size compared to commercial gas trimmers means .095-inch line requires careful manual trimming of the free ends after loading to avoid triggering the motor's overload cutout at startup. If you go to a heavier line, carry snips and trim the line flush before restarting after a bump-feed advance.
Is the Greenworks 80V battery compatible with other Greenworks tools?
The 80V battery works across Greenworks' 80V tool platform, which includes the 80V blower, chainsaw, and pressure washer, among others. It is not compatible with Greenworks tools on other voltage platforms such as 40V or 60V.
If you're building out a cordless tool collection, staying within the 80V Greenworks lineup allows one battery and charger to serve multiple tools, and the 30-minute rapid charge makes rotating a single battery between tools practical for most residential sessions.
Does the Greenworks 80V trimmer work with split-shaft brush cutter or edger attachments?
No. This model has a fixed straight shaft with the motor mounted directly at the cutting head, which is not split-shaft compatible. The head-mounted motor design improves weight balance and battery efficiency, but it means the lower shaft cannot be detached for use with brush cutter blades, edger attachments, or other split-shaft accessories.
If you need attachment compatibility, Greenworks makes a separate split-shaft model. Confirm split-shaft compatibility by model number before purchasing any trimmer plus attachment combination.
