Greenworks 40V TorqDrive 15" String Trimmer — 15-inch Cutting Swath, .080" Dual-Line, Lightweight

The Greenworks 40V 15-inch TorqDrive String Trimmer is a cordless, lightweight yard tool built to cut through dense grass and weeds with up to 30% more torque while running on a 40V battery (battery and charger sold separately).

Designed for homeowners and garden enthusiasts who want gas-like power without the fumes or maintenance, this 15" trimmer combines an efficient dual-line bump-feed head with an adjustable speed trigger and a two-speed selector. Its TorqDrive transmission boosts torque for tougher cutting tasks, while the low weight and ergonomic handle reduce fatigue during longer trimming sessions. Because it’s battery-powered, it starts instantly, runs quietly, and eliminates the need for oil or gasoline.

How does this trimmer handle thick grass and stubborn weeds?

The TorqDrive gearing delivers more low-end torque, so the trimmer slices through heavy, overgrown patches without bogging down. Pairing that torque with the .080" dual-line bump-feed head gives you consistent cutting performance and quick line advancement when you need it.

• TorqDrive increases torque by roughly 30% for tougher cutting.
• 15-inch cutting swath covers more ground per pass.
• .080" dual-line bump feed advances line cleanly under load.
• Two-speed selector balances power and runtime needs.

What controls and settings are available for precise trimming?
