Greenworks 40V 17 in Cordless String Trimmer — 5.0Ah Battery, Brushless Motor & 6A Rapid Charger

The Greenworks 40V 17-inch cordless string trimmer with a 5.0Ah rapid-charge battery delivers brushless torque to cut thick weeds and wet grass while remaining lightweight and easy to maneuver.

Compact but powerful, this 40V trimmer pairs a high-efficiency brushless motor with a 0.105" dual-line bump-feed head to handle dense overgrowth without bogging down. The included 5.0Ah battery and 6A rapid charger refill in about 50 minutes so you spend more time working and less time waiting. At roughly 7 lbs (tool only), the design emphasizes user comfort and control for edging, trimming under low-clearance areas, and routine yard maintenance.

How much cutting power does the brushless motor provide?

The brushless motor delivers higher torque and efficiency than comparable brushed designs, helping the trimmer power through wet grass, woody stems, and thick weeds with fewer stalls. Variable speed control lets you dial in power for heavy jobs or extend runtime for lighter trimming.

• 0.105" dual-line bump-feed head for faster material removal
• Brushless motor gives up to 25% more torque versus brushed models
• Variable-speed trigger balances power and battery life

How fast will the battery recharge and how long does it run?

The included 5.0Ah battery recharges in roughly 50 minutes using the 6A rapid charger, making it practical to top up during a lunch break between jobs. Runtime varies with workload and speed setting: moderate trimming will last longer, while continuous heavy cutting reduces runtime accordingly.

• 5.0Ah capacity for extended work periods
• 6A rapid charger restores charge in about 50 minutes
• Swappable 40V battery works across 75+ compatible Greenworks tools

Is the trimmer easy to maintain and reload on the job?

Yes — the quick-change Load-N-Go trimmer head lets you replace or reload line without tools to minimize downtime. The bump-feed head design keeps operation simple while the brushless motor reduces routine maintenance compared with gas alternatives.

• Tool-free line changes speed refills in the field
• Bump-feed mechanism for quick line advancement
• No spark plugs, carburetors, or exhaust maintenance like gas models

How does the trimmer compare to gas models for everyday use?

This cordless unit is about 30% lighter than many gas trimmers, improving control and reducing user fatigue for longer sessions. It also eliminates exhaust fumes and simplifies start-up — just attach a charged battery and go — while delivering comparable cutting performance for most residential and light commercial tasks.

• Approximately 7 lbs bare tool weight for easier handling
• Zero exhaust for cleaner operation around gardens and pets
• Instant start with battery versus pull-start gas engines
