Pros
- Wide 40 cm line cut clears open ground fast
- Open G40 platform shared across 40+ Greenworks tools
- Balanced, comfortable for longer grass sessions
Cons
- Wide cut is less precise around obstacles
- 40V ceiling below the toughest scrub work
- Best value only if you buy into the G40 platform
The Greenworks GD40BC leans on one standout feature: a 40 cm line cutting width, one of the widest in its class. On open grass that translates directly into fewer passes and faster work. It runs on the open G40 battery platform shared across more than 40 Greenworks tools.
Who it’s for
Medium-to-large lawns and open ground where covering area quickly matters more than pinpoint edging. If you’re already in the Greenworks G40 ecosystem, the value is obvious. For tight, obstacle-heavy gardens the narrower Ryobi is easier to steer.
Verdict
A fast, comfortable cordless brush cutter for open grass, and a strong pick for anyone building out the G40 platform.
A fast, comfortable cordless for open grass thanks to its wide 40 cm cut — and a strong pick if you're building out the G40 platform.
