Pros
- Wide 40 cm line cut clears open ground fast
- Brushless motor, harness and D-grip handle included
- Line head and 25 cm blade both in the box
Cons
- Wide cut is less precise around obstacles
- 40V ceiling below the toughest scrub work
- Tool-only — battery and charger extra
The Greenworks GD40BC leans on one standout feature: a 40 cm line cutting width, one of the widest you’ll find on a battery machine. On open grass that translates directly into fewer passes and faster work. It runs on Greenworks’ 40V battery system.
What the listing confirms
The Amazon.co.uk listing gives a brushless 40V motor, a 40 cm cut with 2 mm dual line on a bump-feed head, and a 25 cm blade that swaps in for tough weeds. A harness and an adjustable D-grip handle are included, along with a three-year Greenworks guarantee. It’s sold tool-only — you need a Greenworks 40V 2 Ah or 4 Ah battery and charger.
Who it’s for
Medium-to-large lawns and open ground where covering area quickly matters more than pinpoint edging. If you already own Greenworks 40V tools, the value is obvious. For tight, obstacle-heavy gardens the narrower Ryobi is easier to steer, and for edges only, the G40LT is lighter.
Verdict
A fast, comfortable cordless brush cutter for open grass, and a strong pick for anyone building out the Greenworks 40V system.
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.
Greenworks GD40BC — frequently asked questions
How wide does the Greenworks GD40BC cut?
40 cm with its 2 mm dual line, which is wide for a battery machine and clears open grass noticeably faster. With the blade fitted it cuts 25 cm.
What is the G40 platform?
It's Greenworks' 40V battery system: the 2 Ah and 4 Ah 40V batteries fit all of the brand's 40V garden tools, so one set of batteries can run a mower, blower and this brush cutter. They don't fit its 24V or 60V tools.
Is it good for brambles?
It handles tough weeds and light growth with the 25 cm blade fitted. For established bramble thickets, a petrol machine has more reserve — see the best brush cutters for brambles.
