Greenworks 40V Cordless Brushcutter (GD40BCB) with Harness, 40cm Cutting Width – Tool Only

What this brushcutter is for

If you’ve got grassy edges, tougher weeds, and the occasional “we should really sort this out” patch around a larger garden, the Greenworks 40V cordless brushcutter is built around versatility. Over the base, it’s designed to work as either a grass trimmer (dual 2mm nylon line) or a brushcutter using a blade—so you’re not constantly swapping tools. It’s also meant to feel more controlled than a basic handheld trimmer thanks to the included harness and adjustable bike handle.

That said, it’s not a full kit in the usual sense. This is a “tool only” package, supplied without a battery or charger. If you don’t already own a Greenworks 40V battery, you’ll need to factor that into your decision.

Key features worth paying attention to

A big part of the appeal is the two-in-one approach. On paper, the dual line trimmer setup is for long grass and general trimming, while the unit can switch to a blade to tackle weeds more aggressively. The line head uses bump feed, which is a practical way to extend nylon line by tapping the cutting head against the ground while you’re working. It’s the kind of feature that keeps you from stopping every few minutes to manually reload line.

You also get comfort and control features that make a noticeable difference during longer sessions. The harness helps take some of the strain off your arms, and the adjustable bike handle is there to help you find a workable posture.

What it feels like in everyday use (practical examples)

Imagine you’re cleaning up the perimeter of a driveway: first you run it with the 2mm nylon line to tidy up grass and lighter weeds along the edge. Once you hit the thicker patches—say around a fence line where weeds grow more stubbornly—you can switch to the blade approach without turning the whole job into a workshop activity.

Then, when you’re using the nylon line and it starts getting short, bump feeding is meant to be quick: tap, carry on, and keep moving. It’s a small thing, but for anyone who’s had a trimmer that becomes annoying halfway through, that convenience is usually what people remember.

The essentials (specs that affect buying decisions)

The cutting width is listed as 40cm, and the trimming mode uses a 2mm nylon line with a bump feed system (2mm line or a blade listed as 25cm). The motor is described as brushless, and the power platform is Greenworks 40V.

Where it shines, and where it may fall short

This model makes sense if you want one cordless unit that can handle both grass edging and weed cutting, and you’ll appreciate having a harness and adjustable handle to keep it comfortable during longer sessions.

But there are limitations to be realistic about. Because it’s tool-only, the overall value depends heavily on whether you already have a compatible Greenworks 40V battery. If you don’t, the “missing” battery and charger can quickly change the cost picture.

Also, while it’s positioned as “strong” and well balanced for power and run times (with brushless design), cordless brushcutters can still be sensitive to how heavy the growth is and how long you keep pushing without breaks. If you expect consistently brutal, thick brush for hours on end, you may find you need to manage workload rather than expecting it to run indefinitely.

What to check before you buy

Start with the battery situation. The package is explicitly without a battery and charger, and it’s stated to work with Greenworks 40V 2Ah or 4Ah batteries—so check what you already own. Next, think about the cut you’re planning: if your garden is mostly grass trimming with occasional weeds, the nylon line approach will likely cover most of your work. If you regularly deal with tougher weeds, you’ll want to make sure the blade mode suits your expectations.

Finally, consider your comfort needs. The harness and bike handle are included for a reason, if you’re sensitive to arm strain or you do regular edging jobs, this kit leans more towards convenience than a basic handheld trimmer.

Buying verdict

It’s worth considering if you already have (or plan to buy) Greenworks 40V 2Ah or 4Ah batteries and you want a 40cm cordless brushcutter that can switch between dual 2mm nylon line trimming and blade use, with a harness and adjustable bike handle for better control.

You may want to skip it if you don’t own a compatible Greenworks 40V battery, because you’ll likely have to purchase one separately to make the tool usable. It may also not suit you if your main goal is light, occasional tidying where a simpler trimmer setup would be enough—because the extra “brushcutter” capability and harness approach might be more than you need.
