Worx WG183E vs Greenworks GD40BC

The Worx WG183E and Greenworks GD40BC both run on roughly 40V of cordless power, but they’re built around different priorities. The Worx chases pure ease of use: it’s about as light as cordless trimmers get, with automatic line feed and batteries already in the box. The Greenworks trades some of that lightness for a wider cutting swath and the option to fit a blade, positioning it as the more capable — if bulkier — machine of the two. Neither is objectively “better”; the right pick depends on how much your garden actually throws at you.

At a glance

Attribute	Worx WG183E	Greenworks GD40BC
Power	40V (2× 20V PowerShare)	40V G40 platform
Weight	2.2 kg (excl. battery)	Heavier — bulkier build
Cutting width	33 cm (line)	≈ 40 cm (line)
Cutting head	Line only, AutoFeed	Line head + blade included
Battery supplied	2× 2 Ah + charger	4 Ah + charger
Ecosystem	Worx PowerShare 20V/40V	Greenworks G40 (40+ tools)
Best suited to	Light, quick lawn edging	Wider lawns, occasional light scrub

Clear wins: the WG183E wins on weight and sheer simplicity for grass-only work; the GD40BC wins on cutting width and versatility thanks to its included blade attachment.

Weight and everyday handling

This is the Worx’s headline advantage. At 2.2 kg excluding battery, the WG183E is genuinely one of the lightest cordless trimmers on the market — the kind of weight that makes a difference on a long session of edging around beds, fences, and paths. The Greenworks GD40BC is a noticeably heavier, more substantial tool. It’s not tiring to use for typical garden sessions, but it doesn’t disappear in your hands the way the Worx does. If arm fatigue or a smaller-framed user is a real consideration, that weight gap matters more than any spec sheet number.

Cutting width and coverage

The GD40BC pulls ahead here. Its roughly 40 cm line cutting width is well above the WG183E’s 33 cm, and on anything beyond a small garden that difference adds up — fewer passes across a lawn, less time spent walking back and forth. The Worx’s narrower head is no obstacle for typical edging and small-to-medium plots, but if you’re regularly covering a larger open area, the Greenworks’ wider swath will get the job done faster.

Line-only versus blade-capable

This is the clearest functional split between the two. The Worx WG183E is strictly a line trimmer, with AutoFeed automatically advancing the line as it wears — convenient, but there’s no blade option at all, so it’s confined to grass and light growth. The Greenworks GD40BC ships with both a line head and a blade attachment, which lets it tackle denser grass and light woody stems the Worx simply can’t touch. Neither is a true brush-clearing machine for established brambles or scrub — for that, a dedicated blade-first cordless or petrol brush cutter is the safer choice either way.

What’s in the box

Both machines are ready to run out of the box, which is worth noting since plenty of cordless trimmers are sold bare. The WG183E includes two 20V PowerShare batteries (combining for 40V) plus a charger. The GD40BC includes a single 4 Ah battery on the G40 platform, also with a charger. Neither requires an immediate extra purchase to get started, though buying spare batteries later works out differently depending on which ecosystem you’re in.

Motor and durability

The WG183E uses a brushed motor, which is a sensible match for its price point and light-duty grass focus, but it won’t match the longevity of a brushless design under sustained heavier use. Greenworks doesn’t push the GD40BC as a premium brushless flagship either, but its bulkier build and blade compatibility suggest a tool meant to handle a bit more abuse over time. If you expect to lean on the blade attachment regularly, that sturdier build counts for something.

Battery ecosystem

Worx’s PowerShare platform spans a wide range of 20V and 40V tools, so the two batteries included with the WG183E can double up on other Worx garden and DIY tools later. Greenworks’ G40 platform is similarly broad, shared across more than 40 tools, and the GD40BC’s 4 Ah pack is a reasonable starting point if you’re planning to expand into mowers, blowers, or other G40 kit down the line. Neither ecosystem is a wrong choice — it comes down to which brand’s other tools you’re more likely to want.

Choose the Worx WG183E if…

• You want the lightest possible trimmer for easy, fatigue-free lawn edging
• Your garden is strictly grass, with no brambles or woody growth to deal with
• You’d rather keep things simple with a line-only head and AutoFeed

Choose the Greenworks GD40BC if…

• You want a wider 40 cm cut to clear a bigger lawn faster
• You occasionally need to tackle light scrub and want a blade option included
• You don’t mind a heavier tool in exchange for more versatility

Which should you buy?

If your priority is comfort and simplicity on a small-to-medium lawn that’s genuinely just grass, the Worx WG183E is hard to beat — it’s light, ready to use out of the box, and the AutoFeed line takes one more chore off your hands. If you’re working a larger or more open plot, or you occasionally run into growth thick enough that a blade would help, the Greenworks GD40BC’s wider cut and included blade attachment make it the more capable all-rounder, at the cost of some extra weight. Neither machine is built for serious brush clearing — for that, look at a dedicated blade-first cordless or petrol brush cutter instead.
