Greenworks G40LT vs Worx WG183E

Both of these sit at the accessible end of cordless grass trimming, and neither is trying to be a brush cutter. The Greenworks G40LT and the Worx WG183E are line-only tools built for lawn edges and light grass, so the decision here isn’t about raw cutting power — it’s about weight, what’s in the box, and which battery ecosystem suits you.

Weight and handling

Both machines are designed to be comfortable for long sessions, but they get there slightly differently. The G40LT’s height-adjustable shaft lets taller or shorter users find a natural working angle, which helps avoid stooping on longer edging jobs. The WG183E leans on raw lightness instead — at around 2.2 kg without its battery, it’s one of the lighter cordless trimmers on the market, and that alone can matter more than adjustability if you’re swinging the tool one-handed around borders and fences for half an hour at a time.

Line feed: bump vs AutoFeed

This is a small but real day-to-day difference. The Worx WG183E uses an AutoFeed system that advances the line automatically as it wears, so you never have to stop and tap the head on the ground. The Greenworks G40LT uses a more conventional feed approach, which works fine but asks a little more of the user mid-job. If you find line-tapping annoying, that tips things toward the Worx.

Battery and what’s in the box

Here’s where buyers most often get caught out with either brand: both the G40LT and the WG183E are sometimes sold as a bare tool, with battery and charger offered as a separate kit. That said, WG183E listings more commonly bundle two 20V PowerShare batteries and a charger as standard, which can make it the more grab-and-go option out of the box — but always check the specific listing rather than assuming, since packaging varies.

Ecosystem: which batteries do you already own?

Neither trimmer exists in isolation — both belong to wider cordless ranges. The G40LT runs on Greenworks’ 40V G40 platform, shared with hedge trimmers, blowers and similar tools, so if you’re building out a Greenworks garden kit, buying into that battery family pays off over time. The WG183E instead uses Worx’s 20V PowerShare cells (two of them, combined for 40V), which is one of the most widely stocked cordless systems around and covers a broad range of Worx garden and DIY tools. If you already own batteries from one of these families, that alone can be the deciding factor.

Cutting scope: neither is a brush cutter

It’s worth being clear-eyed about limits here. Both trimmers are strictly line-only — neither has a blade attachment point, so brambles, woody saplings or dense scrub are off the table for both. If your ground regularly throws up anything tougher than grass and light weeds, this comparison doesn’t really apply to you; you’d want a blade-capable brush cutter instead, since forcing either machine into scrub just stalls the line and burns through charge.

Choose the Greenworks G40LT if…

• You want a height-adjustable shaft to suit your own height comfortably
• You’re already invested in — or planning to build — a Greenworks 40V G40 tool kit
• Your garden is medium-sized with mostly light-to-moderate grass
• You don’t mind a manual line-feed system

Choose the Worx WG183E if…

• You want the lightest possible trimmer for long, comfortable sessions
• You’d rather never tap-advance a line head, thanks to AutoFeed
• You want a good chance of batteries and a charger included as standard
• You’re already using — or want to start using — Worx’s 20V PowerShare ecosystem

Which should you buy?

For most people doing plain lawn edging on a small-to-medium plot, the Worx WG183E edges it slightly, mainly on its very light build and AutoFeed convenience, plus a better chance of batteries being bundled in. The Greenworks G40LT is just as capable for the same kind of light grass work, and its height-adjustable shaft and 40V G40 ecosystem make it the more sensible pick if you already own — or plan to own — other Greenworks cordless garden tools. Either way, remember both are line-only: if your garden ever needs a blade, this isn’t the comparison you need.
