I’ve been using the Worx WG737E in my own garden for a few months now, and overall I’d give it 4 out of 5 stars. Here’s what’s worked well, and where it’s let me down.
It’s part of Worx’s wider PowerShare battery system, so if you’re thinking about building out a full cordless setup rather than just buying one mower, it’s worth reading alongside my guide to the Worx PowerShare system, which covers hedge trimmers and pole saws too. This review also sits within my broader guide to garden tools and equipment, if you want the bigger picture.
Our Quick Verdict
★★★★☆
A lightweight, easy-to-use cordless mower that suits small to medium UK lawns well, as long as you keep on top of the grass.
I’ve been using the Worx WG737E 40V 37 cm cordless lawn mower in my own garden for a few months now, and it’s proven to be a lightweight, easy-to-handle mower that performs very well on a typical small to medium UK lawn. The 37 cm cutting width is a good middle ground between manoeuvrability and getting the job done quickly, and the PowerShare battery system is a real plus if you already own other Worx tools.
- 37 cm cutting width – suits most small to medium UK gardens
- Lightweight and easy to manoeuvre and store
- Compatible with the Worx PowerShare battery system
- Mulching plug included in the box
- Cuts right to the edge, cutting down on extra trimming
Best for: homeowners who want a simple, reliable cordless mower for regular lawn maintenance without dealing with a cable.

It’s also good value compared with similarly sized cordless mowers, especially given it comes with two batteries. Next to smaller 34 cm models like the Worx WG779E, the extra width makes a noticeable difference on medium lawns.

Who it’s best for
- Small to medium UK gardens — the 37 cm width balances manoeuvrability with decent coverage
- Homes with limited shed or garage space — the foldable handle stores easily
- Families sharing garden jobs — light enough for most people to handle comfortably
- Anyone already on Worx PowerShare — the batteries work across a lot of their range
If you’re regularly cutting a very large lawn, or long wet grass, I’d look at a wider cordless mower (40–46 cm) or petrol instead — this one won’t be the fastest option for that.
What I like
Lightweight and easy to use
It’s light enough that even teenagers can handle it safely — not intimidating at all, which makes it easy to share mowing duties around the family. No cable means nothing to trip over or slice through.
Like most cordless mowers it’s got a two-step start and stops the blade the moment you let go of the handle. Combined with no trailing cable, it feels predictable — good if you’ve got a less experienced family member helping out.
Compact Storage
The handle folds down flat and doesn’t eat much shed space. Genuinely useful if you’re tight on room.
Clean Cutting to the Edges
The cut-to-edge design does exactly what it says — you can mow right up to a border and skip the strimming pass afterwards.
Mulching Plug Included
Some brands charge extra for this; Worx just gives it to you in the box. On a dry day with grass at a sensible length, it does a genuinely good job recycling clippings back into the lawn.
Grass Collection Box
40L hybrid bag, solid plastic top with breathable mesh sides. In UK conditions this combination works well — the mesh lets damp grass pack in properly without the whole thing turning into mush, and the solid top keeps dust off you on drier days.
Cutting Height Settings
The Worx WG737E offers six cutting height positions, ranging from roughly 20mm to 70mm, adjusted via a single central height lever.
I mostly stick to Position 3 (around 40mm) — a tidy finish for a normal family lawn without stressing the grass. When I’ve tried the lower settings it’s occasionally torn the grass up and left bare patches behind, so I’d only go that short on a lawn that’s properly level. Mine isn’t perfectly flat, and cutting too low made it easy to scalp the high spots — a mistake I only made once.
You can go lower, but I’d only recommend the lowest settings on a well-levelled lawn. On uneven or slightly bumpy UK grass, cutting too short makes it easy to scalp high spots — something I’ve learned to avoid.
Below are two images showing a before-and-after cut with the Worx WG737E set to Height 3, which is its middle setting.
The brown patch on the right is from our dog and not a result of the lawn mower — you can even see her photo-bombing at the top of the image!
Worx Intellicut™ Technology Explained
The standout feature on this mower. It automatically ramps up torque when it hits thicker or longer grass, then eases back off in the lighter patches — smoother cut, better battery life, less strain on the motor without you doing anything differently. Instead of running flat out constantly, it only spends extra power when it actually needs to.

Real-World UK Use (Weather, Grass & Reality)
UK grass is rarely bone dry — usually dry on top, damp underneath. The WG737E still cuts cleanly in those conditions, but I’ve noticed grass residue builds up under the deck over time. Every few mows I give it a quick scrape (a wooden spatula does the job) to keep the airflow clear and the Intellicut system working properly.
Skip that step and the mower doesn’t cut worse exactly — it just works harder, which shows up as faster battery drain.
Where It Could Be Better
The mulching system struggles with long, damp grass — it clogs quickly, and that’s when you notice the battery draining faster than usual.
I’ve had it run out of charge before I’d finished a mow. The standard charger takes about four hours, fine if you plan ahead, annoying mid-job. It’s really only happened to me when I’ve let the grass get long and wet, so for most smaller gardens on a normal mowing schedule it shouldn’t be an issue.
💡 Tip: either pick up a spare PowerShare battery so you can swap and keep going, or use one of Worx’s fast chargers, which cuts charge time down to around an hour.
I ended up buying a pair of smaller Worx 20V 2.0Ah PowerShare batteries on eBay, originally for my hedge trimmer (covered in my Worx WG252E review). They’re lighter and easier to handle on the trimmer, but they’re also fully compatible with the mower — so on the rare occasion the bigger 4.0Ah batteries run flat mid-cut, I can swap the smaller ones in and finish the job.
One of the biggest selling points is Worx’s 20V PowerShare battery system. These same batteries slot into a wide range of other garden and DIY tools, meaning you can expand your collection without buying more chargers.
Examples include:
- Worx WG163E Grass Trimmer
- Worx WG801E Shrub & Grass Shear
- Worx WG543E Leaf Blower
- Worx WG583E Hedge Trimmer
- Worx WX355 Cordless Drill
This system saves money, cuts down on clutter, and makes your shed or garage much more efficient.

Maintenance — and why it’s worth doing
Most reviews skip this, but in real UK conditions — damp grass, shed storage, seasonal use — maintenance is what decides how the mower’s still performing in a few years, not just on day one.
It’s low maintenance if you stick to a simple routine. After each mow I spend about two minutes on this:
- Remove the battery and tip the mower safely
- Scrape off any grass buildup under the deck
- Lightly spray the blade and underside with a tool spray (I use Stihl Superclean)
- Leave a thin protective coating before storing it away
That’s really it — it stops moisture and grass residue sitting on bare metal, which is what causes rust in the first place.
Damp grass left under the deck does more damage than people expect. In a typical UK shed you’ve got moisture building up overnight, condensation from temperature swings, and clippings holding water right against the metal. A quick spray breaks down residue, adds a thin protective barrier, and cuts down the chance of surface rust — takes seconds and makes a real difference over a season.
Storage matters more than people think, too — most tools wear out from sitting badly, not from use. Where you can, keep the mower off the ground, away from damp shed walls, and give it a minute to dry before you put it away.
The whole routine boils down to: clean, dry, protect, store. It’s a small habit, but it’s kept mine free of the surface rust I’ve seen turn up on other tools after one wet winter.

Final Verdict
I’d recommend the Worx WG737E if you want a mower that’s light, safe, and well suited to regular lawn care on a small to medium UK garden.
Add a spare battery and it becomes a genuinely low-maintenance, reliable option — especially if you’re already using Worx PowerShare tools elsewhere. If you’re still weighing up options, my Best Cordless Lawn Mowers UK guide covers top picks across different garden sizes and budgets.

❓ Worx WG737E Review – Frequently Asked Questions
Is the Worx WG737E suitable for small UK gardens?
Yes. Mine’s on the smaller side and it handles it easily — I’d say it’s comfortable up to around 500m². Past that it’s not that it can’t cope, it just starts taking a while.
How long does the battery last?
It varies more than I expected. On dry, recently-mown grass I can get close to 35 minutes out of a battery; on longer or damp grass it’s closer to 20–25, because the Intellicut system is working harder and pulling more power to compensate.
Can it mow damp grass?
It’ll do it, but the mulcher is the weak point — it clogs up fast once the grass has any real moisture in it. If I know it’s been raining, I either wait a day or take the mulching plug out and collect instead.
What’s the difference between the WG737E and WG779E?
Mainly the deck — 37cm versus 34cm. Doesn’t sound like much on paper, but on a medium lawn that extra width means noticeably fewer passes to get the job done.
Does Intellicut actually make a difference, or is it just marketing?
It’s real, not just a spec-sheet feature. You can hear it — the motor audibly picks up when it hits a thicker patch and drops back down once it’s through. It’s part of why the battery lasts as long as it does; it’s not running flat out the whole time.
