One of the reasons I chose the WG737E is that it offers very good value compared with many similarly sized cordless mowers, especially considering the two batteries included. Compared with smaller 34 cm models like the Worx WG779E, the WG737E’s 37 cm cutting width also makes mowing medium-sized lawns noticeably quicker.

Who the Worx WG737E Is Best For
After several months of using the Worx WG737E 40V 37cm cordless lawn mower in a typical UK garden, it’s clear this model suits certain lawns particularly well.
• Small to medium UK gardens – the 37 cm cutting width balances manoeuvrability with decent coverage.
• Homes with limited shed or garage space – the foldable handle makes it easy to store.
• Families sharing garden jobs – the lightweight design means most people can handle it comfortably.
• People already using Worx PowerShare tools – the batteries work across many Worx garden and DIY tools.
However, this mower may not be the best option if you regularly cut very large lawns or long, wet grass. In those situations, a wider cordless mower (around 40–46 cm) or a petrol mower will usually finish the job faster.
What I Like – Worx WG737E Review
Lightweight & Easy to Use
The Worx WG737E cordless lawnmower is light enough that even teenagers can handle it safely. It doesn’t feel intimidating or heavy, which makes it perfect if you’re sharing garden duties with the family.
Being cordless means there’s no cable to trip over or slice through, making mowing less stressful.
Like most modern cordless mowers, the WG737E uses a two-step start system and stops the blade instantly when you release the handle. Combined with the lack of a trailing power cable, it feels predictable and easy to control — especially useful when less experienced users are helping with mowing.
Compact Storage
The handle folds down neatly, and it doesn’t take up much room in the shed. A great option if space is limited.
Clean Cutting to the Edges
The cut-to-edge design is genuinely useful—you can mow right up to the borders, reducing the need for strimming afterwards.
Mulching Plug Included
Some brands charge extra, but Worx includes the mulching plug in the box. On a dry day with grass at a sensible length, it works beautifully, recycling clippings back into the lawn as natural fertiliser.
Grass Collection Box
The WG737E comes with a 40L hybrid grass collection bag, with a solid plastic top and breathable mesh sides. In practice, this works well in UK conditions — the mesh allows airflow so damp grass packs in properly, while the solid top helps keep dust and debris from blowing back when mowing in drier weather.
Cutting Height Settings
The Worx WG737E offers six cutting height positions, ranging from roughly 20mm to 70mm, adjusted via a single central height lever.
In practice, I usually stick to Position 3 (around 40mm), which gives a healthy, tidy finish for a typical family lawn without stressing the grass. It’s a good all-round height if you’re mowing regularly. When I’ve tried the lower settings, it has sometimes ripped up the grass slightly and left barer patches behind.
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
One of the standout features of the Worx WG737E cordless lawn mower is its Intellicut™ system. This clever technology automatically increases torque when the mower reaches thicker or longer grass, then eases off again once it returns to lighter areas. The result is a smoother cut, better battery efficiency, and less effort for you. Instead of running at maximum power all the time, the mower only uses extra energy when it’s really needed. The short video below demonstrates Intellicut™ in action — notice how the WG737E revs up as it tackles tougher patches and then settles back to conserve power.

Real-World UK Use (Weather, Grass & Reality)
Let’s be realistic — UK grass is rarely bone dry. Most of the time it’s mostly dry on top and slightly damp underneath.
In these conditions, the WG737E still cuts cleanly, but I’ve found that grass residue slowly builds up under the plastic deck. Every few mows, a quick scrape (I use a wooden spatula) restores airflow and keeps the Intellicut system working efficiently.
Skip this, and the mower works harder than it needs to — which you’ll notice as faster battery drain rather than poorer cutting.
Where It Could Be Better
As I’ve found during this Worx WG737E review, the mulching system struggles with long, damp grass. It clogs quickly, and that’s when the battery drain becomes obvious.
On one occasion, I couldn’t finish mowing before the batteries ran out. Recharging takes around four hours with the standard charger, which is fine if you plan ahead but frustrating mid-job. For smaller gardens this won’t usually be a problem, and it’s only happened to me when I’ve let the grass get long and wet.
In practice, this mower works best when you’re keeping on top of your lawn. If the grass gets long or stays damp for a few days (which is common in the UK), you’ll start to notice its limits — particularly with mulching and battery life.
💡 Tip: You can either buy extra PowerShare batteries so you can swap and keep mowing without downtime, or use one of Worx’s fast chargers, which can reduce charge time to around an hour.
Personally, I bought a pair of smaller Worx 20V 2.0Ah PowerShare batteries on ebay for my hedge trimmer (which I talk about in my Worx WG252E review). These lighter batteries make the trimmer much easier to handle, while still being fully compatible with the lawn mower. On the rare occasion the larger 4.0Ah batteries run out during a long or wet cut, I can swap the smaller packs 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.

How to maintain the Worx WG737E (and why it matters)
Most cordless mower reviews skip this, but in real UK conditions—damp grass, sheds, and seasonal use—maintenance is what determines how well a mower performs after a few years.
The good news is that the Worx WG737E is very low maintenance if you follow a simple routine.
⚡ 2-minute post-mow routine
After each mow, I spend about 2 minutes doing the following:
- 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
This prevents moisture and grass residue sitting on the metal, which is the main cause of rust.
🛢️ Why a quick spray makes a difference
It’s easy to underestimate how much damage comes from leaving damp grass under the deck.
In a typical UK shed:
- Moisture builds up overnight
- Temperature swings cause condensation
- Grass clippings hold water against metal surfaces
A quick spray helps to:
- Break down residue
- Add a light protective barrier
- Reduce the chance of surface rust forming
It takes seconds, but makes a noticeable difference over time.
🌧️ Storage matters more than you think
Most tools don’t wear out from use—they degrade in storage.
If possible:
- Store the mower off the ground
- Avoid pushing it tight against damp shed walls
- Let it dry briefly before putting it away
Even small changes here can extend the life of the deck and blade.
🧠 The simple rule I follow
Clean → Dry → Protect → Store
It’s a small habit, but it keeps the mower running well and avoids the kind of surface rust that can show up after just one winter.
