I’m Mark from EasyLawnMowing and this is my full written review of the Worx WG737E 40V cordless lawnmower. I unboxed, assembled and tested this model on my lawn so I could bring you an honest, hands-on walkthrough: what’s in the box, how easy it is to put together, the specifications that matter in real use, how it performs cutting both regular and very long grass, and the pros/cons I discovered during the test. If you’re considering a cordless mower for a medium to large garden (up to about 1/4 acre), this is the model many people ask me about — here’s everything I learned.
Worx WG737E 40V Video Review
What you get in the box (unboxing)
Right out of the box you get everything you need to mow straight away: the mower itself with folding handles, a 40 L collection bag, two 20V 4.0Ah PowerShare batteries, a dual charger that charges both batteries at once, the mulching plug, and the small parts required for assembly plus user literature. In short: it’s supplied complete — no need to buy batteries or a charger separately.
Key items included:
- Worx WG737E mower with a 16″ (40 cm) cutting deck and mulching blade.
- 2 × 20V 4.0Ah PowerShare batteries (they operate together to give 40V of power at 4.0Ah).
- Dual charger so you can charge both batteries at once.
- 40 L (≈10.6 US gallons) grass collection bag with mesh sides and a solid top.
- Mulching plug for converting from collect to mulch mode.
- Assembly hardware and a clear user guide.
Two 4.0Ah batteries included is a big plus. Many brands bundle two smaller, 2.0Ah batteries which give poorer run time; here you get higher-capacity packs, and a dual charger so charging time doesn’t become a bottleneck.
First impressions — build quality and design
From the moment I unpacked it, the WG737E felt solid. The deck uses a double-skin design which gives it rigidity — it doesn’t flex like cheaper single-skin decks. The plastics and fittings feel robust and I could tell it would stand up to regular use.
The mower is lightweight for a machine with this spec — advertised at roughly 33 lb (15 kg) — which makes it easy to manoeuvre and lift into a car or onto a shelf. The rear wheels are larger than the fronts, which improves handling over bumps and around borders.
Assembly — fast and simple
Assembly is straightforward and designed to be done by one person in a few minutes. The handlebar sections are indexed so you can’t install them the wrong way; there are quick-release bolts and levers at the lower and midpoint of the handle so you can fold the mower down flat for storage.
- Install the lower handle pieces (left and right) making sure the grooves align with the slots on the deck.
- Select your handle height via the three-angle positions — the bars are adjustable for comfortable posture.
- Fit the upper handle section, thread the bolt from the inside out and fasten the quick-release nut.
- Clip the cable tidy clips to keep the control cable neatly routed along the handle.
- Assemble and attach the 40 L grass collection bag: back piece in first, then click the front onto the frame and hook the mesh sides in place.
The small touches stand out: the grass box top is solid to block dust, the mesh sides provide good airflow and the flap on the back includes a little handle for easy lifting. Even simple things — like the mulching plug having a release button and the power gauge on the top — make the mower feel well thought out.

Note on that last line: “ideal up to 1/4 acre” is a practical guideline, because runtime depends on grass length, density and terrain. In my real-world test, on a lawn around 4,300 sq ft (≈400 m²) the mower handled the job comfortably on a single charge with the two 4.0Ah packs. If you have a full 1/4 acre, stiffer longer grass, or a lot of slopes, expect shorter run times and factor in battery rotation or a spare pack.
The WG737E uses two 20V Worx PowerShare batteries that work in parallel to give 40V of cutting power while still using the 20V battery ecosystem. Both batteries operate together in the mower — you don’t run one then swap to the other; both sit in the front compartment and feed the brushless motor together. Because they are 4.0Ah packs, you get respectable run time compared with the smaller 2.0Ah packs plenty of other makers supply.
PowerShare is a big advantage if you already own or plan to own other Worx tools. The same batteries can be used across grass trimmers, hedge trimmers, blowers and more, so buying bare tools in future can be more economical — you can share those batteries rather than buying a different battery for each tool.
Charging: the dual charger supplied lets you charge both batteries simultaneously which means downtime is minimal. The batteries also have individual charge level indicators you can press to check the remaining charge, plus there’s a combined battery gauge on the mower so you can see how much combined charge you have left before you start mowing.
Brushless motor and IntelliCut
This mower uses a brushless motor. In simple terms, brushless motors are more efficient, quieter and have fewer wear parts compared to brushed motors. The WG737E also benefits from intelligence in the power delivery: when the grass gets tougher the motor ramps up, and when the load eases it steps down — which helps conserve battery and preserve runtime.
During testing, I could clearly hear the motor step up as I hit thicker, longer patches and step back down on easier sections. That immediate response makes mowing feel smooth and efficient and reduces battery drain when you don’t need all the power.
Cutting performance — bagging and mulching
The Worx WG737E comes with a mulching blade and a mulching plug, and I tested both modes. The deck and blade do two important jobs well: they cut cleanly and they have good cut-to-edge performance so you get a closer cut near walls and fences.
The grass collector is my preferred style: mesh sides with a solid top. The mesh helps airflow so clippings are packed into the box from back to front, while the hard top prevents dust from blowing up at you when the grass is dry. The box has a full-flap indicator which falls down when circulation stops — it’s a simple mechanical flag that tells you to empty the box.
On collection: the WG737E filled the 40 L bag efficiently — clippings were packed from the back forward, not just dumped at the front like some poor designs. That means you use the full volume of the box before needing to stop.

On mulching: the included mulching plug is easy to install and remove due to a small release button. When used correctly (i.e., frequent light cuts rather than trying to mulch long overgrown grass) the mulching function produces fine clippings that quickly break down and feed nutrients back into the turf — a helpful tool during dry weather to retain moisture and nutrients.
Important mulching tip: to mulch successfully you must cut regularly and remove only a small percentage of the blade each cut. If the grass grows long and you try to mulch a heavy cut you’ll end up with clumping. Keep your mower at the same setting when mulching and mow weekly during the growing season for best results.
Practical cutting tests — regular and long grass
I ran a few real-world tests on my lawn.
- Test 1: Regular, maintained lawn set to ~2″ (50 mm) // actual position used in test roughly the middle settings — this produced a clean finish and the bag filled well from back to front.
- Test 2: Mulching after reducing height slightly — mulched clippings were fine and visible return to turf looked healthy.
- Test 3: Very long, tough grass at the far end of the lawn (higher setting): the motor stepped up and the mower powered through without bogging — the response is immediate from the brushless motor and the dual batteries working together.
One key takeaway: this machine handles both regular and longer cuts surprisingly well for a 16″ (40 cm) cordless mower, largely due to the 40V combined battery and brushless motor. For domestic users switching away from petrol, the WG737E gives comparable cutting power for typical garden duties without fumes, excessive noise or petrol maintenance.
Controls, ergonomics and storage
The handlebar uses a cross-bar style starter/drive bar that I prefer. It feels like a petrol mower setup and gives me control to steer with one hand during tight turns while still keeping the mower running. The handle padding is comfortable and the handle angle has multiple positions so you can select a posture that suits your height.
Storage is compact due to folding handles and the collapsible grass box. With the two quick-release levers you can fold the mower into a neat package that fits easily in a shed or garage and won’t take up much shelf space.
What this mower doesn’t give you
No mower is perfect. The one feature I noticed missing that matters to some users is a rear roller. This mower doesn’t have a rear roller so you won’t get the striped lawn finish that a cylinder or roller-equipped rotary mower can produce. If striping is a key priority for you, this model is not intended for that purpose.
Other than that, I struggled to find major faults. Build quality, collection and mulching performance and battery system are all very good for what the mower costs.

Durability, warranty and long-term ownership
Worx offers a 3-year standard warranty on this model with the option to register and extend to 5 years (3+2). That extended warranty is a reassuring feature and worth registering for after purchase.
From experience with other Worx tools: their batteries and electronics are durable when used and stored sensibly. I have several older Worx tool batteries that are still performing well after years of domestic use — the PowerShare ecosystem is solid and gives you investment protection if you add additional Worx tools over time.
Run time expectations and sizing your lawn
Run time depends on load. The two 20V 4.0Ah batteries supplying a brushless motor will give varying runtimes depending on terrain and grass density. During my test on a lawn of roughly 4,300 sq ft (≈400 m²) the mower completed the cut comfortably on a single charge. If your lawn approaches that 1/4 acre guideline, or you have very long grass and slopes, plan for either breaking the job into two sessions or having a spare battery ready.
General guidance:
- For small to medium lawns up to around 4,000–5,000 sq ft (≈370–465 m²): expect a single charge to be adequate for a typical weekly cut if the grass is maintained.
- For larger lawns approaching 1/4 acre (≈10,890 sq ft / ≈1,012 m²): you may need to charge and change batteries mid-job or consider a larger deck mower or additional battery capacity.
Remember: higher blade settings, wet/long grass, and steep slopes reduce runtime; finer, regular mowing uses less battery because the motor doesn’t have to work as hard.
Maintenance and tips to get the best from the WG737E
Keeping your Worx WG737E in top condition is straightforward. Here are my recommended maintenance steps and tips:
- After each mow, empty the grass bag and brush any trapped grass from the deck and mesh sides. A quick blow or brush keeps airflow consistent.
- Periodically remove the battery pack(s) and clean the contacts with a dry cloth. Avoid corrosive cleaners.
- Sharpen or replace the mulching/cutting blade annually or after any impact. A sharp blade delivers cleaner cuts and reduces stress on the motor.
- Inspect the deck for dents or heavy damage — the double-skin deck is durable but hitting hidden objects should be avoided.
- When storing for winter, remove batteries, charge them to around 30–50% for long-term storage and store them indoors at moderate temperatures. Cold batteries tend to lose capacity temporarily.
- Use the mulching plug correctly: only mulch when the lawn is regularly maintained and you are cutting a light amount off the top.
Accessories and optional extras I recommend
- Extra 4.0Ah PowerShare battery — if you have a larger lawn or prefer uninterrupted mowing.
- Replacement blade(s) — keep a spare sharp blade to swap quickly when needed.
- Waterproof cover for the mower if you store it outside (still better to keep in a shed or garage).
- Spare grass collection bag if you rely on bagging and want to switch to an empty one without stopping to empty.
Who is this mower best for?
The Worx WG737E is a great choice if you:
- Have a medium domestic lawn up to about 1/4 acre and prefer cordless convenience.
- Want a lightweight, easy-to-store mower with folding handles and good build quality.
- Value the PowerShare battery system and want to leverage those batteries across multiple Worx tools.
- Like the option to both bag cuttings and mulch for turf health and moisture retention.
If you need a striping finish or a professional-grade, large-area mower for acre-plus properties, then a different machine (cylinder mower for stripes or a ride-on / commercial petrol for very large areas) will be more appropriate.
Pros and Cons — my concise summary
Pros
- Supplied with two 20V 4.0Ah batteries and dual charger — good runtime and fast turnaround.
- Brushless motor with intelligent power stepping — efficient and quiet.
- Solid double-skin deck and good build quality for the price point.
- Excellent grass collection thanks to mesh sides and solid top box (40 L / ≈10.6 US gallons).
- Mulching plug included and easy to use.
- Lightweight (≈33 lb / 15 kg) and easy to manoeuvre with larger rear wheels.
- Folding handles for compact storage.
- PowerShare battery compatibility across Worx tools; 3-year warranty extendable to 5 years.
Cons
- No rear roller — no striping capability for those who want a show-lawn finish.
- As with any cordless mower, runtime depends on your lawn conditions; larger lawns may require extra batteries.
My verdict — would I recommend the Worx WG737E?
Yes. For the vast majority of domestic users who want the convenience of cordless without compromising on cut quality, the WG737E is an excellent choice. It handles regular and longer grass well, has good grass collection and mulching performance, and benefits from the PowerShare battery ecosystem. The brushless motor keeps noise down and efficiency up, and the solid build inspires confidence.
If your priorities include a striped finish or commercial heavy use on several acres, look elsewhere. But for home gardeners with up to about 1/4 acre and a desire to ditch petrol, this model is a top contender in its class.
Frequently Asked Questions (FAQ)
Q: How long will the batteries last on a single charge?
A: Run time varies with grass height, density, slope and cutting height. In my test on a maintained lawn of about 4,300 sq ft (≈400 m²), the mower completed the job on a single charge using the two supplied 4.0Ah batteries. Expect shorter runtimes on very long or dense grass, and plan for a spare battery if you regularly mow near the upper limit of the “ideal” size.
Q: Does it mulch well?
A: Yes — the mulching plug and mulching blade do a good job, especially when you mow frequently and only remove a small amount each time. Mulching is particularly useful in dry weather to help retain moisture and return nutrients to the turf. Avoid trying to mulch when the grass is very long or wet.
Q: Can the mower cut close to edges?
A: Yes — the blade design includes comb-style edges that pull grass toward the blade when you run close to walls or fences, giving a closer cut to the edge than some other rotary mowers.
Q: Is this mower noisy?
A: No — cordless brushless motors tend to be significantly quieter than petrol engines. The WG737E is quiet enough to use without disturbing neighbours, while still delivering strong cutting power.
Q: Is it easy to store?
A: Absolutely. The handles fold down quickly using the two quick-release levers and the grass catcher is folding and compact. At around 33 lb (15 kg), it’s light enough for most people to lift and store on a shelf or in a garage.
Q: How does it compare to petrol mowers?
A: For domestic use up to around 1/4 acre, cordless mowers like this one are a very attractive alternative: no petrol, no fumes, less noise and reduced maintenance. Petrol still can be useful for very large or commercial lawns where continuous run time and refuelling speed are critical, but for home gardeners cordless technology has matured to the point where it meets most needs.
Q: Can I extend the warranty?
A: Yes — Worx offers a 3-year base warranty and you can register the product to extend it by 2 years for a total of 5 years (3+2). I recommend registering after purchase for added peace of mind.
Buying tips and final notes
- If you already own Worx tools, the PowerShare batteries make this model even more attractive — you can reuse existing batteries.
- Buy an extra 4.0Ah battery if you have a larger lawn or want the convenience of uninterrupted mowing without stopping to charge.
- Register your mower with Worx for the extended warranty.
- Keep a sharp spare blade on hand for quick swap-outs — a sharp blade helps cut more cleanly and reduces motor load.
If you want a compact, well-built cordless mower that offers a good balance of power, runtime and features (mulch and bag), the Worx WG737E is a compelling option. It’s particularly well suited to gardeners who value low noise, lower maintenance and the convenience of battery-powered equipment.
