Hi, I’m Mark from EasyLawnMowing. Over the past few weeks I’ve been testing the WORX Nitro WG761-4 80V self-propelled cordless lawnmower and in this review I’ll walk you through exactly what you get in the box, how it goes together, the technology underneath, and most importantly how it performs on a real lawn — from long, tussocky grass to a fine, mulched finish.
This is my take from hands-on use: the WG761-4 is designed to replace petrol mowers in larger gardens and it’s built to a premium spec. I’ll be candid about its strengths and where it might not be the right choice for everyone. If you want the short verdict: it’s a heavy-duty cordless mower with genuine power and professional features, but it demands a premium investment.

Contents and Unboxing — What’s in the Box?
Opening the box felt like unboxing a piece of pro equipment. This is not a toy — the WG761-4 arrives heavy and well-packed. The package is substantial because the mower itself weighs just shy of 82 lb (about 37 kg). If you’re unboxing one of these, get a friend to help lift it or slide it out on its side rather than trying to lift it by yourself.

Here’s everything you’ll find in the kit:
- The mower itself — pre-assembled with folding handles.
- 4 × 20V 4.0Ah PowerShare batteries (supplied) that together form the 80V system.
- Base Camp charging station (holds and charges all four batteries at once).
- A large 70 L (about 18.5 US gallons) grass collection bag.
- Side discharge chute for side ejection.
- Safety key and minimal user documentation.
One thing to note: you don’t get a single external charger for each individual battery because the kit uses the Base Camp system. The Base Camp docks on top of the mower and houses all four batteries; when you need to charge, you release the Base Camp and plug it into mains. That’s very convenient for charging all batteries together and makes daily use painless.
Assembly — Minimal, Fast and Clever
Assembly is deliberately simple — the mower arrives essentially ready to go. The only part you’re likely to fit yourself is the grass catcher frame. The handles fold open with a quick orange button and the catcher clips on with three easy fastenings. Total time from box to operation is minutes rather than hours.
Practical touches that make assembly easy:
- Wire-frame insert for the bag simply snaps over the top and clips into position.
- Two clips on the sides secure the bag to the mower body; no fiddly zips or fasteners.
- Folding handles lock into position quickly and let you set an ergonomic user height.
For users who like to get straight to work this is a huge advantage. The less time you spend assembling and the sooner you’re mowing, the better.

Build Quality and Design
From the moment you pick it up, you notice this mower is built like a machine that’s designed to replace petrol equivalents. The deck is steel rather than plastic — that gives it a reassuring weight and durability. The wheels are rubber; the rear wheels are notably larger, which helps when pushing across uneven ground and when the mower is self-propelling under load.
Small but meaningful design touches I appreciated:
- Steel deck surface is smooth — no sharp edges or deep grooves — which makes cleaning much easier and reduces clippings build-up.
- Large diameter rear wheels increase traction and make it easier for the drive system to move the heavy chassis forward.
- LED front light for low-light working.
- Handles with angle adjustment allow you to set a comfortable posture to avoid back strain.
Worx’s approach here is a smart one. Instead of shipping a single big battery pack, the mower uses four 20V 4.0Ah batteries. These fit into a removable Base Camp which itself sits on top of the mower. When it’s time to charge you press the red release, pull the Base Camp off and plug it into the mains.

Why this matters:
- Charge all four batteries at the same time in the Base Camp — no need to juggle single chargers.
- The same 20V batteries are compatible with a large range of Worx PowerShare tools, giving you cross-tool compatibility.
- The system allows you to use individual batteries in other tools if you prefer — flexibility for homeowners with multiple cordless tools.
Some technical specifics worth noting: each battery is rated at 20V and 4.0Ah. Wired in series to reach 80V, the pack retains 4.0Ah capacity but delivers 80V. That equates to roughly 320 Wh of energy available in the assembled pack (80V × 4.0Ah). In practical terms, the actual run time will depend on conditions — grass length, density, and use of self-propulsion all affect power draw — but the system is designed for larger lawns and heavier work.
Charging and Run-Time
The Base Camp is the charger. In the kit I tested, the charger is a fast unit — the manufacturer quotes a rapid recharge capability. In practical terms the Base Camp plus charger supplied will top up your batteries in a few hours. The exact time will depend on how depleted the batteries are and the charger supplied with your specific package; in many kits the bundled fast charger will recharge the Base Camp in about four hours.
If you plan long sessions, consider a second set of batteries if you routinely mow large acreage. However the advantage here is the simplicity: the Base Camp charges all four cells together, and those same batteries are usable across other Worx tools.
Cutting Options — Bagging, Mulching and Side Ejection
This is a true 3-in-1 mower:
- Bagging: effective cut-and-collect into a large 70 L bag that fills evenly thanks to good airflow.
- Mulching: no separate plug is needed — a lever inside the deck deploys a mulching flap. The blade is a mulching blade and chops clippings finely before returning them to the lawn.
- Side ejection: a supplied chute clips on to the deck for side discharge when you want to quickly cut without collecting.
I particularly liked the mulching implementation. Instead of forcing you to fit a separate mulching plug, the WG761-4 uses an internal flap controlled by a lever. Close the flap and the deck becomes a mulcher — the blade works like a kitchen blender, recutting clippings until they’re fine enough to fall back into the turf. In the hot, dry spells this year, that returned organic matter helps keep the lawn looking greener and reduces water loss.
Height Adjustment — Seven Positions from 1.5″ to 4″
The height adjustment system is among the best I’ve used for a mower in this category. There are seven positions spanning 1.5″ to 4″ (38 mm–102 mm). The mechanism is a single lever with a push-button that lets you move the deck to the exact notch — it locks secure and there’s a visual gauge on the deck so you can return to a preferred setting easily.
That range covers everything from close, formal cuts to higher summer settings when you want to leave more blade for drought tolerance. Being able to go as low as 1.5″ is impressive for a rotary mower of this size, and the higher stops at 4″ make it useful for longer grass and seasonal situations.
Controls, Ergonomics and Storage
The handlebar layout is intuitive with one continuous crossbar — much like a petrol mower — which I favour because it gives balanced control for both left- and right-handed users. The starter is a simple button: press, hold the safety lever and engage the blade. The self-propelled drive is operated by a central lever and there’s a variable speed control right at the top so you can fine-tune the walking pace.

Two ergonomic features stood out:
- Angle-adjustable handles — there’s an orange release that lets you tilt the handle to a comfortable height and posture for pushing. For me that made a real difference to back comfort.
- LED headlight — small, but useful if you mow early or late in the day.
Storage is well thought out. The bars fold flat and the mower can be stood vertically to save floor space. Worx includes hooks on the grass collection box so you can hang or hook the bag in the vertical position and even tuck the side chute inside the bag for compact storage.
Under the Deck — Blade, Airflow and Cleanability
Flipping the mower for inspection shows a clean, unobstructed steel deck. The interior has been kept smooth and free of grooves — this helps prevent clumping and makes cleaning straightforward. The supplied blade is a mulching blade which is sharpened and formed to re-cut clippings into fine particulates for return to the turf in mulching mode.
Airflow is excellent. When I tested bagging, the collection bag filled evenly and clippings reached the back of the bag rather than piling up at the front — that’s a sign of good circulation. It’s one of those small details that often separates an economical kit from premium performance.
Testing: Real-World Performance — Bagging, Side Discharge, Mulching
Let me be blunt: I didn’t test this on my small lawn because we’ve had a very dry season and there wasn’t enough growth. Instead I took the mower to a neighbour’s garden with long, dense grass — an ideal environment to push the WG761-4 and find out whether it lives up to the petrol-replacement claim.
I started with the Base Camp fully charged (all four cells topped up). For the first pass I set the cutting height to position 3 — roughly around 1.4″–1.5″ below typical lawn length — and I started on the slowest self-propelled speed to show the minimum pace. The motor reacted exactly how I wanted: as soon as the blade hit the longer, thicker growth the motor stepped up to supply more torque and then eased back when load reduced. That dynamic response is important because it prevents the mower staying in a high-power state longer than required and helps preserve battery energy.
On minimum self-propulsion it moves at a very slow walking pace. For some people that’s exactly what they want — a slow, controlled start that lets you align rows and navigate obstacles without the mower overshooting. When you need to speed up, the variable drive increases smoothly to a brisk walking pace — the top speed is genuinely quick for a self-propelled domestic mower and it makes getting larger areas done faster.
Bagging
Bagging performance was excellent. The bag is huge — 70 L (≈18.5 US gallons) — and it filled evenly from front to back. That even distribution is the sign of efficient deck airflow and suction. I was impressed to see the bag filling all the way to the rear rather than clogging at the front as many poor designs do.
Side Discharge
The side chute simply clips on and the internal lever flips the rear flap to side discharge mode. The ejection is powerful and throws clippings clearly away from the cutting path — ideal for quick clears or when you’re mowing rougher areas where collection would be impractical.
Mulching
Mulching worked well. I set the mower to mulch on the freshly cut area (mulching is not for very long growth — you should mulch over an already cut surface) and the deck re-chopped clippings multiple times. When I brushed the grass afterwards I could see fine particles flicking up — that’s the mulch returning to the lawn. In dry spells it’s especially handy because the mulched material helps feed and retain moisture in the root zone.
Long Grass Test
Perhaps the most crucial real-world test was tackling truly long grass. I pushed this mower into tussocky, tall growth and it handled it with no drama — the motor stepped up, the blade never laboured, and the drive kept it moving forward. It felt comparable to a petrol mower in terms of raw ability. If you’re worried cordless can’t handle tough, tall work — this is a compelling example that it can.
Drive System: Self-Propelled Variable Speed
The drive is variable and genuinely adjustable across a broad range. On the lowest setting the mower ambles forward slowly; on the top setting it’s a fast walking pace. The advantage is obvious: you can adapt the pace to the job — slow for precision edges and slopes, fast for long straight runs.
Two further practicalities:
- You can engage the self-propulsion without the blades running to move the mower from storage to the lawn — a handy feature for this heavy machine.
- When you disengage the drive, the mower is immediately free to be pulled back. Some models require a short delay before you can pull them backward; the WG761-4 releases immediately for smooth manoeuvring around obstacles and under hedges.

Noise, Vibration and User Comfort
Because the motor is brushless and the power source is battery rather than petrol, the WG761-4 is surprisingly quiet for an 80V machine. It’s not whisper-quiet — you’re still cutting grass — but it’s significantly less intrusive than a petrol equivalent. Vibration is well controlled and handle ergonomics minimise fatigue over longer sessions.
Maintenance — What to Keep an Eye On
Routine maintenance is straightforward:
- Keep the underside of the deck clear of compressed clippings — the smooth deck helps reduce adhesion but regular checks are still wise.
- Sharpen the blade annually or as needed. The supplied mulching blade works for all three modes but it still benefits from a sharp edge for clean cuts.
- Store batteries in a cool, dry place and keep them charged between uses for longevity.
- Check wheel bearings and drive components annually if you use the mower heavily.
The brushless motor requires less maintenance than brushed motors — fewer parts wear — and contributes to the extended warranty Worx offers on these models.
Warranty & Longevity
Worx supports this mower with a 2-year warranty that extends to 5 years when you register the product. That reflects confidence in the brushless motor and the overall build. In my experience with Worx products over the years, the battery tech and electrics have proven robust — I still have an older Worx mower working with original batteries after multiple seasons.
Pros and Cons — My Honest Summary
Pros
- Build quality is excellent — steel deck, rubber tyres, robust chassis.
- Power delivery feels like a petrol mower; it handled long, dense grass without bogging.
- 80V system with four 20V PowerShare batteries offers flexibility across other tools and a removable Base Camp for quick charging.
- Large 70 L collection bag with good circulation for even filling.
- Brushless motor: quieter, more efficient, longer lasting.
- Variable self-propelled drive with a wide speed range — very user-friendly.
- Seven cutting heights from 1.5″ to 4″ (38 mm–102 mm), suitable for all seasons.
- Vertical storage with smart bag hooks and compact footprint.
- Outstanding warranty potential — up to 5 years when registered.
Cons
- Price: this is a high-end machine and the initial outlay reflects that. If you only have a small lawn, it may be overkill.
- Weight: at just under 82 lb (about 37 kg) it’s a heavy mower — most users will want the self-propel feature to move it comfortably.
- If you don’t already use Worx PowerShare batteries across other tools, the system’s full value is reduced — you’re buying into an ecosystem.
Who Is the WORX Nitro WG761-4 80V Best For?
This mower is aimed squarely at the homeowner or small gardener who wants petrol-level performance without petrol. It’s ideal if you:
- Have a larger garden up to around 10,800–12,900 ft² (1,000–1,200 m²).
- Want a premium, durable mower that can handle long, tough grass as well as fine finish work.
- Value cross-tool battery compatibility with the Worx PowerShare ecosystem.
- Appreciate convenience features like Base Camp charging, vertical storage and variable self-propulsion.
It’s probably not the best buy if you have a very small lawn and minimal storage space, or if you’re extremely budget conscious — there are cheaper cordless options for small yards.
Practical Tips and My Recommendations
- Charge the Base Camp after every major mow. Leaving batteries discharged long-term reduces shelf life.
- Use the lowest recommended cut approach for long growth: don’t remove more than one-third of the blade length at once; if you have very tall grass, take two passes.
- Mulch on already-cut areas, not directly into very long or wet grass; mulching excels when clippings are already short.
- Use the variable self-propulsion to set a comfortable walking pace — it’s far better than fighting a fixed-speed drive.
- Register the mower to unlock the additional three-year warranty extension — it’s worth taking the minute to do so.
Frequently Asked Questions (FAQ)
How long will the mower run on a single charge?
Run time depends on many factors: grass length, terrain, how much you use the drive and what cutting height you choose. As a rough guideline: with four fully charged 20V 4.0Ah batteries in the Base Camp, you’ll get substantial run times suitable for medium-to-large lawns. If you need guaranteed extended runtime for very large properties, consider a spare set of batteries.
How fast does the Base Camp charge the batteries?
The supplied fast charger will recharge the Base Camp typically within around four hours, but the exact time can vary slightly depending on the charger variant and the battery condition. The convenience is you can charge all four cells simultaneously in the Base Camp.
Can the individual batteries be used in handheld tools?
Yes — the individual 20V batteries are PowerShare compatible and can be used in hundreds of Worx tools if you choose to buy them. This gives much better value if you have multiple Worx products.
Is this mower as powerful as a petrol mower?
In my testing, especially during the long grass trial, the WG761-4 showed petrol-equivalent performance. Worx positions this machine as comparable to a 170cc petrol mower in terms of cutting ability — importantly the brushless motor and 80V architecture deliver the torque needed for heavier cuts.
How heavy is the mower to move and store?
At just under 82 lb (≈37 kg) it’s a heavy machine, which is why the self-propelled drive is essential for many users. The drive also works without the blade engaged so you can move it from storage to the lawn easily. For storage, fold the handles and stand it vertically — the bag hooks keep the footprint compact.
Does it need a mulching plug?
No. The WG761-4 uses an internal flap activated by a lever to convert the deck to mulching mode. That’s a tidier, easier solution compared to removable plugs that can be lost or forgotten.
What is the warranty?
The mower comes with a 2-year standard warranty and provides an extra 3 years (bringing it to 5 years total) when you register the product with Worx.
My Final Verdict
The WORX Nitro WG761-4 80V is a robust, well-engineered cordless lawnmower that genuinely delivers petrol-level performance for larger gardens. Its steel deck, brushless motor, Base Camp charging system and variable self-propel drive all demonstrate a clear focus on durability, convenience and real-world performance. The machine doesn’t skimp on professional touches: the wide speed range, efficient bagging, and effective mulching all stand out in daily use.
The trade-offs are obvious: it’s a premium purchase and physically heavy. If you have a small lawn, low budget, or won’t benefit from the PowerShare ecosystem, it may be excessive. But if you want to move away from petrol, value low noise and maintenance, and need a mower that can handle long grass and large yards, it’s a seriously compelling option.
