Webb Eco 40V Cordless Lawnmower 43cm Review: The Cordless Freedom Your Garden Deserves

For years, mowing my medium-sized lawn was a weekly chore I genuinely dreaded. It was a constant battle, a three-act play of frustration. Act one involved wrestling with our old, cumbersome petrol mower, a beast that weighed a ton and often refused to start without a ritual of choke-pulling and prayer. Act two was the noise and fumes, an assault on the senses that left me smelling like a garage. Act three was the cleanup, an oily, messy affair. Then we switched to a corded electric model, trading fumes for the endless, infuriating dance of managing the power cable—avoiding flowerbeds, untangling it from the rose bushes, and the ever-present fear of accidentally running it over. Mowing the lawn felt less like gardening and more like a punishment. It’s this very frustration that sent me on a quest for a better way, a solution that promised power without the petrol and freedom without the cord.

What to Consider Before Buying a Cordless Rotary Mower

A cordless rotary mower is more than just a garden tool; it’s a key solution for reclaiming your time and sanity. It’s designed to provide the untethered freedom of a petrol mower with the low-maintenance, quiet operation of an electric one. The main benefit is liberation—the ability to move freely around your garden, navigating trees, paths, and garden furniture without being tethered to a power socket. They solve the problem of noise pollution, emissions, and the hassle of storing fuel, making lawn care a more pleasant and environmentally friendly experience for anyone with a small to medium-sized lawn.

The ideal customer for this type of product is someone with a lawn that’s too large for a small corded mower to be practical, but who doesn’t want the weight, noise, and maintenance of a petrol engine. If you value convenience, quick setup, and quiet operation, a cordless model is for you. However, it might not be suitable for those with exceptionally large grounds (an acre or more), where a petrol ride-on mower or a professional-grade self-propelled model might be more efficient. Similarly, for those with very small, postage-stamp-sized lawns, a simpler, more compact corded model might be all that’s needed. But for that common middle ground—the typical British garden—a powerful cordless mower often hits the sweet spot.

Before investing, consider these crucial points in detail:

• Cutting Width & Storage: The cutting width dictates how many passes you’ll need to make. A wider deck, like the 43cm one on the Webb Eco, significantly reduces mowing time on medium lawns compared to smaller 32cm models. Also, consider storage; look for models with handles that fold down easily to minimise the footprint in your shed or garage.
• Battery Performance & Runtime: This is the heart of any cordless mower. Look at the voltage (V) for power and the amp-hours (Ah) for runtime. A 40V system is robust for tougher grass, and dual batteries, like those offered with the Webb Eco 40V Cordless Lawnmower 43cm, can extend the runtime significantly, often enough to tackle the whole lawn in one go.
• Materials & Durability: Mower decks are typically made of plastic or metal. While metal is traditionally seen as more durable, modern high-impact polymers are incredibly tough, rust-proof, and have the significant advantage of being much lighter, which greatly improves manoeuvrability.
• Ease of Use & Maintenance: Features like a single-lever height adjustment save time and frustration compared to adjusting each wheel individually. Furthermore, a brushless motor is a huge plus, offering greater efficiency, a longer lifespan, and virtually zero maintenance compared to older brushed motors.

Understanding these factors will ensure you choose a mower that not only cuts your grass but also makes the entire experience more efficient and enjoyable.

While the Webb Eco 40V Cordless Lawnmower 43cm is an excellent choice, it’s always wise to see how it stacks up against the competition. For a broader look at all the top models, we highly recommend checking out our complete, in-depth guide:

Unboxing and First Impressions: A Refreshingly Simple Start

Upon receiving the Webb Eco 40V Cordless Lawnmower 43cm, the first thing that struck me was the simplicity of the assembly process. Often, unboxing a new mower means an hour spent deciphering confusing diagrams and wrestling with a bag full of nuts and bolts. Not here. As one user aptly noted, assembly was “minimal… honestly a couple of minutes,” and my experience was identical. The main components click and lock into place intuitively, primarily just attaching the handle sections. It was a pleasant and welcome change.

Out of the box, the mower has a sturdy, purposeful look. The main body is constructed from a tough, thick green plastic. While some may prefer the heft of a steel deck, I found the polymer construction to be a major advantage. It feels robust and durable, yet the entire unit weighs just over 16kg. This is light enough to be carried one-handed, a feat unimaginable with my old petrol mower. This low weight immediately signals that manoeuvrability will be a key strength. The dual 20V batteries feel solid, and the dual charger is a practical touch, allowing both to be charged simultaneously. My initial impression was of a well-designed, user-focused machine built for convenience, a feeling you can explore further by viewing its full specifications.

In-Depth Performance Analysis: Putting the Webb Eco 40V to the Test

A mower can look great and assemble easily, but its true worth is proven on the turf. We put the Webb Eco 40V Cordless Lawnmower 43cm through its paces on a variety of lawn conditions, from neat, flat sections to more challenging, uneven areas with longer, damper grass left after a week of British rain. The goal was to see if its real-world performance lived up to its impressive specifications.

Power System & Runtime: The 40V Brushless Heart

At the core of this mower lies its 40V power system, achieved by intelligently linking two 20V 4.0Ah batteries. This design provides the torque and blade speed needed to rival petrol models, slicing through grass cleanly rather than tearing it. The real star, however, is the brushless motor. This advanced technology is a significant step up from older brushed motors, offering superior efficiency, which translates directly into longer runtime from the batteries. It also runs cooler, generates less noise, and has a much longer operational lifespan as there are no brushes to wear out. During our test, the difference in noise level compared to a petrol mower was night and day; it’s quiet enough that you could mow on a Sunday morning without worrying about disturbing the neighbours.

Webb claims a runtime of up to 60 minutes, and in our testing on a standard, well-kept lawn, we came very close to that figure. When we moved to the tougher, longer grass, the mower drew more power and the runtime dropped to around 45-50 minutes, which is still incredibly impressive and more than enough to handle a medium-sized lawn of up to 450m². The included dual charger is a brilliant addition, replenishing both batteries simultaneously in a reasonable time, meaning you’re quickly ready for the next mow. This robust battery performance is a feature that truly sets it apart in the cordless market.

Cutting Performance & Versatility

Power is meaningless without a great cut, and this is where the Webb Eco 40V Cordless Lawnmower 43cm truly excels. The 43cm (17-inch) cutting width is generous, making a noticeable difference in reducing the number of passes required compared to more common 32-37cm models. This efficiency gain really adds up over the course of mowing an entire lawn.

The versatility is anchored by its excellent height adjustment system. A single, large, easy-to-grip lever allows you to switch between six different cutting heights, ranging from a close 25mm for a bowling-green finish to a lengthy 75mm for the first cut of the season or for tackling overgrown areas. This single-point adjustment is a massive quality-of-life improvement, saving you from the tedious task of setting the height on each wheel individually. During our tests, we started high on a neglected patch of lawn and progressively lowered the deck with each pass, and the mower handled it without bogging down or stalling. The cut was consistently clean and even across all heights. The 50-litre collection bag is also cleverly designed with a mesh fabric that promotes airflow, helping to compact the clippings efficiently and ensuring it fills up completely before the ‘bag full’ indicator shows. We were able to mow for longer periods before needing to make the trip to the compost bin, a small but appreciated time-saver.

Design, Ergonomics, and Usability

This is arguably the area where the Webb Eco 40V shines brightest. Its exceptional usability stems directly from its lightweight design. At just 16.1kg, it feels nimble and responsive. We found ourselves effortlessly navigating around obstacles like our bird bath and garden path, a task that used to require a three-point turn with our old petrol mower. This ease of movement transforms mowing from a physical chore into a far more pleasant walk. This sentiment was perfectly captured by a user who noted it was “lightweight enough to be carried one handed” and performed brilliantly on their garden with “more ups and downs than an EastEnders episode.”

Our experience confirmed this entirely. On sloped and uneven sections of our lawn, where heavier mowers tend to scalp the high spots, the light frame of the Webb allowed it to glide over the contours smoothly. While it isn’t self-propelled, its lack of weight means you barely notice. Pushing it requires minimal effort, making it a fantastic choice for users who may lack the physical strength to wrangle a heavy machine. When the job is done, the handles fold down quickly and compactly, allowing the mower to be stored vertically against a wall or tucked away on a shelf, freeing up valuable floor space in the shed. The combination of its low weight, wide cut, and hassle-free operation makes the Webb Eco 40V Cordless Lawnmower 43cm a joy to use.

What Other Gardeners Are Saying

Looking at feedback from fellow users, a clear and consistent picture emerges that strongly supports our findings. The most frequently praised feature is the near-instant setup, with one gardener remarking that the “minimal assembly required” was a “pleasant change from most lawnmowers.” This out-of-the-box readiness is a significant selling point.

Furthermore, its performance on challenging terrain receives high marks. We found comments highlighting its ability to cope with “long damp grass on a garden that has more ups and downs” than they expected. For many, like us, who have struggled with petrol mowers being too heavy and hover mowers being too small, the Webb Eco 40V hits a perfect balance. Its lightweight nature is consistently mentioned as a key benefit, making it suitable for a wide range of users. While feedback is overwhelmingly positive, the only potential critique one might infer is that for those with very large, hilly gardens, the lack of a self-propel function might eventually lead to fatigue, though its featherlight construction makes it far less of an issue than with other push mowers.

How the Webb Eco 40V Compares to the Competition

The Webb Eco 40V Cordless Lawnmower 43cm is a formidable contender in the cordless space, but it’s important to understand how it stacks up against other types of mowers. The alternatives are often corded electric models, which cater to different needs and budgets.

1. BOSCH ARM 3200 Electric Lawnmower

The Bosch ARM 3200 is a popular corded electric mower that targets a different user entirely. Its primary advantages are its lower price point and extremely light weight. However, these come with significant trade-offs. The 32cm cutting width is much narrower than the Webb’s 43cm, meaning it will take substantially longer to mow the same area. Its power is also limited by the cord, and you lose the “mow anywhere” freedom of a cordless model. This mower is best suited for someone with a very small, simple, flat lawn where a power socket is always nearby and budget is the primary concern.

2. Flymo Hover Vac 270 Electric Hover Lawn Mower

The Flymo Hover Vac 270 represents the classic hover mower design. It floats on a cushion of air, making it very easy to move sideways, which is useful for oddly shaped lawns or steep banks. However, it is severely limited by its tiny 27cm cutting width and minuscule 15L grass box, which requires constant emptying. Like the Bosch, it is corded, restricting its range. The Hover Vac 270 is a specialist tool for very small or uniquely challenging gardens, but it lacks the power, capacity, and cutting width of the Webb for tackling a typical medium-sized lawn efficiently.

3. Flymo SimpliGlide 360 Hover Lawn Mower

The Flymo SimpliGlide 360 is a step up from the Hover Vac, offering a more powerful motor and a wider 36cm cutting deck. It maintains the core benefit of a hover mower—excellent manoeuvrability on slopes and uneven ground. However, it still falls short of the Webb’s 43cm width and is bound by its 10m power cable. While a good option for those who are set on the hover principle and have a small-to-medium lawn, it doesn’t offer the raw convenience, power, and untethered freedom that makes the Webb Eco 40V Cordless Lawnmower 43cm such a compelling all-rounder.

Our Final Verdict: Is the Webb Eco 40V Cordless Lawnmower 43cm the Right Choice for You?

After extensive testing and analysis, we can confidently say that the Webb Eco 40V Cordless Lawnmower 43cm is a truly outstanding machine that redefines what to expect from a battery-powered mower. It successfully bridges the gap between petrol power and electric convenience, offering the best of both worlds. Its strengths are numerous: a powerful and efficient brushless motor, a long-lasting dual-battery system, a generous cutting width that saves time, and a wonderfully lightweight, ergonomic design that makes mowing less of a chore and more of a pleasure.
