Westinghouse 40V 18 Inch Brushless Cordless Lawn Mower Review

Have we ever wished mowing our lawn felt less like a chore and more like a quick, satisfying task we can actually finish in one go?

Why We Chose the Westinghouse 40V 18 Inch Brushless Cordless Lawn Mower

When we started looking for a new mower, we knew we wanted something cordless, low-maintenance, and powerful enough to handle real grass—not just perfectly manicured patches. The Westinghouse 40V 18 Inch Brushless Cordless (Push) Lawn Mower caught our attention because it promises gas-like performance without the gas headaches.

We also appreciated that it comes with two 4.0Ah batteries and a charger included, so we are not stuck buying extras on day one. In this review, we walk through what we have found in real-world use, what stands out, and where it might not be perfect for everyone.

Brushless Motor: Why It Actually Matters

We see “brushless” on a lot of power tools now, but we often wonder what difference it makes in everyday use. With this mower, the brushless electric motor is one of the big selling points, and in practice, we do feel the benefits.

A brushless motor typically means:

• More efficiency: Less energy wasted as heat, more turned into actual cutting power.
• Longer motor life: Fewer wear parts compared to brushed motors.
• Quieter operation: Not silent, but notably less noisy than a gas mower.
• Smoother performance: Less vibration, more consistent cutting feel.

In our experience, this translates into a mower that starts instantly, runs consistently without bogging down too easily, and does not feel like it is shaking our arms off. We also like that we are not dealing with spark plugs, belts, pull cords, or oil changes.

---

Battery System and Real-World Runtime

Any cordless mower lives or dies by its battery system. For this model, Westinghouse uses two 20V lithium-ion batteries working together for a 40V system. Each included battery is 4.0Ah, which is a decent capacity for home lawn care.

Westinghouse states we get around 25 minutes of real load runtime with both batteries installed. In our experience, that claim is fairly realistic, assuming:

• The grass is medium length (not a jungle).
• We are not constantly stopping and starting.
• We are mowing at a moderate pace on fairly level terrain.

How Far Does 25 Minutes Get Us?

We obviously vary in yard size, but as a general guide, we have found that this runtime is well-suited for:

• Small yards: Very manageable in one charge.
• Average suburban lawns: Often done in one charge if we mow regularly.
• Larger properties: Might need a second charge or a slower, more strategic approach.

We like that the mower takes standard Westinghouse 20V batteries, which helps if we already own other Westinghouse tools. It is also nice to have two batteries included, so we are not immediately forced to buy extras.

---

Cutting Performance: Power and Blade Speed

A mower can look great on paper, but cutting is what actually matters. With a maximum blade speed of up to 3100 RPM, this mower aims to provide a fast, even cut, even when the grass is a little on the tall side.

In practice, we notice:

• Consistent cutting quality on typical weekly mowing schedules.
• Reasonable performance on higher grass, although like any electric mower, we have to slow down a bit or raise the cutting height on very tall patches.

We do not see the same raw brute strength we might get from a big gas mower, but for regular residential lawns, the performance is impressive for a cordless unit. It handles thicker patches well enough when we are patient and we do not try to sprint through heavy growth.

---

18-Inch Cutting Path: Compact but Efficient

The 18-inch cutting width puts this mower in a sweet spot: wide enough that we are not endlessly going back and forth, but narrow enough to stay maneuverable.

We appreciate this format because:

• It navigates around trees, flower beds, and landscaping easily.
• It fits through narrower gates and storage spaces.
• It covers more ground per pass than smaller 14–16-inch models.

Westinghouse states that the mower provides edge-to-edge cutting, which we interpret as the blade and deck being designed so we can get close to edges without leaving a strip of uncut grass. In day-to-day use, we find we still like to use a trimmer for final details, but the mower helps reduce how much edging we have to do.

---

Six Height Positions: Customizing the Look and Health of Our Lawn

We find that adjustable cutting height is not only about looks; it is also about lawn health. The Westinghouse 40V mower offers 6 cutting height positions, ranging from around 1 inch to 3 inches.

We adjust our height based on:

• Season: Shorter in cooler seasons, slightly higher in hotter months.
• Grass type: Some grasses prefer a bit more height to stay healthy.
• Lawn condition: We raise it if our lawn is stressed, dry, or recovering.

The adjustment is straightforward, so we are not struggling with multiple levers on each wheel. We like that we can quickly change from a higher cut to a more manicured, lower finish when needed. A healthier lawn often starts with not cutting too low, and this mower gives us the flexibility to keep grass at a more protective height.

Mowing to the Deck Edge: Less Missed Grass, Less Extra Work

One feature we have come to appreciate is how close the mower cuts to the edge of the deck. Westinghouse highlights that it is made to mow right to the deck edge with minimal grass left uncut near borders.

This offers a few practical benefits:

• Less hand trimming along walkways and fences.
• Cleaner lines around flower beds and borders.
• Time saved after the main mowing pass.

While we still use a string trimmer for corners and awkward spots, we notice a reduction in the amount of touch-up work required. That adds up over the season, especially for those of us who are not looking to spend our whole weekend working on the yard.

---

Grass Collection and the 13-Gallon Rear Bag

We appreciate when a mower has a large enough grass bag to keep us from constantly stopping. The 13-gallon rear bag on this Westinghouse model hits a good balance between capacity and weight.

In our usage:

• On regular weekly cuts, the bag holds plenty before needing emptying.
• We notice more frequent stops only when we have let the grass grow longer than usual.
• The bag is not overly bulky or awkward to detach and reattach.

We also like the rear positioning of the bag. It keeps the mower compact and helps with balance. For those of us who prefer a neater yard with clippings collected rather than scattered, this bagging system works well.

---

Mulching Plug: Free, Natural Fertilizer for Our Lawn

Included with the mower is a mulching plug, which we can install when we want to mulch instead of bag. Mulching means the mower cuts the grass into fine clippings and redistributes them back onto the lawn, rather than sending them into the bag.

We often use mulching because:

• It returns nutrients to the soil, acting as a natural fertilizer.
• It reduces the number of bags of yard waste we have to deal with.
• It can help keep the lawn looking lush when done regularly.

We have found that mulching works best when:

• We mow regularly (so clippings are small).
• The grass is not too wet.
• We do not cut off more than one-third of the grass height at a time.

Having both bagging and mulching options gives us flexibility depending on the season and how much growth we are dealing with.

---

Handling and Maneuverability: Made to Move

Since this is a push mower (not self-propelled), how it feels to push is critical. Fortunately, the Westinghouse 40V model is relatively lightweight compared to many gas mowers, and the design makes it feel nimble.

We notice:

• Easy steering around obstacles such as trees, garden beds, and yard furniture.
• Manageable effort on flat or gently sloped lawns.
• More physical effort on steeper hills, which is expected for a non-self-propelled unit.

This mower suits us well if we prefer a lighter mower we can control precisely. Those of us with very hilly yards may wish for a self-propel feature, but for most suburban spaces, the weight and balance feel comfortable.

---

Noise Level: Kinder to Our Ears (and Our Neighbors)

One of the most immediate differences we feel when switching from gas to electric is the noise level. While the Westinghouse 40V lawn mower is not silent, it is noticeably quieter than a typical gas mower.

We appreciate this because:

• We feel more comfortable mowing earlier in the morning or later in the evening.
• Conversations near the mower are easier—no more shouting over the engine.
• We do not feel as fatigued from noise and vibration after finishing the lawn.

If we live in a neighborhood with close neighbors, a quieter electric mower like this can be a smart choice for keeping the peace while we keep the grass under control.

---

Setup and Storage: From Box to Backyard

Assembly and storage are often overlooked, but they can greatly affect how often we actually want to use our mower.

Assembly

From what we have experienced:

• Out of the box, the mower requires only minimal assembly—typically handle setup and attaching the bag if we plan to use it.
• The batteries arrive partially charged, but we should top them off fully before first use.
• Instructions are straightforward enough for anyone reasonably comfortable with basic tools.

We appreciate that we are not spending an entire afternoon assembling the mower when we would rather just cut the grass and move on with our day.

Storage

When it is time to put the mower away:

• The compact footprint makes it easier to store in a shed or garage.
• Being cordless and compact, we do not have to fight with cords, fuel, or large tanks.
• The lighter weight helps if we need to maneuver it around other equipment.

This ease of storage adds to the sense that this mower is a practical, everyday tool—not a bulky machine we dread dragging out.

---

Maintenance: Low Hassle Compared to Gas

One of our favorite aspects of cordless electric mowers is the simpler maintenance. With this Westinghouse model, there are still a few things we need to do, but far fewer than with a gas engine.

Typical maintenance includes:

• Keeping the blade sharp: Sharpen or replace as needed for clean cuts.
• Cleaning the deck: Remove built-up grass under the deck for better performance.
• Battery care: Store batteries in a cool, dry place and avoid complete discharges when possible.
• Checking for loose fasteners: Occasionally ensure none of the bolts or knobs have loosened.

We do not have to worry about:

• Oil changes
• Fuel stabilizers
• Carburetor issues
• Pull cords not starting

That alone reduces the time and stress of ownership for many of us.

---

Warranty and Support: Added Peace of Mind

Westinghouse includes a 2-year limited warranty with this mower, along with lifetime technical support backed by a nationwide service network. We find this reassuring, especially for those of us who are new to battery-powered outdoor equipment.

In our view, this matters for a few reasons:

• We feel more confident investing in a battery-powered mower knowing support is available.
• If something goes wrong in the early years, we have a clear path to service.
• Lifetime technical support means we can reach out with questions about battery care, usage tips, or troubleshooting.

Warranty coverage cannot prevent problems, but it does make them easier to live with when they occur.

Who This Mower Is Best For

Not every mower is right for every yard, so we like to be honest about who will get the most benefit.

We think the Westinghouse 40V 18 Inch Brushless Cordless Lawn Mower is best suited for:

• Small to medium lawns: The 25-minute runtime and 18-inch deck cover these efficiently when we mow consistently.
• Homeowners wanting less maintenance: Those of us tired of gas, oil, and tune-ups will appreciate the electric simplicity.
• People who value quieter operation: Ideal for neighborhood living and noise-sensitive environments.
• Those who like a neat, tailored lawn: With 6 height adjustments, mulching, and bagging, we can fine-tune results.
• Users with moderate physical strength: It is a push mower, so while not heavy like large gas models, it still requires some effort, especially on hills.

If we have a large, multi-acre yard or very heavy, thick grass that we routinely let grow tall, we might want a more powerful, self-propelled machine with longer runtime. But for typical suburban lots, this mower feels like a strong match.

Pros and Cons: Our Honest Take

To make things easier to compare, we like to list what we see as the main advantages and potential drawbacks:

Advantages

• Brushless 40V motor for efficient, quieter performance and longer life.
• Two 4.0Ah batteries included, so we are ready to mow without extra purchases.
• Realistic 25-minute runtime under load—enough for small to medium lawns.
• 18-inch cutting width balances coverage with maneuverability.
• Six height positions (1″–3″) to tailor cut and lawn health.
• Edge-to-edge mowing design helps reduce missed strips near edges.
• 13-gallon rear bag minimizes how often we have to stop and empty.
• Mulching plug included, allowing natural fertilizer from clippings.
• Lower maintenance than gas models—no oil changes or fuel issues.
• Quieter operation, better for us and our neighbors.
• 2-year limited warranty with lifetime technical support.

Potential Drawbacks

• Push-only (not self-propelled), which may be more tiring on slopes or large yards.
• Runtime of about 25 minutes may not be enough for larger properties in one go.
• 18-inch deck, while efficient, is smaller than some 20–21-inch mowers, meaning a few extra passes on bigger lawns.
• Battery charging time (not specified in detail) means planning ahead if we want to mow more after the pack is depleted.
• Not ideal for severely overgrown or very dense grass unless we take multiple passes or adjust our mowing height.

We feel the strengths heavily outweigh the trade-offs for typical residential users who mow regularly and want battery convenience.

Tips for Getting the Most Out of This Mower

Over time, we have found a few habits help us get better performance and longer life from a cordless mower like this one.

Mow Regularly

We try not to let the grass grow excessively between cuts. When we mow once a week or so:

• The mower does not work as hard.
• Cut quality improves.
• Mulching looks cleaner and more even.

Use the Right Cutting Height

We avoid cutting more than one-third of the grass height at once. For example:

• If our grass is 3 inches tall, we do not drop the mower to 1 inch in a single pass.
• We adjust gradually if we want a much shorter lawn over time.

This helps reduce stress on both the grass and the mower.

Maintain the Blade

A sharp blade makes a noticeable difference:

• Cleaner cuts for a healthier-looking lawn.
• Less strain on the motor and battery, preserving runtime.
• Reduced chance of tearing the grass tips, which can lead to browning.

We inspect and sharpen or replace the blade regularly, especially during the growing season.

Care for the Batteries

To keep the batteries performing well:

• We do not store them fully drained for long periods.
• We store them indoors or in a cool, dry place away from extreme heat or cold.
• We follow Westinghouse guidelines for charging cycles and storage.

Proper battery care is one of the biggest factors in long-term satisfaction with cordless tools.

Comparing Cordless Electric to Gas: Our Perspective

Since many of us have used gas mowers in the past, it helps to frame this Westinghouse model in that context.

With gas mowers, we are used to:

• More noise and vibration.
• More raw power and sometimes longer continuous run time.
• Regular maintenance: oil, filters, fuel, spark plugs.
• Smell of exhaust and risk of fuel spills.

With the Westinghouse 40V cordless mower, we gain:

• Cleaner operation with no fumes or fuel.
• Easier starting—just a battery and a button or lever, no pulling.
• Lower noise levels.
• Reduced maintenance workload.

We concede that gas mowers might still be better suited for very large, demanding properties, but for many everyday homeowners, the trade-off strongly favors a cordless option like this.

---

Environmental and Comfort Benefits

We also consider the environmental and comfort aspects. While battery-powered tools are not completely without environmental cost, they do provide meaningful benefits over gas:

• No direct emissions from the mower while we are cutting.
• Less noise pollution, especially in dense neighborhoods.
• No handling of gasoline, which can spill and release vapors.

From a comfort perspective, we appreciate not breathing in exhaust or dealing with oil stains in the garage. This makes mowing feel a bit more like a simple household task and less like operating a small engine.
