SKIL 40V Brushless 20″ Push Mower Kit Review

Have we ever wished mowing our lawn felt less like a chore and more like a quick, satisfying task we can check off our list without smelling like gas afterward?

Why We Considered the SKIL 40V Brushless 20″ Push Mower Kit

When we looked at cordless mowers, we wanted something powerful enough to replace a gas mower, but without the fuss of pull cords, tune-ups, and fuel mixtures. The SKIL 40V Brushless 20″ Push Mower Kit (model PM4910-15) immediately stood out because it balances power, convenience, and battery tech in a way that feels genuinely practical for everyday homeowners.

We also noticed that this kit is truly ready to go out of the box: mower, 6.0Ah battery, and a 150W Auto PWR JUMP charger are all included, so we are not hunting for extra pieces just to get started.

First Impressions and Unboxing Experience

Our first reaction when taking this mower out of the box is that it feels solid without being too heavy. The design is clean and modern, with a 20-inch steel deck that signals we are dealing with a serious tool, not a toy.

We also appreciate that SKIL included both a mulch plug and a grass bag in the kit. Right away, we know we can choose our preferred cutting style without needing extra purchases.

What Comes in the Box

It is always reassuring when a kit truly means “kit.” With the SKIL 40V Brushless 20″ Push Mower, everything essential is included.

• SKIL 40V Brushless 20″ Push Mower (PM4910-15)
• PWR CORE 40 6.0Ah lithium-ion battery
• Auto PWR JUMP 150W charger
• Mulch plug
• Grass collection bag
• User manual and safety materials

From a practical standpoint, this means we only need to charge the battery and we are ready to mow. No additional cords, no oil, no fuel, no spark plugs.

Design and Build Quality

The mower feels well-engineered, blending a rugged deck with a thoughtful handle and a compact footprint when folded. The telescoping handle and folding design show that SKIL clearly thought about our garage or shed space, not just the cutting performance.

We especially like that the controls feel intuitive: a simple push-button start and safety bar setup make operation straightforward, even for someone using a cordless mower for the first time.

Power and Performance: Brushless Motor and 40V System

The heart of this mower is the digital brushless motor powered by SKIL’s 40V platform. Brushless motors are known for efficiency, lower maintenance, and more consistent power output compared to brushed motors.

What this means for us while cutting is fewer bog-down moments and a smoother experience across variable grass heights and densities, as long as we stay realistic about it being a push mower, not a commercial zero-turn.

Digital Brushless Motor Advantages

The digital brushless motor in this mower offers a noticeable improvement over older cordless designs. It delivers better power per watt, which translates into more cutting time from each battery charge.

We also benefit from reduced mechanical wear. Because there are fewer friction-based components, the motor runs cooler, quieter, and with less maintenance over the lifetime of the tool.

Comparing to a Traditional Gas Mower

If we are used to yanking a pull cord and smelling gas fumes, this mower gives us a very different experience. We simply press a button, pull the bail bar, and we are cutting.

Here is how the SKIL 40V Brushless 20″ Push Mower typically compares to a traditional residential gas mower in everyday use:

Feature	SKIL 40V Brushless 20″ Push Mower	Typical Gas Push Mower
Starting	Push-button	Pull cord
Fuel / Power	40V lithium battery (6.0Ah)	Gasoline
Noise Level	Noticeably quieter	Louder engine noise
Maintenance	Low (sharpen blade, clean deck)	Higher (oil changes, fuel issues)
Emissions	Zero at point of use	Direct exhaust emissions
Storage	Vertical folding handle	Typically horizontal only
Weight & Handling	Moderate and maneuverable	Varies, often heavier

For most homeowners with small to medium lawns, the SKIL kit offers enough performance to replace gas without much compromise, especially if we value quiet operation and low maintenance.

Battery and Charger: Runtime, Longevity, and Charging Speed

Battery tech is where this mower distinguishes itself. The PWR CORE 40 6.0Ah battery uses a unique cooling wrap around each cell, which SKIL claims helps deliver 25% longer runtime and up to 2x battery life compared to typical lithium packs without such cooling.

For us, that means more mowing on a single charge and better durability over the long term, reducing the odds of the battery feeling “tired” after only a couple of seasons.

Understanding the 6.0Ah PWR CORE 40 Battery

A 6.0Ah (amp-hour) battery at 40V provides substantial energy capacity. In real-world terms, we can generally expect to mow most small to medium suburban yards (up to roughly 1/3 to 1/2 an acre depending on grass density and conditions) on a single charge.

Of course, actual runtime will vary with:

• Grass height and thickness
• Terrain (flat vs. hilly)
• Whether we are bagging or mulching
• How fast we walk and push

Still, the cooling technology around each cell helps the battery stay at a more optimal temperature, which tends to support more efficient energy delivery and longer component life.

Auto PWR JUMP 150W Charger

The included Auto PWR JUMP charger is designed to get us from “dead” to “working” quickly. SKIL’s PWR JUMP feature, on compatible systems, typically provides enough charge for a partial mow in a short time, which can be extremely helpful if we run out of power mid-lawn.

We also appreciate that the charger is part of a broader ecosystem. If we already own or plan to own other SKIL 40V tools (like blowers, trimmers, or chainsaws), the battery and charger can be shared among them, making the whole system more cost-effective.

Mowing Experience: Ease of Use and Comfort

This mower is built with user comfort in mind, especially for those of us who might not enjoy wrestling with heavy equipment. The push-button start, single-lever height adjustment, and folding handle simplify interactions that can often be annoying on older designs.

We notice that once we get used to the mower’s rhythm, cutting becomes a bit more effortless and less stressful, partially because there is no engine roar and no hot exhaust.

Push-Button Start and Controls

To start the mower, we typically:

1. Insert the charged battery
2. Press the power button
3. Engage the safety/bail bar

This process is far quicker and more pleasant than repeatedly pulling a starter cord and hoping the engine catches. It also makes it less intimidating for family members who might be new to mowing.

Stopping is simple too: we release the bar and the mower shuts off. There is no need to worry about choking the engine or turning off a fuel valve.

Handling and Maneuverability

With its 20-inch deck, this mower strikes a nice balance between coverage and maneuverability. It is wide enough to make efficient passes in open areas yet narrow enough to handle around trees, flowerbeds, and landscaping features.

The push design means we provide the propulsion, but the weight is manageable for most users, and the balance between front and rear wheels feels stable. On smooth, moderately flat lawns, it handles nicely, and the cordless format means we are not dragging a cord behind us.

Cutting Performance and Grass Management

We generally judge a mower on how cleanly and consistently it cuts, as well as how it deals with clippings. The SKIL 40V Brushless 20″ handles most typical residential mowing tasks well, especially when we mow regularly rather than waiting until the grass is ankle-high.

The steel deck and sharp blade produce a neat cut, and the 2-in-1 bagging or mulching system gives us flexibility in how we handle clippings.

20″ Cutting Deck: Coverage vs. Precision

A 20-inch cutting width is a sweet spot for many homeowners. Each pass covers a decent amount of ground without sacrificing maneuverability in tighter spaces.

For us, that means fewer passes on an open lawn but still enough precision to cut around landscaping elements. It is not as wide as a 21″ or 22″ commercial-style mower, but it feels well-matched to the battery runtime and residential use.

Single-Lever Deck Height Adjustment (Seven Settings)

The single-lever deck height adjuster is one of those user-friendly features that we really only appreciate after experiencing a mower without it. Instead of adjusting each wheel separately, we just move one lever to choose from seven different height settings.

This allows us to:

• Keep grass longer in hot, dry weather to promote healthier roots
• Cut shorter during cooler seasons if desired
• Adjust quickly if we encounter uneven spots

Having this range of heights helps us manage different lawn types and seasonal conditions more easily than a limited or awkward height system.

2-in-1: Bagging or Mulching

The kit includes both a mulch plug and a grass catcher bag, giving us two primary modes:

1. Mulching – The clamp-on mulch plug blocks the rear discharge, forcing clippings to be chopped into smaller pieces and dropped back into the lawn. This can help return nutrients to the soil and reduce yard waste.
2. Bagging – Installing the grass bag allows clippings to be collected, which is useful when the grass is very long, when we want a particularly tidy look, or when we want to avoid leaving clippings on hard surfaces.

We like having both options because it means we can adapt our mowing style across the season. For example, we might mulch most of the time but bag during the first cut of the year or after heavy rain when the grass is especially thick.

Storage and Space-Saving Design

When mowing is done, the mower does not need to dominate our shed or garage. One of the most thoughtful aspects of this model is the fully foldable, telescoping handle that enables vertical storage.

We simply fold the handle down, stand the mower up, and it occupies a much smaller footprint.

Foldable, Telescoping Handle

The handle design contributes to both comfort during operation and convenience during storage. We can adjust it to a comfortable height for different users, helping reduce strain on backs and shoulders.

After mowing, we release a couple of points on the handle and fold it down. This process feels intuitive and does not require tools. It is the kind of detail that makes it easier to own and store a mower in tight spaces.

Vertical Storage Benefits

Storing the mower vertically has clear advantages:

• Frees up floor space around cars, tools, and bikes
• Keeps the mower more out of the way, especially in narrow garages
• Makes it easier to keep our space tidy and organized

For those of us with limited storage, this feature is a real asset. Instead of designing our garage around the mower, the mower adapts to our space.

Weather Resistance and Durability

Mowers live in a tough environment: heat, moisture, dust, and occasional bumps and scrapes. The SKIL 40V Brushless 20″ includes IPX4 weather resistance, which helps protect it from splashing water and light exposure to the elements.

We still should not leave it out in a rainstorm, but we gain peace of mind that it will tolerate some wet conditions or accidental splashes.

IPX4 Weather Resistance Explained

IPX4 means the mower is resistant to water splashes from any direction. In real terms, this can help with:

• Light rain or mist that starts while we are finishing up
• Moisture from slightly damp grass
• Occasional splashes from cleaning or nearby water sources

We still want to avoid intentional soaking or pressure-washing the mower, but IPX4 is a meaningful step beyond non-rated tools that may not handle moisture as well.

Build Materials and Long-Term Use

The combination of a metal deck, robust plastic components, and a brushless motor makes this mower feel like it is designed for multi-season use. While every tool depends on proper care, it is reassuring to know that the core components are not flimsy.

We also appreciate that fewer mechanical engine parts (like carburetors and spark plugs) means fewer maintenance points that can fail or gum up over time.

Noise Level and Neighborhood Friendliness

One of the biggest benefits we notice right away with a cordless mower is the reduction in noise. Although it is not silent, it is much quieter than a gas engine, especially when idling and in normal cutting.

This makes early-morning or evening mowing far more considerate of neighbors and family members who might be inside or nearby.

Quieter Operation in Everyday Use

We can usually carry on a conversation at normal volume while near the mower, which is nearly impossible with most gas models. That reduction in sound levels also makes mowing feel less stressful and fatiguing.

For those of us who like to mow on weekend mornings or after work, this quieter operation is a big lifestyle improvement, not just a technical specification.

Comfort Over Longer Sessions

Reduced noise, fewer vibrations from a gas engine, and easy controls all contribute to a more comfortable experience if we are mowing for a full session or doing multiple passes.

We also do not have to worry about exhaust fumes or lingering fuel smells on our clothes, which can make yardwork more appealing for those of us who are sensitive to odors or prefer a cleaner experience.

Ease of Maintenance and Care

A mower that requires constant tinkering tends to get neglected. The SKIL 40V Brushless 20″ is on the other end of that spectrum, where routine care is straightforward and mostly limited to cleaning and blade maintenance.

We do not have to buy fuel, change oil, or store gas cans, which simplifies our overall lawn care routine.

Routine Tasks We Should Expect

To keep this mower in good shape, we will typically:

• Brush or wash off caked-on grass from the deck (once the battery is removed and blades are stopped)
• Check and sharpen or replace the blade as needed
• Inspect the underside for debris or damage
• Store the battery properly when not in use (in a cool, dry place)

These tasks are simple enough that most homeowners can manage them without extra equipment or expertise.

Long-Term Battery Care

Because the battery is such a key component, taking care of it is essential:

• Avoid fully draining it repeatedly; partial discharge and recharge is generally fine
• Do not leave it in extreme heat (like a hot car) for extended periods
• Store it indoors in moderate temperatures when not in use for long periods

Following basic lithium-ion best practices can help us take full advantage of SKIL’s claim of extended battery life and runtime.

Who This Mower Is Best For

Not every mower is right for every situation, so it helps to be honest about our lawn size, terrain, and expectations. The SKIL 40V Brushless 20″ Push Mower Kit is particularly well suited for a certain group of users.

We find this mower is ideal for homeowners who value convenience, quiet operation, and low maintenance more than raw, heavy-duty power for oversized properties.

Ideal Yard and User Profile

This mower is best for:

• Small to medium suburban yards
• Mostly flat lawns or gentle slopes
• Homeowners planning regular weekly or bi-weekly mowing
• Users who want cordless convenience with no fuel storage

It is also a great fit for those of us who already own or plan to own other SKIL 40V tools because the battery platform can be shared, stretching value across multiple tools.

Situations Where It May Not Be the Best Fit

We might want to reconsider if:

• Our lawn is very large (for example, close to or over an acre) and we do not plan to invest in additional batteries
• We have extremely thick, neglected grass on a regular basis and prefer to mow infrequently at very low cutting heights
• We require self-propelled assistance due to steep hills or physical limitations

In those cases, either a self-propelled cordless mower with multiple batteries or a larger gas mower might align better with our needs.

Advantages and Disadvantages at a Glance

To make our decision easier, it helps to summarize the main pros and cons in one place. This allows us to quickly see whether the strengths align with what we value most in a mower.

Aspect	Advantages	Disadvantages / Trade-Offs
Power	Brushless 40V motor with good cutting performance	Not as powerful as large commercial gas units
Battery	6.0Ah pack with cooling tech for longer runtime and life	Runtime still finite; large lawns may require multiple charges
Starting	Push-button start, very easy and fast	Requires charged battery (cannot just add more gas and go)
Noise	Quieter than gas, more neighbor-friendly	Still produces some noise (it is not silent)
Maintenance	Very low: no oil changes, no fuel system	Blade still requires periodic sharpening or replacement
Storage	Foldable, vertical storage saves space	Still requires some dedicated floor area
Features	7-position single-lever height adjustment, 2-in-1 bag/mulch	No side discharge option for those who prefer it
Durability	IPX4 weather resistance, brushless design, sturdy deck	Not intended for heavy commercial or constant all-day use

By weighing these factors, we can see how well this mower fits our current situation and whether a cordless system matches our long-term yard care plans.

Practical Tips for Getting the Most from This Mower

To really enjoy this mower and make it serve us well for years, a few practical habits go a long way. These are not complicated, but they significantly improve the experience.

We can treat them as simple guidelines rather than strict rules.

Mowing Strategy and Battery Management

To maximize runtime and cut quality:

• Mow regularly so we are cutting smaller amounts of grass each time
• Avoid letting grass get excessively tall and thick between cuts
• Start with the battery fully charged before each session
• If we have a larger yard, consider planning breaks around charging times or investing in a second battery

We may also notice that mulching in very tall or wet grass makes the motor work harder. In those situations, bagging or raising the deck height a notch can reduce strain.

Cleaning and Blade Care

After finishing, once the mower is off and the battery is removed:

• Knock off loose clippings from the deck, wheels, and bag
• Periodically check the underside for built-up residue and gently remove it
• Inspect the blade every few uses; a sharp blade improves cut quality and reduces power draw

Keeping the blade in good condition is one of the easiest ways to extend battery runtime and ensure a healthier-looking lawn.

Environmental and Lifestyle Considerations

Beyond simple lawn cutting, this mower fits into a broader shift many of us are making toward less noisy, less polluting home tools. For those who are environmentally conscious or just prefer cleaner, quieter equipment, this mower aligns with that mindset.

We also notice the difference in how we feel after mowing when there is no exhaust cloud or gas smell involved.

Reduced Emissions at Home

Using a battery-powered mower eliminates direct exhaust emissions at the point of use. While electricity generation may still involve emissions depending on the grid, we are at least not burning fuel right in our yard.

For many of us, this matters both from a health perspective and a personal values standpoint. It is reassuring to maintain our property without constantly breathing in combustion fumes.

Comfort and Convenience in Everyday Life

Having a mower that starts reliably, stores neatly, and does not require gas runs is a lifestyle improvement. We can more easily fit yardwork into busy schedules because we do not have to budget time for maintenance tasks like engine troubleshooting or fuel system cleaning.

This convenience also makes it more likely that we will keep up with regular mowing, which in turn keeps the lawn healthier and more attractive.

Final Thoughts: Is the SKIL 40V Brushless 20″ Push Mower Kit Right for Us?

Overall, the SKIL 40V Brushless 20″ Push Mower Kit (PM4910-15) offers a very appealing blend of features for homeowners who want a reliable cordless solution. With its digital brushless motor, 6.0Ah PWR CORE 40 battery, Auto PWR JUMP charger, and thoughtful design elements like single-lever height adjustment and vertical storage, it hits a sweet spot between power and practicality.

If our lawn is small to medium in size, reasonably well-maintained, and mostly flat, this mower can serve as a full replacement for a traditional gas model, while being quieter, cleaner, and easier to live with. We get flexible cutting options (bagging or mulching), practical weather resistance, and a mower that fits more naturally into a modern, low-maintenance household.

For larger or more demanding properties, we might need extra batteries or a different style of mower. But for many of us, especially in typical suburban settings, this kit delivers a strong combination of performance and convenience that makes mowing feel less like a chore and more like a quick task we can handle on our own schedule, without the usual gas-related hassles.
