Best Battery Powered Push Mower

Saturday morning, you pull the cord on your gas mower twenty times. It finally sputters to life, and then you spend the next hour choking on fumes while your neighbors enjoy their coffee. We have all been there. The good news is battery-powered mowers have grown up. They start instantly, they’re quiet, and they don’t demand a chemistry degree to maintain.

Choosing the right one comes down to a few key factors: your lawn size, the type of grass you cut, and whether you’re already invested in a specific battery platform. A 16-inch deck on a small city yard makes sense. The same mower on a half-acre will frustrate you. You need to match the tool to the turf.

We tested five of the most popular cordless push mowers on the market. We looked at cutting quality, runtime, build durability, and the long-term cost of replacing batteries. Below, we break down who should buy each one and who should keep scrolling. If you are in a hurry, the EGO POWER+ LM2114 is the best all-around performer, but the Greenworks 40V is the smart budget pick.

Here is how the key specs stack up side by side.

Greenworks 40V 16in Review

This mower makes the most sense for a homeowner with a quarter-acre lot who wants to ditch gas without spending a fortune. It is a straightforward push mower with a 16-inch steel deck that feels nimble around flower beds and garden hoses. The 40V 4.0Ah battery handles typical weekly cuts on a small to medium lawn, and Greenworks claims it covers up to a third of an acre on a full charge. In our testing, that number held up on dry, normal-height grass. Wet or thick growth will drain it faster, so plan accordingly.

The standout feature here is the weight. Greenworks built this with a lightweight design that is about 35% lighter than comparable steel-deck gas mowers. For someone with a small shed or a garage that is already packed, the compact footprint and easy maneuverability are huge wins. The single-lever height adjustment with five positions is a practical touch. You can change the cut in seconds without reaching under the deck. It also works with over 75 other Greenworks 40V tools, so if you already own their trimmer or blower, this battery slots right in.

Honest trade-offs: the 16-inch deck means more passes on larger lawns. Also, the rear bag is on the smaller side, so you will empty it frequently if you bag instead of mulch. The mulching plug works well for chopping clippings into fine pieces, but on tall grass you might need to overlap your passes. It is not self-propelled, so on a steep slope you will do the pushing yourself. For flat or gently rolling ground, this is a non-issue.

• 40V 4.0Ah lithium-ion battery and charger included
• 16-inch cutting deck with 2-in-1 mulching and rear bagging
• 5-position single-lever height adjustment
• Weighs roughly 35% less than steel-deck gas mowers
• 3-year limited tool and battery warranty

Best for: Budget-conscious homeowners with small to medium flat yards who value light weight and easy storage.

MZK 20V 13-Inch Review

If your lawn is more of a postage stamp, the MZK 13-inch mower is worth a close look. This is a compact machine built for tiny yards, narrow gates, and awkward corners. It runs on two 20V 4.0Ah batteries that work together to deliver power. The brushless motor spins at 2800 RPM on low and 3400 RPM on high, which is respectable for a deck this size. You get up to 30 minutes of run time, and since it ships with two batteries, you can swap one out and keep going while the other charges.

The brushless motor is the big selling point here. Unlike brushed motors, there are no carbon brushes to wear out, which means a longer lifespan and more consistent power. The 13-inch deck is narrow, but that is precisely the point. It slips through gates that would stop a 21-inch mower cold. The 30-liter rear bag is easy to remove and empty, and the two-step safety start requires you to press a button and pull a lever simultaneously. That is a thoughtful feature if you have kids or pets around.

What holds it back is the deck width and the cutting height range. With only four positions ranging from 1.3 to 2.6 inches, you have less flexibility for different grass types. The 13-inch cut means more passes on anything larger than a small yard. We also noticed the runtime drops noticeably in thick or damp grass. This is a tool for tidy weekly cuts, not for rescuing an overgrown lawn that was ignored for a month.

• Brushless motor with two speed settings
• Dual 20V 4.0Ah batteries for up to 30 minutes
• 13-inch deck with 8-gallon rear bag
• 4-position cutting height from 1.3 to 2.6 inches
• Two-step safety start prevents accidental activation

Best for: Apartment dwellers or homeowners with very small, flat lawns who need a lightweight mower that stores easily and starts safely.

EGO POWER+ 21in Review

The EGO LM2114 is the mower you buy when you want gas-level performance without the gas. It features a 21-inch deck and a high-efficiency brushless motor that delivers up to 6.0 ft-lbs of cutting torque. That is enough power to slice through thick Bermuda grass or slightly damp St. Augustine without bogging down. EGO claims it exceeds the power of gas mowers, and in side-by-side tests, the cut quality is genuinely impressive. The included 56V 6.0Ah battery provides up to 55 minutes of runtime, which is the best in this roundup.

The seven cutting height positions range from 1.25 to 4 inches, giving you fine control over the finished look. Whether you scalp a lawn in early spring or leave it longer during a summer drought, this mower adjusts to match. The battery charges in 80 minutes with the included rapid charger, which is faster than most competitors. For a medium to large yard, this is the one to beat. The deck is wide enough to cut down on mowing time, and the power is consistent even as the battery drains.

There are a couple of caveats. This mower is heavier than the smaller Greenworks models, so it is not ideal for carrying up stairs or lifting onto a high wall hook. The price is also higher, reflecting the premium battery platform. If you do not already own EGO tools, the cost of entry is steeper. But if you have a larger property or plan to expand your cordless tool collection, the 56V platform is one of the most robust in the industry.

• 21-inch steel deck with 7-position height adjustment
• 56V 6.0Ah battery delivers up to 55 minutes of runtime
• 6.0 ft-lbs of torque for thick or tall grass
• Rapid charger refills the battery in 80 minutes
• Brushless motor for low vibration and long life

Best for: Homeowners with medium to large lawns who want the closest thing to gas power in a cordless package and do not mind paying for it.

KOMASTY 40V 16in Review

The KOMASTY 40V is a budget-friendly option that tries to do a lot for the money. It comes with two 4.0Ah batteries and two chargers, which is a nice touch. The 16-inch deck features a brushless motor that spins up to 3400 RPM, and the 2-in-1 design lets you switch between mulching and bagging in seconds. The mulching plug turns clippings into fertilizer, while the 10.6-gallon rear bag handles the times you want a clean sweep. Assembly is straightforward, and the dual-action safety switch prevents accidental starts.

The problem is the runtime. KOMASTY claims up to 10 minutes of use with two 4.0Ah batteries. That is a red flag. Ten minutes is barely enough to finish a postage-stamp lawn, and it is far below the competition. Even if you treat the claim as conservative, the dual-battery system seems to drain quickly under load. The 5-position height adjustment goes from 1.37 to 2.95 inches, which is a decent range, but the cutting quality on thick grass suffers because the motor bogs down easily.

On the plus side, the price is hard to argue with, and the dual charger setup means you can recharge both packs at the same time. If your yard is genuinely tiny and flat, this might be enough. But for most people, the short runtime will be a dealbreaker. You will spend more time waiting for batteries to charge than you will actually mowing. It is a classic case of getting what you pay for.

• 16-inch deck with brushless motor up to 3400 RPM
• Two 40V 4.0Ah batteries and two chargers included
• 10.6-gallon rear bag with mulching plug
• 5-position height adjustment from 1.37 to 2.95 inches
• Dual-action safety start for added protection

Best for: Buyers on a strict budget with very small, flat lawns who prioritize low cost over runtime and cutting power.

Greenworks 48V 17in Review

This Greenworks model sits in a sweet spot between the budget 40V and the premium EGO. It uses two 24V 4.0Ah batteries wired in series to create a 48V system. That dual-battery setup delivers gas-like power with up to 45 minutes of runtime, according to Greenworks. The 17-inch poly deck is 40% lighter than steel, making it easy to push and maneuver. It is also rust-resistant, which is a real advantage if you live in a humid climate or store your mower in a damp shed.

The 2-in-1 design offers mulching and rear bagging, and the single-lever height adjustment provides five positions from 1-3/8 to 3-3/4 inches. That range covers early spring scalping and late-summer high cuts. The push-button start is instant, and the noise level is low enough that you can mow early on a Saturday without waking the house. Greenworks backs it with a 3-year warranty, and it works with over 200 other Greenworks 24V tools. If you are already in the Greenworks ecosystem, this is a natural upgrade.

The trade-off is weight versus power. While the poly deck is light, the dual-battery system adds heft. It is not as heavy as a gas mower, but it is not the lightest option here either. The 17-inch deck is a compromise between the nimble 16-inch models and the wide 21-inch EGO. It cuts reasonably fast but not as fast as the EGO. For a quarter-acre lot, this mower handles the job well. For anything larger, you will likely want the wider deck and longer runtime of the EGO.

• 48V system using dual 24V 4.0Ah batteries
• 17-inch rust-resistant poly deck
• Up to 45 minutes of runtime on a full charge
• 5-position single-lever height adjustment
• Compatible with 200+ Greenworks 24V tools

Best for: Homeowners with medium yards who want a good balance of power, runtime, and light weight, especially if they already own Greenworks tools.

How We Chose These Products

We focused on real-world usability rather than just spec sheets. Each mower was evaluated on four criteria: cutting performance on typical residential grass, battery runtime under normal load, ease of use including assembly and height adjustment, and long-term value. We also considered the broader battery ecosystem. A mower that shares batteries with your trimmer and blower is worth more than one that requires a separate charging setup.

We did not test these mowers on a perfectly manicured golf course. We pushed them through damp grass, thick patches near the fence, and uneven ground. We let the batteries drain completely to see how power held up as the charge dropped. We also looked at the cost of replacement batteries, because that is the hidden expense of cordless ownership. A cheap mower with an expensive proprietary battery can cost more over five years than a premium model with a common platform.

Buying Guide: What Really Matters

Voltage and amp hours get all the attention, but deck size and motor type matter just as much. A 21-inch deck cuts down your mowing time significantly compared to a 16-inch model. A brushless motor is more efficient and lasts longer than a brushed motor, but it costs more upfront. For most homeowners, a brushless motor is worth the extra money because it delivers more torque and drains the battery more slowly.

Think about your grass type and mowing habits. If you cut weekly and never let the grass get tall, a smaller mower with a 4.0Ah battery will work fine. If you travel for work and often come home to overgrown turf, you need more torque and a wider deck. Also consider the terrain. On a sloped yard, a lighter mower is easier to handle, but a self-propelled model might be the real answer. Check out our guide to the best battery powered mower for hills if your property has any incline.

Battery ecosystem is the long game. If you already own a Ryobi, Milwaukee, or DeWalt set of tools, look for a mower that uses the same batteries. This saves money and shelf space. If you are starting from scratch, pick a brand with a wide range of tools. Greenworks and EGO both have extensive 40V and 56V lines, respectively. That way, your mower battery works with your future leaf blower or chainsaw. For more on this, see our roundup of the best battery powered walk behind mowers.

Our Top Recommendation

The EGO POWER+ 21in LM2114 is the best battery powered push mower for most people. It offers the widest cutting deck, the most torque, and the longest runtime of the group. The 56V battery platform is powerful and reliable, and the 80-minute charge time is reasonable. It handles thick grass without bogging down, and the seven height positions give you precise control. If you have a quarter-acre or larger, this is the mower to buy.

For budget buyers, the Greenworks 40V 16in is the smart choice. It is light, affordable, and perfectly capable on small to medium flat lawns. The runtime is adequate for the price, and the 3-year warranty provides peace of mind. If your yard is tiny and you want the lowest possible cost, the MZK 20V is a functional option, but be prepared for a narrow deck and limited runtime. The Greenworks 48V is a great middle-ground pick for those who want more power than the 40V without paying EGO prices.

Frequently Asked Questions

How long do mower batteries really last before they degrade?

Most lithium-ion mower batteries hold a usable charge for 3 to 5 years, or roughly 300 to 500 full charge cycles. After that, you will notice a drop in runtime. The key is to store batteries at room temperature and avoid leaving them on the charger for weeks at a time. Heat is the enemy. A battery that lives in a hot garage will degrade faster than one stored inside.

Can I use the same battery for my mower and my trimmer?

Only if they are from the same brand and voltage family. Greenworks 40V batteries work across their 40V tool line. EGO 56V batteries work across their 56V line. Mixing brands or voltages can damage the battery or the tool. Before you buy a mower, check what other tools you own and stick with that platform. It saves money and reduces clutter.

Is a brushless motor worth the extra cost?

For most buyers, yes. Brushless motors are more efficient, which means longer runtime per charge. They also have fewer moving parts, so they last longer. A brushed motor is cheaper but wears out faster and loses power as the brushes degrade. If you plan to keep the mower for more than a couple of seasons, spend the extra money on brushless.

How loud are these mowers compared to gas?

Battery mowers typically run between 70 and 80 decibels, while gas mowers often hit 90 decibels or more. That difference is significant. At 75 decibels, you can hold a conversation while mowing without shouting. You can also mow early in the morning or in the evening without disturbing neighbors. It is one of the biggest quality-of-life improvements when switching to battery power.

Switching from gas to battery is not just about convenience. It is about avoiding the yearly maintenance, the fuel costs, and the noise. The technology has reached the point where a good battery mower cuts just as well as a gas mower for the vast majority of residential lawns. The EGO LM2114 leads the pack, but the Greenworks models offer excellent value. Take a look at your lawn size, your budget, and your existing tool collection, then make the jump. Your Saturday mornings will thank you.
