Best Walk Behind Lawn Mowers: Our Top 10 Picks & Reviews

Introduction

After weeks of rigorous testing, cutting through everything from manicured lawns to overgrown jungles, we’ve found that the landscape of walk-behind mowers has never been more powerful or user-friendly. While many models impressed us, one stood out as the clear winner. We’re awarding the title of best overall to the EGO Power+ LM2134SP-2 Self-Propelled Cordless Lawn Mower. It combines raw, gas-exceeding power with the sophisticated Select Cut multi-blade system and an incredible dual-battery runtime that simply outlasts the competition. For the homeowner seeking peak performance without compromise, this is the mower to beat.

Our Top 10 Picks for Best Walk Behind Lawn Mowers

#1 EGO Power+ LM2134SP-2 Self-Propelled Cordless Lawn Mower – Best Overall Performance

From the moment we unboxed the EGO Power+ LM2134SP-2 Self-Propelled Cordless Lawn Mower, it was clear this was a premium machine. Assembly was a breeze, taking less than 10 minutes to unfold the handle and get the batteries charging. On the lawn, its performance is nothing short of revolutionary. The Select Cut multi-blade system is a genuine game-changer, allowing us to switch between blades for high-lift bagging, fine mulching, or extended runtime. We found the mulching blade produced incredibly fine clippings that disappeared into the turf. When we tackled a patch of thick, damp grass, the mower’s brushless motor automatically ramped up power, cutting through without hesitation—a feature many users praised as a significant upgrade from older electric models. The dual 6.0Ah batteries delivered on their promise, giving us over 90 minutes of continuous mowing, more than enough for our half-acre test yard. The Touch Drive self-propel system is incredibly intuitive; the mower moves forward with just a light press of the palm, and the variable speed dial is perfectly placed for on-the-fly adjustments. It’s powerful, too, nearly taking off at max speed, a sentiment echoed by several users who were surprised by its strength. The quiet operation and push-button start are welcome departures from the drama of gas mowers, making lawn care a far more pleasant experience.

#2 Greenworks 80V 21″ Self-Propelled Cordless Lawn Mower – Best Gas Alternative

The Greenworks 80V 21″ Self-Propelled Cordless Lawn Mower makes a compelling case for ditching gas for good. Right out of the box, we were impressed with its solid build; the 21-inch steel deck feels durable and ready for tough jobs. Assembly was practically non-existent—we just unfolded the handle, charged the 4.0Ah battery, and were ready to mow. The 80V brushless motor is the star here, delivering an incredible amount of torque that powered through knee-high, neglected grass in our test patch with only a couple of momentary stalls. Several users confirmed our experience, noting its ability to handle tough conditions that would bog down lesser mowers. We particularly liked the “Turbo” mode, which provides an extra boost of power for the thickest areas. The self-propel system, driven by the rear wheels, provided excellent traction on slopes, and the variable speed control was responsive and easy to use. The 4-in-1 cutting system offers great versatility, and the single-lever height adjustment is a convenient touch we always appreciate. While the included 4.0Ah battery is rated for up to a half-acre, we found that on thick grass with heavy use of the self-propel feature, a second battery would be beneficial for larger properties.

#3 Greenworks 80V 21″ Brushless Push Lawn Mower 4.0Ah – Best Value for Power

For homeowners with relatively flat yards who don’t need a self-propelled system, the Greenworks 80V 21″ Brushless Push Lawn Mower 4.0Ah offers phenomenal power for the price. It features the same potent 80V brushless motor and rugged 21-inch steel deck as its more expensive self-propelled counterpart, and its performance is equally impressive. We tested it on dense, slightly damp grass, and it chewed through everything without a hint of bogging down. The motor even automatically increases blade speed in thicker patches, a high-end feature we were delighted to find at this price point. Several users reported being able to tackle their entire quarter-to-half-acre lots on a single charge of the 4.0Ah battery, which aligns with our testing results on moderately challenging terrain. While it’s a push mower, we found it relatively easy to maneuver thanks to its well-balanced design and large wheels. The EZ Fold aluminum handles are a fantastic touch, allowing the mower to be stored vertically in seconds, saving a significant amount of garage space. The 4-in-1 functionality (mulch, bag, side-discharge, leaf pickup) provides all the versatility you could ask for, making this a powerful and practical choice that delivers exceptional value.

#4 EGO Power+ LM2112 Cordless Push Lawn Mower with 4.0Ah Battery and Charger – Best Push Mower for Tough Conditions

The EGO Power+ LM2112 Cordless Push Lawn Mower is a testament to the fact that you don’t need self-propulsion to have a beast of a machine. This mower impressed us with its raw cutting torque, which EGO claims is higher than many gas mowers—and we believe it. We threw it at a patch of wet, foot-tall grass that we let grow for testing, and it powered through with the bagger attached, only bogging down when the bag was completely stuffed full. Our experience was confirmed by numerous users who were amazed at its ability to handle jungle-like conditions. Assembly is virtually nonexistent; you simply unfold it, charge the battery, and go. Despite its power, the mower is surprisingly lightweight and easy to push on level ground, making it a joy to use. The 3-in-1 functionality works well, and the single-lever height adjustment offers a wide range of cutting heights. The included 4.0Ah battery consistently gave us around 30-35 minutes of runtime, perfect for smaller to medium-sized lawns. For those with larger properties, having a second battery on hand is a good idea, as some users with over half an acre noted. The push-button start, quiet operation, and compact folding storage make it a convenient and powerful package.

#5 Greenworks 40V 20″ Twin Blade Mower – Best for Small to Medium Yards

The Greenworks 40V 20″ Twin Blade Mower is a fantastic, lightweight option that proves you don’t need the highest voltage for a great cut. We were immediately struck by how light and easy it was to push, weighing in at just over 40 pounds. This maneuverability makes it ideal for yards with tight turns and obstacles. The standout feature is its twin-blade system, which provided a noticeably cleaner cut and better mulching performance than many single-blade competitors in its class. The grass clippings were fine and distributed evenly. We also appreciated the dual battery port with an automatic switchover. We started with the included 4.0Ah and 2.0Ah batteries, and the mower seamlessly switched to the second battery when the first was depleted, allowing us to finish our quarter-acre test lawn without interruption. This is a feature many users found incredibly convenient. The “Smart Cut Technology,” which adjusts power based on grass thickness, worked well to conserve battery life in thinner sections of the lawn. While the 20-inch plastic deck might not feel as robust as steel, it contributes to the mower’s light weight and is more than durable enough for typical residential use.

#6 EGO Power+ LM2135SP Self-Propelled Electric Lawn Mower – Ideal for Power and Precision

The EGO Power+ LM2135SP Self-Propelled Electric Lawn Mower is another top-tier offering from EGO, sharing many of the best qualities of our top pick. It features the same excellent Select Cut multi-blade system, which we found delivers a remarkably clean and even cut, whether mulching or bagging. The mulching performance, in particular, is superb, chopping clippings into fine bits that nourish the lawn. The high-efficiency brushless motor provides ample power, and we had no trouble tackling dense St. Augustine grass. This machine is a beast, as one user aptly put it. The Touch Drive self-propel system is just as intuitive here, making it easy to control the speed with a simple touch. The main difference from our top pick is the battery configuration; this model comes with a single, large 7.5Ah battery. We were able to mow our entire half-acre test yard with juice to spare, easily achieving the advertised 60-minute runtime. While we personally prefer the flexibility of a two-battery system, for those who want to mow and then charge a single battery, this is an excellent, powerful, and feature-rich choice that delivers a premium mowing experience.

#7 Sun Joe 24V-X2-DTS15 Scarifier and Dethatcher Kit 15-inch – Perfect for Lawn Renovation

While not a traditional lawn mower, the Sun Joe 24V-X2-DTS15 Scarifier and Dethatcher Kit is an essential tool for anyone serious about lawn health, and we felt it deserved a spot on our list. A thick layer of thatch can choke your lawn, preventing water and nutrients from reaching the soil. This Sun Joe unit tackles that problem head-on. We were incredibly impressed by how much dead grass, moss, and thatch it pulled up from our test lawn using the dethatching cylinder. The 24 spring steel tines are aggressive and effective. We then swapped to the scarifying cylinder, which uses blades to slice into the soil, improving aeration and preparing it for overseeding. The process was straightforward, and the 5-position depth control allowed us to fine-tune the aggression for different parts of the yard. As nearly every user noted, the included 10.6-gallon collection bag is far too small to be practical; it fills up in less than a minute. We found the best method was to remove the bag and follow up with a mower in bagging mode to collect the massive amount of debris. Powered by two 24V batteries, it had enough power and runtime to complete our entire front yard (about 2,000 sq ft) on a single charge. For seasonal lawn care, this tool is a must-have.

#8 Fiskars 18″ Manual Reel Mower – Suits Eco-Friendly Enthusiasts

For those who want a great workout, silent operation, and a perfectly manicured lawn, the Fiskars 18″ Manual Reel Mower is in a class of its own. This isn’t your grandfather’s flimsy reel mower. The InertiaDrive system provides significant cutting power, and we were surprised how easily it sliced through our well-maintained test lawn, including some tougher grass varieties. The “StaySharp” cutting system means the blades make no contact, which not only reduces the force needed to push but also promises to keep the blades sharp for years without manual honing. We found it significantly easier to push than older reel mowers we’ve used in the past. The cut quality is exceptional—a clean, scissor-like snip that is healthier for the grass than the tearing action of some rotary mowers. It’s fantastic for achieving that soft, carpet-like appearance. However, it’s not without the typical limitations of a reel mower. It struggles with tall weeds, sticks, and uneven terrain. This is a tool for maintenance, not reclamation. If you mow regularly (at least once a week) and have a relatively small, flat lawn, the Fiskars provides a uniquely satisfying, quiet, and eco-friendly mowing experience.

#9 Greenworks 80V 21″ Self-Propelled Lawn Mower 4.0Ah – Best for Hilly Terrain

The Greenworks 80V 21″ Self-Propelled Lawn Mower 4.0Ah is another workhorse from the Greenworks 80V Pro line that excels in challenging conditions. What stood out to us during testing was its powerful rear-wheel drive system. We took it up a steep, grassy slope in our backyard, and it climbed with impressive authority, requiring very little effort from us to guide it. This makes it an excellent choice for anyone with a hilly or uneven yard. The brushless motor, combined with the heavy-duty 21-inch steel deck, delivers a confident cut through thick grass. The SMARTCUT Technology was noticeable, as the mower audibly revved up when it hit a dense patch, ensuring a consistent cut without bogging down. The single-lever height adjustment is convenient, offering seven distinct positions. Like other Greenworks models, it folds up for easy vertical storage, a feature we can’t overstate the convenience of. A few users mentioned that the self-propel can feel a bit slow at its max setting if you walk quickly, but for a steady, powerful pace, we found it to be perfectly adequate. With its robust build and exceptional climbing ability, this mower is a reliable tool for tackling tough lawns.

#10 Greenworks 48V 21″ Self-Propelled Mower+Trimmer+Blower – Best All-in-One Starter Kit

For new homeowners or anyone looking to dive into a complete cordless lawn care system, the Greenworks 48V 21″ Self-Propelled Mower+Trimmer+Blower combo kit is an unbeatable value. The system is powered by two 24V batteries running in series to deliver 48V of power to the mower, and each tool can also run on a single 24V battery. The 21-inch self-propelled mower itself is a capable machine. We found its brushless motor had plenty of power for a typical suburban lawn, handling moderately tall grass without issue. The steel deck feels sturdy, and it offers the standard 3-in-1 options for mulching, bagging, or side discharge. While not as powerful as the 80V models, it’s more than sufficient for weekly maintenance. The real value, however, is in the included tools. The 12-inch string trimmer is lightweight and perfect for edging driveways and trimming around flower beds, and the 320 CFM blower is great for clearing off patios and sidewalks after mowing. Getting all three tools, two 5.0Ah batteries, and a dual-port charger in one package is an incredible deal. It’s the perfect way to cut the cord on all your yard work at once.

The Ultimate Buyer’s Guide: How to Choose The Right Product for You

Key Factors to Consider

• Power Source: The biggest choice is between gas, corded electric, battery-electric, and manual reel mowers. Battery technology has advanced so much that models from EGO and Greenworks now meet or exceed the power of their gas counterparts, all while being quieter, cleaner, and lower maintenance. Gas still offers raw power and infinite runtime (as long as you have fuel), while manual reel mowers are best for small, flat lawns and an eco-conscious mindset.
• Self-Propelled vs. Push: A self-propelled mower uses the engine or motor to turn the wheels, making it much easier to handle, especially on hills or large properties. Push mowers require your own effort to move them forward. If you have a flat lawn under a quarter-acre, a push mower like the EGO Power+ LM2112 can save you money and is often lighter. For any slopes or larger yards, we strongly recommend a self-propelled model.
• Deck Size and Material: The deck width (cutting swath) determines how many passes you’ll need to make. For most residential lawns, a 20- to 22-inch deck is the sweet spot. Deck material is also important; steel decks (found on many Greenworks models) are very durable but heavier, while high-quality polypropylene/plastic decks (used by EGO) are lighter and will never rust.
• Battery Ecosystem: If you choose a battery-powered mower, you’re also buying into a battery platform. Brands like EGO and Greenworks offer a huge range of other tools—trimmers, blowers, chainsaws—that all use the same batteries. This can be a huge long-term value, as you can buy future “bare tools” without the added cost of a battery and charger.

Understanding Battery Voltage (V) and Amp-Hours (Ah)

When looking at cordless mowers, you’ll see two key numbers: Volts (V) and Amp-hours (Ah). Think of them this way:

• Voltage (V) is like the power or horsepower of the motor. A higher voltage (like 80V) generally means more torque and cutting power, allowing the mower to tackle thicker, taller grass without bogging down.
• Amp-hours (Ah) is like the size of the fuel tank. A higher Ah number (like 6.0Ah or 7.5Ah) means the battery can deliver power for a longer period. A 5.0Ah battery will run longer than a 2.0Ah battery on the same tool.

The total energy in a battery is volts multiplied by amp-hours (watt-hours). This is why our top pick, the EGO Power+ LM2134SP-2, with its two 6.0Ah 56V batteries, has such an impressive total runtime.

Common Mistakes to Avoid

• Buying Too Little Power: Don’t choose a low-voltage, small-battery mower if you have a large yard with thick grass. You’ll be frustrated by constant stalling and the need to recharge mid-mow. It’s better to have more power than you need than not enough.
• Ignoring Your Terrain: A lightweight push mower might seem appealing, but if you have any significant slopes, you will regret not getting a self-propelled model. The extra cost is well worth the saved effort and strain.
• Forgetting About Storage: Mowers take up a lot of garage space. Models from EGO and Greenworks that feature quick-fold handles for compact, vertical storage are a massive space-saving advantage.

Frequently Asked Questions

What is the difference between a push mower and a self-propelled mower?

A push mower relies entirely on your physical effort to move it forward across the lawn. A self-propelled mower has a drive system that powers the wheels, so you primarily just have to guide it. Self-propelled models are ideal for lawns with hills, uneven terrain, or for anyone who wants to reduce the physical strain of mowing a large area.

Are gas or electric walk-behind mowers better?

This depends on your priorities. Gas mowers traditionally offer more power and can run indefinitely as long as you have fuel. However, they are loud, require significant maintenance (oil changes, spark plugs, fuel stabilizers), and produce emissions. Modern battery-electric mowers, like our top picks from EGO and Greenworks, now offer equivalent or superior power, are incredibly quiet, start with a button push, and require virtually no maintenance beyond blade sharpening and cleaning. For most homeowners, we believe the convenience and performance of today’s electric mowers make them the better choice.

What are the most reliable lawn mower brands?

Based on our testing and analysis of long-term user feedback, brands like EGO and Greenworks have established themselves as leaders in the electric mower space, known for their powerful performance, battery innovation, and reliability. In the manual reel mower category, Fiskars is highly regarded for its innovative designs and durable construction.

What deck size do I need for my lawn?

Deck size refers to the width of the cutting swath. For small to medium suburban lawns (up to 1/2 acre), a deck size of 20-22 inches is the most common and efficient choice. A larger deck means fewer passes to finish the lawn, but it can also make the mower heavier and less maneuverable in tight spaces.

How much should I spend on a good walk-behind lawn mower?

You can find basic push mowers for under $400. High-quality, powerful push mowers are often in the $400-$600 range. For a premium, self-propelled battery-powered model with excellent features and long runtime, expect to spend between $600 and $900. While the initial cost is higher than some gas models, the savings on fuel, oil, and maintenance add up over time.

What maintenance does a walk-behind mower require?

For battery-electric mowers, maintenance is minimal. The main tasks are cleaning grass clippings from the underside of the deck after each use and sharpening the blade once or twice a season. For gas mowers, maintenance is more involved and includes regular oil changes, spark plug replacement, air filter cleaning/replacement, and properly winterizing the fuel system.

Is a 3-in-1 mower (mulch, bag, side-discharge) worth it?

Absolutely. A 3-in-1 mower offers maximum versatility. Mulching chops clippings finely and returns them to the lawn as a natural fertilizer. Bagging provides the cleanest look and is great for collecting leaves in the fall. Side-discharge is useful for tall, overgrown grass that would overwhelm the other two systems. Having all three options allows you to adapt to any lawn condition throughout the year.

Conclusion: Our Final Recommendation

After extensive hands-on testing, we can confidently say that the age of powerful, reliable, and convenient battery-powered mowers is here. While every mower on this list has its strengths, the EGO Power+ LM2134SP-2 Self-Propelled Cordless Lawn Mower consistently outperformed the rest. Its combination of raw power, courtesy of the 56V ARC Lithium platform, and the intelligent Select Cut multi-blade system provides a cut quality that is second to none. The massive runtime from the dual 6.0Ah batteries eliminates range anxiety, while the intuitive Touch Drive self-propel system makes mowing even large, sloped yards feel effortless. It is a premium product that delivers on every promise, making it our definitive top recommendation for the best walk-behind lawn mower available today.
