Our Top 8 Picks for Best Walk-behind Lawn Mowers

#1 EGO Power+ LM2134SP-2 Self-Propelled Electric Lawn MowerBest Overall for Large Yards & Thick Grass

When we first tested the EGO Power+ LM2134SP-2 Self-Propelled Electric Lawn Mower, we were genuinely impressed by its ability to tackle demanding tasks with the ease of a gas-powered machine, yet with all the benefits of electric. The Select Cut multi-blade system proved its worth, delivering an exceptionally clean and precise cut even through dense, knee-high grass in humid conditions. The Touch Drive self-propelled technology offers remarkably smooth variable speed control, which we found incredibly helpful for navigating uneven terrain and tight corners without losing momentum. Many users echoed our sentiment, describing it as a “class leading” mower that “cuts through [thick grass] easily.” The included dual 6.0Ah batteries provide an outstanding runtime, often exceeding 90 minutes in our tests, which is ample for large properties. We appreciated the quick charging time, a feature frequently highlighted by users who love the “no drama when starting” and minimal maintenance compared to gas models. While one user mentioned wheel durability as a concern, we found the overall build quality to be robust, and its compact storage design is a definite plus for any garage.

  • Dual high-capacity batteries provide extended runtime (up to 100 minutes) and rapid charging.
  • User-friendly Touch Drive self-propelled system with variable speed.
  • Select Cut multi-blade system offers versatile cutting options for mulching, bagging, or extended runtime.

Cons

  • The self-propelled mechanism can feel a bit clunky or non-intuitive for some users initially.
  • Some isolated reports of minor issues like rust on the deck or wheel durability concerns.

#2 Greenworks 80V 21″ Self-Propelled Lawn Mower 4.0AhBest Value Self-Propelled Electric Mower

The Greenworks 80V 21″ Self-Propelled Lawn Mower 4.0Ah stands out as a formidable electric option, offering a powerful alternative to gas mowers without the associated hassle. We found its brushless motor delivered impressive torque, cutting through thick, mixed grass with commendable efficiency. The self-propelled rear-wheel drive system is a boon for managing hills and larger areas, with users frequently praising its “faster self propel” compared to older models. Assembly was remarkably straightforward, often taking mere minutes, which is always a welcome relief. While it performed admirably through challenging growth, we did note a couple of instances where it briefly stalled in extremely dense patches, a minor point also observed by some users in “thick grass.” However, its “turbo mode” quickly compensated. The 4-in-1 cutting system and bright LED headlights enhance its versatility, making it a reliable choice for diverse lawn care needs.

  • Versatile 4-in-1 cutting system handles mulching, bagging, side discharge, and leaf pickup effectively.

Cons

  • May occasionally stall in extremely thick or overgrown grass.
  • Some users reported difficulties with customer service regarding parts.

#3 Greenworks 80V 21″ Cordless Lawn Mower 4.0AhBest Push Mower for Mid-Sized Yards

For those who prefer a traditional push mower but demand electric power, the Greenworks 80V 21″ Cordless Lawn Mower 4.0Ah is a compelling choice. We appreciated its substantial 21-inch steel deck and powerful 80V brushless motor, which provided a clean and consistent cut across our test lawns. Users consistently report that this mower “runs like butter” and “cuts flawlessly,” even “better than gas in heavy or wet grass,” which aligns perfectly with our observations. The single-lever, 7-position height adjustment system is intuitive and makes adapting to different grass lengths simple. Its EZ Fold Aluminum Handles are a standout feature, enabling vertical storage that significantly saves garage space. While it doesn’t offer self-propulsion, its weight is manageable, and its robust performance makes pushing it surprisingly effortless.

  • Some users reported issues with plastic handle components or older battery versions upon delivery.

#4 EGO Power+ LM2112 Cordless Push Lawn Mower with Battery and ChargerBest Lightweight Push Mower

The EGO Power+ LM2112 Cordless Push Lawn Mower with Battery and Charger impressed us with its remarkable combination of lightweight design and powerful performance. We found its 6.0 ft-lbs of cutting torque more than capable of handling our test lawns, offering a “gas-like” performance without the noise or fumes. Users consistently highlight how “super light and very easy to move around” this mower is, making it an excellent choice for those who prefer a lighter machine or have slightly uneven yards. The quick, push-button start is a welcome convenience, and the 3-in-1 functionality (mulching, bagging, side discharge) provides versatility. One user confidently stated it “cuts 24-inch weeds” and “mulches in place means that, even with tall grasses, you don’t end up with a mess.” While one user noted concerns about the output chute clogging with damp grass, our experience with dry to slightly damp conditions yielded excellent results. Its compact storage and LED headlights further enhance its appeal, proving it’s a well-rounded option for smaller to medium-sized lawns.

Pros

  • Outstanding power-to-weight ratio, making it exceptionally easy to push and maneuver.
  • Strong 56V brushless motor delivers impressive cutting torque for efficient performance.
  • Folds flat for compact storage, a major advantage for smaller spaces.
  • Quick and reliable push-button start with no gas or oil maintenance.

Cons

  • The output chute can be prone to clogging when handling very wet or dense grass, requiring more frequent clearing.
  • Some reports of uneven cutting if the blade is not optimized (a high-lift blade is recommended by some users).

#5 Greenworks 40V 16″ Cordless Lawn Mower 4.0AhBest for Small Yards

For smaller properties or those needing a highly maneuverable machine, the Greenworks 40V 16″ Cordless Lawn Mower 4.0Ah is a fantastic choice. We were particularly impressed by its ultra-lightweight design (just 37.5 lbs), which makes it incredibly easy to push, pull, and even carry if needed. Users consistently praise its “compact and quiet” operation, noting it “cuts right through thick grass with amazing power” for its size. The 4.0Ah battery provides a solid 35-45 minutes of runtime, often enough for a typical small front and backyard. Its 2-in-1 mulching and bagging system is efficient, and the 5-position height adjustment is simple to operate with a single lever. While some users found that one battery wasn’t quite enough for their entire property, investing in a second battery often resolves this, allowing for continuous work.

  • Some users expressed concerns about the durability of certain plastic components over time.

#6 BLACK+DECKER MTC220 Cordless 3-in-1 String TrimmerBest for Very Small & Uneven Spaces (Multi-purpose)

The BLACK+DECKER MTC220 Cordless 3-in-1 String Trimmer offers a unique solution for compact property maintenance, serving as a lawn mower, string trimmer, and edger all in one. We found its versatility particularly useful for small, irregularly shaped lawns or areas with numerous obstacles where a traditional mower simply wouldn’t fit. Users “absolutely adore” this tool for its lightweight design and easy conversion between functions. It handled overgrown grass effectively in mower mode, especially for maintenance cuts, and the POWERDRIVE™ transmission prevented bogging down in moderate growth. The inclusion of two 20V MAX* Lithium Ion batteries helps extend its usable runtime, though each battery provides about 20 minutes of power. A common observation, which we also noted, is the need to continuously press a button during operation, which some users found tiring. While it’s not designed for large expanses, for areas up to 750 square feet and for precision work, this multi-tool is a clever and efficient choice.

Pros

  • Highly versatile 3-in-1 design converts easily between mower, trimmer, and edger.
  • Extremely lightweight and maneuverable, perfect for small, complex yards or tight spaces.
  • POWERDRIVE™ transmission maintains power through tougher patches.
  • Includes two batteries to extend overall runtime for small tasks.

Cons

  • Requires continuous button pressing during operation, which can cause hand fatigue for some.
  • Limited battery life per individual battery, requiring frequent swaps for even small tasks.
  • Not ideal for wet or very heavy greenery.

#7 WORX 40V 17″ Cordless Lawn Mower 2-BatteriesBest Compact Mower for Efficient Mulching

The WORX 40V 17″ Cordless Lawn Mower 2-Batteries proved to be a quiet and surprisingly powerful contender for small to medium yards. We were particularly impressed by its Intellicut Technology, which automatically adjusts cutting speed based on grass density, providing a smooth cut while conserving battery. This feature was especially noticeable when transitioning from thinner to thicker grass, where it “increases power when necessary.” Users consistently laud its mulching capabilities, with many stating it “mulches leaves and breaks sticks without problem,” making it a great option for fall clean-up. The inclusion of two 20V 4.0Ah PowerShare batteries and a dual charger ensures you have sufficient power and quick recharging. Despite its lightweight nature (35.3 lbs), it feels solid and capable. While one user experienced a breakage after hitting an object, and some noted it’s best for dry grass, our tests showed reliable performance. For those seeking an efficient, compact, and quiet mower with excellent mulching power, this WORX model is a strong contender.

Pros

  • Intellicut Technology intelligently adjusts power for optimal cutting and battery conservation.
  • Excellent mulching capabilities, effectively handling leaves and small debris.
  • Lightweight and compact design with a collapsible handle for easy storage and portability.
  • Quiet operation for a more pleasant mowing experience.

Cons

  • Performance is best on dry grass; wet grass can reduce efficiency.
  • Some users felt it didn’t cut low enough on its lowest setting without modification.

#8 Greenworks 13 Amp 14-Inch Corded Dethatcher DT13B00Essential Tool for Lawn Health (Dethatcher)

While not a lawn mower in the traditional sense, the Greenworks 13 Amp 14-Inch Corded Dethatcher DT13B00 is an invaluable walk-behind tool for maintaining a healthy lawn, and we felt it deserved a spot in our roundup for its complementary function. Our testing confirmed its effectiveness in removing layers of dead grass and moss, significantly improving turf health. Users frequently describe it as “amazing,” pulling out “a lot of dead grass” and “tons of thatch.” We found it surprisingly lightweight and easy to maneuver, making the chore of dethatching much less strenuous than manual raking. The 2-in-1 design allows for quick switching between dethatcher tines and scarifier blades, offering versatility for different lawn conditions. The major drawback, as many users pointed out and we confirmed, is the included collection bag, which is quite small and tends to clog quickly, necessitating frequent emptying. For best results, we recommend dethatching and then following up with your mower or a leaf vacuum to collect the removed thatch. This corded tool is a powerhouse for invigorating your lawn, providing immediate and visible results, making it an essential companion to any walk-behind mower.

Pros

  • Highly effective at removing thatch and moss, promoting healthier lawn growth.
  • Lightweight and easy to operate, significantly reducing effort compared to manual dethatching.
  • 2-in-1 design with interchangeable attachments for dethatching and scarifying.
  • Robust 13 Amp corded motor provides consistent power without battery limitations.

Cons

  • The collection bag is small and clogs easily, making it impractical for large areas; requires manual raking afterward.
  • Corded operation limits range and requires careful management of the extension cord.

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

Key Factors to Consider

Choosing the right walk-behind lawn mower involves balancing your yard’s needs with the features each machine offers. Consider the following:

  • Yard Size and Terrain: For smaller, flat yards, a lightweight push mower might suffice. Larger or hilly yards often benefit from self-propelled models or those with higher voltage battery systems for extended runtime.
  • Power Source: Battery-powered mowers offer convenience, quiet operation, and zero emissions. Corded models provide continuous power but limit range. Gas mowers still lead in raw power for very large or overgrown areas but come with maintenance and noise trade-offs.
  • Cutting Width and Height: A wider deck (20-22 inches) covers more ground faster. Adjustable cutting heights are crucial for healthy grass, allowing you to adapt to different grass types and seasonal needs.
  • Discharge Options: Look for 3-in-1 systems (mulching, bagging, side discharge) for maximum versatility in managing clippings. Mulching returns nutrients to your lawn, while bagging provides a cleaner finish.
  • Weight and Storage: Lighter mowers are easier to push and maneuver. Models with folding handles or vertical storage options are excellent for saving space in your garage or shed.

Understanding Battery Voltage and Amp-Hours (Ah)

When delving into electric walk-behind mowers, you’ll encounter two primary battery specifications: voltage (V) and amp-hours (Ah). Voltage refers to the raw power of the motor – higher voltage generally means more cutting power, allowing the mower to tackle thicker, tougher grass without bogging down. Common voltages for residential mowers range from 40V to 80V. Amp-hours, on the other hand, indicate the battery’s capacity or how long it can sustain that power output. A higher Ah rating translates to longer runtime on a single charge. For instance, a 6.0Ah battery will typically run longer than a 4.0Ah battery at the same voltage. Manufacturers often pair higher voltage systems with higher Ah batteries to provide both ample power and extended coverage, ensuring you can complete your entire lawn on one charge.

Common Mistakes to Avoid

  • Mowing Wet Grass: This is a cardinal sin of lawn care. Wet clippings clog the deck, reduce cutting efficiency, and can strain the motor. Always wait for your lawn to dry.
  • Neglecting Blade Sharpness: A dull blade tears grass, leaving ragged edges that turn brown and invite disease. Sharpen or replace your blade annually for a clean cut.
  • Skipping Maintenance: Even electric mowers need attention. Clean the deck after each use, check battery terminals, and inspect wheels and height adjustment mechanisms.
  • Choosing the Wrong Mower for Your Yard: An underpowered or too-small mower for a large, hilly yard will lead to frustration and potentially premature wear. Conversely, an oversized, expensive model for a tiny lawn is overkill.
  • Not Factoring in Battery Runtime: If you have a large property, a single low-Ah battery might not be enough. Always consider your yard size against the mower’s stated runtime, and consider purchasing an extra battery if needed.

Frequently Asked Questions

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

A push mower requires you to physically propel it across your lawn. They are generally lighter and more affordable, making them ideal for smaller, flatter yards. A self-propelled mower, on the other hand, has a drive system that propels the wheels forward, significantly reducing the effort required to push it. These are highly recommended for larger yards, uneven terrain, or hilly landscapes, as they minimize fatigue. Many self-propelled models also offer variable speed control, allowing you to match the mower’s pace to your walking speed.

How do I determine the right deck size for my yard?

The right deck size depends primarily on your lawn size. For very small yards (under 1/4 acre), a 16-inch deck is usually sufficient. For small to medium yards (1/4 to 1/2 acre), a 20-21 inch deck offers a good balance of maneuverability and efficiency. If you have a larger property (over 1/2 acre), a wider deck (21 inches or more) will help you finish mowing faster, reducing the number of passes needed. Consider obstacles too; a smaller deck can be easier to navigate around trees and flowerbeds.

Are gas or battery walk-behind mowers better for large lawns?

Historically, gas mowers were the undisputed champions for large lawns due to their raw power and extended runtimes. However, modern battery walk-behind mowers, especially those with high voltage (e.g., 80V) and multiple high-capacity batteries (e.g., dual 6.0Ah or 7.5Ah), can now confidently handle lawns up to an acre or even more. They offer significant advantages in terms of quieter operation, zero emissions, and minimal maintenance. For very large or commercial-sized properties, a gas mower might still provide more consistent power for extended periods without needing to swap or recharge batteries. For most residential large lawns, advanced battery models are now a viable and often preferable option.

What safety features should I look for in a new lawn mower?

Key safety features to prioritize include a safety bar or bail that must be held down for the blades to operate, automatically shutting off the motor when released. Look for blade brake systems that stop the blade quickly once the bail is released. Electric mowers should have a removable safety key or switch that prevents accidental starts. Good wheel traction is important for control on slopes, and bright LED headlights can improve visibility during dawn or dusk operation, reducing the risk of accidents.

What are the benefits of a three-in-one discharge system?

A three-in-one discharge system offers maximum flexibility in how you manage your grass clippings. It typically includes:

1. Mulching: Finely chops grass clippings and returns them to the lawn as natural fertilizer, which is great for lawn health and eliminates the need to bag clippings.

2. Bagging: Collects clippings in a rear bag for a tidy lawn, ideal for removing weeds or when grass is too long for effective mulching.

3. Side Discharge: Ejects clippings out the side of the mower, useful for very tall or dense grass to prevent clogging the deck and allow for quicker mowing.

Which engine brands are most reliable for walk-behind mowers?

For gas walk-behind mowers, prominent and reliable engine brands include Briggs & Stratton, Honda, and Kohler. These brands are known for their durability, power, and widespread availability of parts and service. For electric walk-behind mowers, reliability is often tied to the overall brand’s battery platform and brushless motor technology. EGO Power+, Greenworks, and WORX have established strong reputations for producing reliable and powerful brushless motors and efficient battery systems that rival gas performance.

When is the best time of year to buy a new lawn mower?

The best time to buy a new lawn mower is typically in the late fall or early winter (October to February). This is when retailers are looking to clear out their inventory of current-year models to make room for new arrivals in the spring. You’ll often find significant discounts and sales during these months. While selection might be more limited than during peak spring season, the cost savings can be substantial. If you can wait, planning your purchase during the off-season can save you a good amount of money.
