How To Choose The Best Electric Walk Behind Mower
Matching a mower’s specs to your lawn’s size and how you mow is the key to a good buy. Here is what to weigh before you click.
Battery Voltage and Amp-Hours (Ah) vs. Your Lawn Size
Higher voltage (40V, 48V, 56V, 60V) generally means more torque to cut through thick or damp grass without bogging down. The amp-hour (Ah) rating tells you the energy capacity — a 5.0Ah battery will run longer than a 4.0Ah battery from the same voltage family. Look at the manufacturer’s average battery life in minutes and compare it to how long it takes you to mow.
Corded vs. Cordless — The Trade-Off
A corded mower gives you unlimited runtime with no battery anxiety, perfect for large or oddly shaped yards. The trade-off is managing an extension cord, which can be a tripping hazard and limits your range. Cordless models offer freedom of movement, but you are locked into a maximum runtime before a recharge break is needed.
Cutting Width and Height Adjustments
A wider cutting deck (20 to 21 inches) means fewer passes to finish the lawn. A mower with a wider range of height settings, typically from 1 to 4 inches, lets you cut different grass types and seasons without scalping the lawn. More positions (6, 7, or 8) give you finer control over the final look.
Self-Propelled vs. Push Mowers
Self-propelled mowers use a drive system to move the mower forward, reducing the effort required on slopes or large lawns. Push mowers are lighter, simpler, and often more affordable, but require you to provide all the pushing force. Consider the slope of your yard and the total square footage.

In‑Depth Reviews
1. WORX Nitro Cordless Lawn Mower, 20″ Electric Mower for 1/2 Acre, Brushless Push Lawn Mower with 7-Position Height Adjustment, 2 × 5.0 Ah Batteries & Charger Included, WG752
The half-acre champ with a runtime that outlasts most of the competition.
You get a generous 50 minutes of average battery life from the WORX Nitro, compared to the SnapFresh 40V mower’s 42 minutes. That means you spend more time cutting and less time waiting for a recharge. The 20-inch cutting width covers ground quickly.
The AeroDeck technology uses a vented design that boosts air volume in the cutting deck to prevent clogs and clumping, which owners mention makes bag collection more efficient. IntelliCut technology uses patented sensors to automatically dial up the cutting speed when the grass gets thick and dial it back in lighter areas to extend runtime. The 7-position height adjustment lever lets you move from 1.5 to 4 inches with a single hand. The included two 20V 5.0Ah PowerShare Pro batteries work with over 140 other WORX tools, so you are building a battery ecosystem, not buying a one-off mower.
One reviewer who has used WORX for 14 years noted that the 40V system provided ample runtime, finishing a half-acre with 60% charge remaining. The 20-inch cut reduces the number of passes compared to smaller 17-inch models. The mower weighs 55.6 pounds, which owners say is light enough to handle without self-propulsion.
What Makes It a Top Pick
- 50-minute battery average life is generous for a full yard
- 21-inch cutting width covers ground quickly
- Works with the WORX PowerShare tool system
- 7-position height adjustment gives fine control
Limitations to Note
- Batteries can be a bit hard to remove from the mower
- Fixed front wheels slightly reduce maneuverability compared to swiveling ones
- Some customers note a 1-2 second lag when the motor shuts off
Best for the big yard owner: If you are cutting close to half an acre and want a single-charge finish plus a whole tool ecosystem, this is the strongest mid-range option.
The trade-off to know: The plastic-heavy design is lighter, but some owners question its long-term durability compared to steel-deck models.
2. EGO POWER+ Cordless Electric Lawn Mower, Self-Propelled, Includes 56V 7.5Ah Battery and Rapid Charger (LM2135SP) Plus Extra 5.0Ah Battery (BA2800T)
The self-propelled powerhouse with interchangeable blades to match the season.
The EGO LM2135SP gives you gas-level cutting torque without the maintenance. The bundle also includes an extra 5.0Ah battery for even more runtime.
The Touch Drive self-propelled system engages with a touch of your palm, and you adjust speed with a scroll dial. The Select Cut multi-blade system lets you swap between mulching, high-lift bagging, and extended runtime lower blades, all underneath one upper blade. The cutting width is 21 inches, and the 8-position height adjustment lets you choose a setting from 1 inch to 4 inches — that is more height options than the Greenworks 48V mower’s 4 positions. Reviewers point out that the self-propel feature makes mowing a sloped 1/3-acre yard easy, but note that battery life does drop when using the self-propel in wet or tall grass.
Reviewers consistently mention how quiet and easy to start it is compared to a gas mower. One owner noted that the mulching blade stays sharp for about a season before needing attention. The mower is compatible with all EGO 56V ARC Lithium batteries, which is helpful if you already own EGO trimmers or blowers.
Why It Stands Out
- 60-minute battery life is the highest in this lineup
- Select Cut system lets you swap blades for different tasks
- Self-propelled drive with variable speed
- 8 cutting height positions give you very granular control
What Holds It Back
- Self-propel performance slows as the battery drains
- May leave stragglers on the lawn compared to a high-end gas mower
- Battery weight and price are higher than mid-range options
Ideal for the hills and big yards: If your lawn has slopes or covers a significant area and you want self-propulsion with lots of runtime, this is the premium choice.
One real-world issue: Owners say the self-propel does not always engage on the first try, so be prepared for a brief learning curve.
3. Honda HRX-BE 21-Inch Walk Behind 12 AH Battery Powered Lawn Mower with 2 Battery Bays, Variable Speed Self Propelled Lawn Mower with 2.2 Bushel Capacity, Easy-Off Grass Bag (HRX217YXBEXA6)
The legendary Honda build quality, now in a battery-powered version that cuts as clean as its gas cousins.
If a pristine cut is your top priority, the Honda HRX-BE delivers it. The 4-in-1 Versamow system with a Clip Director lets you mulch, bag, discharge, and shred leaves without needing to swap any attachments. The twin blade MicroCut System uses four cutting surfaces to produce very fine clippings.
The battery life is up to 45 minutes on the included 12 Ah battery, with a second battery bay ready for an extra 12 Ah battery (sold separately) to double the run time. The dual-lever height adjustment offers 7 cutting heights between 0.75 and 4 inches — the lowest minimum height in this guide, which matters if you maintain a tight Bermuda grass lawn. The e-Select Drive electric transmission gives you adjustable speed from 0 to 4 mph using a button. Owners who switched from a 12-year-old Honda gas mower report that the battery model meets their expectations for power and reliability, with one owner consistently mowing a full acre on a single battery. The 5-year residential warranty is the longest coverage in this comparison.
A few buyers reported receiving units with defects, such as the self-propel not working on arrival or a front wheel tilted inward. However, the nationwide service network and parts availability are a key advantage over smaller brands.
What Makes It Exceptional
- Versamow system needs no tool changes for 4 cutting modes
- MicroCut twin blades produce ultra-fine clippings
- Lowest minimum cut height (0.75 inches) for tight lawns
- 5-year warranty and nationwide service support
Where It Falls Short
- Recharge time is up to 6 hours for the included battery
- A spare 12 Ah battery costs around
- Heavier than most other electric mowers in this guide
Match for the cut perfectionist: If you are willing to invest in a premium machine with an class-leading deck design and service network, the HRX-BE is a long-term buy.
The honest drawback: The 6-hour recharge time means you will want that second battery if your lawn is large, and that adds significant cost.
4. SKIL PWR CORE 40 Brushless 40V 20-Inch Self-Propelled Mower Kit, Includes 6.0Ah Battery and Auto PWR JUMP Charger – SM4910C-11
The self-propelled electric mower that brings premium features at a mid-range cost.
The SKIL PWR CORE 40 splits the difference between the budget cordless options and the high-end EGO or Honda models. It offers self-propelled drive with variable speed, a feature rarely found at this price point. The digital brushless motor runs on a 40V 6.0Ah battery that delivers up to 55 minutes of runtime, which beats the Greenworks 48V mower’s 45 minutes. The cutting width is 20 inches.
The 7-position single-lever height adjustment lets you go from 1.5 to 4 inches. The folding handle telescopes for compact vertical storage. The battery and charger use the PWR JUMP technology, which shoppers say charges quickly. One reviewer noted that the battery held a good charge, cutting an entire yard with a short break to rest and charge. The mower is quiet, which makes early-morning mowing possible without disturbing neighbors.
Some owners say the self-propel motor is louder than the blade motor itself. A few also report that the mower struggles at the lowest cutting height setting on a mossy lawn, so it may not be ideal for the most delicate turf. The weather-resistant construction adds durability for storage in a shed or garage.
The Value Highlights
- Self-propelled drive at a mid-range price point
- 55-minute battery life is competitive with higher-priced models
- 7-position height adjustment for fine control
- Folding handle for space-saving storage
Trade-Offs to Consider
- Self-propel can be louder than the blade motor
- Not ideal for very low cuts on mossy or uneven turf
- Some owners experienced a battery recall (since resolved)
The right pick for the self-propel seeker: If you want a self-propelled mower without paying flagship pricing, this SKIL gives you the drive system and a solid 55 minutes of runtime.
Know before you buy: The self-propel noise may be a nuisance if you prefer a very quiet mowing experience.
5. Cat DG670 60V 21″ Cordless 3-In-1 Cutting Modes, Brushless Push Lawn Mower with TorqLogic – Battery & Charger Included
The 60-volt brute that automatically adjusts power as the grass gets thicker.
The Cat DG670 runs on a 60V system, which is higher voltage than the 40V WORX and SKIL models, giving it more torque for dense grass. The TorqLogic technology automatically adjusts power to fit lawn conditions — it boosts power when the grass is thick and drops it when conditions are light to extend runtime. The cutting width is 21 inches, the same as the EGO and Honda flagships. The brushless motor 2.0 is claimed to produce 40% more power than standard brushless motors, according to the brand.
A unique feature is the dual battery port, which lets you keep two batteries on board. When one runs out, the other is ready to go. This reduces downtime on larger lawns. The 3-in-1 cutting modes switch between bagging, mulching, and side discharge with a simple lever flip — no tools required. The foldable handle and LED lights for visibility in darker conditions add convenience. Buyers report that the mower handles a 1/3 acre lot on a single 5.0Ah battery and that the fine mulching design leaves no clippings lying on the grass.
However, some owners experienced reliability issues: one mower’s power drive failed within the first 10 minutes, and another would not start the blade on the second use. The mower weighs 68.3 pounds, making it one of the heavier push mowers in this guide, which may be tiring on a sloped lawn.
what separates it
- 60V system provides higher torque for thick grass
- Dual battery port for hot-swapping without leaving the yard
- TorqLogic auto-adjusts power to conditions
- Includes LED lights for low-light mowing
Areas of Concern
- Some owners reported defective units on first or second use
- Relatively heavy at 68.3 pounds for a push mower
- Only 3 height positions, which is less control than most
Best for the thick lawn owner: If you consistently deal with dense, wet grass and need the extra torque of a 60V system, the Cat has the power.
The catch: Quality control seems inconsistent based on owner reports, so buy from a retailer with a good return policy.
6. SnapFresh 40V 17” Brushless Lawn Mower – 2 x 5.0Ah Batteries Electric Cordless Push Mower with Fast Charger, 6-Level Height Adjustment, 45L Grass Bag
The entry-level cordless mower that saves you money without leaving you stranded mid-lawn.
The SnapFresh 40V is the most affordable battery-powered model in this guide, but it does not skip on essentials. It delivers up to 42 minutes of runtime from two 5.0Ah batteries, enough for a 1/3 acre lawn. “The dual charger fully recharges both batteries in about 120 minutes for less downtime,” owners mention. The brushless motor keeps noise under 96 dB, which is quieter than most gas mowers.
The 6-level height adjustment ranges from 1 inch to 3 inches, which is a narrower range than the BLACK+DECKER corded mower’s maximum of 4 inches. The 2-in-1 function supports mulching and rear bagging, and the 45L grass collection bag is generous for the size. Owners love the lightweight feel and the fact that it is much quieter than gas. One older female reviewer noted it was “a great fit for me” because of the easy assembly and light weight. Some users mention the plastic components feel a bit cheap, but for a small yard that needs a simple, low-cost solution, it is tough to top.
The maximum adjustable cutting height is 7.62 centimeters compared to the BLACK+DECKER’s 10.16 centimeters, so it is less suited for lawns where you prefer a tall cut.
Why It Is a Budget Star
- Two 5.0Ah batteries included for extended runtime
- Low-noise brushless motor
- Very easy to assemble and operate
- 45L grass bag reduces emptying frequency
Where You Compromise
- Narrow 17-inch cut means more passes
- Plastic components feel less durable than metal-deck models
- Maximum cutting height is lower than other options
Ideal for the small-yard owner on a budget: If your lawn is under 5,000 square feet and you want a quiet, cordless mower without spending much, this is the pick.
The honest limit: The plastic build may not survive years of heavy use, and the height range is limited for taller grass.
7. BLACK+DECKER Electric Push Lawn Mower, Corded, 13 Amp, 20-Inch Cutting Deck, 6 Setting Height Adjustment, Compact Storage, Collection Bag (BEMW213)
The corded workhorse with unlimited runtime for those who cannot afford a dead battery mid-lawn.
If you have a large yard or simply hate the thought of running out of power before finishing, the BLACK+DECKER BEMW213 solves that with a corded design. The 13 amp motor provides consistent power without the voltage sag that battery mowers experience as they drain.
The winged blade design is tune for cutting and collecting grass, and the push-button start means no pulling a cord. The folding handle lets the mower fit into small storage spaces. Owners praise the easy 5-minute assembly and the powerful motor that handles tall grass. “Deflector door cracked first year; motor smoked under 100 hours due to shaft misalignment,” one buyer mentioned, highlighting the quality control issues that can appear. Another reviewer noted that the handle knobs break easily and the blade engage bar has high spring tension that causes hand fatigue during long mows.
The corded limitation means you are always tethered to an outlet, and you will need a heavy-duty extension cord. On settings 1-3, the mower can bog in thick or wet grass, so owners recommend using a higher setting for challenging conditions. The bag mode is reportedly a bit of a hassle to operate.
Strengths to Consider
- Unlimited runtime — no battery anxiety
- 13 amp motor provides consistent power
- 20-inch cut is competitive with battery models
- Easy push-button start and tool-free height adjustment
Weaknesses to Weigh
- Corded — limited by extension cord range and safety
- Some customers note failures under 100 hours of use
- Engine handles and spring tension cause fatigue
Best for the no-constant-recharge owner: If your lawn is large and you do not want to manage battery levels, this corded mower keeps going as long as you do.
The honest trade-off: Quality control is a gamble based on reviews, and managing a long extension cord is a daily reality you must accept.
8. Greenworks 48V (24V x 2) 20″ Brushless Cordless (Push) Lawn Mower (LED Headlight), (2) 4.0Ah Batteries and Dual Port Rapid Charger Included (200+ Compatible Tools)
The 48V mower that doubles as the gateway to a 200-plus tool battery system.
The Greenworks 48V mower uses two 24V batteries that combine for 48V of power, which is a step up from the 40V SnapFresh. The cutting width is 20 inches, the same as the BLACK+DECKER. The steel deck is more durable than the plastic decks on lower-priced models.
The 4-in-1 system offers mulching, rear bagging, side discharge, and a Turbo button for maximum power during leaf pickup or thick grass. The dual port rapid charger brings both batteries back up quickly. The minimum adjustable cutting height is 1.38 inches compared to the BLACK+DECKER’s 1.5 inches, so you can get a tighter cut. The mower is part of the Greenworks 48V platform, which includes over 200 compatible tools, but “Battery life insufficient for 1/3 acre (died halfway),” one owner reported, so it is best for smaller lawns or if you already own more batteries from the range.
Owners who switched from gas mowers love the quiet operation and the push-button start. One long-term owner noted it works reliably after 2+ years and handles thick, tall grass without clogging. The mower does not have a self-propelled mode, so you are providing all the push effort on a 67.2-pound machine.
Why It Makes Sense
- Steel deck is more durable than plastic alternatives
- Turbo button for extra power when needed
- Part of a 200+ tool battery platform
- Reliable long-term performance reported by owners
Where It Gives Ground
- Battery life may fall short for a full 1/3 acre on a single charge
- No self-propelled drive; requires all manual pushing
- Only 4 height positions, which is less than the 7 on the WORX
A solid pick for the Greenworks ecosystem user: If you already own Greenworks 24V batteries or plan to buy multiple tools from their lineup, this mower makes financial sense.
The one caveat: For a lawn larger than 1/4 acre, you will likely need a spare battery to avoid stopping halfway.
Understanding the Specs
Battery Voltage & Amp-Hours
Voltage (V) determines how much torque the motor can produce — think of it as the “push” behind the blade. A 60V mower will generally power through thick, wet grass better than a 40V model. Amp-hours (Ah) indicate the total energy capacity — how long the mower can run before needing a charge. A 5.0Ah battery typically lasts longer than a 4.0Ah battery at the same voltage. Runtime also depends on grass thickness, operator technique, and whether the mower is self-propelled (which drains the battery faster).
Cutting Width & Height Adjustment
Cutting width is the width of the mower deck — wider decks cover more ground per pass, reducing mowing time. A 21-inch deck is faster than a 17-inch one. Height adjustment lets you set how short or long the grass is cut. More positions (6, 7, or 8) give you finer control to match the season or grass type. The minimum and maximum heights are measured in inches — a lower minimum (like 0.75 inches) is ideal for tight Bermuda lawns, while a higher maximum (4 inches) keeps grass healthy in hot weather.
Brushless vs. Brushed Motors
A brushless motor uses electronic controls instead of physical brushes to transfer power. This makes the motor more efficient, quieter, and longer-lasting than a brushed motor. Most modern electric mowers use brushless motors because they provide more torque per watt of power and do not require the maintenance that brushed motors do (replacing worn brushes). The trade-off is a slightly higher upfront cost, but the thermal efficiency and lifespan gains typically offset it over a few seasons.
Self-Propelled vs. Push Mowers
A self-propelled mower has a drive system that moves the wheels forward, so you only need to guide the mower. The speed is usually adjustable, which is helpful on slopes or for longer mowing sessions. A push mower requires you to provide all the forward motion. Push mowers are lighter, simpler, and more affordable, but they can be tiring on large or hilly lawns. If your yard is over a quarter acre or has any slope, self-propulsion is a significant comfort upgrade.
