How To Choose The Best Brushless Motor Lawn Mower
The move from gas to a brushless motor mower is a real upgrade in ease and quiet, but the biggest mistake first-time buyers make is matching the battery size to the yard. A small battery on a large lawn means you are waiting for a recharge halfway through. Think about your yard’s square footage and the mower’s runtime in minutes to avoid that frustration.
Deck Size and Your Yard
A 14-inch deck will feel nimble for tight flower beds but will take many passes on a quarter-acre lot. A 20 or 21-inch deck covers more ground each pass, so you finish faster. The trade-off is weight — the smaller decks are much lighter and easier to maneuver around obstacles.
Battery Voltage and Amp-Hours (Ah)
Voltage (V) dictates the motor’s torque capability; higher voltage usually means more cutting power through thick grass. Amp-hours (Ah) tells you the total energy storage. A 40V system with two 5.0Ah batteries has more total runtime than a single 40V 2.5Ah battery. Look for at least a 5.0Ah battery if your lawn is around a third of an acre.
Self-Propelled vs Push Mower
If your yard has a slope or you have a larger lawn (over a quarter acre), a self-propelled mower with a variable speed control keeps you from getting tired out halfway through. A push mower is lighter and simpler, making it a great choice for flat, small yards where you want to keep the weight down.

In‑Depth Reviews
1. SKIL PWR CORE 40 Brushless 40V 20-Inch Self-Propelled Mower Kit, SM4910C-11
Self-propelled muscle that glides through a full yard without breaking a sweat.
This SKIL mower brings a self-propelled drive system with variable speed control, so you can match the pace to the thickness of the grass without pushing hard. It runs on a 40V 6.0Ah battery that delivers up to 55 minutes of runtime — 55 minutes (KraftSense offers 45 minutes) for covering a bigger lawn in one go.
Buyers report the “Battery lasts ~1 hour for both yards,” which backs up the official spec. The push-button start and foldable handle make starting and storing it simple.
It also offers 3-in-1 functionality (bagging, mulching, rear-discharging), so you can switch based on your yard’s needs. The catch is the weather-resistant construction is durable but not indestructible, and some early units had a battery recall that you may want to check for your unit.
Why it earns the top spot
- Self-propelled with variable speed reduces effort on slopes
- 55-minute runtime edges out most rivals by a meaningful margin
- 7 height settings give precise control for different grass types
What to check
- Some early units had a battery safety recall
- Not the lightest option at over 50 pounds
Ideal for: Anyone with a medium to large yard who wants self-propelled ease and the longest single-charge runtime here.
Caveat: If you have a steep, wet lawn you may need a higher height setting to avoid clogging with moss.
2. EGO POWER+ Electric Lawn Mower, 56V 6.0Ah Battery, LM2114SP
Heavy-duty torque in a 56V package that outmuscles many gas mowers.
EGO’s LM2114SP runs on a 56V ARC Lithium battery that delivers up to 6.0 ft-lbs of cutting torque, which the maker says exceeds gas-powered performance. It gives you a 21-inch deck, 7 positions from 1.25 to 4 inches, and a claimed 50-minute runtime. The dual-toggle handleset lets you engage the self-propel system with either hand, which is a nice touch when you are turning around obstacles.
Bright LED headlights let you mow in the evening, and the 3-in-1 function handles mulching, bagging, and side discharge. Owners mention it cuts cleanly and powers through thick grass — one owner reports it “cuts better than several gas models.” At 84 pounds it is the heaviest mower here, but the self-propel system makes it feel lighter to push.
Compared to the Greenworks MO48L520, the EGO offers more available runtime and a higher voltage for tougher cutting conditions. Buyers with a professional use case and a steep hill say it “battery lasts full yard” and is a “great upgrade from gas.”
Why it stands out
- Strong cutting torque that matches or beats gas mowers
- LED headlights extend usable mowing time into dusk
- Dual-handle self-propel trigger is convenient
What to consider
- Heaviest option at 84 pounds, even with self-propel
- May need an extra battery for larger yards
Best for: Anyone who wants the raw power to rival a gas mower without the maintenance, especially on hillier ground.
Consider this: The weight means it is not ideal if you need to lift it in and out of a vehicle regularly.
3. WORX Nitro Cordless Lawn Mower, 21″ Electric Mower with 2 × 5.0 Ah Batteries, WG752
A 20-inch cut and a smart motor that boosts power when the grass gets thick.
WORX’s Nitro mower uses AeroDeck Technology, which is a vented deck design that increases air volume to prevent clogs and clumping. It comes with two 20V 5.0Ah PowerShare Pro batteries that combine for a 40V system. The brushless motor 2.0 delivers 40% more power and 10% more runtime than first-gen brushless motors, according to the maker.
IntelliCut Technology uses sensors to automatically increase the blade speed in dense grass and conserve power in lighter areas. You get 7 positions from 1.5 to 4 inches. It weighs 55.6 pounds, which puts it in a middle ground between the lightest push mowers and the heavy self-propelled models. Buyers mention it is “quiet, efficient,” and that the “motor boosts in heavy grass.”
Unlike the CRAFTSMAN V20 which has a dual-lever height adjust, this WORX uses a single 7-position lever that is quick to set. It also has a fully collapsible handle for vertical storage.
what separates it
- IntelliCut adjusts power on the fly for thick patches
- AeroDeck reduces clogs and improves cut quality
- Collapsible handle for compact vertical storage
Limitations to know
- Batteries are a bit hard to remove, per some owners
- Replacement blades may not be widely available yet
Why choose this: For a yard up to half an acre where you want automatic power adjustment and minimal bagging clogs.
Who should pass: Anyone who needs replacement blades right now may find that frustrating in the short term.
4. CRAFTSMAN V20 20 in Lawn Mower, 2 x 5Ah Batteries and 2 Chargers, CMCMW220P2
A low-deck mower that slides under obstacles and stores up in a flash.
The CRAFTSMAN V20 push mower has a low-profile deck that measures only 10 inches tall at the lowest setting. This gives it enough clearance to reach under shrubs and around obstacles where bulkier mowers get stuck. It weighs 47.9 pounds, a solid mid-range weight for a 20-inch deck, and the vertical storage design takes up 78% less floor space.
It includes two 5Ah batteries and two chargers. The dual-lever height adjustment goes from 1.5 to 3.5 inches. Customers note it “mows 1/2 acre on one charge with 5AH batteries” and call it “much more powerful than expected.” One owner says it outperforms a 5 HP gas mower they previously owned.
The trade-off is at 47.9 pounds it is 47.9 pounds; the KraftSense mower is 26.4 pounds, so it is noticeably heavier to push around for a smaller person. Some users also note the blade speed is slower than gas, which can cause clogs in damp grass.
Reasons to pick it
- Very low deck height for close trimming around obstacles
- Vertical storage saves significant garage space
- Strong cutting power that some buyers compare favorably to gas
Where it struggles
- Heavier than some 20-inch competitors
- Blade speed drops below 20% charge, causing uneven cut
Best for: Someone who wants a powerful, space-saving mower that can reach under low-hanging branches and furniture.
Think twice if: You do not mow regularly — the torque drops off when grass gets tall or damp, causing wind-rows.
5. Greenworks 48V (24V x 2) 21″ Brushless Cordless Self-Propelled Lawn Mower, MO48L520
Twin 24V batteries combine into a 48V system that powers a 4-in-1 machine.
Greenworks takes a unique approach by using two 24V 5.0Ah USB batteries that work together to deliver 48V of power. This lets you stay on the 24V battery platform, which is compatible with over 200 other tools. The self-propelled rear-wheel drive with variable speed control gives you maximum traction on slopes.
The 4-in-1 system includes mulching, rear bagging, side discharge, and a turbo button for leaf pickup. The LED headlight is a nice touch, but one reviewer notes it “always on, can’t disable.” The runtime is up to 45 minutes with both batteries, which reviewers point out is closer to 30 minutes at a steady pace.
At 77 pounds, it is heavy, but the self-propel system makes it manageable. It offers 45 minutes of runtime versus the EGO’s 50 minutes, but the Greenworks gives you a 21-inch deck width and the 4-in-1 versatility at a lower price tier. Buyers appreciate the “lovely adjustability” of the speed control.
What you get
- 48V power from a common 24V battery platform
- 4-in-1 functionality including a turbo button for leaf pickup
- Self-propelled rear-wheel drive for better traction
Things to note
- Batteries take a long time to charge, per some owners
- LED headlight cannot be turned off
Ideal for: Those already invested in Greenworks 24V tools who want a heavy-duty mower that shares the same batteries.
One thing to watch: The runtime is lower than the EGO and SKIL, so plan a recharge if your yard is larger than a quarter acre.
6. KraftSense 18″ Electric Lawn Mower, 40V Cordless with 2×8.0Ah Batteries & Charger, X20SLM430DA
Big battery capacity at a lean price, with a smart USB-C port built into each pack.
The KraftSense mower packs two 8.0Ah batteries, which is a larger amp-hour capacity than the 5.0Ah packs found on many mowers in this price range. Each battery includes a USB-C port that lets you use them as power banks to charge your phone or other devices. At 26.4 pounds, it is 26.4 pounds (the CRAFTSMAN V20 weighs 47.9 pounds), making it one of the easiest to push for its 18-inch deck size.
The high-efficiency 3600 RPM brushless motor gives you a clean cut in one pass. You get 6 positions from 1 to 3 inches. The battery life is 45 minutes total, and buyers mention about 30-45 minutes of run time for a small yard. Some owners note the plastic parts feel less durable than metal alternatives, and the handle design requires unscrewing to collapse the Z-fold.
Compared to the WORX WG735, this KraftSense gives you an 18-inch cut (18 inches vs. 14 inches) and larger battery capacity — a better fit for a medium-sized lawn. The 3-year tool warranty adds confidence.
What makes it a value
- Two 8.0Ah batteries give the biggest total amp-hour capacity here
- USB-C ports on batteries double as power banks
- Very lightweight at only 26.4 pounds
Where it cuts corners
- Mostly plastic construction may not last as long as steel
- Batteries get hot and buzz while charging, a safety concern noted by some
A good fit for: A budget-conscious buyer who wants a lightweight mower with huge battery runtime and a handy USB-C feature.
Hold off if: You need a more durable deck and handle that will take heavy seasonal abuse over many years.
7. WORX Cordless Lawn Mower, 14″ Electric Mower with Brushless Motor, Lightweight Push Lawn Mower, WG735
A tiny 14-inch deck that slips past obstacles and into tight garden paths.
The WORX WG735 is the smallest mower here with a 14-inch cutting width — ideal for trimming under shrubs and along flower beds. It weighs only 27.71 pounds, light enough to use with one hand; one buyer says “you could push it with one finger.” The cut-to-edge design reaches closer to fences and borders, so you may need a separate trimmer less often.
It includes two 20V batteries that combine for 40V power, but the runtime is officially listed at mowing up to 1/8 acre on a single charge. One reviewer noted the “Battery lasted 45 min. with some battery left” on a 50×100 foot lot, which is a solid real-world result. The 6-position height adjustment goes from 0.8 to 3 inches.
The downsides are that the highest cutting setting is still too low for very tall grass, and the handle knobs stick out wider than the base, which can be annoying near walls. It is not the right tool for a large lawn, but for a small space it is nearly perfect.
Why it is great for small yards
- Extremely lightweight and easy to maneuver with one hand
- Cut-to-edge design reduces need for string trimming
- Very compact for easy storage
Its limits
- 14-inch deck means many passes on a medium yard
- Handle knobs protrude wider than the deck itself
Perfect for: Anyone with a very small yard, a townhouse patch, or lots of tight, obstacle-filled flower beds.
Not for: A quarter-acre or larger lot where the narrow deck would make the task overly time-consuming.
Understanding the Specs
Deck Size vs Yard Size
Deck width (14 to 21 inches) directly determines how many passes you make. A 14-inch deck will feel slow on a third-acre lawn but excels at tight spots. A 20- or 21-inch deck covers ground quickly but is heavier and wider, making it harder to maneuver around obstacles. Match deck size to your yard’s open area.
Battery Voltage and Amp-Hours
Voltage (V) affects how much torque the motor can produce for thicker grass. Amp-hours (Ah) is the fuel tank size. A 40V 6.0Ah battery holds more energy than a 40V 2.5Ah battery. Two 5.0Ah batteries double your total runtime. Check the Ah rating on any mower you consider — it tells you how much mowing you get per charge.
Self-Propelled vs Push
A self-propelled mower uses a drive system to pull itself forward, adjustable with a variable speed control. That saves effort on slopes and over longer distances. A push mower is simpler, lighter, and cheaper, and makes sense for flat, small yards where you do not mind the walk.
Height Adjustment Range and Positions
More positions (6 or 7) let you dial in the exact grass height for seasonal changes. A wide minimum-to-maximum range (like 1.5 to 4 inches) gives flexibility for everything from a golf-green look to taller, drought-tolerant grass. Single-lever adjustment is faster than individual wheel levers.
