Choosing a mower under $400 usually comes down to yard size, power source, and how much storage space you have. A gas push mower can make sense for thicker grass and larger lots, while a cordless or corded pick often suits smaller lawns and tighter storage. You want the machine that matches your grass, your pace, and how much upkeep you’re willing to handle.

More Details On Our Top Picks
That 21-inch deck gives you a wider path than the 18-inch models below, so fewer passes are needed across open lawns. The 144cc four-stroke OHV engine, meaning an overhead-valve design built for efficient airflow, suits homeowners who want a straightforward gas push mower without extra complexity.
The steel deck adds a sturdier feel than plastic-bodied cordless picks, though it also means a bit more heft to manage around tight corners. For medium yards with mixed grass conditions, this one makes sense for you more than a compact electric mower would.
Strong Points
- 21-inch cutting width helps cover more ground with fewer overlaps.
- 3-in-1 setup gives you mulch, bag, or side discharge options.
- Steel deck brings a solid feel for regular outdoor use.
- Gas power suits thicker grass and larger suburban lawns.
Things To Consider
- Push-only operation asks more from you than a self-propelled mower.
- Steel construction usually means more effort moving it in and out of storage.
- Gas ownership brings the usual upkeep, including fuel and routine attention.

Homeowners with medium to larger lawns and no interest in battery charging will get the most from this setup.
A Better Fit Elsewhere
PowerSmart EasyCut 18-Inch Gas Lawn Mower suits you better for a smaller yard where a lighter deck matters more than cutting width.
Small yards and mixed-use spaces are where this 13-inch cordless mower starts to make sense, especially when storage space is tight. The included 4.0Ah battery, meaning a 4 amp-hour pack that stores a useful amount of energy, gives you a self-contained setup without a cord trailing across the lawn.
Compared with the gas mowers in this list, it trades raw cutting reach for easier handling and a quieter-feeling routine. That makes it a friendlier choice for townhomes, side yards, and homes where you want less fuss between the garage and the grass.
Positives
- 13-inch deck stays nimble around narrow paths and obstacles.
- Cordless setup removes extension-cord management from the job.
- 5 height settings let you adjust for seasonal grass changes.
- Lightweight build helps during lifting, turning, and storage.
Points To Note
- Smaller deck means more passes on wider lawns.
- Battery runtime matters more here than it does on corded or gas models.
- Very dense grass can call for slower mowing pace.
Core Details
Built With In Mind
Apartment patios, townhomes, and small suburban lawns are the best match for this lighter cordless format.
Another Choice May Suit
DOVAMAN 13 Amp 16″ Lawn Mower works better for you when a cord is fine and bagging with a larger collection bag matters more than battery convenience.
This 18-inch layout feels like the middle ground in the PowerSmart lineup, narrower than the 21-inch EasyGlide but less bulky for smaller lawns. The 144cc four-cycle engine, which uses a separate combustion and exhaust cycle for steady operation, points toward a familiar gas-mower experience with side discharge only.
For small yards with regular trimming, that simpler setup is easy to understand and easy to live with. You may find the narrower cut especially helpful along fences, beds, and side strips where a wider deck can feel a little clumsy.
What We Like
- 18-inch deck keeps the mower more manageable than 21-inch gas models.
- Side discharge helps move clippings away during faster mow sessions.
- 5-position height control gives you basic cut flexibility.
- Gas power suits yards where charging time is not part of the routine.
Minor Gripes
- Side discharge only leaves you without mulching or bagging choices.
- Push design asks more physical effort than assisted walk-behind systems.
- Gas care and storage take more attention than a cordless mower.

Who Will Love This
Owners of smaller suburban lawns who want gas power without the bulk of a 21-inch deck will feel at home here.
Where A Sibling Pick Shines
PowerSmart EasyGlide 21-Inch Gas Lawn Mower makes more sense for you when the lawn is larger and cutting width matters more than maneuvering ease.
The adjustable handle and lighter frame make this one feel aimed at comfort first, especially for older adults or anyone who dislikes wrestling a heavy mower. The brushless motor, meaning the motor skips carbon brushes for less internal wear, is a useful detail for long-term simplicity rather than flashy power bragging.
Against the gas units above, this mower leans into easier pushing and less maintenance overhead. The 1 to 2.5 inch cutting range also suits tidy lawns more than rough, overgrown patches, so the honest read is that it fits regular upkeep better than rescue jobs.
Upsides
- Lightweight build helps reduce strain during push mowing.
- Adjustable handle supports a more natural mowing stance.
- Brushless motor usually means less wear than brushed designs.
- 5.0Ah battery gives you a practical cordless starting package.
- Narrow width works well in small urban yards and side areas.
Softer Spots
- 14-inch deck means more passes on medium lawns.
- Cut height range is tuned for trimmed grass, not tall overgrowth.
- Battery-powered mowing still depends on charging and storage habits.
Quick Facts
Right Fit For
Older adults, smaller-yard owners, and anyone who wants a lighter push mower with a calmer feel will appreciate this layout.
Swap It Out When
AMERISUN 21″ Gas Lawn Mower works better for you if your lawn runs larger and you want broader coverage with each pass.
Electric corded mowers only make sense for certain yards, and this DOVAMAN fits that narrower lane well. The 13-amp motor, meaning the tool draws power from a standard household corded setup, removes battery charging from the equation, while the 13.2-gallon bag gives you a generous place for clippings.
The quick vertical fold storage is especially handy in a garage that already feels crowded, and the 16-inch deck keeps the footprint reasonable. Compared with the cordless Litheli options, this one asks you to manage a cord, yet it rewards you with a more continuous mowing routine.
Best Bits
- 13-amp corded power avoids battery charging downtime.
- 13.2-gallon bag supports longer runs between emptying.
- Quick fold storage helps in cramped sheds or garages.
- 2-in-1 setup gives you mulching and bagging flexibility.
Worth Noting
- Cord management matters across the whole mowing path.
- 16-inch deck is practical, though not especially broad.
- Bagging means occasional cleanup and emptying during use.
Feature Rundown
The Right Fit
Homeowners with a reachable outlet and a modest yard will get the most from this corded format.
Look Elsewhere When
Litheli Cordless Lawn Mower 13 Inch U20 Handy+ is easier to live with for yards where cord handling would feel awkward.
Among the gas options here, this AMERISUN stands out for combining a 21-inch deck with a steel body and full 3-in-1 cut handling. That means you can mulch, bag, or use side discharge depending on season and cleanup habits, which matters in a yard that changes from week to week.
The 144cc four-stroke engine keeps it in the same general class as the PowerSmart EasyGlide, though the exact balance here leans a bit more toward broad coverage and straightforward durability. For homeowners with larger lawns who still want a push mower, that combination usually feels practical rather than fancy.
Highlights
- 21-inch width helps cover broad lawns efficiently.
- Steel deck adds a durable feel for recurring use.
- 3-in-1 clipping options keep the mower flexible.
- 6 cutting heights help match grass conditions across seasons.
Areas To Watch
- Push format still means full manual effort from you.
- Steel build may feel less nimble in very small yards.
- Gas upkeep remains part of ownership over time.

Whose Shelf It Belongs On
This suits owners with larger yards who want a broad gas mower and can handle the upkeep that comes with it.
Reach For A Different Pick When
PowerSmart EasyCut 18-Inch Gas Lawn Mower is the easier match for tighter lawns where a smaller deck brings better maneuverability.
This version of the EasyCut keeps the same 18-inch, small-yard-friendly footprint but adds a dual-lever height system. Dual-lever control means you adjust both sides more evenly, which can make the setup feel less fussy than a single-point style on uneven grass.
Compared with the earlier PowerSmart 18-inch model, this one leans a little more toward adjustment convenience than clip collection flexibility. That trade-off works nicely for simple trim jobs, especially when you value straightforward handling over extra mowing modes.
Bright Spots
- 18-inch deck stays easy to steer in smaller yards.
- Dual-lever height adjustment helps keep the cut even.
- Steel deck gives the mower a firmer outdoor work feel.
- Side discharge suits quick mow-and-move sessions.
Room For Improvement
- Side discharge only limits clippings-management choices.
- Push mowing still asks for full effort on your part.
- Gas storage and routine care add maintenance chores.

This fits small-yard owners who want a plain, dependable gas mower with easy height adjustment.
Where A Sibling Pick Shines
PowerSmart EasyGlide 21-Inch Gas Lawn Mower suits you better when you want broader coverage and the larger 3-in-1 setup.
This KOMASTY package brings a lot into a cordless format, including two 4.0Ah batteries, two chargers, and a 10.6-gallon bag. That bundle matters in real life because it reduces the amount of extra gear you need to source before mowing starts to feel convenient.
Compared with the smaller Litheli cordless model, it gives you a wider 16-inch deck and more accessory support out of the box. You may find it especially appealing for a small lawn where battery swapping and tidy clipping collection both matter.
Positives
- Two batteries and two chargers simplify the first setup.
- 16-inch cutting width is practical for small lawns.
- 2-in-1 mulching and bagging give you basic versatility.
- 5 height settings help you fine-tune the cut.

How To Choose The Right Lawn Mowers Under 400
Match Power To Your Yard
Gas mowers still make the most sense for thicker grass, uneven growth, and larger lawns where you want steady cutting power. The trade-off is upkeep, fuel handling, and more noise than a battery or corded option.
Cordless mowers suit smaller properties, simple weekly trims, and homes where storage space matters. Corded electric models work well too, as long as your yard layout lets you move comfortably without dragging the cord through every turn.
Think About Deck Size And Maneuvering
A 21-inch deck helps you cover more ground, which is useful on open lawns and wider stretches beside driveways. An 18-inch or 16-inch deck often feels easier around beds, fences, and narrow side yards.
Smaller decks can mean more passes, but they also reduce the feeling of wrestling a bulky machine. That balance matters more than many people expect once you start mowing around corners and edging obstacles.
Look Closely At Cut Adjustment And Clippings Control
Height settings let you adapt to seasonal growth and different grass types, so that range is worth real attention. A mower with mulch, bag, and side discharge gives you more control than a single-output model, especially during peak growing season.
Bag capacity also changes the day-to-day feel. A larger bag cuts down on emptying stops, while a smaller setup may be lighter to push but asks for more cleanup breaks.
Storage And Maintenance Matter More Than You Think
Foldable handles, lighter frames, and compact widths can save you from storage headaches in a crowded garage or shed. Corded and cordless mowers usually fit that kind of home better than a heavy gas machine, though gas models often reward you with more cutting authority.
Routine care deserves a seat at the table too. Gas mowers need more attention between fuel, engine upkeep, and general cleaning, while electric models usually keep ownership simpler but still benefit from battery care and debris removal.
Things Worth Knowing Before You Choose
Wrong Turns To Avoid
Many shoppers focus only on cutting width and miss the part where the mower actually fits the yard. A 21-inch deck sounds efficient, yet it can feel awkward in narrow side lawns or around dense landscaping.
Another common slip is overlooking storage. A mower that folds neatly or weighs less can save you far more frustration than a slightly bigger cutting path.
The Upgrade Payoff
More expensive mowers in this range usually pay for stronger materials, extra cutting modes, larger batteries, or more refined controls. You also tend to get better comfort touches, like a more adjustable handle or a larger grass bag.
That extra spend makes sense for larger lawns, frequent mowing, or long-term ownership where convenience matters more than bare minimum function. For a tiny yard, a simpler model often does the job without asking for extra features you won’t use.
Frequently Asked Questions
Are gas mowers still worth it under $400?
Gas mowers still fit larger yards and thicker grass very well. They ask for more upkeep than cordless or corded models, though.
Is a cordless mower enough for a small yard?
Yes, a cordless mower often works very well for small lawns and quick weekly trims. Battery runtime and deck size matter most in that setup.
What deck size works best for tight spaces?
A 13-inch to 16-inch deck usually feels easier in narrow areas and around landscaping. Wider decks suit open lawns better.
Do corded electric mowers save much hassle?
They remove charging and fuel concerns from the picture. The cord itself becomes the main trade-off during use.
What matters more than engine size?
Deck width, height adjustment, and grass-handling options often affect everyday use more than the engine number alone. Your yard layout should guide the choice first.
