Whether you are dealing with a postage-stamp city lot or a sprawling suburban quarter-acre, a solid inexpensive lawn mower is about getting the most cut for your cash without the headaches.
Our Picks at a Glance
How To Choose The Best Inexpensive Lawn Mowers
An inexpensive lawn mower is a trade-off, but it shouldn’t be a bad one. The key is to find a machine that skips the unnecessary frills while keeping the essentials solid: a reliable engine or motor, a deck that won’t rust through, and a cutting width that matches your yard size. You don’t need a self-propelled drive or a digital display, but you do need something that starts consistently and cuts evenly.
Cutting Width vs. Yard Size
A wider deck means fewer passes, which means less time pushing. For a small yard under a quarter-acre, a 16-inch to 20-inch deck is perfectly fine. For anything larger, a 21-inch deck starts to make serious sense — you gain about 5% more cutting width per pass compared to a 20-inch, which adds up over the full lawn.
Power Source: Gas vs. Battery
You get consistent power for large or overgrown lawns with a gas mower, but you have to change oil, mix fuel, and pull-start it. Battery mowers are quieter, start instantly with a button, and need almost no maintenance — but you are limited by how long the battery lasts per charge. For a typical suburban lot, a 40V or 60V battery with a 4.0Ah (amp-hour) capacity or larger gives you the best balance of power and runtime. A 16-inch battery mower is lighter and easier to store, but it will take noticeably longer to cut the same area.

In‑Depth Reviews
1. SKIL PWR CORE 40 Brushless 40V 20-Inch Self-Propelled Mower
Our pick — 4.5★ from 150+ verified ratings; the strongest balance of quality and price.
The battery-powered self-propelled mower that leaves gas in the dust for small to medium yards.
This is the pick that makes you wonder why anyone still buys gas. The variable-speed self-propulsion lets you set your own walking pace, and the push-button start means zero pull-cord frustration. The digital brushless motor delivers efficient power without the noise or fumes of a gas engine. Buyers report the battery lasts about an hour, which is enough for a front-and-back yard with charge to spare — one reviewer noted it handles a third of an acre on a single charge.
The 7-position single-lever height adjustment covers a range from 1.5 inches to 4 inches, so you can go from a tight golf-course trim to a taller summer cut. The 20-inch cutting width is 5% narrower than the 21-inch mowers on this list, which means a few extra passes on a large lawn, but the self-propelled drive makes those passes feel easy. The folding handle makes vertical storage simple, saving garage space.
The one real trade-off is that it struggles with very tall wet grass — you will want to raise the blade height and take lighter passes. The self-propel mechanism is also noticeably louder than the motor itself, which some owners find surprising.
Why it wins
- Variable-speed self-propel adjusts to your walking pace
- Push-button start — no priming, no pulling
- Battery life is the most-praised feature, with owners reporting consistent runtime
The honest limit
- Struggles in very tall, damp grass — you need to raise the deck
- Self-propel drive is louder than the cutting motor
Reach for this if: you want a quiet, easy-to-use mower that pushes itself and is ready to go at the press of a button.
Look elsewhere if: your lawn is overgrown or larger than a half-acre — the battery may need a top-up mid-job.
2. SENIX 20″ Gas Lawn Mower, 144cc
The cheapest gas mower that actually starts on the first pull and cuts thick grass.
For the price, this SENIX delivers where it counts: the 144cc 4-cycle engine (a gas engine that uses straight gas, no oil mixing) starts easily and runs smoothly through thick grass and gentle slopes. The 20-inch cutting width is standard for the class, and the 3 cutting height positions range from 1.35 inches to 3.15 inches — but note that even the tallest setting produces a golf-course-fairway short cut, which may not suit everyone.
The 7-inch front and rear wheels glide over bumpy ground, and the 2-year warranty adds confidence at this price tier. Starting performance is the single most-praised aspect — buyers consistently report it fires up on the first pull after priming. However, the 3-position height adjustment is sparse compared to the 6- or 7-position competitors, and the tallest cut is still only 3.15 inches, which is 24% lower than the AMERISUN’s 3.9-inch max.
A minority of owners mention durability issues: some note that bolts loosened and fell out within weeks, requiring threadlocker to fix. This is a budget machine, so treat the hardware as user-serviceable.
Best for quick budgets: If you need a gas mower that starts reliably and covers a standard lot while staying affordable, this does the job. Just know you are trading height flexibility and long-term hardware tightness for the low entry price.
Grab it if: you keep a small, flat lawn and want the simplest gas mower that just works.
skip it if: you need a higher max cut or more height positions for uneven terrain.
3. AMERISUN 21-Inch Gas Lawn Mower, 144cc
A 21-inch gas mower that cuts as wide as models costing twice as much.
The AMERISUN’s biggest advantage is right there in the name: the 21-inch cutting deck. That extra inch over the 20-inch SENIX and SKIL mowers means you cover more ground per pass, which shaves real time off a medium-sized lawn. The 144cc 4-stroke OHV engine (overhead valve, a design that improves fuel efficiency and reduces emissions) delivers reliable power for regular residential mowing, and the 6-position height adjustment gives you a range from 1.5 inches up to 3.9 inches — a full 24% taller max cut than the SENIX 20-inch.
The 7-inch front and 10-inch rear wheels help roll over uneven ground without constant wrestling. The 2-in-1 functionality (mulching and side discharge) is straightforward, though it lacks a rear-bagging option if that matters to you. Owners consistently say it cuts as well as more expensive mowers they have owned in the past — a strong endorsement for the price.
A small number of units have arrived with broken tires, but the company responds by shipping replacements. The pull cord has also been reported to stick on a few machines, so inspect yours early within the return window.
The wide-deck winner: This is the cheapest way to get a 21-inch cut, and the height range is genuinely useful for seasonal lawn changes. The occasional quality-control hiccup is the trade-off for the low price.
Choose this if: you want the widest cut for the least money and a tall max height for summer grass.
Pass if: you need a bagging option or worry about receiving a defective unit.
4. PowerSmart 21-Inch Gas Lawn Mower, 144cc
The lightweight gas mower that outperforms pricier rivals on cut quality.
This PowerSmart stands out for its build and simplicity. The 21-inch all-steel deck is surprisingly light at 59.4 pounds, and the 144cc 4-stroke OHV engine with auto-choke starts reliably — customers note first-pull starts after seasonal storage. The 6-position single-lever height adjustment covers 1.5 inches to 3.9 inches, giving you the same wide range as the AMERISUN but in a lighter package.
The 10-inch rear wheels and 7-inch front wheels make it easy to maneuver on uneven terrain, and the 2-in-1 mulching and side-discharge system handles medium grass without clogging. One owner used it on a 4-acre property with heavy weeds and reported no grass buildup under the deck — a sign of good airflow design. The foldable handle saves up to 70% of storage space, which is a big deal for a garage with limited room.
Some owners note that the rear rubber flap rolls under the deck when reversing, and the side-chute is held by a spring that feels flimsy. These are minor but worth watching.
The lightweight workhorse: At this price, you get a 21-inch steel deck mower that starts easily and is light enough to push all day. The few plastic-component gripes are the only reminder it is a budget buy.
Perfect for: anyone who wants a reliable, manual gas mower that is easy to push and stores compactly.
Not for: overgrown lots — this is a weekly-maintenance machine, not a brush hog.
5. SENIX 21-Inch 2-in-1 Gas Lawn Mower, 144cc
Bigger wheels and a wider deck make this SENIX feel more capable than its price suggests.
This upgraded SENIX model brings two key improvements over the budget 20-inch version: a 21-inch cutting deck and an 8-inch front / 11-inch rear high-wheel system. Those larger wheels provide noticeably better traction and stability on uneven ground and slopes. The 144cc 4-cycle engine with 4QL lubrication technology is designed to run smoothly without mixing oil and gas.
The 6-position height adjustment ranges from 1.25 inches to 3.75 inches, which is a useful span for seasonal trimming. Tool-free assembly is a genuine time-saver — reviewers point out being ready to mow within minutes of unboxing. The mower comes with oil included, and most shoppers say it starts within three pulls. The 2-year warranty is standard for the tier.
There are reliability concerns: a few owners experienced the deck-height mechanism slipping to the lowest setting mid-mow, and one unit billowed smoke and died on first use. These appear to be isolated manufacturing defects rather than a design flaw, but they are worth noting.
The wheel upgrade: The larger wheels make a real difference on bumpy lawns, and the tool-free assembly is a genuine convenience. The occasional defect is the risk you take at this price point — buy from a retailer with a good return policy.
Ideal for: yards with uneven terrain where standard small wheels would bounce and struggle.
Hold off if: you need absolute reliability right from the start — inspect and test immediately.
6. Greenworks 40V 16″ Brushless Cordless Lawn Mower
The featherweight cordless mower that you can carry with one hand and store in a closet.
At 33.5 pounds, this Greenworks is the lightest mower in the lineup by a wide margin — you can literally carry it with one hand. The 16-inch cutting deck is noticeably smaller than the 21-inch competitors, which means more passes, but for a small city lawn or a tight backyard, the trade-off is worth it for the maneuverability. The brushless motor provides more torque and longer life than a brushed motor, and it runs quietly.
The 5-position height adjustment ranges from 1.25 inches to 3.38 inches, which is a narrower band than the 21-inch mowers but fine for regular weekly cuts. The 40V 4.0Ah battery delivers up to 30 minutes of runtime, and it fully charges in 120 minutes. The 2-in-1 mulching and rear-bagging system works well for small clippings. The folding handle makes vertical storage easy.
Battery life is the most frequently mentioned aspect, but the feedback is mixed — it works well for small yards but runs short on larger lots. Some owners noted the battery life drops in heat, so a second battery is a good idea for anything beyond a postage-stamp lawn.
What stands out
- Extremely light at 33.5 pounds — one-handed carry
- Quiet operation and zero maintenance compared to gas
- Folding handle for vertical storage in small spaces
What to watch
- 16-inch deck means more passes — slower on larger lawns
- Battery life is mixed; heat can reduce runtime
Perfect for: apartment dwellers with a tiny yard or anyone who needs a mower light enough to carry up stairs.
Not for: anyone with more than a quarter-acre — the small deck and limited runtime will frustrate.
7. PowerSmart 21-Inch 3-in-1 Self-Propelled Gas Lawn Mower, 170cc
The self-propelled gas mower that offers the most engine displacement for the lowest price on this list.
This PowerSmart is the only budget-tier mower here with a 170cc OHV engine, which provides a noticeable power advantage over the 144cc models. The 21-inch steel deck, 6-position height adjustment (1.5 inches to 3.9 inches), and 3-in-1 functionality (bagging, mulching, rear discharge) make it a versatile machine. The rear-wheel drive and 10-inch rear wheels give good traction on slopes.
Owners who get a good unit love it — they report easy assembly, first-pull starts, and powerful cutting through high grass. The self-propelled speed is fast enough to keep up with a brisk walking pace. However, this model has the lowest satisfaction rating in the lineup due to durability issues: some buyers report cheap plastic handle nuts breaking, handle separation, and rear tire bolts snapping after limited use.
The honesty here is important — the engine and cutting performance are genuine strengths, but the build quality of some components does not match. Inspect the hardware immediately and consider replacing plastic nuts with metal bolts proactively.
The power gambler: If you get a well-built unit, this is the most powerful self-propelled mower for the money. But the hardware quality is inconsistent, so check everything before your return window closes.
Try this if: you want a self-propelled mower with a big engine and are willing to tighten bolts and replace a few cheap parts.
Avoid if: you want a “set and forget” machine that will not need early DIY maintenance.
8. WORX Nitro Cordless Lawn Mower, 40V 21″
The cordless mower with smart cutting tech that adjusts power to the grass density in real time.
The WORX Nitro brings genuine innovation to the budget battery category. Its IntelliCut technology uses sensors to automatically increase blade speed in thick grass and dial it back in thinner areas to conserve battery. The AeroDeck vented design boosts air volume to prevent clogs and improve cut quality. The 40V system runs on two 20V 5.0Ah PowerShare Pro batteries, giving you up to 50 minutes of runtime — enough for a half-acre lawn.
The 7-position height adjustment ranges from 1.5 inches to 4 inches, matching the SKIL for the widest height range in the battery category. The 3-in-1 functionality (mulch, bag, side discharge) covers every clippings-handling need. At 55.6 pounds, it is heavier than the Greenworks 40V but still manageable. The dual fast charger is a nice touch — both batteries charge simultaneously.
Battery life draws mixed reactions: most owners mention it lasts through a full medium-sized yard, but a minority find it insufficient. The instructions manual is poorly written, which some owners found frustrating.
The smart cordless choice: The IntelliCut and AeroDeck features genuinely improve cut quality and runtime efficiency. It is 40V battery mowing at its most refined — just be ready for so-so instructions.
Go for this if: you want a battery mower with self-adjusting power and enough runtime for a half-acre.
Sit it out if: you need a self-propelled drive or dislike reading poor manuals to configure your tools.
9. Greenworks 60V 21″ Push Lawn Mower, 5.0 Ah
The 60-volt cordless mower that matches a 150cc gas engine’s blade speed without the fumes.
This Greenworks 60V model is the most powerful battery mower in the lineup. It delivers 50% more torque than 40V mowers and spins the blade at 3200 RPM — matching the cutting speed of a 150cc gas mower. The 21-inch deck makes it a direct peer of the gas-powered 21-inch models in terms of coverage, but you get push-button start, zero gas, and near-silent operation.
The 7-position height adjustment spans from 1.5 inches to 4 inches, and the oversized 10-inch rear wheels and 8-inch front tires make it easy to roll over uneven ground. LED headlights let you mow in early morning or late evening. The 5.0 Ah battery delivers up to 60 minutes of runtime, which is the best in the battery category here. The 4-year tool and 4-year battery warranty is the longest coverage on this list — a strong sign of confidence in the build.
At 59.5 pounds, it is the heaviest push mower (non-self-propelled) in the roundup, which some owners note. The battery and charger are also proprietary to the Greenworks 60V ecosystem, so you are locked into that platform if you expand your tool collection.
Why it leads battery class
- 60V power matches gas 150cc blade speed — 3200 RPM
- 60-minute average battery life is the best runtime here
- 4-year tool and battery warranty is the longest coverage offered
One honest trade-off
- Heavy for a push mower at 59.5 pounds — no self-propel option
- Locks you into the 60V Greenworks battery platform
Pick this if: you want gas-level cutting power without gas, and you have the space to push a heavier mower across your lawn.
Think twice if: you have a hilly yard that demands self-propulsion — you will burn out pushing this uphill.
Understanding the Specs
Cutting Width
This is the size of the mowing path in inches. A 21-inch deck covers more ground per pass than a 16-inch deck, so you finish faster on a medium lawn. For a small yard under a quarter-acre, a 16-inch or 20-inch deck is fine. For anything larger, a 21-inch deck makes a real time difference over the full mow.
Height Positions & Range
Height positions let you choose how short or tall the grass stays after a cut. More positions (6 or 7) give you finer control, while the range (measured in inches) tells you the lowest and highest possible cut. A range from 1.5 inches to 4 inches covers most seasonal needs — lower in spring for a tidy trim, higher in summer to shade the soil and retain moisture.
Self-Propelled vs. Push
A self-propelled mower drives itself forward so you just walk behind it — great for slopes or larger lawns. A push mower requires you to provide all the forward force, which is fine for small flat yards but becomes tiring on hills or long mows. Self-propelled models cost more and add mechanical complexity that can fail over time.
Battery Voltage & Capacity
Voltage (V) roughly correlates with power — 60V mowers deliver more torque than 40V models. Capacity (Ah) determines runtime. A 4.0Ah battery lasts longer than a 2.0Ah battery at the same voltage. For a typical suburban yard, look for at least a 4.0Ah battery in a 40V system or a 5.0Ah battery in a 60V system to avoid running out mid-lawn.

Final Thoughts: The Verdict
For most people, the inexpensive lawn mower winner is the SKIL PWR CORE 40 because it combines self-propulsion, push-button start, and genuine battery endurance in a package that makes mowing feel easy. If you want the widest cut for the lowest price, grab the AMERISUN 21-Inch Gas. And for a powerful battery mower that runs as long as a full hour, the Greenworks 60V 21-inch is the one to reach for.
