Our top picks

Side by side

Spec comparison

This is the budget where you stop pushing the whole mower yourself. Self-propel, a full-size deck and a real engine or battery turn mowing from a chore into a routine, and the choice becomes how you want to power the wheels and the blade. A mower at this level should still feel like a good tool in year ten.

The cap here is $500, and prices move, so it reflects listing prices when this guide was updated. The decision is between a gas engine, which is cheap to buy and easy to refuel, and a premium battery system, which costs more to enter but little to run.

Before you buy

6 Criteria to Look For Before Buying a Lawn Mower Under $500

  1. 01

    Self-propel is the main upgrade

    A self-propelled mower drives its own wheels and takes the push out of slopes and full bags. Rear-wheel drive, on the PowerSmart pair and the Greenworks 60V, gains traction uphill. On a battery mower self-propel draws from the same pack, so acreage per charge drops. Test drive any self-propelled mower in a store to feel whether the speed control suits you. Rear-wheel drive also helps when the bag is full and the rear is heavy. Self-propelled models are also heavier, which matters when you load them into a truck or trailer.

  2. 02

    Torque versus horsepower

    The EGO quotes up to 6.0 ft-lbs of cutting torque, which is the number that matters in thick grass. A 170cc gas engine produces roughly four to five horsepower gross. Compare torque or blade-speed hold under load, not just engine displacement. Blade tip speed and deck shape affect lift as much as torque numbers. Premium battery mowers hold blade speed well because their controllers manage load. Gas engines hold a consistent speed, while batteries sag slightly as they drain.

  3. 03

    Gas versus premium battery

    A gas mower costs less to buy but needs oil, plugs and fuel stabilizer each year. A premium battery mower like the EGO or Greenworks 60V costs more up front but almost nothing to run. Over ten years the totals are close. The best choice is the one you will actually maintain. An easy-start gas mower beats a theoretically better one that sits unused. If you dislike maintenance chores, the battery path is worth the premium.

  4. 04

    Deck width

    A 22-inch deck covers about 5 percent more than 21 inches. Wide decks mean fewer passes but are harder to turn in tight yards. For half an acre the difference is a few minutes. Measure your slowest, tightest turn before choosing a wide deck. Wider decks may not fit through a standard gate. Rain damp lawns need a slower pace and a higher deck.

  5. 05

    Runtime honesty

    The EGO claims up to 55 minutes. Runtime depends on grass height, dampness and slope. Expect 15 to 20 percent less in thick growth and more reduction with self-propel. A second pack is worth the cost on a half-acre lawn. On a hot day a lawn takes longer to cut, so runtime drops. Leaves and heavy thatch cut runtime more than grass does.

  6. 06

    Discharge flexibility

    The SENIX 3-in-1 and Greenworks 4-in-1 mulch, bag or side discharge. Mulching saves emptying but needs frequent cuts. Bagging costs runtime on battery mowers. Bag only when you must; mulching clippings feeds the lawn. Dry grass mulches best, wet grass clumps. Always check that the discharge chute is clear before starting.

Detailed reviews

The 5 best lawn mowers under $500, explained

01
EGO POWER+ 21-Inch Cordless Electric Lawn Mower LM2114
56V class21 in deck55 min7 heights
Check price on Amazon
Best for: Quarter-acre flat lawns where torque, quiet and a big platform matter.

The EGO LM2114 is a 21-inch cordless mower claiming up to 6.0 foot-pounds of cutting torque, the figure the listing uses to say it exceeds gas, and up to 55 minutes of runtime on a single charge. Torque at the blade, not horsepower, is what keeps the blade spinning in thick grass, and a high figure here means the mower holds speed when the deck loads up.

Seven cutting height positions give finer control than the five and six step levers on most rivals. A battery and charger come in the kit, and the EGO battery platform is one of the largest in cordless outdoor tools, so a trimmer, blower or hedge trimmer can share the pack.

Compared with the Greenworks 60V, the EGO is a push mower rather than self-propelled, so it suits flat to gently sloping lawns of a quarter acre or less. Runtime claims assume light, dry grass, so expect 15 to 20 percent less in thick growth. Rinse the deck, keep the battery indoors and replace the pack in around five years. Compared with a gas mower, the weekly routine is simpler: pull the battery, mow, rinse, recharge. Keep the pack at room temperature before charging, and the platform will repay the premium over many seasons.

What works

  • Up to 6.0 ft-lbs of cutting torque
  • Up to 55 minutes of runtime claimed
  • Seven cutting heights
  • Battery and charger included

Watch out for

  • Push mower, not self-propelled
  • Premium entry cost compared with gas

PowerSmart EasyDrive Pro 22-Inch 170cc Self-Propelled Gas Mower
170cc OHV22 in deckRear-wheel driveSteel deck
Check price on Amazon
Best for: Half-acre lawns with slopes or thick grass.

The PowerSmart EasyDrive Pro adds a 170cc four-stroke OHV engine, rear-wheel self-propel and a 22-inch steel deck. Rear-wheel drive gives better traction on slopes and uneven ground than front-wheel systems, because the weight transfers to the driven wheels as you push uphill.

A 22-inch deck is the widest in this lineup, and 170cc is a notch above the 144cc engines in cheaper tiers, with a stated capacity for thick grass. Together they cut a half-acre lawn in far fewer passes than a push mower, and self-propel takes the work out of slopes and bagging.

Gas upkeep is the cost: oil each season, a plug and air filter each year, and stabilizer before winter. Rinse the underdeck and dry the steel after each cut to slow rust. For large, uneven or sloped lawns, this is the heavy hitter. At year three, check the self-propel cable and wheel gears, since those are the parts that wear on a driven mower. The extra width helps most on long straight runs, so measure your yard before assuming you need it.

What works

  • Rear-wheel self-propel for slopes
  • 22 inch steel deck is the widest here
  • 170cc OHV engine
  • Handles thick grass

Watch out for

  • Needs seasonal oil and plug service
  • Heavier to store than battery mowers

170cc OHV21 in deckRear-wheel driveAuto choke
Check price on Amazon
Best for: Slopes and medium lawns where the 22 inch model is more than needed.

This PowerSmart 21-inch is the slightly cheaper sibling of the 22-inch EasyDrive Pro, with the same 170cc OHV engine, rear-wheel drive and steel deck, and an auto choke with recoil start. The one-inch narrower deck covers about 5 percent less per pass, which is hardly noticeable.

For most owners it is the better buy: nearly identical engine and drive at a lower price tier. An auto choke removes the manual choke step that trips new gas mower owners.

Same upkeep as the 22-inch: seasonal oil, yearly plug and filter, stabilizer before storage, and dry the deck after cutting. A second battery is not needed because the engine is gas, which is a quiet advantage on a large lawn. For most households this is the sweet spot: the same engine class as the bigger sibling at a gentler price.

What works

  • 170cc engine with rear-wheel drive
  • Auto choke for easier starts
  • 21 inch deck is a common size
  • Lower cost than the 22 inch model

Watch out for

  • Same gas upkeep as every gas mower
  • Steel deck can rust if left wet

SENIX 21-Inch 144cc Gas Push Lawn Mower, 3-in-1
144cc21 in deck6 heights3-in-1
Check price on Amazon
Best for: Flat lawns where gas runtime and 3-in-1 flexibility matter.

The SENIX 21-inch is a push mower with a 144cc four-stroke OHV engine, a high-strength steel deck, six height positions on a dual lever and 3-in-1 functions: mulch, bag or side discharge. The engine and deck are described as designed for longer life and low vibration.

Without self-propel, it relies on you to push the weight, which matters on slopes and with a full bag. Against the PowerSmart self-propelled models it saves money and weight but not effort.

It suits flat lawns where you want gas runtime and flexible discharge. Change the oil and plug on schedule and clean the deck after each cut. If you later move to a hillier property, this is the mower that won't hold you back. Treat the 3-in-1 as a seasonal tool: mulch in summer and bag in autumn leaf season.

What works

  • 3-in-1 mulch, bag and side discharge
  • Dual-lever six-position height
  • 144cc OHV engine
  • Lighter than self-propelled models

Watch out for

  • No self-propel, so slopes and bags are work
  • Needs seasonal gas upkeep

Greenworks 60V 21-Inch Self-Propelled Mower, Two 4.0Ah Batteries
60V brushless21 in deckSelf-propelled4-in-1
Check price on Amazon
Best for: Sloped lawns where you want self-propel without gas.

The Greenworks 60V pairs a brushless motor with rear-wheel self-propel and two 4.0Ah batteries, in a 21-inch deck with 4-in-1 functions. The listing says it handles slopes and thick grass and runs about three times quieter than a gas mower, with instant starts and zero emissions.

Self-propel draws from the same battery, so a self-propelled model gets less acreage than the push version on the same pack, and two batteries are what keep it practical. The 60V label is a platform name; a 60V max pack is about 54 volts nominal.

Against the EGO it adds self-propel but costs a little more and offers fewer heights, and it connects to the broader Greenworks 60V family. Rinse the deck and keep the packs indoors. Over several seasons, check the drive belt equivalent on the wheel assembly and keep the packs partly charged. The self-propel speed control matters for comfort, so test that it matches your walking pace.

What works

  • Rear-wheel self-propel on a battery mower
  • Two 4.0Ah batteries included
  • Brushless 60V motor
  • About three times quieter than gas

Watch out for

  • Self-propel reduces acreage per charge
  • Premium entry cost compared with gas

Methodology

How We Evaluated These Lawn Mowers Under $500

Drive and traction

We credited rear-wheel self-propel on slopes, listed on the PowerSmart pair and Greenworks 60V. Drive type was weighted heavily for sloped lawns. Wheel drive layout was checked from the listing description.

Power and torque

We compared engine size and the EGO's torque figure. Torque was credited when the listing stated it and discounted when it was only horsepower.

Runtime and upkeep

We weighed claimed runtime against gas service needs. Runtime claims were reduced by a margin before comparing.

Deck and discharge

We compared deck widths and discharge modes. Discharge modes were counted from the listings. Discharge flexibility was scored for what the listing states.

Owner feedback patterns

We evaluated patterns on hard starts, fading packs and self-propel belt wear. Complaints about self-propel cables shaped the maintenance schedule. Self-propel wear was listed as a medium-term cost.

For Half-Acre Lawns Specifically

Look for

Self-propel, a 21 to 22 inch deck and unlimited runtime. Battery mowers need a second pack at this size.

In this comparison

The PowerSmart 22-inch 170cc is the best fit; the 21-inch is the cheaper alternative.

When to Spend More

Spend more if

Your lawn is large, hilly or you want the EGO torque, which means the upper tier.

Save if

Your lawn is flat and under a quarter acre, where the SENIX suffices.

Ownership

Maintenance schedule

The upkeep that decides whether this machine lasts two seasons or ten.

TaskIntervalWhy it matters
Change oil and plug (gas)Each seasonOld oil and fouled plugs cause hard starts. Warm the engine before draining. Dispose of old oil at a recycling point.
Stabilize fuel (gas)Before winterStale gasoline gums the carburetor. Use fresh gas bought within the last month. Store the mower level so oil stays in the sump.
Sharpen or replace bladeYearlyA dull blade tears grass and strains the engine or battery. Sharpen both edges evenly to avoid vibration. Use a torque wrench on the blade bolt.
Check self-propel driveEach seasonBelts and cables stretch and slip. Adjust the cable only to the manual's spec. A quick test on a slope shows whether the drive slips.
Store battery indoors (electric)Off seasonTemperature extremes degrade lithium cells. Charge to half before long storage.

FAQ

Frequently Asked Questions

Is self-propel worth it?

On slopes, big lawns or with a bag, yes. On small flat lawns it adds cost without much benefit. A slope steeper than about fifteen degrees is better handled by rear-wheel drive. Test drive to feel the speed control. Most owners notice the difference within the first season.

Is a 170cc engine better than 144cc?

It has more reserve for thick grass and slopes, at slightly more fuel use. The bigger engine helps in thick grass and uphill. Both are fine for suburban lots, so the difference mostly shows on thick or hilly ground. For flat lawns, 144cc is plenty and cheaper to run.

What does $500 buy?

Self-propelled gas mowers or premium battery models. Prices move and the cap reflects listing prices when this guide was updated. Check the listing against the cap on the day you buy. Battery models are quieter and cleaner at the cost of a bigger entry price. Keep the receipt in case of warranty questions.

How long do premium batteries last?

Around five years, depending on cycles and storage. Batteries have a finite cycle life, so plan for a replacement. Anyone who rarely mows may do better with a gas mower. Keep spare packs at a moderate charge.

Can battery mowers match gas?

On torque, yes. On runtime for large lawns, a second pack is needed. Anyone with a large lawn needs a spare pack for a battery mower. Two packs let you swap midway with no waiting.

How do I store a gas mower for winter?

Add stabilizer, run the carburetor dry or drain fuel, change oil and store level. Run the engine until the tank is dry for the quickest winter prep. Fresh fuel also makes the engine easier to start. Do not store the mower tilted with the carburetor side down.
