How we chose these gas lawn mowers
We compared the listed engines, deck widths, drive types, cutting-height ranges and clipping options against common yard needs. Our score weighs specs, features and buyer feedback against what you’re shopping for.
A narrower deck can suit a small yard with tight turns, while a wider deck may cover more ground per pass. Clipping options also change how you manage grass after cutting: side discharge sends it back onto the lawn, while bagging collects it and mulching cuts it into smaller pieces.
The EGO picks are electric, so they aren’t gas lawn mowers. For another battery-powered option, compare Greenworks 80V lawn mowers.
For lighter battery-powered alternatives, see lightweight electric lawn mowers.
They’re included as alternatives for shoppers comparing a gas mower with a battery-powered walk-behind or riding mower. Makita lawn mowers offer another battery-powered lineup to compare.

PowerSmart EasyCut 18-Inch Gas Lawn Mower: Best for small yards
- 144cc 4-cycle engine
- 18-inch steel deck
- Side discharge
- Cutting height from 1.5 to 3.9 inches
Its compact 18-inch deck and side discharge suit smaller yards where a narrower push mower is easier to maneuver. The cutting height adjusts from 1.5 to 3.9 inches.
Pros
- 18-inch steel deck
- Side discharge for tall or thick grass
- Folds for compact storage
Cons
- No bag attachment
- Push mower
The PowerSmart EasyCut’s 18-inch steel deck makes it a compact option for smaller yards and tighter paths. Its 144cc four-cycle OHV engine uses an auto choke and primer structure for starting.
This mower discharges clippings to the side rather than collecting them in a bag. PowerSmart says the side discharge helps keep mowing through tall, thick grass, which may suit a lawn where clippings can stay on the ground.
The cutting height adjusts from 1.5 to 3.9 inches. Its 8-inch rear and 7-inch front wheels are intended to help with maneuvering around trees, flower beds and tight corners.
The mower folds down for compact storage in a garage or shed. Choose it if you have a smaller lawn and side discharge works for your routine; skip it if you need rear bagging.
SENIX Gas Lawn Mower: Best for a lightweight push mower
- 144cc 4-cycle engine
- 18-inch cut
- Three height settings
- Side discharge
This 18-inch SENIX push mower is described as lightweight and has a compact design for smaller yards. Its side-discharge tunnel spreads clippings across the lawn.
Pros
- 37.5 lb listed weight
- Ergonomic handle
- Three height settings
Cons
- Side discharge only
- Three height settings
The SENIX 18-inch push mower is a lightweight option for smaller yards, with a listed weight of 37.5 lb. It pairs a 144cc four-cycle engine with an 18-inch blade.
Its three cutting-height settings range from 1.2 to 3.15 inches. That gives you fewer positions to choose from than the PowerSmart, but the lower stated minimum may matter if you prefer a shorter cut.
Clippings leave through side discharge, with a vortex tunnel design intended to spread them evenly. The mower has 7-inch rear wheels and an ergonomic handle.
Choose this model if a lighter push mower and side discharge suit your yard. If you need mulching or bagging, look at a mower with those options, such as the BILT HARD 21-inch or SENIX 22-inch.
EGO Power+ 21" Cordless Electric Lawn Mower: Best gas alternative for wider cuts
- 21-inch cut
- Self-propelled drive
- Two 56V 6.0Ah batteries included
- Up to 100 minutes of runtime
This cordless EGO is an electric alternative for shoppers comparing gas mowers. It has a 21-inch cut, self-propelled drive, and interchangeable lower blades for mulching, high-lift bagging or extended runtime.
Pros
- Two batteries included
- Variable self-propel speed
- Eight cutting height positions
Cons
- Battery powered, not gas
- 96 lb listed weight
The EGO Power+ 21-inch is a battery-powered alternative for shoppers comparing gas and cordless mowers. It includes two 56V 6.0Ah batteries and has a self-propel system with variable speed from 0.9 to 3.1 mph.
EGO states that the mower runs for up to 100 minutes on one charge with the included batteries. Actual runtime can vary with mowing conditions, so consider your yard and charging routine rather than treating the maximum as a guarantee.
Its Select Cut system uses interchangeable lower blades for mulching, high-lift bagging and extended runtime. The mower also has eight cutting-height positions from 1 to 4 inches and LED headlights.
Choose it if you’re open to battery power and want self-propelled drive with multiple blade options. If you want a gas-powered mower, the BILT HARD or SENIX models below are closer matches.
BILT HARD 201cc Push Lawn Mower: Best for three clipping options
- 201cc 4-cycle OHV engine
- 21-inch steel deck
- Mulching, bagging and side discharge
- 10 cutting height positions
Its 21-inch deck offers three clipping options: mulching, rear bagging and side discharge. A single lever sets one of 10 cutting heights from 1.2 to 3.75 inches.
Pros
- Three clipping options
- 10 height positions
- No-choke, no-primer starting design
Cons
- Not designed for slopes over 15 degrees
- Push mower
The BILT HARD 21-inch push mower stands out for three clipping options: mulching, rear bagging and side discharge. Its 201cc four-cycle OHV engine and 21-inch steel deck suit buyers who want a wider cut than the 18-inch models.
A single lever adjusts cutting height across 10 positions, from 1.2 to 3.75 inches. The mower also has 9.5-inch rear and 8-inch front wheels, with a foam-wrapped angled grip.
BILT HARD describes its starting design as having no choke and no primer. The mower is not designed for hilly terrain or slopes over 15 degrees, so read its instructions and consider your lawn’s slope before buying.
Choose this mower if you want a push model with bagging, mulching and side discharge. If you prefer self-propelled drive, compare the SENIX 22-inch.
BILT HARD Gas Lawn Mower 20 inch: Best for eight height settings
- 144cc 4-cycle OHV engine
- 20-inch deck
- Eight cutting height positions
- Single-lever height adjustment
This BILT HARD push mower has a 20-inch deck and eight cutting height positions. Its single-lever adjustment ranges from 0.7 to 3.2 inches.
Pros
- 20-inch cutting deck
- Eight height positions
- No-primer, no-choke starting
Cons
- Side discharge and bagging options aren't specified
- Not intended for slopes over 15 degrees
The BILT HARD 20-inch gas mower offers a middle-width deck and eight cutting-height positions. Its 144cc four-cycle OHV engine has auto-choke starting with no primer or choke to operate, according to the product details.
A single lever adjusts the cutting height from 0.7 to 3.2 inches. The 20-inch deck is wider than the two 18-inch options, while its listed weight is 51 lb.
The clipping options aren’t specified here, so confirm that the mower handles your preferred method before buying. BILT HARD also says not to dump or turn the mower over, and the mower is intended for level ground rather than slopes greater than 15 degrees.
Choose it if the width and height range fit your lawn and the clipping setup works for you. If you need clearly stated bagging and mulching options, choose one of the three-in-one models instead.
SENIX 201cc 22" 3-in-1 Variable Speed Self: Best for self-propelled mowing
- 201cc 4-cycle OHV engine
- 22-inch steel deck
- Variable-speed self-propelled drive
- Mulching, bagging and side discharge
The 22-inch SENIX combines self-propelled rear-wheel drive with mulching, bagging and side-discharge modes. Its six height settings range from 1.25 to 4 inches.
Pros
- Self-propelled drive
- Three clipping options
- 11-inch rear wheels
Cons
- 79 lb listed weight
- Wider deck needs room to maneuver
The SENIX 22-inch is the self-propelled gas pick, with rear-wheel drive and variable speed. Its 201cc four-cycle OHV engine and wide steel deck are aimed at medium to large lawns.
You can switch among bagging, mulching and side discharge. A single lever sets one of six cutting heights from 1.25 to 4 inches, and the large 11-inch rear wheels are paired with the self-propelled drive.
The mower weighs 79 lb, which is worth considering for storage and transport. Its wide deck may also need more room around garden beds, gates and other obstacles than an 18-inch mower.
Choose it if self-propelled mowing and three clipping modes matter more than a compact mower. If you’re deciding between a PowerSmart model and other options, compare this guide with our best PowerSmart lawn mower picks.
EGO Power+ Electric Riding Lawn Mower: Best for large lawns without gas
- 52-inch zero-turn deck
- Six 56V 12.0Ah batteries included
- Cuts up to 4 acres on a charge
- 4 to 8 mph speed
This battery-powered zero-turn rider is a large-lawn alternative for shoppers comparing gas equipment. It has a 52-inch deck and six included batteries.
Pros
- 52-inch cutting deck
- Six batteries and charger included
- Up to 4 acres per charge
Cons
- Battery powered, not gas
- 527.4 lb listed weight
The EGO Z6 is a battery-powered riding alternative for large lawns. It has a 52-inch zero-turn deck, six 56V 12.0Ah batteries and a charger.
EGO says the mower can cut up to 4 acres on a charge with the included batteries. Its stated speed range is 4 to 8 mph, and the mower uses up to six EGO 56V ARC Lithium batteries.
This is a substantially different type of machine from a walk-behind gas mower. Its listed weight is 527.4 lb, so consider access, storage and transport before treating it as an alternative.
Choose it if you need a riding mower and want battery power. For a large gas walk-behind mower, the self-propelled SENIX 22-inch is a closer comparison.
How do you choose a gas lawn mower for your yard?
Choose a gas lawn mower by matching its deck, drive type and clipping method to your lawn. The right combination depends on how much area you mow, how tight the turns are and whether you collect clippings.
Is an 18-inch or wider gas mower better?
An 18-inch mower can fit smaller yards and tighter spaces, while a 20- or 21-inch deck cuts a wider strip each pass. The SENIX 22-inch goes wider still, but its larger deck may be harder to guide around narrow paths and obstacles.
Measure gates and storage openings before you decide. A deck that fits your lawn may still be awkward to store.
Do you need a push or self-propelled mower?
A push mower relies on you to move it forward. It can be a straightforward fit for a smaller, flatter lawn, while a self-propelled mower such as the SENIX 22-inch provides drive to help move the mower.
Think about your yard’s size, terrain and how you plan to steer and store the mower. For more on handling a mower, see How To Make A Racing Lawn Mower Cheap?.
That guide covers a different project, so follow the mower’s safety instructions and don’t modify a mower for normal lawn care.
Which clipping option should you pick?
Choose side discharge if you want clippings to leave the deck onto the lawn. Choose bagging if you want to collect them, or mulching if you want the mower to cut clippings into smaller pieces.
The PowerSmart and SENIX 18-inch models specify side discharge. The BILT HARD 21-inch and SENIX 22-inch list all three options, so they give you more ways to manage clippings.
What cutting-height range matters?
A mower with a wider adjustment range gives you more choice about the grass height you leave behind. The BILT HARD 20-inch range starts at 0.7 inches, while the SENIX 22-inch adjusts up to 4 inches.
Compare the stated range and number of positions rather than assuming that more settings always mean a better cut. Use the mower’s instructions to choose a safe height for your grass and conditions.
Is gas or battery power the better fit?
A gas mower is the direct choice if you want a small-engine mower. Battery-powered EGO models offer another route, with the walk-behind EGO including two batteries and the riding model including six.
Compare how much lawn you mow, the available storage and your preference for a walk-behind or riding mower. For an electric walk-behind with a starting feature, see best gas lawn mower with electric start, and check whether the models there meet your needs.
Final pick: Which gas lawn mower should you choose?
Choose the PowerSmart EasyCut if you have a small yard and side discharge is enough. Pick the BILT HARD 21-inch if you want bagging, mulching and side discharge, or the SENIX 22-inch if self-propelled drive is your priority.
Before buying, compare deck width with your tightest path and storage space. If your mower needs fuel removed for storage or service, read How to Drain Gas from a Lawn Mower? and follow the manufacturer’s safety instructions.

Frequently asked questions
What is the best gas lawn mower for a small yard?
The PowerSmart EasyCut 18-Inch is a strong fit for a small yard if side discharge meets your needs. Its 18-inch steel deck is narrower than the 20-, 21- and 22-inch options here, and the mower folds for compact storage.
The SENIX 18-inch push mower is another compact option, with a listed weight of 37.5 lb.
Should I choose an 18-inch or 21-inch gas mower?
An 18-inch mower can be easier to guide through tight areas, while a 21-inch deck covers a wider strip with each pass. Compare yard size, gates, trees and storage space before choosing.
The 18-inch picks here are push mowers with side discharge.
The 21-inch BILT HARD has mulching, bagging and side discharge.
Is a self-propelled gas mower worth considering?
A self-propelled mower moves forward under its own drive, so you guide it instead of supplying all the forward push. The SENIX 22-inch has variable-speed self-propelled drive, a 201cc engine and three clipping options.
Its 79 lb listed weight and wider deck may matter when storing or turning the mower.
Can I use a gas mower for mulching and bagging?
Some gas mowers offer both options, but the two 18-inch picks here specify side discharge only. The BILT HARD 21-inch and SENIX 22-inch include mulching, bagging and side discharge.
Choose a mower with the clipping method you plan to use, and check that the bag or other parts you need are included.
What should I check before buying a cheap gas lawn mower?
For a lower-cost gas lawn mower, compare the deck width, engine, cutting-height range and clipping options before focusing on price. A mower with side discharge only may not suit you if you need bagging.
Also check the storage footprint and the manufacturer's instructions for safe use on slopes.
