Our picks for the best gas powered self propelled lawn mower, from a budget PowerSmart to a variable speed YARDMAX, plus a buying guide.
Pushing a heavy mower across a big or sloped lawn every week wears you out fast, and battery mowers can run out of charge before the job is done. The best gas powered self propelled lawn mower solves both problems: the engine drives the wheels so you only steer, and a tank of fuel keeps it running as long as your yard needs. To find the strongest options, we compared engine size, drive system, deck width, cutting modes and height range, read verified owner feedback on Amazon, and weighed each mower's price against what it delivers.
Our top three are the PowerSmart 21 inch 170cc as the best overall value, the YARDMAX 22 inch 201cc Select PACE as the premium pick with a variable speed transmission, and the PowerSmart 22 inch 170cc High Wheel as the runner up for rough, uneven yards.
Our Top 3 Picks at a Glance
- Best Overall: PowerSmart 21" 170cc Self Propelled Gas Mower (around $300). Rear wheel drive, a steel deck and 3 in 1 mulching, bagging and side discharge for a very low price.
- Best Premium Pick: YARDMAX 22" 201cc Select PACE 6 Speed Self Propelled Gas Mower (around $360). A bigger 201cc engine, a 6 speed CVT that matches your walking pace, and a wider 22 inch cut.
- Runner Up: PowerSmart 22" 170cc High Wheel Self Propelled Gas Mower (around $340). High rear wheels and rear wheel drive roll over bumps, with a wide 22 inch deck for faster mowing.
How We Chose the Best Gas Powered Self Propelled Lawn Mower
We focused on what matters for gas walk behind mowers: a reliable OHV engine, a drive system that handles your terrain, a sturdy steel deck, useful cutting modes and easy height adjustment. We then looked at owner ratings and the size of each review base, price versus features, build quality and warranty, and whether each mower is currently sold new on amazon.com. Mowers without self propulsion and electric models were left out.
Gas Powered Self Propelled Lawn Mower Reviews
1. PowerSmart 21" 170cc Self Propelled Gas Mower: Best Overall
- 170cc OHV four stroke engine with auto choke and recoil start
- 21 inch steel deck
- 3 in 1: mulching, side discharge or rear bagging
- Rear wheel drive self propulsion
- 6 position height adjustment from 1.5 to 3.9 inches with dual lever control
- Foldable handle for storage
Why We Picked It
This PowerSmart gives you the core of a good gas self propelled mower for about the price of a basic push model. The 170cc OHV engine has enough power to cut through thick or wet grass, and the auto choke makes cold starts simpler: you just pull the recoil starter. Rear wheel drive is the right choice for hills and uneven ground, because weight shifts to the back wheels as you climb, which keeps them gripping.
The steel deck adds durability, and the 3 in 1 design means you can mulch clippings back into the lawn in summer, bag them in spring, or side discharge when the grass gets long. Six height positions from 1.5 to 3.9 inches cover everything from a short summer cut to a taller, drought friendly setting. When the season ends, the handle folds for compact storage.
It is also a forgiving first gas mower. The controls are simple, there is no transmission to adjust, and parts like blades, filters and spark plugs are standard and easy to find. If you are moving up from a push mower or a small corded electric model, the difference in effort on a sloped lawn is immediately noticeable.
Pros
- Gas power and self propulsion for a low price
- Rear wheel drive helps on hills
- Handles tall and wet grass
- Three cutting modes and a steel deck
Cons
- Recoil start and regular engine upkeep
- Louder than electric mowers
- Single speed drive with no pace control
Who Should Buy It
Choose the PowerSmart 21 inch if you want an affordable gas self propelled mower for a medium to large lawn, especially one with gentle slopes. It suits homeowners who are comfortable with basic engine care and want to stop pushing a mower uphill. Expect to pay around $300.
2. YARDMAX 22" 201cc Select PACE 6 Speed Self Propelled Gas Mower: Best Premium Pick
- 201cc gas engine with an automatic choke (no priming)
- 22 inch deck with 3 in 1 mulch, bag and side discharge
- Select PACE 6 speed CVT front wheel drive
- High rear wheels with rubber tires and an aggressive spiked tread
- Single lever deck height adjustment
- Deck cleanout port
Why We Picked It
The YARDMAX Select PACE stands out for its continuously variable transmission. Instead of one fixed speed, you choose from six settings on a lever so the mower matches your walking pace, whether you stroll slowly through thick spring grass or move quickly on a summer trim. The 201cc engine is the largest in our top three, which helps in tall, dense or weedy grass that bogs down smaller engines.
The 22 inch deck cuts a wider strip on each pass, saving time on larger yards. Spiked rubber tires add traction, and the high rear wheels roll smoothly over bumps. Practical touches round it out: the automatic choke means no priming, the single lever changes cutting height for the whole deck at once, and the cleanout port lets you rinse grass buildup from under the deck with a hose.
Pros
- Big engine for thick grass
- Adjustable pace with the 6 speed CVT
- Wide cut saves time
- Single lever height change and deck wash port
Cons
- Front wheel drive loses grip uphill with a full bag
- Heavy and loud
- Bigger to store than a 21 inch model
Who Should Buy It
Buy the YARDMAX Select PACE if you have a large, mostly flat yard with thick grass and want a mower that moves at your pace. Front wheel drive also makes it easy to tip up and turn around trees and beds. Expect to pay around $360.
3. PowerSmart 22" 170cc High Wheel Self Propelled Gas Mower: Runner Up
- 170cc OHV engine
- 22 inch cutting width
- 2 in 1 design
- Rear wheel drive self propulsion
- High rear wheels
Why We Picked It
This PowerSmart takes the reliable 170cc OHV engine and pairs it with a wider 22 inch deck and large high rear wheels. That combination is ideal for rough or uneven lawns, where small wheels catch on bumps and ruts. Rear wheel drive adds traction going uphill, so it is a sensible budget choice for sloped or lumpy yards.
The 22 inch width cuts more grass per pass than standard 21 inch mowers, which adds up on larger properties. Its 2 in 1 design offers two cutting modes rather than the three found on 3 in 1 mowers, so it is best for owners who mostly bag or discharge clippings rather than mulch.
Pros
- Wide 22 inch cut
- High wheels roll over bumps
- Rear wheel drive for slopes
- Very affordable
Cons
- No mulching mode
- Basic features with no pace control
- Smaller review base than the 21 inch model
Who Should Buy It
Pick the PowerSmart 22 inch High Wheel if your yard is bumpy, sloped or large and you want a wider cut without paying premium prices. It is a solid workhorse for owners who do not need mulching. Expect to pay around $340.
The comparison table includes several other gas self propelled mowers worth considering. SENIX offers 201cc models with variable speed and rear wheel drive, the YARDMAX 24 inch adds electric start and an even wider cut for big lawns, and the CRAFTSMAN 21 inch 140cc is a familiar name with a mulching kit and bag included.
Why Choose Gas Power
Battery mowers have improved a lot, but gas still has clear advantages for certain yards.
Power and runtime advantages
Gas engines deliver strong, steady torque in tall, wet or thick grass, and they never slow down as a battery drains. Runtime is limited only by the fuel tank, and a quick refill gets you back to mowing in seconds. For lawns of half an acre or more, that unlimited runtime is a big advantage.
Maintenance and fuel
Gas mowers need oil changes, air filter cleaning, spark plug replacement and fresh fuel. Use fuel stabilizer if gas will sit for more than a month, and drain or stabilize the tank before winter. Most owners can do this basic upkeep in under an hour a season.
Noise and emissions rules
Gas mowers are louder than battery models, so hearing protection is a good idea. Some areas, including parts of California, restrict the sale of new small gas engines, so check local rules before you buy.
Cost over time is another point in favor of gas for larger yards. A comparable battery self propelled mower with a big enough battery for half an acre or more often costs well over $500, and replacement batteries are expensive. A gas mower costs less up front, and its running costs are mostly a few gallons of fuel, a quart of oil and a spark plug each season. For small lawns, though, the quiet and low upkeep of battery power can be worth the higher price.
How to Choose the Best Gas Powered Self Propelled Lawn Mower
These factors decide which mower fits your lawn and budget.
Cutting Width and Deck Material
Most gas walk behind mowers cut 21 or 22 inches, while some reach 24 inches or more. Wider decks save time on big lawns but are heavier and harder to maneuver around beds. Steel decks are common and durable; keep them clean and dry to prevent rust.
Power Source: Battery, Corded or Gas
Gas suits large lawns, thick grass and hilly ground. Battery mowers are quieter and need less maintenance but cost more for similar runtime. Corded mowers are cheap and light but limited by the cord, so they suit only small yards. Our guide to the best self propelled lawn mower compares all three.
Self Propelled vs Push
Self propelled mowers drive the wheels for you. Rear wheel drive is best for hills, front wheel drive is easier to turn on flat lawns, and all wheel drive handles the steepest, roughest ground. Push mowers are cheaper and lighter but tiring on large or sloped yards.
Engine Size and Starting System
Engines from about 140cc to 170cc handle typical suburban lawns, while 190cc to 201cc engines have extra torque for tall and dense grass. Auto choke systems remove the need to prime, and electric start, found on some higher end models, makes starting effortless.
Height Adjustment Range
Look for at least six height positions, ideally from about 1.5 to 4 inches. Single or dual lever systems are faster than adjusting each wheel. Taller cuts in summer help grass resist drought and weeds.
As a rule, never remove more than one third of the grass blade in a single mow. If the lawn has grown long after rain or a vacation, raise the deck to its highest setting for the first pass, then lower it a notch for a second pass a few days later. A strong engine helps here, but the right height protects the lawn.
Mulch, Bag and Side Discharge
3 in 1 mowers mulch, bag and side discharge. Mulching returns nutrients to the soil, bagging gives a tidy finish and collects leaves, and side discharge handles tall grass. 2 in 1 models usually drop mulching.
Weight, Folding and Storage
Gas self propelled mowers are heavy, so check that you can move them in and out of storage. Folding handles save space in sheds and garages, and high rear wheels make the mower easier to roll when the engine is off.

FAQs About Gas Powered Self Propelled Lawn Mowers
How long does a self propelled lawn mower last?
A well maintained gas self propelled mower typically lasts 8 to 10 years, and many run longer. The engine usually outlasts the drive system, so belts and drive cables may need replacing along the way. Changing the oil each season, keeping the blade sharp and storing the mower dry with stabilized fuel all extend its life.
Is a self propelled lawn mower worth the money?
For lawns larger than about a quarter acre or any yard with slopes, yes. A self propelled mower cuts the physical effort of mowing dramatically and usually costs only $50 to $150 more than a comparable push mower. The difference is most noticeable when you bag clippings, since a full bag adds a lot of weight.
How much should I spend on a self propelled lawn mower?
Good gas self propelled mowers start around $300. Models with bigger engines, variable speed or electric start usually cost $350 to $650. Premium and commercial grade machines can exceed $800. Compare prices and retailers in our guide on where to buy a lawn mower.
How do I maintain a self propelled lawn mower?
Check the oil before each use and change it every season. Clean or replace the air filter, swap the spark plug yearly, and sharpen the blade once or twice a season. Clean grass from under the deck, check the drive belt for wear, and use fresh fuel with stabilizer for storage.
