More Details on Our Top Picks
PowerSmart 18-inch 144cc Gas Lawn Mower with Side-Discharge
This model stands out for its lightweight design and reliable engine, making it ideal for smaller lawns or yards with tight spaces. Compared with the Amerisun 21-inch mower, it offers easier handling but sacrifices some cutting width, which could mean longer mowing times for larger areas. Its steel deck ensures durability, yet the limited five height adjustments and absence of mulching or bagging features might frustrate homeowners seeking more versatility. Noise levels could also be higher due to the gas engine, which is typical of this size but worth considering in noise-sensitive environments.
Pros:- Lightweight and easy to maneuver
- Reliable 144cc engine with easy start technology
- Durable steel deck for long-lasting use
Cons:- Limited to 5 cutting height options
- No mulching or bagging options
- Potentially noisy due to gas engine
Best for: Small yard owners who prioritize ease of maneuverability and quick setup
Not ideal for: Large lawns that require longer mowing sessions or advanced features like mulching or bagging
- Engine:144cc 4-stroke OHV
- Blade Size:18 inches
- Cutting Height:1.5 to 3.9 inches
- Wheels:8-inch rear, 7-inch front
- Deck Material:Steel
Our verdict“This mower is best suited for homeowners with small to medium yards who need a simple, reliable machine that’s easy to handle.”
Amerisun 21-inch Gas Lawn Mower, 144cc 4-Stroke, 2-in-1 Push Mower
The Amerisun 21-inch mower makes a strong case for those managing small to medium-sized yards needing flexible options. Its wider deck offers faster coverage than the PowerSmart 18-inch, and the inclusion of mulching and side discharge features provides more versatility than the smaller model. However, it relies on recoil start only, unlike the PowerSmart with electric start, which could be less convenient after a long day of yard work. Its lighter weight at 63 lbs makes it easy to fold and store, but it’s not designed for very large lawns, where a self-propelled model might be more efficient.
Pros:- Powerful 144cc engine suitable for medium yards
- Adjustable cutting heights and mulching options
- Lightweight and foldable for storage
Cons:- Recoil start may be less convenient
- Limited to small and medium yard sizes
- No electric start option
Best for: Homeowners with small to medium yards who value multi-functionality and portability
Not ideal for: Large, hilly landscapes or users who prefer electric start for convenience
- Engine:144cc 4-stroke OHV
- Cutting Width:21 inches
- Weight:63 lbs
- Cutting Height Adjustment:1.5 to 3.9 inches
- Discharge Options:Mulching and side discharge
Our verdict“This mower is a practical choice for users who want a flexible, easy-to-store machine for regular yard maintenance.”
YARDMAX 22 in. 201cc Select PACE 6 Speed CVT High Wheel FWD 3-in-1 Gas Walk Behind Self Propelled Lawn Mower, Black (YG2860)
The YARDMAX 22-inch model introduces a CVT transmission that offers precise control, making it suitable for varied terrain. Its spiked tires deliver superior traction compared to the other options, especially on uneven ground. The automatic choke simplifies starting, and the quick height adjustment streamlines mowing sessions. However, its higher wheel design and heavier weight could be challenging for users seeking a lighter, more agile mower. Its modern features come at a slightly higher price point, but the ability to tailor speed adds value for more demanding lawns.
Pros:- Smooth, adjustable CVT transmission for precise control
- Excellent traction due to aggressive spiked tires
- Easy start with automatic choke
Cons:- Heavier and less maneuverable for small yards
- Limited color options
- Higher price compared to basic models
Best for: Homeowners with varied terrain or those who prefer customizable speed settings
Not ideal for: Users seeking a lightweight, simple mower without advanced features
- Cutting Width:22 inches
- Engine Displacement:201cc
- Transmission:6-speed CVT
- Tire Type:Rubber with spiked tread
- Features:Deck cleanout port, single-lever height adjustment
Our verdict“Ideal for users needing adaptable speed and traction on challenging terrain, though less suitable for small, flat lawns.”
BILT HARD 21-Inch Self-Propelled Gas Lawn Mower with 201cc Engine, 3-in-1 Mulching, Bagging, Side Discharge, and Adjustable Heights
The BILT HARD 21-inch mower offers a strong combination of power and versatility, with a 201cc engine that handles larger or thicker grass easily. Its self-propelled rear-wheel drive reduces manual effort, especially on uneven terrain, making it a good choice for those seeking comfort. The 3-in-1 feature set—mulching, bagging, side discharge—outperforms the simpler PowerSmart model by providing more mowing options. Its adjustable height and no-choke start simplify operation, but the single-speed drive limits adaptability on different terrains, and maintenance is still required as with all gas models. Its steel deck and multiple functions justify its higher price point.
Pros:- Powerful 201cc engine for demanding lawns
- 3-in-1 mowing options (mulching, bagging, side discharge)
- No-choke, easy start system
Cons:- Single-speed drive may not suit all terrains
- More maintenance typical of gas-powered mowers
- Heavier than smaller models
Best for: Homeowners needing a powerful, versatile mower for varied yard conditions
Not ideal for: Users with very flat or small yards who prefer a lighter or simpler machine
- Engine:201cc 4-stroke OHV
- Cutting Width:21 inches
- Cutting Heights:1.2 to 3.75 inches
- Drive:Rear-wheel, single-speed self-propelled
- Discharge Options:Mulching, side discharge, rear bagging
Our verdict“This mower is a strong choice for users who need power and versatility in their yard equipment, especially on uneven ground.”
PowerSmart 21-Inch 144cc Gas Push Lawn Mower + 16-Inch String Trimmer + 40V Cordless Leaf Blower (150 MPH / 450 CFM)
This kit combines a capable 21-inch gas mower with supplementary tools, making it ideal for homeowners who want a comprehensive yard care setup. The gas mower, with a 144cc engine, offers the same basic power as the PowerSmart model but adds the benefit of a full toolset, including a string trimmer and cordless blower. The blower’s 40V battery system provides longer runtime than standalone battery tools, and the inclusion of multiple tools saves money compared to buying separately. However, the gas mower requires regular maintenance, and the combined bulk of the tools might be cumbersome for storage or transport. The blower’s runtime depends on the batteries’ charge, which may be limiting for larger yards.
Pros:- Complete yard maintenance kit for medium yards
- Powerful blower with long runtime using two batteries
- Versatile 3-in-1 mower with mulching, bagging, side discharge
Cons:- Gas mower requires regular maintenance
- Tools may be bulky for storage
- Battery blower’s runtime may be limited on a single charge
Best for: Homeowners seeking an all-in-one yard care solution for medium-sized yards
Not ideal for: Those with very small yards or who prefer purely electric tools to reduce noise and maintenance
- Lawn Mower Size:21 inches
- Lawn Mower Engine:144cc 4-cycle
- String Trimmer Length:16 inches
- String Trimmer Engine:25.4cc 2-cycle
- Leaf Blower Voltage:40V (2x 20V batteries)
- Leaf Blower Airflow:450 CFM
- Leaf Blower Speed:150 MPH
Our verdict“Perfect for users wanting a comprehensive, multi-tool yard setup, though at the expense of added complexity and maintenance.”
PowerSmart 21-Inch Self-Propelled Gas Lawn Mower with 170cc OHV Engine
This model stands out for its combination of a powerful 170cc engine and a sizable 21-inch deck, making it suitable for mid-sized yards that require efficient coverage. Compared with the PowerSmart 22-inch models, it offers slightly lighter weight and easier handling, though it sacrifices some cutting width. Its 3-in-1 system provides flexibility for bagging, mulching, or discharging, which is ideal for varied lawn conditions. The rear-wheel drive enhances maneuverability on slopes, but the heavier weight may challenge users with limited strength. It’s a solid choice for homeowners who want reliable performance without the premium price of higher-end models. However, the absence of an electric start means more effort to get going. Overall, this mower suits those seeking a balanced mix of power and versatility for medium yards.Pros:- Powerful 170cc engine for reliable, strong performance
- Wide 21-inch deck reduces mowing time
- Versatile 3-in-1 system for different lawn needs
- Rear-wheel drive improves slope handling
Cons:- Heavier than some comparable models, may be difficult for some users
- No electric start, requiring manual recoil pull
Best for: Homeowners with medium-sized, varied terrain lawns who prioritize power and versatility.
Not ideal for: Elderly users or those with limited strength, due to its weight and lack of electric start.
- Engine:170cc OHV
- Cutting Width:21 inches
- Bag Capacity:1.4 bushels
- Cutting Heights:1.5 to 3.9 inches
- Wheels:10-inch rear wheels

Our verdict“This mower offers a great balance of power and features for medium yards, especially if you want robust performance at a reasonable price.”
PowerSmart EasyCut 18-Inch Gas Lawn Mower, 144cc 4-Cycle Engine, Walk-Behind Push Lawn Mower, Side Discharge, 5-Position Height Adjustment
This smaller, 18-inch mower is a straightforward choice for beginners or those with small, manageable lawns. Its 144cc engine offers reliable power, similar to the PowerSmart 18-inch model, but with the added benefit of a durable steel deck that withstands regular use. The five adjustable height settings provide flexibility for different grass conditions, and the lightweight design makes it easier to maneuver around tight spaces. Unlike larger models like the PowerSmart 22-inch, this mower prioritizes ease of use over coverage, making it ideal for small yards or new users. Its automatic choke and primer simplify starting, reducing frustration for novices. However, its limited size and weight make it unsuitable for larger properties or thick grass. This pick is best for first-time homeowners or those with small lawns seeking a simple, dependable mower.Pros:- Easy to start with auto choke and primer
- Durable steel deck for longevity
- Multiple height adjustment options
- Lightweight and maneuverable
Cons:- Limited to small yard sizes
- May be heavy for some users despite being smaller
Best for: Homeowners with small, flat lawns who prefer a lightweight, easy-to-start mower.
Not ideal for: Users with large or hilly yards, as its small size and limited power may struggle with thick grass or slopes.
- Engine:144cc 4-stroke OHV
- Cutting Width:18 inches
- Deck Material:Steel
- Height Adjustment:5 positions (1.5″ to 3.9″)
- Wheels:8″ rear, 7″ front
Our verdict“This mower is perfect for beginners or homeowners with small, flat lawns who want simple operation and reliable performance.”
PowerSmart 22-Inch Self Propelled Gas Lawn Mower, 170cc 4-Cycle OHV Engine, 3-in-1 Mulch/Bag/Rear Discharge, 6 Cutting Heights
This 22-inch mower with a 170cc engine is designed for homeowners tackling large or dense lawns. Its larger deck covers more ground quickly, making it a time-saver compared to smaller models like the PowerSmart EasyCut. The 3-in-1 system offers flexibility for different grass conditions, and the six adjustable cutting heights help fine-tune your cut. The powerful engine can handle thick, overgrown grass better than smaller engines, though it’s also heavier and less nimble for tight spaces. The foldable handle simplifies storage, but the lack of electric start means more effort to get it running, especially in colder weather. This mower is best suited to those with substantial yards or thick grass who prioritize power and efficiency over ease of starting.Pros:- Large 22-inch deck reduces mowing time
- Powerful 170cc engine handles thick grass
- Versatile 3-in-1 system for various lawn conditions
- Folding handle for convenient storage
Cons:- Heavier and more challenging to maneuver in tight spaces
- No electric start, requiring manual pull
Best for: Homeowners with large or overgrown yards needing a robust, versatile mower.

PowerSmart 22-Inch 170cc Self Propelled Gas Lawn Mower
This 22-inch mower with a 170cc engine and self-propelled rear-wheel drive is a practical choice for uneven terrain or hilly yards. Its 22-inch deck accelerates coverage, while the self-propel feature reduces fatigue when mowing slopes, outperforming push-only models like the PowerSmart EasyCut. The adjustable height settings and versatile cutting options make it adaptable to different grass lengths and conditions. However, its weight can still challenge users with limited strength, and it lacks an electric start, which could slow down routine use. Compared to smaller or less powerful models, this mower excels in handling challenging terrain but requires a bit more effort to operate. It appeals to homeowners with hilly or sloped landscapes who want a dependable, powerful mower.Pros:- Self-propelled rear-wheel drive for slopes
- Powerful 170cc engine for difficult terrain
- Versatile cutting options and adjustable heights

This 20-inch mower with a 144cc engine offers a balanced mix of affordability and functionality, making it suitable for budget-conscious homeowners with small to medium lawns. Its 8-position adjustable height gives greater control over the cut, and the durable double ball-bearing wheels ensure smooth maneuverability. Compared with larger, more powerful models like the PowerSmart 22-inch, it’s less suited for thick or overgrown grass but excels in ease of handling and storage. The auto choke feature simplifies starting, which is a plus for casual users. However, it’s relatively heavy for its size and lacks detailed handle adjustability, which could impact comfort. This mower makes the most sense for users who want reliable basic mowing without extra bells and whistles.Pros:- Auto choke engine for easy starting

How We Picked
I evaluated these gas lawn mowers based on key factors that matter most to homeowners: cutting performance, ease of operation, build quality, maintenance requirements, and overall value. I compared engine sizes, weight, maneuverability, and additional features like mulching and self-propulsion. The ranking emphasizes models that balance power with user-friendly features, prioritizing those suited for different yard sizes and user experience levels. Products with a proven track record of reliability and positive reviews also influenced their placement, ensuring that the top picks are both dependable and versatile.Factors to Consider When Choosing Gas Lawn Mowers
Choosing the right gas lawn mower involves weighing several important factors. While engine power and cutting width are obvious considerations, other elements like maneuverability, maintenance, and additional features can significantly impact your overall satisfaction. Understanding these broader considerations helps prevent common mistakes, such as overpaying for unnecessary features or selecting a mower that’s too powerful for your yard. A well-chosen mower should fit your yard size, terrain, and personal comfort with maintenance tasks.Engine Power and Size
Engine size directly influences cutting power and the ability to handle thick or tall grass. Larger engines, typically 170cc or more, excel in larger yards or challenging conditions but add weight and fuel consumption. Smaller engines, around 140cc, are lighter, easier to maneuver, and ideal for small to medium lawns. Avoid selecting a mower with an engine that’s too large for your yard, as it can become cumbersome and unnecessary, increasing costs without added benefit.
Maneuverability and Self-Propulsion
Self-propelled models make mowing less tiring, especially for larger or hilly lawns. They typically cost more but save time and effort. Consider the terrain: flat yards might do well with push models, while sloped or expansive lawns benefit from self-propulsion. Be aware that self-propelled mowers are heavier and often more complex to repair, so balance convenience with long-term maintenance needs.
Cutting Width and Height Adjustments
Wider cutting decks reduce mowing time for large areas but can be harder to maneuver around obstacles. Smaller decks are more agile and better suited for tight spaces or irregularly shaped lawns. Look for models with adjustable height settings—preferably multiple positions—to tailor cutting height according to grass type and season. This flexibility can improve lawn health and aesthetics.
Features and Versatility
Additional features like mulching, bagging, and side discharge add versatility. Mulching can improve lawn health by recycling clippings, while bagging simplifies cleanup. However, more features often mean increased complexity and potential for breakdowns. Consider your specific needs: if you prefer quick cleanup, prioritize models with reliable bagging options; for eco-conscious mowing, mulching capabilities matter more.
Maintenance and Durability
Gas mowers require regular maintenance—changing oil, replacing spark plugs, and cleaning filters. Models with simple access panels and durable components reduce downtime and repair costs. Investing in a well-built mower with high-quality materials often pays off over time, especially if you have a large or demanding yard. Don’t overlook user reviews about long-term durability when making your decision.
Frequently Asked Questions
How often should I change the oil in my gas mower?
Most gas mowers benefit from an oil change after every 25-50 hours of use, typically once per mowing season. Regular oil changes help maintain engine health and efficiency, especially if you use the mower frequently. Always refer to the manufacturer’s recommendations for the specific model, as oil change intervals can vary based on engine size and usage conditions. Using the right oil type and level also prevents engine damage and prolongs the mower’s lifespan.
Is a self-propelled mower worth the extra cost?
Self-propelled mowers are generally worth the extra expense if you have a large or hilly yard, as they reduce physical effort and mowing time. They make handling thick or tall grass easier and help prevent fatigue during extended use. However, they are heavier, often more expensive, and require more maintenance. If your lawn is small or flat, a push mower might suffice, saving you money and reducing complexity.
What should I look for in terms of durability?
Durability depends on the quality of materials used—such as a sturdy steel deck versus plastic—and the engine’s robustness. Look for models with reinforced components, corrosion-resistant parts, and engines from reputable brands. User reviews can offer insight into long-term performance, especially regarding engine longevity and ease of repairs. Investing in a well-made mower can prevent frequent breakdowns and extend the lifespan of your equipment.
Can I use the same gas in my mower as I use in my car?
While you can technically use the same gas, most gas mowers perform best with fresh, clean fuel. Many recommend using unleaded gasoline with a stabilizer if storing for more than a month, to prevent fuel degradation. Avoid ethanol-blended fuels if possible, as they can cause problems in small engines over time. Properly mixing or choosing the right fuel can help maintain engine performance and reduce maintenance needs.
How important is engine size relative to lawn size?
Engine size should match the size and conditions of your yard. Larger engines provide more power for thick or tall grass and large lawns, making mowing easier and faster. Smaller engines are sufficient for small, flat lawns and require less fuel, making them lighter and more maneuverable. Selecting an engine that’s too large for your yard can lead to unnecessary weight and cost, while an underpowered engine may struggle with thicker grass or larger areas.
Conclusion
For most homeowners with medium to large lawns, the PowerSmart 22-Inch Self-Propelled Gas Lawn Mower offers the best overall balance of power and ease of use. Budget-conscious buyers will find the PowerSmart 18-inch 144cc Gas Lawn Mower a dependable choice. Those seeking a premium experience might consider models with higher engine capacity and additional features, like the YARDMAX 22 in. 201cc. Beginners or those with small yards should lean toward lighter, simpler push mowers, while large yard owners with challenging terrain may prefer self-propelled, high-horsepower options. Tailor your choice based on yard size, terrain, and your comfort level with maintenance for the best results.
