Key Takeaways

  • Battery-powered models like the Greenworks 60V offer cleaner operation with less noise but may have limited runtime compared to gas options.
  • Gas mowers generally provide more power for larger or tougher lawns but require more maintenance and are heavier to maneuver.
  • Multi-function cutting systems (mulching, bagging, discharge) add versatility but often increase the price and complexity of operation.
  • Models with adjustable speed and height settings give better control, especially on uneven terrain.
  • The best mower depends heavily on your lawn size, terrain, and preference for power source—there’s no one-size-fits-all.

More Details on Our Top Picks

  1. Greenworks 60V 21 in Self-Propelled Lawn Mower, (2) 4.0 Ah Battery Kit

    Greenworks 60V 21 in Self-Propelled Lawn Mower, (2) 4.0 Ah Battery Kit

    Best Overall for Eco-Friendly Performance

    View on Amazon

    This Greenworks model stands out for combining cordless convenience with impressive power, rivaling gas options like the SENIX 22” mower. Its brushless motor delivers a gas-like performance while operating much more quietly, making it ideal for early mornings. The adjustable rear-wheel drive simplifies handling on uneven terrain, and the 4-in-1 options offer flexibility for different lawn conditions. Compared to the Greenworks 40V model, the 60V system provides longer runtime and more power, but it comes with a higher price tag and heavier weight, which may challenge some users. Its water-resistant build and extended warranty add value, yet the battery runtime could vary with terrain. This pick makes the most sense for eco-conscious homeowners seeking a high-performance, low-noise mower with versatile mowing features.

    Pros:
    • Powerful brushless motor offers performance comparable to gas mowers
    • Quiet operation reduces noise disturbances
    • Adjustable self-propelled rear-wheel drive for ease of use
    • Versatile 4-in-1 cutting options (mulch, bag, side discharge)
    Cons:
    • Battery runtime may be limited on hilly or dense grass
    • Heavier weight could be challenging for some users
    • Higher purchase price compared to gas or corded models

    Best for: Homeowners with medium-sized yards prioritizing quiet, eco-friendly operation and adjustable self-propelled drive.

    Not ideal for: Users with very large lawns or those on a tight budget, as the initial cost and weight may be barriers.

    • Battery Voltage:60V
    • Cutting Width:21 inches
    • Battery Capacity:2x 4.0Ah
    • Runtime:60+ minutes
    • Drive System:Self-propelled rear-wheel drive
    • Water Resistance:IPX4-rated
    • Warranty:4 years tool + 4 years battery
    Our verdict
    “This mower is best suited for those seeking a quiet, eco-conscious, and versatile self-propelled mower with substantial power.”
  2. 21-Inch Self-Propelled Gas Lawn Mower with 170cc 4-Cycle Engine

    21-Inch Self-Propelled Gas Lawn Mower with 170cc 4-Cycle Engine

    Best for Power and Thicker Grass

    View on Amazon

    This gas-powered mower excels at tackling thick, overgrown grass, outperforming electric models like the Greenworks 60V in raw engine strength. Its 170cc 4-cycle engine provides ample torque for demanding conditions, and the steel deck ensures durability. Its 3-in-1 system offers versatile mowing options, but the heavier weight and noisier operation make it less suitable for small yards or early morning mowing. Unlike the SENIX 22”, which has a slightly larger deck and more adjustable features, this model is better for users who need maximum power and don’t mind the maintenance of gas engines. It lacks electric start, which could frustrate some, especially those seeking convenience. This model is ideal for homeowners with challenging lawns who prioritize power over quietness or ease of use.

    Pros:
    • Powerful 170cc engine handles thick grass effortlessly
    • Versatile 3-in-1 cutting system for different lawn needs
    • Large 21-inch cut width reduces mowing time
    Cons:
    • Heavier and potentially more tiring to operate
    • No electric start; manual pull required
    • Noisier operation compared to electric models

    Best for: Users with thick, overgrown lawns needing a robust mower that handles tough conditions without hesitation.

    Not ideal for: Those with small yards or who prefer quiet, low-maintenance electric models due to noise or weight concerns.

    • Engine:170cc 4-Cycle OHV
    • Cutting Width:21 inches
    • Grass Bag Capacity:1.9 bushels
    • Cutting Height Adjustment:7 positions from 1 to 3 inches
    • Deck Material:Steel
    • Warranty:1 year
    Our verdict
    “This gas mower makes the most sense for those needing maximum power and durability for challenging lawns, accepting more noise and weight.</p>”
  3. SENIX 22” Self Propelled Gas Lawn Mower, 170cc 4-Cycle Engine, 3-in-1 (Bagging/Mulching/Side Discharge), Adjustable Height

    SENIX 22'' Self Propelled Gas Lawn Mower, 170cc 4-Cycle Engine, 3-in-1 (Bagging/Mulching/Side Discharge), Adjustable Height

    Best for Small to Medium Yards with Versatile Features

    View on Amazon

    The SENIX 22” mower offers a slightly wider cut and a rugged steel deck, making it ideal for homeowners with small to medium-sized lawns. Its 170cc engine delivers reliable power, comparable to the PowerSmart 22”, but with a focus on durability and ease of use. The 3-in-1 system adds flexibility, and the adjustable height settings help tailor the cut. However, it lacks electric start, and its weight isn’t specified, which could impact maneuverability. Compared with the PowerSmart 22”, it provides more robust build quality and storage options, but at a similar price point. It’s best for users who want a dependable, versatile gas mower that can handle varied lawn conditions without fussing over complex features. Not suitable for those seeking electric or battery-powered convenience, especially for large lawns.

    Pros:
    • Versatile 3-in-1 system for mulching, bagging, and side discharge
    • Adjustable height for precise lawn control
    • Reliable 170cc engine for consistent power
    • Foldable handle for compact storage
    Cons:
    • Lack of electric start may be inconvenient
    • Weight and maneuverability not specified, potentially challenging for some users
    • Limited to small to medium lawns

    Best for: Homeowners with small to medium-sized yards needing reliable, versatile mowing with adjustable features.

    Not ideal for: Large lawn owners or those wanting electric start or lighter weight for easy maneuverability.

    • Engine:170cc 4-cycle OHV
    • Cutting Width:22 inches
    • Bag Capacity:19 gallons
    • Cutting Height Adjustment:6 positions, 1.25″ to 4″
    • Wheels:8″ front, 11″ rear
    • Warranty:2 years
    Our verdict
    “This mower is well-suited for homeowners who need a durable and versatile gas mower for moderate yard sizes, willing to handle manual start and moderate weight.</p>”
  4. 21-Inch Self Propelled Gas Lawn Mower with 170cc 4-Stroke Engine, 4-in-1 Cutting System, and Foldable Handle

    21-Inch Self Propelled Gas Lawn Mower with 170cc 4-Stroke Engine, 4-in-1 Cutting System, and Foldable Handle

    Best for Compact Storage and Heavy Duty Power

    View on Amazon

    This 21-inch gas mower combines power with convenience, thanks to its foldable handle and 4-in-1 system, outperforming smaller push mowers like the PowerSmart 21″ in features. Its 170cc engine offers strong performance, and the versatile cutting options suit a range of lawn conditions. The foldable handle makes storage straightforward, making it an excellent choice for users with limited space. However, weight might be an issue for some, and assembly can be time-consuming. It’s less suitable for users with very large lawns due to fuel capacity limits, which restrict continuous mowing time. Compared to electric models like the Greenworks 40V, it requires more maintenance and noise management but provides more power and independence from cords or batteries. This mower is perfect for homeowners who want a robust, space-efficient gas mower for moderate yard work.

    Pros:
    • Powerful 170cc engine handles thick grass
    • 4-in-1 system offers versatile cutting options
    • Foldable handle for compact storage
    Cons:
    • Heavier weight may be challenging for some users
    • Requires assembly before use
    • Limited continuous operation due to fuel capacity

    Best for: Homeowners needing a powerful, space-saving gas mower capable of handling diverse lawn conditions with ease.

    Not ideal for: Large lawn owners or those seeking electric or cordless convenience for frequent, extended mowing sessions.

    • Engine:170cc 4-stroke OHV
    • Cutting Width:21 inches
    • Cutting Heights:7 positions from 1 to 3 inches
    • Grass Bag Capacity:65L / 17.5 gal
    • Wheels:8″ front, 10″ rear
    • Folded Dimensions:36″L x 28″W x 21″H
    Our verdict
    “This mower is ideal for users who need a durable, powerful machine with space-saving features for moderate-sized lawns, accepting some weight and maintenance requirements.</p>”
  5. Greenworks 40V 21-inch Self-Propelled Lawn Mower with 5.0 Ah Battery and Charger

    Greenworks 40V 21-inch Self-Propelled Lawn Mower with 5.0 Ah Battery and Charger

    Best for Cordless Convenience and Extended Runtime

    View on Amazon

    This Greenworks 40V model offers a compelling mix of power and portability, standing out from corded counterparts like the PowerSmart models. Its brushless motor delivers quiet, efficient operation, with the 5.0Ah battery providing longer runtime—ideal for homeowners with medium-sized lawns. The self-propelled rear-wheel drive with adjustable speed makes mowing effortless, even on uneven terrain. The 4-in-1 system adds versatility, and including a battery, charger, and grass bag makes it a complete package. Compared to the 60V model, it offers slightly less power but at a more affordable price point and lighter weight, which benefits maneuverability. Its biggest limitation is the battery life, which could be restrictive on larger properties. This model suits environmentally conscious users who want cordless convenience and reliable power for moderate yards.

    Pros:
    • Powerful brushless motor for efficiency and quiet operation
    • Long-lasting 5.0Ah battery for extended mowing sessions
    • Self-propelled with adjustable speed for ease of use
    • Includes battery, charger, and grass bag for convenience
    Cons:
    • Battery life may be limiting for larger lawns
    • Heavier than corded models, affecting maneuverability
    • Higher price compared to basic corded models

    Best for: Homeowners with medium-sized lawns seeking a quiet, efficient, and portable mower with a complete ecosystem.

    Not ideal for: Lawn owners with very large areas or those who need maximum runtime without charging interruptions.

    • Battery Capacity:5.0 Ah
    • Deck Size:21 inches
    • Motor Type:Brushless
    • Drive:Self-propelled rear-wheel drive
    • Lighting:LED headlights
    • Warranty:3 years tool + 3 years battery
    Our verdict
    “This mower is best suited for users who value cordless flexibility, longer runtime, and a complete package for medium-sized lawns, accepting some weight and price considerations.</p>”
  6. Greenworks 80V 21-inch Self-Propelled Lawn Mower with 4.0 Ah Battery and Charger

    Greenworks 80V 21-inch Self-Propelled Lawn Mower with 4.0 Ah Battery and Charger

    Best Overall Electric Self-Propelled Mower

    View on Amazon

    This Greenworks model stands out for its combination of power and eco-friendliness, thanks to an 80V battery and a brushless motor that delivers strong torque while maintaining quiet operation. Its self-propelled rear-wheel drive with variable speed makes mowing on different terrains more manageable, especially compared to gas models like the PowerSmart 170cc. The versatile 4-in-1 system enhances functionality, handling mulching, bagging, side discharge, and leaf pickup. However, the battery life can be inconsistent depending on grass density and operator technique, and the mower’s weight might challenge users with limited strength. Compared to the PowerSmart gas options, it offers a cleaner, quieter experience, but at the expense of runtime per charge. This pick is ideal for eco-conscious homeowners with smaller to medium lawns who prioritize quiet operation and ease of use.

    Pros:
    • Powerful 80V battery for efficient mowing
    • Self-propelled with variable speed for easy maneuverability
    • Quiet operation compared to gas mowers
    • Versatile 4-in-1 system for multiple mowing options
    Cons:
    • Battery life may be limited on dense grass or extended use
    • Heavy for some users when pushing manually

    Best for: Homeowners with medium-sized lawns seeking a quiet, low-maintenance electric mower with versatile functions

    Not ideal for: Large estates or heavy-duty users who need extended runtime or more aggressive power

    • Voltage:80V
    • Deck Size:21 inches
    • Battery Capacity:4.0 Ah
    • Motor Type:Brushless
    • Features:Self-propelled, LED headlights, 4-in-1 system
    • Run Time:Varies with grass density
    Our verdict
    “This model suits those seeking a quiet, versatile, and environmentally friendly mower for manageable lawns.”
  7. YARDMAX 22 in. 201cc Select PACE 6 Speed CVT High Wheel FWD 3-in-1 Gas Walk Behind Self Propelled Lawn Mower

    YARDMAX 22 in. 201cc Select PACE 6 Speed CVT High Wheel FWD 3-in-1 Gas Walk Behind Self Propelled Lawn Mower

    Best for Versatile Gas-Powered Performance

    View on Amazon

    This YARDMAX model stands out for its smooth CVT transmission, which allows seamless speed adjustments that align with walking pace, making it easier to mow large or uneven lawns than the more straightforward power of the Greenworks electric model. Its high rear wheels enhance traction on uneven terrain, and multiple cutting heights offer customized lawn care. However, the advanced features, including the CVT and foldable design, involve a learning curve and add weight, which could challenge less experienced users. Compared to the PowerSmart gas mower with a 170cc engine, the YARDMAX provides more precise speed control but is more complex to operate. This mower suits gardeners who value adaptability and are comfortable managing more advanced features on larger, varied terrains.

    Pros:
    • Smooth CVT transmission for effortless speed control
    • High rear wheels improve traction on uneven ground
    • Multiple cutting height settings for tailored results
    • Deck cleanout port simplifies maintenance
    Cons:
    • Complex features may require some familiarization
    • Heavier weight could be difficult for some users

    Best for: Homeowners with uneven or hilly lawns looking for a flexible, feature-rich gas mower

    Not ideal for: Beginners or users seeking a simple, lightweight lawn mower for small, flat yards

    • Engine:201cc OHV
    • Transmission:CVT
    • Cutting Width:22 inches
    • Number of Speeds:6
    • Wheel Type:High rear wheels
    • Additional Features:Deck cleanout port, foldable design
    Our verdict
    “This mower is best for those who need adaptable performance over challenging terrain and are comfortable with more advanced features.”
  8. PowerSmart 22-Inch 170cc Self-Propelled Gas Lawn Mower with 3-in-1 Mulching, Bagging, and Side Discharge

    PowerSmart 22-Inch 170cc Self-Propelled Gas Lawn Mower with 3-in-1 Mulching, Bagging, and Side Discharge

    Best for Power and Large Yard Coverage

    View on Amazon

    This PowerSmart model offers a robust 170cc engine, making it suitable for thick grass and larger yards, particularly compared to electric options like the Greenworks. Its self-propelled rear-wheel drive reduces physical effort on slopes and uneven terrain, providing a significant advantage for users with hilly lawns. The 3-in-1 cutting system maximizes versatility, and the large 60L grass bag minimizes frequent emptying—ideal for extensive mowing sessions. Yet, the mower’s weight can make prolonged use tiring, and manual start options could be inconvenient for some. Compared with the PowerSmart 21-inch model lacking a 3-in-1 feature, this version offers more flexibility but at the cost of increased weight and complexity. It makes sense for those with demanding lawns who prioritize power and capacity over ease of handling.

    Pros:
    • Powerful 170cc engine for thick grass
    • Self-propelled rear-wheel drive reduces pushing effort
    • Versatile 3-in-1 system with mulching, bagging, and side discharge
    • Large 60L grass bag minimizes emptying
    Cons:
    • Heavy and may be difficult to maneuver for some users
    • Manual start may require more effort

    Best for: Homeowners with large, thick, or hilly lawns needing maximum power and capacity

    Not ideal for: Small yard owners or those preferring lightweight, easy-start electric mowers

    • Engine:170cc 4-stroke OHV
    • Cutting Width:22 inches
    • Cutting Options:Mulching, Bagging, Side Discharge
    • Grass Bag Capacity:60L
    • Drive Type:Rear-Wheel Drive
    • Height Adjustment:1.5 to 3.9 inches
    Our verdict
    “This mower is best suited for those with demanding, large, or hilly lawns who need maximum power and capacity.”
  9. PowerSmart 21-Inch Gas Self-Propelled Lawn Mower with 170cc OHV Engine

    PowerSmart 21-Inch Gas Self-Propelled Lawn Mower with 170cc OHV Engine

    Best for Compact, Efficient Gas Mowing

    View on Amazon

    This PowerSmart model features a 170cc engine that starts reliably and handles thick grass effectively, making it a solid choice for smaller or medium-sized yards. Its 21-inch alloy steel deck offers durability, and the large 10-inch wheels facilitate easy maneuverability across uneven terrain. The multiple cutting height options and foldable handle add to convenience and storage flexibility. Compared to the larger 22-inch model, this mower’s slightly smaller deck makes it lighter and easier to handle, but it might require more passes on bigger lawns. The engine’s ease of start saves time, unlike some manual-start models. It’s particularly suitable for homeowners seeking a durable, efficient gas mower that’s easier to store in tight spaces.

    Pros:
    • Reliable 170cc engine with easy pull start
    • Large 10-inch wheels for smooth maneuverability
    • Durable alloy steel deck for long-term use
    • Foldable handle for compact storage
    Cons:
    • Heavy for prolonged use or extended mowing sessions
    • Blade size (20 inches) may require more passes on large lawns

    Best for: Homeowners with small to medium lawns who want a reliable, easy-to-start gas mower

    Not ideal for: Lawn care professionals or users with very large or hilly yards requiring maximum coverage

    • Engine:170cc OHV
    • Deck Material:Alloy Steel
    • Cutting Width:21 inches
    • Height Adjustment:6 positions (1.5″–3.9″)
    • Wheels:10-inch large wheels
    • Foldable:Yes
    Our verdict
    “This model is perfect for users wanting a durable, reliable gas mower that’s easy to store and operate on small to medium lawns.”
  10. PowerSmart 21-Inch Self Propelled Gas Lawn Mower, 170cc OHV Engine, Rear-Wheel Drive, Steel Deck, 3-in-1 Walk-Behind Mower

    PowerSmart 21-Inch Self Propelled Gas Lawn Mower, 170cc OHV Engine, Rear-Wheel Drive, Steel Deck, 3-in-1 Walk-Behind Mower

    Best Budget-Friendly Versatility

    View on Amazon

    This PowerSmart model offers a practical balance between affordability and features, with a 170cc engine that provides reliable power for typical yard conditions. Its rear-wheel drive and steel deck ensure durability and traction, comparable to the more expensive gas options like the 22-inch YARDMAX. The 3-in-1 system gives flexibility for mulching, side discharge, and bagging, making it suitable for various grass types. Yet, it’s heavier than some electric options, and the absence of advanced features like adjustable speed or high-end comfort elements limits its appeal for extended use. Compared to the more feature-rich models like the 22-inch, this mower emphasizes budget-conscious performance. It suits homeowners seeking a straightforward, dependable gas mower without extra bells and whistles.

    PowerSmart 21-Inch 3-in-1 Gas Self-Propelled Lawn Mower with 170cc OHV Engine

    Best Budget-Friendly Power and Versatility

    View on Amazon

    This model stands out for its combination of a robust 170cc engine and a 21-inch steel deck, making it a reliable choice for homeowners needing efficient coverage without a hefty price tag. Compared to the Greenworks 60V 21 in Self-Propelled Lawn Mower, it offers more power at the expense of weight and noise, which could be a concern for users sensitive to operation noise or those with limited strength. Its 3-in-1 functionality—bagging, mulching, and rear discharge—adds versatility, but the gas engine requires regular maintenance and can be cumbersome for those seeking a low-maintenance, eco-friendly option. The rear-wheel drive enhances maneuverability, especially on uneven terrain, but the mower’s weight and noise level may limit extended use or operation in noise-sensitive environments.

    This pick makes the most sense for budget-conscious homeowners who want a powerful, versatile mower capable of handling various lawn conditions.

    Pros:
    • Powerful 170cc engine ensures reliable, strong performance
    • Wide 21-inch cutting deck speeds up mowing large areas
    • 3-in-1 functionality offers flexibility for different yard needs
    • Adjustable height settings for customized lawn care
    Cons:
    • Heavy design may cause fatigue during extended use
    • Requires regular gas, oil, and maintenance routines
    • Can be noisy during operation, potentially disturbing in noise-sensitive areas

    Best for: Homeowners with medium-sized lawns seeking a reliable, multi-function gas mower who don’t mind weight and noise.

    Not ideal for: Individuals prioritizing quiet operation, low maintenance, or eco-friendly electric mowers due to its noise and maintenance needs.

    • Engine:170cc OHV
    • Cutting Width:21 inches
    • Cutting Heights:1.5 to 3.9 inches
    • Bag Capacity:1.4 bushels
    • Drive:Rear-wheel drive
    • Wheels:10 inches
    • Deck Material:Steel
    Our verdict
    “This mower is best suited for budget-conscious users who need dependable power and versatility and are willing to handle its weight and maintenance.”

Factors to Consider When Choosing Self Propelled Lawn Mower

Choosing the right self propelled lawn mower involves understanding several key factors. Beyond just horsepower or battery capacity, how you plan to use the mower and your terrain significantly influence the best choice. Consider how much lawn you need to mow regularly, whether you prefer gas or electric power, and what features will make mowing easier or more efficient for you. Being aware of these broader considerations helps avoid common pitfalls, like overpaying for unnecessary features or choosing a model that isn’t suited for your landscape.

Power Source and Runtime

Deciding between gas and electric power is fundamental. Gas mowers tend to deliver more consistent power and longer runtime, especially for larger lawns, but they are heavier and noisier. Electric models, particularly battery-powered ones, are quieter, cleaner, and easier to start, but their runtime is limited by battery capacity. Consider your lawn’s size and whether recharge time or fuel storage is a concern—this can make a big difference in overall convenience.

Cutting System and Versatility

Many self propelled mowers come with multiple cutting options, such as mulching, bagging, or side discharge. These features add flexibility and help you manage different grass types or lawn conditions more effectively. However, more complex systems often increase the mower’s cost and maintenance requirements. Think about what’s most important for your lawn—if you prefer simplicity, a basic model might suffice, but for varied needs, a 3-in-1 system offers more value.

Size, Weight, and Maneuverability

Size and weight influence how easy a mower is to handle, especially if you have hilly or tight spaces. Heavier gas models often feel more cumbersome, while lighter electric models improve maneuverability. Adjustable handle height and speed settings can also help tailor the experience. Assess your physical comfort and lawn layout to find a model that balances weight and control without sacrificing power.

Maintenance and Durability

Gas engines require regular oil changes, spark plug replacements, and general upkeep, which can add to long-term costs. Electric models generally demand less maintenance but may need battery replacements over time. Build quality matters—sturdy decks and reliable motors extend the lifespan of your mower. Investing in a durable, well-reviewed model can save money and frustration over the years.

Price and Value

While premium models offer advanced features and higher durability, they come at a higher cost. Mid-range options often strike a good balance between performance and affordability. Avoid paying extra for features you won’t use, but don’t skimp on quality if you have a large or challenging lawn. Think about long-term value—sometimes spending more upfront results in better performance and fewer repairs.

Frequently Asked Questions

How do I know if a battery-powered self propelled mower will last enough for my yard?

Battery runtime depends on both capacity (measured in Ah) and the mower’s power draw. For small to medium lawns, a model with a 4.0 Ah or higher battery typically provides 30-60 minutes of mowing, which is usually sufficient. For larger lawns, consider models with larger batteries or multiple batteries to extend runtime. Remember, actual performance varies based on grass density and terrain, so choose a mower with a bit more capacity than you think you’ll need.

Are gas self propelled mowers suitable for small yards?

While gas mowers deliver high power, they are often heavier, louder, and require more maintenance—traits that may be unnecessary for small lawns. For compact areas, electric or battery-powered models tend to be more convenient, easier to start, and quieter. If you prefer gas for its durability or existing fuel supply, select a lightweight model with a smaller engine to reduce fatigue and handling issues.

What maintenance do self propelled gas mowers typically need?

Gas mowers require regular oil changes, spark plug replacements, and air filter cleaning or replacement. The blades also need periodic sharpening to maintain cutting efficiency. Additionally, you should drain or stabilize fuel during off-seasons to prevent engine issues. Proper maintenance extends the lifespan of the mower and keeps it running smoothly, but it does add to ongoing costs and effort compared to electric models.

How important are adjustable speed settings on a self propelled mower?

Adjustable speed controls are very useful, especially if you mow uneven terrain or have physical limitations. Slower speeds improve control, while higher speeds can make mowing larger lawns more efficient. They also help prevent fatigue during longer sessions. If you have a varied landscape or want more control over your mowing experience, prioritize models with multiple speed options.

Is a 3-in-1 cutting system worth the extra cost?

A 3-in-1 system, allowing mulching, bagging, and side discharge, provides versatile mowing options that help manage different grass types and conditions more effectively. However, these systems can add complexity and cost. If your lawn has diverse needs, this feature pays off by giving you more control over grass clippings and lawn appearance. For simple, small lawns, a basic model without this feature may suffice.

Conclusion

For those seeking the best overall performance, the Greenworks 60V 21 in Self-Propelled Lawn Mower offers a balanced mix of power, convenience, and value. If budget is a concern, mid-range gas models like the PowerSmart 170cc series provide strong performance without breaking the bank. Beginners or homeowners with smaller lawns should consider electric options with straightforward features, such as the Greenworks 40V model. For larger or more challenging terrains, investing in a premium gas model like the YARDMAX 22” with CVT ensures durability and power. Ultimately, your choice depends on your lawn size, preferred fuel type, and desired features—matching the mower to your specific needs leads to the best mowing experience.
