At a price of $279.99, it offers convenience without the hassle of cords or gas, making it a great choice for small to medium-sized yards. Its design emphasizes ease of use and minimal maintenance, appealing to homeowners who prioritize a quiet mowing experience.

This mower provides up to 35 minutes of runtime on a single charge and features a 2-in-1 capability to mulch or bag grass clippings. Additionally, its lightweight design allows for easy maneuvering, while the steel deck ensures durability. With a sales rank of 5110, it has gained popularity among users seeking a reliable and eco-friendly mowing solution.

Overview of the PowerSmart 21-Inch Gas Self-Propelled Lawn Mower

The PowerSmart 21-Inch 3-in-1 Gas Self-Propelled Lawn Mower is priced slightly higher at $297.49 and is powered by a robust 170cc OHV engine. This mower is designed for efficiency, making it suitable for medium to large yards. Its self-propelled feature and larger cutting width of 21 inches make it ideal for tackling tougher mowing jobs with ease.

The mower's versatility is highlighted by its 3-in-1 functionality, enabling users to bag, mulch, or rear-discharge grass clippings. It also offers six cutting height adjustments, allowing for tailored grass management based on user preferences. With a sales rank of 7264, it appeals to those looking for a durable and effective gas-powered option.

Performance Comparison

In terms of performance, the Greenworks 40V 17" Cordless Lawn Mower boasts a brushless motor that provides higher torque and longer motor life with 30% less noise compared to gas mowers. This feature leads to a quieter mowing experience and eliminates the need for maintenance like oil changes. On the other hand, the PowerSmart mower's 170cc OHV engine is known for its consistent performance, making it a reliable choice for tougher mowing tasks.

While the Greenworks mower offers about 35 minutes of runtime, the PowerSmart mower’s gas engine allows for continuous operation without the worry of battery life. This difference is crucial for those who have expansive lawns that require longer mowing sessions. Therefore, while the Greenworks excels in quiet operation and ease of use, the PowerSmart provides the power and endurance needed for larger jobs.

Cutting Width and Versatility

The Greenworks mower features a cutting width of 17 inches, making it suitable for smaller yards where maneuverability is key. Its ability to switch between mulching and bagging enhances its versatility, allowing users to choose how they want to manage their grass clippings based on their lawn care preferences.

In contrast, the PowerSmart mower has a larger cutting width of 21 inches, which reduces mowing time, particularly in medium to large yards. It also offers three functions: bagging, mulching, and rear discharge. This versatility gives it an advantage for homeowners who want flexibility in managing their lawn waste. Overall, the PowerSmart is better suited for users needing a more extensive cutting path and varied functions.

Ease of Use and Maneuverability

When it comes to ease of use, the Greenworks 40V mower is designed for lightweight maneuverability, which is advantageous for navigating around obstacles in small yards. Its push-button start eliminates the hassle of pull cords, making it user-friendly, especially for those who may struggle with traditional gas mowers.

The PowerSmart mower, while heavier due to its self-propelled capability, offers large rear wheels that provide excellent traction and maneuverability on slopes or uneven terrain. This feature can make mowing less physically demanding, particularly for users who need to manage larger properties. Therefore, while the Greenworks is easier to handle for small yards, the PowerSmart’s self-propelled design may appeal to those with more extensive and challenging terrains.

Maintenance and Longevity

Maintenance is a significant consideration when choosing a lawn mower. The Greenworks mower has the advantage of requiring no oil or gas, which means minimal upkeep—just charge the battery and mow. This low-maintenance feature is appealing for users who want a hassle-free experience.

Conversely, the PowerSmart mower, being gas-powered, will require routine maintenance, such as oil changes and fuel refills. However, its robust 170cc engine is built for durability, which can be a significant factor for users who prioritize longevity and performance in demanding conditions. Thus, while the Greenworks offers a maintenance-free experience, the PowerSmart may be better suited for those who value performance and are willing to invest time in upkeep.

Price Comparison

The Greenworks 40V mower is priced at $279.99, making it about 6% cheaper than the PowerSmart mower, which retails for $297.49. This price difference may influence buyers who are looking for a cost-effective solution for small to medium yards. Additionally, the Greenworks mower's price has shown a notable average of $342.35 over the past 90 days, indicating potential savings for consumers.

On the other hand, the PowerSmart mower has an average price of $336.97 over the same period, suggesting that while it is slightly more expensive upfront, it may provide long-term value for those with larger lawns or specific mowing needs. Ultimately, the choice may come down to budget considerations and intended use.

Which should you buy?

Choosing between the Greenworks 40V 17" Cordless Lawn Mower and the PowerSmart 21-Inch Gas Self-Propelled Lawn Mower depends largely on your specific needs and lawn size. If you prioritize a quieter, eco-friendly approach for a small to medium-sized yard, the Greenworks mower is a sound investment, especially given its lower price of $279.99.
