Dimension comparison
Design and Build Quality
When it comes to design and build quality, the Greenworks 40V 16" Cordless Lawn Mower stands out with its ultra-lightweight construction, weighing 35% less than traditional mowers. This makes it easy to maneuver, especially for users who prioritize comfort during mowing. In contrast, the PowerSmart 21" 2-in-1 Push Lawn Mower weighs 62 lbs, which may be more cumbersome for some. The Greenworks model features a 16" cutting deck alongside ergonomic handles and a push-button start, enhancing user experience significantly. While both mowers are designed for efficiency, the Greenworks mower’s lighter weight and cordless functionality give it an edge in ease of use.
Power and Performance
The Greenworks mower excels in delivering gas-like performance through its powerful 40V battery, offering up to 40 minutes of continuous runtime on a full charge. This performance is complemented by its 2-in-1 mulching and rear-bagging system, which allows for efficient clipping management. On the other hand, the PowerSmart mower is equipped with a robust OHV 144cc engine, providing reliable power for consistent cutting performance. Although both mowers are designed to maintain small to medium lawns, the Greenworks model's gas-free operation allows for quieter mowing, making it ideal for residential areas where noise could be an issue.
Cutting Capabilities
In terms of cutting capabilities, the Greenworks 40V mower features a single-lever 5-position height control, allowing for adjustments between 1.25" and 3.375". This flexibility makes it suitable for various grass types and lawn conditions. Conversely, the PowerSmart mower offers a 6-position height adjustment ranging from 1.5" to 3.9", giving users a broader range of cutting options. While both mowers provide customizable cutting heights, the PowerSmart model may cater better to those who prefer a slightly taller finish. Ultimately, the choice between these mowers will depend on individual lawn care preferences.
Maintenance and Operation
Maintenance is significantly easier with the Greenworks 40V mower, as it requires no gas, oil, or engine tune-ups, which can lead to annual savings of over $200 compared to gas-powered mowers. It operates quietly, with noise levels below 75dB, allowing for comfortable use at any time of day. In contrast, the PowerSmart mower requires regular maintenance associated with its 144cc engine. However, it does include a start/stop control lever for enhanced safety during operation. For those looking to reduce maintenance hassle, the Greenworks mower is clearly the more convenient option.
Runtime and Efficiency
The Greenworks mower offers a runtime of up to 40 minutes with its 4.0Ah battery, which is sufficient for small to medium-sized lawns. It charges fully in just 2 hours, making it efficient for quick turnaround times. On the other hand, the PowerSmart mower operates continuously without the need for battery charging, but it does rely on fuel consumption, which could lead to higher operational costs. While both mowers are priced at $279.99, the Greenworks model’s cordless convenience and sustainable operation provide a more efficient mowing experience overall.
Price and Value
Both the Greenworks and PowerSmart mowers are available at the same price of $279.99. However, considering the average prices over the past 90 days, the Greenworks mower has an average price of $241.05, while the PowerSmart mower averages $266.99. This indicates that the Greenworks mower is approximately 10% cheaper on average, offering better value for those seeking to maximize their investment. Furthermore, the Greenworks model includes additional features like a battery, fast charger, and a comprehensive 3-year warranty for both the tool and battery, enhancing its overall value.
Customer Reception
The Greenworks mower ranks higher in sales, with a bestseller rank of 813 compared to the PowerSmart’s rank of 18759. This suggests that the Greenworks model is more popular among consumers, likely due to its reputation for quality, ease of use, and efficiency. Customer reviews often highlight its lightweight design and convenient cordless operation as key selling points. Meanwhile, the PowerSmart mower, while functional, does not seem to attract the same level of enthusiasm, possibly due to its heavier build and dependence on a gas engine.
Which should you buy?
Choosing between the Greenworks 40V 16" Cordless Lawn Mower and the PowerSmart 21" 2-in-1 Push Lawn Mower ultimately depends on your specific needs. If you prioritize lightweight design, gas-free operation, and lower maintenance, the Greenworks mower is the clear winner. Its superior runtime, ease of use, and higher customer satisfaction rates make it a compelling choice for most homeowners. However, if you prefer a traditional gas-powered mower with potentially more cutting height options, the PowerSmart model may be suitable. Overall, the Greenworks mower offers more value and performance for the price, making it the recommended option for modern lawn care.
