Earthwise 1715-16EW 16-Inch 7-Blade Push Reel Lawn vs PowerSmart 21-Inch 3-in-1 Gas Self-Propelled Lawn
Updated July 2026 — full head-to-head comparison.
Overview of the Earthwise 1715-16EW and PowerSmart 21-Inch Mowers
The Earthwise 1715-16EW is priced at $122.99, making it about 59% cheaper than the PowerSmart 21-Inch, which costs $297.49. This significant price difference highlights two distinct approaches to lawn care: the manual, environmentally friendly reel mower versus the powerful, gas-powered self-propelled mower.
The Earthwise mower offers a 16-inch cutting width and operates without any fuel emissions, targeting eco-conscious users. On the other hand, the PowerSmart mower, with its 21-inch cutting width and robust 170cc OHV engine, is designed for users who need to efficiently manage larger lawns while also having the option to mulch, bag, or discharge clippings.
Design and Build Quality
In terms of design, the Earthwise 1715-16EW features a durable steel side plate, emphasizing longevity and strength. Its lightweight construction and composite wheels make it easy to maneuver, particularly in smaller spaces. Conversely, the PowerSmart 21-Inch boasts a robust steel deck that is engineered to handle tougher mowing conditions, making it suitable for medium to large yards.
While the Earthwise mower provides a traditional push reel experience, the PowerSmart model’s self-propelled feature with rear-wheel drive enhances its ability to navigate uneven terrains. This difference in design reflects the intended user experience; the Earthwise mower is perfect for those who prefer a hands-on approach, while PowerSmart targets users looking for efficiency and power.
Cutting Performance
When it comes to cutting performance, the Earthwise 1715-16EW offers a 7-blade ball bearing reel that stays sharp longer, providing a clean cut for various grass types, including Bermuda and Zoysia. The adjustable cutting height ranges from 0.5 inches to 2.5 inches, allowing users to achieve a neat finish.
In contrast, the PowerSmart 21-Inch mower features a 21-inch cutting width and can adjust to six cutting heights ranging from 1.5 inches to 3.9 inches. This versatility is ideal for adapting to different grass lengths and seasonal needs, making it more suitable for diverse mowing conditions. The wider cutting path of the PowerSmart model could lead to reduced mowing time, particularly in larger yards.
Ease of Use
The Earthwise 1715-16EW is designed for ease of use, requiring no gas or oil, which means less maintenance and no emissions. This makes it an excellent choice for those who prefer a straightforward mowing experience without the hassle of fuel. However, being a push mower, it does require physical effort, which may not be suitable for all users.
On the other hand, the PowerSmart 21-Inch’s self-propulsion feature significantly reduces the effort needed to mow, especially on inclines or uneven surfaces. The 10-inch large rear wheels provide excellent traction, enhancing maneuverability and making it easier to handle larger lawns. This ease of use is complemented by its 3-in-1 functionality, allowing users to switch between bagging, mulching, and rear discharging effortlessly.
Environmental Impact
The Earthwise 1715-16EW is an eco-friendly option that operates without any carbon emissions, making it a sustainable choice for environmentally conscious consumers. It promotes a quieter, more peaceful mowing experience, aligning well with the growing trend towards green living.
In contrast, the PowerSmart 21-Inch, while powerful and efficient, relies on gas, which contributes to emissions. However, it offers functionalities like mulching, which can help reduce yard waste and promote healthier grass growth. The environmental impact of both mowers caters to different priorities; users seeking zero emissions will lean towards the Earthwise, while those prioritizing power and versatility may opt for the PowerSmart.
Cost Efficiency
With a current price of $122.99, the Earthwise 1715-16EW is significantly more cost-effective than the PowerSmart 21-Inch, which is priced at $297.49. This approximately $174.50 difference in price could be a deciding factor for budget-conscious consumers.
Moreover, the Earthwise mower's lack of fuel requirements leads to lower ongoing operational costs, making it a financially sound choice in the long run. The PowerSmart, despite its higher initial investment, may save time and effort, which can be valuable for those with larger lawns. Therefore, the cost efficiency of each mower varies based on the user's lawn size and maintenance preferences.
Maintenance Requirements
The Earthwise 1715-16EW is almost maintenance-free, requiring no gas, oil, or spark plugs, making it a hassle-free option for users who dislike regular upkeep. The simplicity of its design means that users can focus more on mowing rather than maintenance.
Conversely, the PowerSmart 21-Inch requires more attention due to its gas engine. Users must ensure regular oil changes, spark plug maintenance, and fuel management, which adds to its overall maintenance requirements. However, its robust construction and performance may justify the extra effort for those needing a powerful mower for larger areas.
Which should you buy?
Choosing between the Earthwise 1715-16EW and the PowerSmart 21-Inch ultimately depends on your lawn care needs and preferences. If you have a small to medium lawn and prioritize eco-friendliness and low maintenance, the Earthwise model is an excellent choice. However, if you manage a larger yard and seek efficiency, power, and versatility, the PowerSmart mower may be the better option despite its higher price. Evaluating your lawn size, maintenance preferences, and environmental considerations will guide you to the right decision.
