Price Comparison
The Greenworks 80V 21" Self-Propelled Cordless Lawn Mower is priced at $479.99, while the PowerSmart EasyCut 18-Inch Gas Lawn Mower is significantly cheaper at $199.99, making it about 58% less expensive. This substantial price difference makes the PowerSmart mower an attractive option for budget-conscious buyers who need a reliable lawn care solution without breaking the bank. However, the higher cost of the Greenworks mower reflects its advanced features and technology, which may justify the investment for homeowners seeking a premium experience.
Performance and Power
In terms of performance, the Greenworks mower is equipped with a brushless motor that provides 30% more torque than standard models, allowing it to handle tougher lawn conditions and overgrown grass more effectively. It is designed to cut up to 1/2 acre on a fully charged 4.0Ah battery, making it ideal for larger lawns. Conversely, the PowerSmart mower features a 144cc OHV engine that delivers reliable performance for smaller tasks, particularly in tight spaces. While it can handle dense grass with its side discharge mechanism, it may not match the power and efficiency of the Greenworks model in demanding situations.
Cutting Width and Deck Size
The Greenworks mower has a cutting width of 21 inches, which allows for broader coverage in a single pass, potentially reducing mowing time for larger areas. In contrast, the PowerSmart mower has a smaller 18-inch cutting deck, which is suitable for managing smaller yards or intricate landscapes. The difference in deck size reflects the intended use of each mower; the Greenworks model is tailored for larger properties, while the PowerSmart is ideal for those with compact spaces.
Features and Functionality
The Greenworks mower is equipped with a 4-in-1 cutting system, allowing for mulching, bagging, side discharge, and turbo leaf pickup, offering versatility for different lawn care needs. Its LED headlights enhance visibility during early morning or late evening mowing sessions, providing added convenience. On the other hand, the PowerSmart mower also includes a side discharge feature but lacks the same level of versatility with a 2-in-1 capability (side discharge and mulch). This difference in features may influence buyers who prioritize adaptability in their lawn care equipment.
Ease of Use and Maneuverability
Maneuverability is a key factor in lawn mowers, and both models offer unique advantages. The Greenworks mower's self-propelled design, combined with rear-wheel drive and variable speed control, allows for maximum traction and ease of handling on uneven terrain. This makes it user-friendly, especially for those who may struggle with pushing a traditional mower. The PowerSmart mower, with its lightweight design and 8-inch rear and 7-inch front double ball-bearing wheels, is also easy to maneuver, particularly in tight corners. However, it requires manual effort, which may be a consideration for some users.
Maintenance and Care
When it comes to maintenance, the Greenworks cordless mower eliminates the hassle of gas and oil changes, making it a low-maintenance option that is convenient for users. The brushless motor is designed for longevity, providing quieter operation and reducing the need for frequent servicing. In comparison, the PowerSmart mower requires standard maintenance associated with gas engines, such as oil changes and spark plug replacements, which may add to the long-term cost and effort involved in lawn care.
Environmental Impact
The Greenworks mower stands out in terms of environmental considerations, as it operates on electric power, producing zero emissions during use. This makes it a more eco-friendly choice for homeowners concerned about their carbon footprint. The PowerSmart mower, being gas-powered, emits fumes and has a greater environmental impact. For buyers prioritizing sustainability, the Greenworks mower offers a clear advantage in this area.
Which should you buy?
Ultimately, the choice between the Greenworks 80V 21" Self-Propelled Cordless Lawn Mower and the PowerSmart EasyCut 18-Inch Gas Lawn Mower depends on individual needs and preferences. The Greenworks model is ideal for those willing to invest more for advanced features, superior performance, and environmental benefits, particularly for larger lawns. In contrast, the PowerSmart mower is a budget-friendly option that serves well for smaller spaces and less demanding tasks. Weighing the features against your specific lawn care requirements will help you make the best decision for your mowing needs.
