Price Comparison
The Greenworks 60V 21" Self-Propelled Cordless Lawn Mower is priced at $538.00, while the PowerSmart 21-Inch 3-in-1 Gas Self-Propelled Lawn Mower is significantly cheaper at $297.49, making it about 45% less expensive. This substantial price difference may be a key factor for budget-conscious consumers. While the Greenworks mower offers advanced features and technology, such as a brushless motor and dual batteries, the PowerSmart provides a reliable gas option at a fraction of the cost. If you're looking for value and basic functionality, the PowerSmart presents a compelling case.
Power Source
The Greenworks mower operates on a powerful 60V battery system, which provides gas-like performance without the emissions associated with gasoline engines. It includes two 4.0Ah batteries, enabling a runtime of over 60 minutes on a single charge, making it suitable for larger lawns. In contrast, the PowerSmart lawn mower is powered by a 170cc OHV engine, known for its durability and consistent performance. While gasoline engines can be less eco-friendly, they often deliver continuous power without concerns about charging. Your choice here will depend on whether you value battery convenience and eco-friendliness or the straightforward nature of gasoline power.
Cutting Efficiency
In terms of cutting efficiency, the Greenworks mower features a 21-inch cutting width and offers a 4-in-1 versatility that includes mulching, bagging, side discharge, and turbo leaf pickup. This versatility allows for tailored lawn care based on your needs. The PowerSmart also has a 21-inch cutting width and provides a 3-in-1 function for bagging, mulching, and rear discharge. However, it lacks the additional turbo feature of the Greenworks. Both mowers can handle medium to large yards, but the Greenworks offers more options for how to manage clippings, which might appeal to homeowners looking for flexibility.
Maintenance and Durability
The Greenworks mower promotes a maintenance-free experience, operating three times quieter than gas mowers and featuring waterproof construction that withstands various weather conditions. Additionally, it boasts rust-proof aluminum components for long-term durability. On the other hand, the PowerSmart mower, built with a robust steel deck, is designed for durability but may require more routine maintenance typical of gas-powered machines, such as oil changes and spark plug replacements. If you prefer a low-maintenance option with less noise and more eco-friendliness, the Greenworks mower stands out.
Ease of Use
User experience is crucial when choosing a lawn mower. The Greenworks mower features effortless self-propelled control, allowing you to tackle slopes and thick grass with ease. It also has an adjustable rear-wheel drive for optimal pace control. In comparison, the PowerSmart mower provides a self-propelled function with large rear wheels for better traction on uneven terrains. While both mowers are designed for user convenience, the Greenworks offers a more advanced and customizable experience, particularly for those who may struggle with pushing heavier machines.
Storage and Portability
When it comes to storage and portability, the Greenworks mower has EZ Fold handles that collapse vertically, allowing for easy storage in tight spaces like garages or sheds. The PowerSmart mower does not highlight any folding capabilities, which could make it less convenient for users with limited storage options. Considering that both mowers are designed for medium to large yards, the Greenworks mower’s compact storage solution may be more appealing to those with space constraints.
Brand Reputation and Sales Rank
Brand reputation can significantly influence buyer decisions. Greenworks has established itself as a leader in battery-powered outdoor equipment, and its mower is ranked 5,665 in sales, indicating a solid customer preference. PowerSmart, while also a recognized brand, holds a sales rank of 7,264, suggesting it may not be as widely favored as Greenworks in the competitive lawn mower market. A strong sales rank can reflect customer satisfaction and reliability, which may sway buyers towards the Greenworks mower.
Which should you buy?
Choosing between the Greenworks 60V 21" Self-Propelled Cordless Lawn Mower and the PowerSmart 21-Inch 3-in-1 Gas Self-Propelled Lawn Mower ultimately depends on individual needs and preferences. If you prioritize advanced features, eco-friendliness, and low maintenance, the Greenworks mower is a superior choice, albeit at a higher price point. However, if budget is your main concern, and you prefer a reliable gas-powered option for straightforward mowing tasks, the PowerSmart mower is an excellent value. Consider your lawn care needs, budget, and preference for power source to make the best decision for your yard.
