Priced at $259.00, this mower features a 13 Amp high-output motor that provides ample power for cutting through thick grass and overgrowth.

The 7-setting height adjustment enhances its usability, accommodating various grass lengths.
Overview of Greenworks 60V 21" Self-Propelled Cordless Lawn Mower
The Greenworks 60V 21" Self-Propelled Cordless Lawn Mower stands out with its advanced battery-powered design and self-propelled capabilities. At a price of $538.00, it boasts a 60V brushless motor that delivers gas-like power and can handle up to 3/4 acre per charge with two 4.0Ah batteries. This mower operates 60% quieter than gas models, making it ideal for residential areas. The self-propelled feature allows users to tackle slopes and thick grass with ease, a significant advantage for larger or more challenging yards.
Power and Performance Comparison
In terms of power, the BLACK+DECKER mower utilizes a 13 Amp electric motor, while the Greenworks mower features a 60V brushless motor. The Greenworks model is engineered for high performance, providing gas-like power and a cutting speed of 3200 RPM, which is particularly beneficial for larger lawns. Additionally, it offers an impressive runtime of over 60 minutes due to its dual battery system. This allows it to cover significant ground without interruption, making it suitable for expansive properties. In contrast, the BLACK+DECKER mower is more suited for smaller yards and is powered directly through an electrical outlet, which could limit mobility but ensures consistent power without battery management.
Cutting Versatility
The BLACK+DECKER mower offers three in one cutting versatility, allowing users to choose between mulching, bagging, or side discharge for grass clippings. This feature is particularly beneficial for those who prefer different lawn care methods throughout the mowing season. The Greenworks mower also provides multiple options, including mulching, bagging, and side discharge, emphasizing its 4-in-1 functionality. Both mowers feature adjustable cutting heights, but the Greenworks model provides a more advanced self-propelled feature that allows for tailored mowing experiences, especially in uneven terrain.
Ease of Use and Maintenance
The BLACK+DECKER mower is designed with user-friendliness in mind, featuring a simple single-lever height adjustment that allows for quick changes between seven different cutting heights. Additionally, it includes a 13-gallon fabric grass bag that makes it easy to check for fullness. The Greenworks mower also emphasizes ease of use with its self-propelled design, enabling effortless navigation across the yard. Its LED headlights allow for mowing in low-light conditions, and the IPX4-rated waterproof construction ensures durability during inclement weather. Both models require minimal maintenance compared to traditional gas mowers, but the Greenworks mower stands out for its quiet operation and eco-friendliness.
Storage and Portability
Storage and portability are essential factors when choosing a lawn mower. The BLACK+DECKER mower, while lightweight and easy to transport, may require careful management of the power cord during use. In contrast, the Greenworks mower features a space-saving design with EZ Fold handles that allow it to collapse vertically, making storage in tight spaces much simpler. This cordless design also means you can move freely without the constraints of a cord, enhancing the convenience of use, especially in larger yards.
Warranty and Customer Support
The BLACK+DECKER mower comes with a two-year warranty, which is standard for many power tools. In contrast, the Greenworks mower offers a more extensive four-year warranty for both the tool and the battery, indicating greater confidence in its long-term durability and reliability. This extended warranty could be a significant factor for those investing in a higher-priced mower, as it provides added peace of mind regarding potential repairs or issues.
Which should you buy?
Ultimately, the choice between the BLACK+DECKER 20-Inch Corded Electric Lawn Mower and the Greenworks 60V 21" Self-Propelled Cordless Lawn Mower depends on your specific needs and lawn size. If you have a smaller yard and prefer a more budget-friendly option, the BLACK+DECKER mower at $259.00 is a solid choice, offering reliable performance and versatility. However, for those with larger properties or specific challenges like slopes, the Greenworks mower, priced at $538.00, provides advanced features such as self-propulsion, longer run times, and quieter operation, making it a more suitable investment for extensive lawn care.
