Overview of the Greenworks 80V 21” Brushless Lawn Mower
The Greenworks 80V 21” Brushless Lawn Mower is a more premium option, priced at $499.99. This model comes with a powerful brushless motor and offers a 3-in-1 cutting system that includes mulching, rear bagging, and side discharge. It features a robust 21-inch steel deck and is complemented by a leaf blower and string trimmer in a comprehensive package. With a sales rank of 16,803, this mower is well-regarded for its performance and versatility in lawn care tasks.
Power and Performance Comparison
In terms of power, the BLACK+DECKER mower is equipped with a 13 Amp motor, while the Greenworks model boasts an impressive 80V brushless motor. This significant difference suggests that the Greenworks may handle thicker grass and tougher conditions more effectively than its counterpart. The BLACK+DECKER, while powerful for its size, is tailored for lighter mowing tasks. The performance difference is particularly notable when considering the Greenworks' ability to maintain efficiency across various yard conditions.
Cutting Versatility
Both mowers offer versatility in cutting options, but they cater to slightly different needs. The BLACK+DECKER mower provides a 3-in-1 system that includes mulching, bagging, and side discharge, making it suitable for homeowners looking for simplicity and efficiency. In contrast, the Greenworks model also features a 3-in-1 cutting system but includes an additional comprehensive package with a leaf blower and string trimmer, adding to its versatility. This package makes it more appealing for those looking to invest in an entire lawn care solution rather than just a single mower.
User Experience and Convenience
User experience is a crucial aspect of lawn mowers, and both models offer ease of use, albeit in different ways. The BLACK+DECKER mower features a single lever height adjustment with seven settings ranging from 1 1/2 inches to 4 inches, which allows for easy customization based on grass length. Additionally, its lightweight design enhances maneuverability. Conversely, the Greenworks mower also has a 7-position height adjustment and comes with LED lights for visibility in low-light conditions, showcasing a user-friendly approach that prioritizes comfort and convenience.
Battery and Power Source
The BLACK+DECKER mower is corded, which provides consistent power as long as it is plugged in, but limits mobility. The Greenworks mower, on the other hand, is cordless and powered by two 2Ah batteries, offering the freedom to move without being tethered to an outlet. This cordless feature makes the Greenworks model more appealing for larger yards or those with multiple obstacles. The convenience of rapid charging with the Greenworks kit adds to its appeal, allowing for quick recharges between uses.
Warranty and Longevity
Warranty and longevity are important factors when considering lawn mowers. The BLACK+DECKER mower comes with a 2-year warranty, providing a reasonable level of assurance for buyers. In contrast, the Greenworks mower offers a more generous 4-year warranty, which may indicate a greater confidence in the product’s durability and performance. This extended warranty could be a significant factor for consumers seeking a long-term investment in their lawn care equipment.
Which should you buy?
When deciding between the BLACK+DECKER 20-Inch Corded Electric Lawn Mower and the Greenworks 80V 21” Brushless Lawn Mower, several key differences emerge. The BLACK+DECKER mower is about 48% cheaper at $259.00 compared to the Greenworks model at $499.99, making it an attractive option for budget-conscious buyers. However, the Greenworks offers superior power, versatility, and additional features, including the leaf blower and trimmer, which may justify its higher price for those with larger or more complex lawns. Ultimately, the choice depends on your specific lawn care needs, budget, and preferences regarding convenience and performance.
