Overview
When considering lawn care equipment, the BLACK+DECKER 20-Inch Corded Electric Lawn Mower and the Greenworks 13 Amp 14-Inch Corded Dethatcher/Scarifier serve different purposes but both aim to enhance the health and appearance of your lawn.

Understanding the unique features and capabilities of each product will help you decide which one best suits your lawn care needs.
Functionality
The BLACK+DECKER mower is designed for cutting grass with its powerful 13 Amp motor and 20-inch deck, offering three mowing modes: mulching, bagging, and side discharge. This versatility allows you to handle various lawn conditions effectively. On the other hand, the Greenworks dethatcher/scarifier specializes in lawn maintenance by removing thatch and debris with its 14-inch working width. This tool features a 2-in-1 design that allows for easy switching between dethatching and scarifying, which is essential for maintaining a healthy lawn.
Ease of Use
For ease of operation, both products offer user-friendly features. The BLACK+DECKER mower includes a single lever for height adjustment, allowing users to select from seven cutting heights ranging from 1.5 inches to 4 inches. This adaptability is crucial for achieving the desired grass length. In comparison, the Greenworks dethatcher/scarifier is lightweight and features an easy push-button start, making it simple to operate. Its 3-position tine depth adjustment allows users to customize the intensity of dethatching, ensuring optimal lawn health.
Performance
In terms of performance, the BLACK+DECKER mower excels with its 13 Amp motor that provides ample power for cutting through thick grass and overgrowth. The mower's EdgeMax deck design helps get close to edges, minimizing the need for a trimmer. Meanwhile, the Greenworks dethatcher/scarifier operates at a no-load speed of 3200 RPM, effectively removing matted layers from the lawn. Both products are effective in their respective tasks, but the mower is more geared toward cutting, while the dethatcher/scarifier focuses on soil and lawn health.
Maintenance
Maintenance requirements differ between the two products. The BLACK+DECKER mower comes with a 13-gallon fabric grass bag, which simplifies the process of collecting clippings and allows users to easily see when it is full. This feature can save time and enhance the mowing experience. In contrast, the Greenworks dethatcher/scarifier is designed for minimal upkeep, as it focuses on dethatching and scarifying. Its stainless steel tines are durable and require less frequent replacement, making it a practical choice for those who prioritize ease of maintenance.
Warranty
Warranty offerings can greatly influence purchasing decisions. The BLACK+DECKER mower includes a 2-year warranty, providing assurance of quality and durability. The Greenworks dethatcher/scarifier, however, boasts a longer 3-year warranty, which may give potential buyers more confidence in their investment. This extended warranty reflects Greenworks' commitment to customer satisfaction and product reliability.
Sales Rank
Sales rank can indicate a product's popularity and customer satisfaction. The BLACK+DECKER mower holds a sales rank of 31,868, while the Greenworks dethatcher/scarifier has a significantly better rank at 9,922. This suggests that the dethatcher/scarifier is a more popular choice among consumers, possibly due to its lower price point and specialized functionality, which may appeal to a wider audience.
Which should you buy?
Choosing between the BLACK+DECKER 20-Inch Corded Electric Lawn Mower and the Greenworks 13 Amp 14-Inch Corded Dethatcher/Scarifier depends on your specific needs. If you're looking for a robust mower that offers versatility in cutting options, the BLACK+DECKER mower is a strong contender with its multiple mowing modes and user-friendly height adjustments. However, if your primary focus is on maintaining a healthy lawn by removing thatch and debris, the Greenworks dethatcher/scarifier presents a cost-effective solution with its lightweight design and effective performance.
