Overview of the Products
The Greenworks 13 Amp 14-Inch Corded Dethatcher / Scarifier and the RB 9" Small Lawn Mower for Small Spaces cater to different lawn care needs.

Design and Usability
In terms of design, the Greenworks dethatcher/scarifier is lightweight and easy to maneuver, featuring a push-button start for convenience. It includes a 14-inch working path, which makes it suitable for larger areas. On the other hand, the RB mower is ultra-light at just 11.5 lbs without the battery, making it exceptionally easy to handle in tight spaces.
The Greenworks model allows for quick attachment changes between dethatching and scarifying modes, which adds versatility to its use. In contrast, the RB mower provides advanced one-hand steering, making it ideal for navigating small yards. Both products emphasize user-friendliness, but their designs cater to different gardening tasks.
Performance Capabilities
Performance is a key differentiator between the two tools. The Greenworks dethatcher/scarifier operates at a no-load speed of 3200 RPM and features a 3-position tine depth adjustment, enabling effective thatch removal for healthy lawn growth. It’s perfect for preparing your lawn for planting or maintenance.
Conversely, the RB mower is powered by a high-speed 6000 RPM brushless motor, making it highly efficient for grass cutting with zero maintenance. It’s designed to handle lawns up to 540 square feet, which is ideal for smaller spaces. These performance capabilities highlight the specific roles each tool plays — the Greenworks tool is for lawn health, while the RB mower focuses on grass cutting and maintenance.

It’s ideal for those focused on gardening and lawn care, particularly during the early spring or fall seasons.
In contrast, the RB mower is aimed at individuals with limited lawn space or those new to lawn care.
