Price Comparison

This makes the Sun Joe about 50% cheaper than the Greenworks mower. If budget is your primary concern, the Sun Joe provides significant savings without sacrificing essential lawn care functionality. While both products are designed for lawn maintenance, the price difference reflects the varying capabilities and power sources of each product. The Greenworks mower offers a cordless, battery-powered solution, which often comes at a premium, compared to the corded nature of the Sun Joe.
Power and Performance
The Greenworks mower features a robust 40V battery system that provides up to 40 minutes of runtime, making it suitable for small to medium lawns. In contrast, the Sun Joe operates with a 12-amp motor, delivering consistent power for dethatching and scarifying with a 12.6-inch cutting width. The Greenworks mower's battery allows for gas-like performance without the hassle of cords, while the Sun Joe’s high-powered motor makes it efficient for lawn care tasks. Depending on your needs, if you prefer the freedom of movement offered by a cordless mower, the Greenworks is the better choice, but for heavy-duty lawn care, the Sun Joe's power is impressive.
Design and Usability
The Greenworks mower boasts an ultra-lightweight design that is 35% lighter than similar mowers, making it easy to maneuver, especially in tight spaces. Its ergonomic handles and push-button start enhance user comfort and convenience. Conversely, the Sun Joe is designed as a heavy-duty dethatcher and scarifier, emphasizing a sturdy build and functionality over portability. While the Greenworks mower prioritizes ease of use, the Sun Joe focuses on effective lawn maintenance. Users who value lightweight and agile tools will likely prefer the Greenworks, while those needing robust lawn care capabilities might find the Sun Joe more suitable.
Maintenance and Care
The Greenworks mower is marketed as a zero-maintenance device, eliminating gas and oil costs, emissions, and the need for engine tune-ups. This can save users over $200 annually compared to traditional gas mowers. On the other hand, the Sun Joe requires regular maintenance typical of electric tools but still offers a hassle-free experience compared to gas-powered options. If ease of maintenance is a priority, the Greenworks mower stands out for its cost-saving features. However, the Sun Joe's design allows for easy cleanup with its 8-gallon detachable collection bag, making it efficient for managing lawn debris.
Cutting and Aeration Features
The Greenworks mower features a 16-inch cutting deck with a smart cut adjustment system, allowing users to adapt to various grass types with a single-lever height control. It also includes a 2-in-1 mulching and rear-bagging system for optimal clippings management. The Sun Joe excels in aeration with its customizable 5-position depth control, which promotes healthier grass by improving airflow and nutrient absorption. While the Greenworks focuses on cutting efficiency, the Sun Joe aims to enhance lawn health through its dethatching capabilities. For those who prioritize cutting versatility, the Greenworks may be preferable, while the Sun Joe is ideal for deep lawn care.
Eco-Friendliness
The Greenworks mower champions eco-friendliness, providing a gas-free alternative that contributes to a cleaner environment with whisper-quiet operation. This makes it an excellent choice for homeowners in community settings where noise restrictions may apply. The Sun Joe, being electric and not gas-powered, also supports a more eco-friendly approach to lawn maintenance, though it is inherently limited by the need for a power cord. If environmental impact is a key factor in your purchasing decision, both products offer cleaner alternatives to traditional gas mowers, but the Greenworks takes a slight edge with its emphasis on battery operation and reduced emissions.
Warranty and Support
The Greenworks mower comes with a comprehensive warranty, including a 3-year tool and battery warranty, ensuring peace of mind for buyers regarding durability and service. The Sun Joe's warranty details weren’t specified, but it is common for electric tools to offer a standard warranty period. This difference can be crucial for those who want long-term assurance in their investment. With a robust warranty, the Greenworks mower not only provides quality performance but also confidence in its longevity, making it a strong contender for those looking to invest in reliable lawn care equipment.
Which should you buy?
Ultimately, the choice between the Greenworks 40V 16" Cordless Lawn Mower and the Sun Joe Corded Electric Dethatcher & Scarifier hinges on your specific lawn care needs and preferences. If you require a lightweight, cordless solution for small to medium lawns and prioritize ease of use, the Greenworks mower presents a compelling option with its innovative design and eco-friendly features. However, if you seek a powerful, cost-effective tool for extensive lawn care, the Sun Joe offers significant savings and effective dethatching capabilities. Consider your lawn size, maintenance routine, and budget to determine which product aligns best with your outdoor needs.
