Overview of the WORX Nitro 21" Cordless Lawn Mower
The WORX Nitro 21" Cordless Lawn Mower is priced higher at $379.99, but it offers distinct advantages for larger properties. It is equipped with a brushless motor that delivers 40% more power and 10% longer runtime compared to previous models.

Performance Comparison
In terms of performance, the WORX Nitro 21" outshines the Greenworks model. The Nitro is designed for larger lawns and can handle up to 1/2 acre, while the Greenworks is limited to 1/4 acre. The Nitro’s brushless motor provides 40% more power, which translates to better cutting efficiency, especially in thicker grass. The Greenworks, while effective for smaller yards, offers a shorter runtime at 35 minutes compared to the Nitro's 50 minutes. This significant difference makes the WORX a more robust choice for demanding mowing tasks.
Cutting Versatility
Both mowers provide versatility in cutting options, but the WORX Nitro has a slight edge. The Greenworks mower features a 2-in-1 system for mulching and bagging, allowing users to switch between modes with ease. In contrast, the WORX Nitro offers 3-in-1 functionality, which includes mulching, bagging, and rear side-discharging. This additional feature allows for greater flexibility in handling various grass types and lawn conditions. The Nitro also boasts a 7-position height adjustment lever, enabling more precise cutting height choices compared to the Greenworks’ 6 cutting heights.
Ease of Use and Maintenance
When it comes to ease of use, both mowers are designed for user-friendliness, but they cater to different needs. The Greenworks mower is lightweight and easy to maneuver, making it ideal for users with smaller yards. It includes a 3-year warranty on both the tool and the battery, which adds to its appeal for those concerned about long-term reliability. The WORX Nitro, while heavier due to its larger cutting deck, features a fully collapsible handle that allows for convenient storage and easy adjustments. The onboard charge-level indicator also enhances usability, keeping users informed about the remaining battery power.
Battery and Runtime
The Greenworks mower comes with a 4.0Ah battery, providing up to 35 minutes of runtime, which is adequate for smaller lawns. However, the WORX Nitro includes two 20V 5.0Ah batteries, which extend its runtime to approximately 50 minutes. This difference is crucial for users with larger yards, as the additional battery capability allows for extended mowing sessions without interruptions. Furthermore, the WORX batteries are compatible with over 140 other tools in the PowerShare platform, making them a more versatile investment for those who value multi-tool compatibility.
Pricing and Value
In terms of pricing, the Greenworks 40V 17" Cordless Lawn Mower is about 17% cheaper than the WORX Nitro, retailing at $279.99 compared to $379.99. While the lower price of the Greenworks makes it an attractive entry-level option, the WORX Nitro offers more features and capabilities that justify its higher price point. For those with larger properties or specific lawn care needs, the investment in the WORX may provide better long-term value. Additionally, the WORX Nitro is ranked higher in terms of sales at 4,856 compared to the Greenworks at 5,110, suggesting a slight preference among consumers for the WORX model.
Which should you buy?
Deciding between the Greenworks 40V 17" Cordless Lawn Mower and the WORX Nitro 21" Cordless Lawn Mower ultimately depends on your specific needs and lawn size. If you have a small to medium yard and are looking for an affordable, lightweight option, the Greenworks mower is an excellent choice. However, if you manage a larger lawn and require a more powerful mower with advanced features, the WORX Nitro provides superior performance and versatility, making it worth the higher price.
