Introduction to the Mowers

When it comes to cordless lawn mowers, the Greenworks 40V 17" Cordless Lawn Mower and the WORX Nitro 21" Cordless Lawn Mower are popular choices. Priced at $279.99 and $359.99, respectively, they cater to different needs and yard sizes. The Greenworks model is best suited for smaller areas, while the WORX model offers enhanced features for larger lawns.

Performance and Power

The performance of a lawn mower is critical for achieving a well-manicured lawn. The Greenworks mower is equipped with a brushless motor that delivers a runtime of up to 35 minutes on a single charge with the included 4.0Ah battery. In contrast, the WORX mower boasts a brushless motor 2.0 that provides 40% more power and 10% longer runtime than earlier models, with a maximum no-load runtime of 50 minutes using two 20V 5.0Ah batteries. This makes the WORX mower more suitable for larger lawns, as it can handle up to ½ acre effectively.

Cutting Technology

Both mowers feature advanced cutting technology to enhance their performance. The Greenworks mower offers 6 cutting heights, adjustable with a single lever, allowing for a customized mowing experience. Meanwhile, the WORX Nitro includes Aerodeck technology, which improves air volume in the cutting deck, preventing clogs and enhancing cut quality. This is particularly beneficial for tackling thick grass, making the WORX mower more efficient in diverse lawn conditions.

Versatility and Functionality

Versatility in lawn care tools can save time and effort. The Greenworks mower supports 2-in-1 functionality, allowing users to easily switch between mulching and bagging. The WORX model, however, takes this a step further with its 3-in-1 functionality, which includes mulching, bagging, and rear side-discharging options. This added flexibility makes the WORX mower more adaptable to different mowing preferences and lawn types.

Ease of Use

User-friendliness is a significant factor when choosing a lawn mower. The Greenworks mower is lightweight and designed for easy maneuvering, making it a great choice for small to medium yards. It includes a grass bag and operates at 50% less noise than gas mowers, enhancing the overall mowing experience. The WORX Nitro, on the other hand, features a self-propelled design with variable speed settings, allowing users to set their preferred speed up to 3.7 MPH. This self-propelled feature takes the strain out of mowing, especially on inclines.

Storage and Maintenance

Storage and maintenance can impact the long-term usability of a lawn mower. The Greenworks mower comes with a worry-free warranty of 3 years for both the tool and the battery, ensuring peace of mind. It is also compact, making it easy to store. The WORX mower features a fully collapsible handle for vertical storage, which saves valuable space. Both mowers require minimal maintenance, thanks to their brushless motors that eliminate the need for oil changes, but the WORX model's design may offer better durability due to its high-strength polymer deck.

Price Comparison

Price is a crucial consideration for many buyers. The Greenworks mower is priced at $279.99, making it about 17% cheaper than the WORX Nitro at $359.99. This price difference may appeal to those looking for a budget-friendly option. However, the additional features and improved performance of the WORX mower may justify the higher cost for buyers with larger lawns or specific mowing needs.

Which should you buy?

Ultimately, the choice between the Greenworks 40V 17" Cordless Lawn Mower and the WORX Nitro 21" Cordless Lawn Mower depends on individual needs. If you're looking for an affordable, lightweight mower for a small to medium yard, the Greenworks model is an excellent choice. However, for those with larger lawns or a desire for more advanced features, the WORX Nitro offers superior power, runtime, and versatility. Consider your yard size and mowing preferences to make the best decision.
