Overview of the Products

The Greenworks 80V 21” Brushless and WORX Nitro 21” Cordless Lawn Mower are both excellent choices for homeowners looking to maintain their lawns efficiently. Greenworks is priced at $499.99, while WORX offers its model at $359.99, making it about 17% cheaper. Both models feature advanced technology and robust performance, but they cater to slightly different user needs and preferences.

Performance and Power

When it comes to performance, the Greenworks mower features an 80V brushless motor, ensuring efficient and reliable operation for yard maintenance. In contrast, the WORX Nitro is equipped with a 40V brushless motor that delivers 40% more power than earlier models, making it suitable for lawns up to ½ acre. The Greenworks model, with its higher voltage, may provide a more robust performance in larger yards, while the WORX offers a balance of power and runtime, making it ideal for smaller spaces.

Battery Life and Charging

The Greenworks kit includes two 2Ah batteries and a rapid 4A charger, allowing for quick recharges and consistent power. Meanwhile, the WORX Nitro comes with two 20V 5.0Ah batteries, which provide a longer runtime of up to 50 minutes. This means the WORX may be better suited for extensive mowing sessions without frequent recharging. The rapid recharge capability of Greenworks' batteries is a plus, especially for users who prefer less downtime.

Cutting Technology

Both mowers feature advanced cutting technologies. The Greenworks mower offers a versatile 3-in-1 system for mulching, bagging, and side discharging, providing flexibility based on lawn care needs. Conversely, the WORX Nitro incorporates Aerodeck technology, which enhances air volume in the cutting deck to improve cut quality and efficiency. This feature is particularly useful for maintaining a clean cut and optimizing bag collection, presenting a significant advantage for users focused on lawn aesthetics.

User Experience and Comfort

User experience is paramount in lawn care, and both mowers excel in this area. The Greenworks mower features a hand-push design with a 7-position height adjustment, LED lights for low-light conditions, and vertical storage capability, all aimed at enhancing user comfort. The WORX Nitro, on the other hand, is self-propelled with variable speed settings, allowing users to guide it comfortably across different terrains. This self-propulsion feature can significantly reduce the physical effort required, making it a great choice for those with larger or hilly lawns.

Additional Features

In terms of additional features, the Greenworks kit includes a comprehensive package with a 500 CFM axial leaf blower and a 13” string trimmer, making it an all-in-one solution for yard maintenance. WORX, however, offers a more focused approach with its PowerShare platform, allowing users to utilize the same batteries across more than 140 different tools and outdoor equipment. This feature fosters versatility for users who may already own WORX products, enhancing overall value.

Warranty and Support

Warranty is an essential factor for any investment. The Greenworks mower comes with a generous 4-year warranty, providing peace of mind for buyers. The WORX Nitro's warranty details are not explicitly mentioned in the provided data, which may be a consideration for potential buyers looking for long-term reliability. A strong warranty can indicate the manufacturer's confidence in their product, making the Greenworks model a more reassuring choice for some consumers.

Price Comparison

The Greenworks 80V 21” Brushless is priced at $499.99, while the WORX Nitro 21” Cordless Lawn Mower retails for $359.99. This price difference of $140 highlights a significant cost-saving opportunity with the WORX model, which may appeal to budget-conscious consumers. However, potential buyers should weigh this savings against the features, performance, and additional tools offered by the Greenworks kit, as both models excel in different areas.

Which should you buy?

Choosing between the Greenworks 80V 21” Brushless and the WORX Nitro 21” Cordless Lawn Mower ultimately depends on your specific lawn care needs. If you prioritize a comprehensive yard maintenance solution with additional tools and a robust warranty, the Greenworks mower might be the better choice despite its higher price. However, if you're looking for a powerful, self-propelled mower that offers excellent runtime and value, the WORX Nitro stands out as a cost-effective option.
