The Greenworks model is priced at $279.99, while the WORX model is available for $359.99, making the Greenworks mower about 17% cheaper. Each mower offers unique features catering to different user needs and preferences.

Design and Build

The design of both mowers emphasizes user comfort and efficiency. The Greenworks mower is ultra-lightweight, weighing 35% less than comparable models, making it easier to maneuver in tight spaces and around obstacles. It features a 16-inch cutting deck which is ideal for smaller lawns. Conversely, the WORX mower boasts a larger 21-inch cutting deck, making it suitable for bigger yards, up to half an acre. Its Aerodeck technology enhances airflow within the cutting deck, significantly improving cut quality and efficiency. Both mowers cater to different lawn sizes and user preferences, showcasing their respective strengths in design.

Power and Performance

Power and runtime are crucial factors in evaluating lawn mowers. The Greenworks mower operates on a 4.0Ah battery, delivering up to 40 minutes of runtime, which is ample for small to medium lawns. The WORX mower comes equipped with two 5.0Ah batteries, offering a longer runtime of about 50 minutes, making it suitable for larger areas. Notably, the WORX features Intellicut technology, which adjusts cutting speed based on grass density, enhancing performance without draining battery life. This feature gives the WORX mower a distinct advantage in terms of adaptability to varying lawn conditions.

Cutting Efficiency

When it comes to cutting efficiency, both mowers have unique features that enhance their capabilities. The Greenworks mower utilizes a smart cut adjustment system, allowing users to adjust cutting heights between 1.25 inches and 3.375 inches. This flexibility is beneficial for maintaining different grass types. The WORX mower, on the other hand, offers a 7-position height adjustment ranging from 1.5 inches to 4 inches, catering to a variety of grass lengths. Additionally, the Aerodeck technology in the WORX mower prevents clogs and enhances cut quality, giving it an edge when dealing with thicker grass.

Maintenance and Operation

Maintenance is a significant consideration when choosing a lawn mower. The Greenworks mower promotes zero maintenance, eliminating costs associated with gas, oil, and engine tune-ups. This translates to annual savings of over $200 compared to gas mowers, making it a budget-friendly option. The WORX mower, while also designed for electric use, includes features like a charge-level indicator, which provides real-time updates on battery status. This can help users manage their mowing sessions more effectively. Both mowers are designed to provide hassle-free operation, but the Greenworks model's maintenance-free aspect may appeal more to budget-conscious users.

Additional Features

Both mowers come equipped with features that enhance their usability and convenience. The Greenworks mower includes a grass bag for efficient clippings management and is compatible with over 75 other Greenworks 40V tools, promoting ecosystem versatility. The WORX mower offers 3-in-1 functionality, supporting mulching, bagging, and side discharging, which adds to its versatility. Its self-propelled feature with variable speed allows users to set their preferred pace, making mowing easier, especially on inclines. These additional features can significantly influence user satisfaction and overall mowing experience.

Price Comparison

Price is a crucial factor for many consumers. The Greenworks mower retails at $279.99, while the WORX mower is priced at $359.99. This $80 difference makes the Greenworks mower about 22% less expensive than the WORX model. Considering the features both offer, the Greenworks mower presents a compelling value proposition for those with smaller yards or those looking for a budget-friendly option. Meanwhile, the WORX mower, with its advanced technology and larger size, may justify its higher price for users with more extensive mowing needs.

Which should you buy?

Choosing between the Greenworks 40V 16" Cordless Lawn Mower and the WORX Nitro 21" Cordless Lawn Mower ultimately depends on individual needs. If you have a smaller lawn and prioritize ease of use and lower maintenance costs, the Greenworks mower is an excellent choice.
