Overview of the Products
The Greenworks 80V 21" Self-Propelled Cordless Lawn Mower is designed for homeowners seeking a powerful, efficient lawn care solution. In contrast, the STEELITE 40V 17-inch Electric Lawn Mower offers a more compact and versatile option, especially for smaller yards. The Greenworks mower comes in at $479.99, while the STEELITE is priced at $329.99, making it about 31% cheaper. Both products cater to different needs, emphasizing power versus versatility.
Performance Comparison
In terms of performance, the Greenworks mower features a brushless motor that delivers 30% more torque than standard models, enabling it to handle tough grass and uneven terrain effectively. This self-propelled mower can cut up to half an acre on a full charge, making it suitable for larger lawns. On the other hand, the STEELITE mower is powered by dual 20V 4.0Ah batteries, providing a runtime of up to 25 minutes. While the STEELITE is effective for smaller tasks, its performance may fall short for extensive mowing jobs compared to the Greenworks.
Cutting Options
The cutting capabilities of these two mowers differ significantly. The Greenworks mower features a 4-in-1 cutting system, allowing for mulching, bagging, side discharge, and turbo leaf pickup. This versatility makes it a great choice for homeowners who want multiple options for grass disposal. In contrast, the STEELITE offers a 2-in-1 bagging and mulching option, which is less comprehensive. While the STEELITE's features may suffice for casual users, the Greenworks provides greater flexibility for various mowing preferences.
Build Quality and Durability
When it comes to build quality, the Greenworks mower boasts a durable steel deck designed for longevity and resilience. It also features a self-propelled design with rear-wheel drive for enhanced maneuverability. The STEELITE, while lightweight at only 30 lbs, may not match the durability of its Greenworks counterpart. The Greenworks mower is designed for heavy-duty use, whereas the STEELITE may be better suited for light to moderate mowing tasks.
Ease of Use
Both mowers are user-friendly, but they cater to different preferences. The Greenworks mower includes high-visibility LED lights for early morning or late evening mowing, enhancing usability in various lighting conditions. It also offers variable speed control, allowing users to adjust the speed based on their comfort. The STEELITE mower simplifies operation with a push-button start and a foldable handle for easy storage. However, its more compact design makes it less suitable for those requiring extensive mowing capabilities.
Battery System and Runtime
The battery systems of the two mowers highlight their differences. The Greenworks mower operates with a 4.0Ah battery that is compatible with over 75 tools, offering a broader ecosystem for users. This mower can handle substantial lawn care tasks on a single charge. Conversely, the STEELITE mower comes with dual 20V 4.0Ah batteries, enabling it to deliver a maximum runtime of 25 minutes. For users with larger lawns, the Greenworks offers a significant advantage in battery life and compatibility with other tools.
Price and Value
In terms of pricing, the Greenworks mower is priced at $479.99, while the STEELITE is available for $329.99, making the STEELITE about 31% more affordable. However, the Greenworks mower justifies its higher price with superior performance, longer runtime, and enhanced versatility. While the STEELITE may be appealing for budget-conscious consumers or those with smaller yards, the Greenworks offers greater value for those needing a robust and reliable lawn care solution.
Which should you buy?
Choosing between the Greenworks 80V 21" Self-Propelled Cordless Lawn Mower and the STEELITE 40V 17-inch Electric Lawn Mower ultimately depends on your specific lawn care needs. If you have a larger yard and require a durable mower capable of handling tough conditions, the Greenworks mower stands out as the better option despite its higher price. However, if you have a smaller lawn and are looking for a budget-friendly, versatile tool, the STEELITE offers good value. Your decision should align with your lawn size, mowing frequency, and budget constraints.
