Price Comparison
When it comes to price, the Greenworks 40V 17" Cordless Lawn Mower is the more economical choice at $279.99, compared to the Greenworks 60V 21" Self-Propelled Cordless Lawn Mower, which retails for $538.00. This makes the 40V model about 48% cheaper than its 60V counterpart. If budget is a primary concern, the 40V mower provides significant savings while still offering solid performance for smaller yards. However, the additional features and power of the 60V mower may justify the higher price for those with larger lawns.
Power and Performance
The Greenworks 60V 21" Self-Propelled Lawn Mower boasts a powerful brushless motor that delivers gas-like power, allowing it to tackle larger yards of up to 3/4 acre per charge. In contrast, the 40V model is designed for small to medium yards, with a runtime of up to 35 minutes on a single charge. While the 40V mower is suitable for up to 1/4 acre, the 60V mower's enhanced power makes it a better option for those needing to cover more ground efficiently.
Cutting Versatility
Both mowers offer versatility in cutting options, but the Greenworks 60V model provides a more comprehensive four-in-one capability, allowing users to mulch, bag, side discharge, and turbo leaf pickup. The 40V model, while offering a 2-in-1 option of mulching or bagging, lacks the additional versatility of the self-propelled 60V mower. This expanded functionality makes the 60V mower more adaptable to various lawn care needs throughout the seasons.
Ease of Use
The Greenworks 60V 21" Self-Propelled Cordless Lawn Mower features a self-propelled design that allows users to tackle slopes and thick grass with ease, eliminating the need for pushing. This is especially beneficial for those with challenging terrains. In comparison, the 40V mower requires manual effort to push, which can be a consideration for users with mobility concerns or larger lawns. The self-propelled feature of the 60V mower adds a layer of convenience that may be worth the investment.
Noise Levels
Operating at significantly lower noise levels than gas mowers, the Greenworks 60V model is noted to be three times quieter than traditional gas mowers. Meanwhile, the 40V mower is also quieter, with claims of being 30% quieter than gas mowers. For users in noise-sensitive neighborhoods, either option would offer a peaceful mowing experience, but the 60V mower's additional noise reduction could enhance user satisfaction, especially during early morning or late evening mowing sessions.
Runtime and Battery Life
The Greenworks 60V mower, equipped with dual 4.0Ah batteries, provides an impressive runtime of over 60 minutes, covering larger areas without interruption. In contrast, the 40V mower includes a single 4.0Ah battery that offers up to 35 minutes of runtime. For homeowners with extensive lawns, the longer runtime of the 60V model means fewer battery changes and more efficient mowing, which can be a critical factor for busy users looking to maximize their lawn care efficiency.
Warranty and Support
Both mowers come with robust warranties, but the Greenworks 60V model offers a longer warranty period of four years for both the tool and battery, compared to the three-year warranty on the 40V model. This extended warranty reflects the confidence in the 60V mower’s durability and performance. Users looking for assurance in their investment may find the extra year on the 60V model appealing, especially for a higher-priced product.
Which should you buy?
Choosing between the Greenworks 40V 17" Cordless Lawn Mower and the Greenworks 60V 21" Self-Propelled Cordless Lawn Mower ultimately depends on your specific needs and budget. If you have a smaller yard and prefer a more economical option, the 40V mower at $279.99 is a solid choice, offering essential features for basic lawn care. However, for those with larger lawns or who seek enhanced performance and versatility, the 60V mower, despite its higher price of $538.00, provides superior power, runtime, and convenience with its self-propelled feature. Consider your lawn size, terrain, and how much you value ease of use to make the best decision for your mowing needs.
