Winnowl Verdict
The Greenworks 40V 19" Brushless (Push) Cordless Lawn Mower just cleared our audit with a MEDIOCRE (65) Winnowl Index—a score that unfortunately reflects more "brand" than "benefit." This is an Average Performance and Weak Value product from a brand with Strong Brand Strength. With the Greenworks 40V 19" Brushless (Push) Cordless Lawn Mower, 4.0Ah Battery and Charger, the specs show that you should have just enough power to get the job done, but you lack a backup if the grass is thicker than expected due to Number of Batteries of 1 count, which sits 36% below the average. We recommend a hard pivot from this Brand Tax product; the 56% higher price tag results in 34% less hardware for your dollar than the class average.
