Winnowl Verdict
The Greenworks 80V 21" Brushless Cordless (Self-Propelled) Lawn Mower with a MEDIOCRE (67) Winnowl Index is really about buying a brand with Strong Brand Strength. This rating is driven by Greenworks maintaining Average Brand Trust and Average Brand Reliability that strengthens the Average Performance and Fair Value. At $479.00, the price aligns with the $658.14 average; while the Performance is a balance between top and bottom specs; for example the Battery Voltage of 80 V may mean you should be able to power through tall fescue and overgrown weeds without the motor struggling or bogging down while the Total Run Time of 45 minutes may mean you will likely be able to mow a typical front and back yard on one charge without having to stop to find a charger. This is a Safe Bet based on the Strong Brand Strength that is 8% above the average brand.
