Winnowl Index
Winnowl Verdict
With its Performance ranking 33% below the average, the Greenworks 48V 21-Inch Brushless Self-Propelled Mower receives a MEDIOCRE (55) Winnowl Index. The Fair Value and Strong Brand Strength are completely offset by the Mediocre Performance making it difficult to justify this purchase. With the Battery Voltage coming in at just 24 V, the Greenworks 48V 21-Inch Brushless Self-Propelled Mower sits below what we usually see in this calss, which may mean you might lack the torque needed to maintain blade speed when cutting thick, damp, or overgrown grass. We recommend you look at other Battery Powered Self-Propelled Lawn Mowers to avoid the Mediocre Performance of this product.
