Winnowl Index

Winnowl Verdict

We just finished the audit on the Greenworks 40V 19" Brushless (Push) Cordless Lawn Mower and it landed a MEDIOCRE (60) Winnowl Index, which is a score that unfortunately reflects more "brand" than "benefit" when you compare the high price to the average specs. This one hits the Average Performance and Mediocre Value marks, but because it's from a brand with Strong Brand Strength, you have to decide if the reputation is worth the extra cost. With the Greenworks 40V 19" Brushless (Push) Cordless Lawn Mower, 4.0Ah Battery and Charger, you'll likely notice you should have just enough power to get the job done, but you lack a backup if the grass is thicker than expected since the Number of Batteries is only 1 count—that's actually 36% below what we usually see from the competition. You might want to do a hard pivot from this Brand Tax product because the 56% higher price tag results in 39% less hardware for your dollar than the class average—there are definitely better ways to spend your money.

Honestly, compared to other options out there, this product's performance is 10% above the average and earns an Average Performance rating. While the Total Run Time indicates you should be able to manage a typical quarter-acre property on a single charge if the grass is dry and maintained, the big catch is that the 1 count Number of Batteries means that you should have just enough power to get the job done, but you lack a backup if the grass is thicker than expected is something you'll just have to deal with.
