Winnowl Verdict
We just finished the audit on the Greenworks 48V Battery Powered Self-Propelled Lawn Mower and it landed a MEDIOCRE (54) 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 Mediocre 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 48V Battery Powered Self-Propelled Lawn Mower (21-Inch, Two 5.0Ah Batteries, Blower Combo Kit), you'll likely notice you might lack the torque needed to maintain blade speed when cutting thick, damp, or overgrown grass since the Battery Voltage is only 24 V—that's actually 47% below what we usually see from the competition. You might want to do a hard pivot from this Brand Tax product because the 9% higher price tag results in 25% less hardware for your dollar than the class average—there are definitely better ways to spend your money.

Performance Rating
Average
In its class, this product's performance is 27% below the average and earns a Mediocre Performance rating. It’s a bit of a mixed bag: the Number of Batteries indicates you should effectively eliminate any risk of downtime on massive yards by enabling a perpetual charge-and-swap rotation, but you may find that the 24 V Battery Voltage means that you might lack the torque needed to maintain blade speed when cutting thick, damp, or overgrown grass—so just make sure that's a trade-off you're okay with.
